Paul, it's 4 months later, I'm still watching. I'm sure hundreds of others too! You're a wonderful teacher.

[@user-zv3gi1yc3j]

Paul, I really like your approach to learning Fusion 360. I am a hobbyist, trying to learn some necessary techniques, but I don't come from a Mechanical Engineering, or Drafting background. As such, the way that I learn is perhaps different from a designer. Your approach is organized around the objective, rather than being around a specific action. This minor, perhaps subtle difference in your style has proven to be a very effective change in how I learn, and how quickly I learn. thank you for taking the time to put these videos together.

[@brendonfigg8294]

Hey Paul, I know you made these some time ago but I have been following all of your lessons and in the last three days I have gone from no idea what is was doing and loosing items into space to now im sketching and making 3d models of my kids toys. Love it. Thank-you

[@TheLoveAmbassadors]

LOOKING FORWARD TO LESSONS WITH YOU EVERYDAY!!!

[@deonholt]

Another superb tutorial again. I was where you were. I dropped F360 for about 6 weeks and after watching your first lesson, decided that I must just push through. I am so glad I did. Thanks a million.🏆👏

[@richardcorwin5529]

Mr. McWhorter, Thank you for producing relevant content. Through your meticulous teachings I have just finished my first paid design job! Even though I haven't had the need for gears and such I still learn a great deal on how to navigate Fusion 360. I am proof that this old dog can still learn new tricks!! Once again sir, thank you very much!

[@paulmcwhorter]

Glad you found the lessons helpful

[@AquarianAdventures]

How did you find your design job?

[@vitustillebeck4965]

I'm glad that i had the idea to make the herringbone gear by mirroring before you showed it. that means that i'm learning because of YOU Mr.Paul

[@alexandernagel2200]

Hi Paul, i have been off of Fusion 360 and rediscovered your tutorial and they are great and so helpful. Thanks for doing such great videos helping everyone interested to make it so simple.

[@paulmcwhorter]

Glad you like them!

[@fuzzballhall9313]

What an Amazing beginners guide for a complete beginner! Just started out with 360 FREE 2 weeks ago. There is a lot of really nice tutorials out there, but it doesn't even come close to your Lessons! Man Im glad to find your channel.

[@PaulLemars01]

Thank you Paul. Now I have a some more skills to work with. The thing I love about this is that your lessons are a jumping off point for further options.

[@ebptube]

Your lessons are great for getting into Fusion for an oldtimer newbie like me! Tanks a lot!

[@paulhumphrey3195]

I love your teachings I have watched all of these videos..... including arduino videos. I was screaming at the screen because in the pervious video you trimmed the circles right away and in this one I didn't think you were going to. I wish you were more consistent but you did(had to) clean it up anyhow. Please keep up the videos, I have learned allot.. And this should tell you we are learning thankyou.

[@timrobinson9192]

I can't overstate how much I am enjoying your brilliant tutorials in Fusion 360. I started at the very beginning and have gotten this far one one sitting, I am literally glued to your videos! Thank you so very, very much 👌👌👌👍👍👍

[@bobharris5872]

Paul, Thank you for doing these Videos. I'm new to Fusion 360 and I find that you are a good teacher. You have taken a lot of the curve out of learning.

[@Zone1242]

Another great lesson. I had some fun and games with this one. When I created the second (smaller) gear I forgot to make the first one left hand before doing the mirror action. The gear looked fine. Whe I printed it off however I quiclky discovered that, for the gears to mesh, the raised clearance ring was on the wrong side of the smaller gear - aaaagh! I corrected the mistake and all was well. Also, for the spacing between the gears I used the method mentioned by Kees van Eerken and it worked fine. The final clearance was slightly smaller (from 52.212mm to 51.96mm) so the gears rotate nicely. I also added the suggested .1mm backlash when creating the gears. I must be learning stuff as it's getting easier as I go along. Cheers, John

[@williamsandoval6120]

I'm with you with all the 1-10 videos. Having a blast even thru my frustrations. Thank you!

[@hongleongong662]

Thanks for the effort for making these tutorial, really learn a lot!

[@BrentCWilliams]

Thanks for making these videos. I have already started learning Fusion 360 and some of the stuff you covered is material I've already gone through. But you present things clearly and effectively, and I feel more confident in my knowledge and ability to design stuff as a result. Keep up the great work!

[@patfacunla1687]

Hey Paul! I just want to tell you that your tutorial videos are awesome. after i finished all of your new and epic arduino tutorials i decided to learn fusion 360 and i've learned a lot in these couple of months thanks to you Paul! Take care and sip your coffee :D.

[@annezwart]

Great videos Mr.BoomBoom, exactly what I needed. Very well explained.

[@johnferguson2728]

Nicely done Paul. You are a good teacher. I come from the Aerospace industry where I used the Dassault product called CATIA for many years. Watching you teach the Fusion 360 makes me feel very much at home. Thank you!

[@oddplanetstudios6172]

Another excellent video. Yes, we are still watching! Thanks.

[@fuzzywun]

Thank you very much for creating this series of lessons. CAD had really defeated me for all the reasons you have stated, but now I am beginning to understand it.

[@markgraves2216]

I enjoy all your videos and look forward to the gear box and a future combined project with electronics. Sounds like loads of fun!

[@MrJuuddss]

Paul, again i would like to thank you and your teaching methods, like with the arduino i had no idea how to use or achieve anything until you took the time to explain methodically how things work, well Fusion 360 was kicking my butt for a long time until i started to complete this course you have put together and now not only is fusion dancing to my tune its even asking me to create a tune for it to dance to lol you are amazing at what you do and i enjoy every lesson you publish i love to learn and when you enjoy the subject that you are trying to learn it makes it an easier progress and you make any lesson enjoyable. Keep up the great work you are such an inspiration.

[@robrobinson6706]

Im really liking the fusion 360 lessons Paul. Thank you.

[@raysoftproductions4414]

Just finished printing my Herringbone gears, they fit well thanks to you Paul.....its really a satifying feeling...wish i could comment with a photo

[@roo375]

Your videos are absolutely fantastic!

[@TheKverbeeck]

Gears are so cool ;-). Another great video Paul, i enjoy these very much, thx a lot.

[@MrSSIRON]

Really appreciate all you effort paul

[@Konstantin-qk6hv]

Amazing lesson! Thanks!

[@jaycee7899]

Thank you Paul. I was on the verge of tossing in the tower when I spotted your lesson #1. Glad to say that your patience and awesome teaching style has me hooked on learning more without the use of headache remedy. I'm now on lesson #10 and I'm finally getting to the FUN part of Fusion 360. Much appreciated sir!

[@paulmcwhorter]

Thanks for the kind words!

[@Sir_N8]

These videos are great. Can't wait for the next ones. A mash up of the electronics with the printing sounds exciting as well.

[@paulmcwhorter]

I have a project in mind, but just need to find the time.

[@keesvaneekeren7293]

Caution. The distance between the axes is a calculation with false dimensions. Use the pitch diameters of the 2 gears en divide that by 2 (from the same tabel). The pitch circle is a kind of center line of a gear. A total backlash of 0.1 mm is ok and do not ad that 1 mm that he uses. With his calculation without that 1 mm it can never be assembled The distance between the top from the one teeth to the bottom of that from the other gear is 1/9 of the total teed height. So the distance is 1 part above the pitch circul and 1 1/4 part below the pitchcircle. He was Lucky that it worked. With a pitch of 5 it can not be assembled and a pitch of 1 is a rattling assemble with that 1mm. Hope this helps you.

[@chuckbailey7200]

So are you saying that the distance the posts should be apart is the pitch radius (PD/2) of the big gear PLUS the pitch radius of the small gear? Period?

[@BPerry-vz8dw]

@@chuckbailey7200 Yes. The backlash provides the tolerance needed. The number of teeth (N) equals the Pitch Diameter (Dp) times the Diameteric Pitch (P). Diametric Pitch (P) is estimated by dividing the Outer Diameter (Do) into the number of teeth (N) plus two. So... Dp = N / P and P ≈ (N+2) / Do thus Dp ≈ N * Do / (N+2) And that's how you figure out the pitch diameter.

[@aryaanand759]

i still don't fully understand it can you suggest some tutorials on gears??

[@lordstelanthin]

Thank-you! This helped me get some gears I'm making work perfectly!

[@pointer333]

Curious, though, do you know how to add the backlash after the gear has been generated? Also, not trying to be rude, but as someone who is clearly concerned with truth, you may want to check out 33:50 ish, where he assembles the working gears and demonstrates how well they work.

[@jaredgray7872]

Thanks for the instruction!

[@tomdrought5662]

Thank you sir. Another great video!!!

[@guye7763]

Excellent! We are making progress here.....boom! indeed. Thanks!

[@WildHunter7]

I'm working my through this series. I'm planning a project that me and my 13 year old son can build together. Can't wait to see your project!

[@robertmartinez8133]

Keep up the great work Paul. I enjoy watching your videos. Looking forward to seeing the project using Fusion 360, 3D printing and Arduino. Should be AWESOME!

[@paulmcwhorter]

Yep, really want to put something like that together . . . just need the time. I teach 7 different high school classes each day, so finding time is the challenge.

[@Walt1119]

Another great lesson Paul!! Somehow I got the small gear bellow the plane 1/2 way!! Now I'll go searching on how I can move it to it's proper position!!! Thanks so much for all your work creating these fabulous lessons!!!! (my old brain is sweatin'...)

[@jim.c6780]

great tutorial very helpful thank you very much Paul. printed one of your knurled bolt and nut from the earlier tutorial video you had made printed out very nicely fits perfectly thanks for the videos very appreciated. keep them coming

[@paulmcwhorter]

Something very soothing about playing with the knurled nut/bolt. Had a student make a really big one, and it turned out great.

[@konstantinossarris758]

Very nice tutorials.!!!!!

[@danljohnston]

Hey Paul, in reference to turning sketch off after extrude, 31:22. Check under preferences, design, last check box, uncheck to leave sketch on after a feature creation. Thanks for the videos.

[@paulmcwhorter]

Good suggestion, thanks.

[@littletoyfactory117]

Just AWESOME, I really appreciate your teaching method. I started Yesterday and it has just been so incredibly helpful. I tried Lars back in the spring of last year and found it just so frustrating, He is a good instructor but his approach was different than what I am used to. Yours ties in very well with me having to think 3d and work 2d as most of my CNC designs were 2d that became 3d products. I am someone who tends to hit something full throttle, If I had a Ferrari I would want to see what top gear was like even before looking at the dash. Really repeating the crucial fundamental steps have helped me drive those into my process for when I start designing my own projects.

[@paulmcwhorter]

Lars is a good teacher. He is just so smart and talented, he has trouble putting himself in the position of a total novice. I struggled to learn fusion360, so can relate to all the people not as talented as Lars. That is the great thing about youtube. You can find an instructor that matches your style.

[@chuckpickering6040]

Another great lesson. Please keep them coming! A project suggestion: a speed reduction gear box, such as for a small lathe to slow the headstock down while increasing torque, or maybe a Arduino based stepper driven indexing spindle for dividing.

[@craigtromborg6446]

Great step by step explanations without assuming prior knowledge. Explaining each action in keystrokes is valuable to me. Repetition of the steps in other operations or projects is not tedious but reinforcing.Following along rather than viewing really helps cement my learning. I've enjoyed the variety of tasks/projects. Keep it up!

[@paulmcwhorter]

Glad to hear you are learning. I figured there are lots of guys out there teaching fast, but I need more detail and a more moderate pace to learn. Hope you keep enjoying the lessons.

[@KenKeiscome]

I absolutely agree with you Paul. I have tried some of the others teaching Fusion 360 and just got more frustrated. Then, I found you and my knowledge is increasing faster than I thought possible. When I finish your last video I plan to go back over the videos again. I am striving for not having to use the pause button, rewind, and replay. Then I know I have retained the information. Your speed is perfect for me. Keep up the good work. I for one really appreciate and understand all the effort and time you put into each video.

[@ntptorres]

GREAT... VERY PRECISE AND CLEAR...

[@jon52772]

I would like to say thank you very much for such great videos!! I have made it through 10 of them so far and have learned alot and am confident enough now to be able to do some things i have been wanting to do for a while... i have used sketchup for about a year and have tried f360 about 4 times and always said nope not for me...well now im good to go i think... alot more to learn, going to watch your sketchup series after i get done with this as i wonder how much more i can do in it compared to f360... tyvm for everything....

[@philnewman1110]

Great video Paul, I didn’t think that would fit unless both gears were positioned on the spigots at the same time? Superb accuracy when making gears in this style.

[@aceseights1739]

Paul that was great

[@KenKeiscome]

Another highly informative video. I really look forward to starting the next lesson, but feel sad that the end may be insight. At least for now. Keep up the good work and rest assured when you post something new, I will be there watching.

[@denyssato]

Thank you Mr Paul!

[@HootBuilds]

Your tutorials are the greatest. I always learn something and even though software versions tend to evolve, the name of the tools do not really change although the locations do. One thing about gears and center to center distance. We can use the pitch diameters. "Center Distance (dc) is the distance between the shafts of the gear and the pinion; its value is: dc = (D + d) / 2, where “D” corresponds to the pitch diameter of the gear and “d” to the pitch diameter of the pinion"

[@nwalkeruk]

fantastic tutorial set, quick trick iv found if caught in rotate mode (free orbit) mode is hold middle mouse button and move then release, also when working out the center to center distances you can actually enter the measurement as an expression ed (dia1/2)+(dia2/2)+(tolerance) or in case of radius (rad1+rad2+tolerance) also using custom parameters makes it easier when manually calculating the involute instead of using plugins

[@Dr_Evil_Prime]

Hi Paul, thank you for a great lesson and series. I've been following your lessons for many years, I genuinely wished I had you as a teacher at school, you're very inspiring. As you mentioned, a combination of projects would be fantastic fun - Perhaps some simple mechatronics projects? Fusion 360 with Arduino.

[@caonclaude]

Hello Paul, I'll survive .Last month I started has to build a milling. I use Raspberry Pi2 with Universal G-Code Sender and an Arduino Uno with GRBL as controller. At the same time I learn Fusion360 . Thank you for your time and your passion. I will try to pass on this passion to my little children.

[@johnrita]

Yes Paul just started watching.. and I'm making your projects... Of course you made this video with an much much older ver of Fusion 360.. but all is good. thanks

[@paulmcwhorter]

Fantastic!

[@patrikm8389]

Great! Love your videos

[@paulmcwhorter]

So glad!

[@Country_Bubba]

We are still hanging in there and each week anticipate what you have in store for us this week. First things first, maybe the student can help the teacher. You indicate a desire for sketches to remain on the screen after the completion of the body. Well I think what your looking for is the setting in preferences. Take a look under the “General”> “Design” and near the bottom is a checkbox for “Auto hide sketch on feature creation”. Un-check the box and your sketch remains! I think that is what your looking for?? Yes, your lessons are very helpful and I have completed my first assembly model for an upcoming project that I have. Basically it is an electric actuator with an element that slides in and out of it. It also has a “yoke” type mount on the base end to allow rotational movement around a pin. Couldn’t have done it without your most excellent teaching skills and going slow enough so I can follow along and understand each step! Once again, Thank You for this series. Art

[@paulmcwhorter]

Thanks for the tip!

[@raymondfinch6572]

Still here learning thanks to you Great Teacher Thanks

[@paulmcwhorter]

Appreciate the kind words

[@Allsource-inc]

I had to take a 3 week break due to working. I hated taking the break from your course, but got to make a living, lol. The break caused me to have to back track and just finished lesson 6. I went over lesson 6 several times to get a good hold on offsets and planes. I'll be caught up soon. Thanks sir for all your hard work!

[@paulmcwhorter]

OK, well welcome back!

[@DRosend44]

Another great video! This is really helping me get off the ground on Fusion 360. I've had a number of false starts. Don't get to play with this in my "day job" (Gotta pay the bills!), but I'm using this to understand 360 and give myself a basis for income in my upcoming retirement, plus I'm just plain curious. My emphasis will be to make balsa model aircraft for sale as kits. Still need more info on 3D modelling for creating precise stringers, etc. Hoping that this will come later in the course. Stopped printing out every gear set - I'll run out of room. I take your word for it. They fit great. Great Job! Yes, we are looking at your videos! I'm recommending them to my friends. Don R.

[@trevorrussell9180]

Great learning tool. I like the pace and that you do not cram too much into one video. You asked for suggestions for other topics. Maybe how to draw tapered or conical bodies like a cone frustum or a spinning top. Maybe how to use splines to create complex surfaces or copying a photograph to make it a printable drawing

[@Allsource-inc]

I agree. Although the gears are really super cool, I was also wanting to learn how to draw tapered or conical bodies.

[@garywalker6036]

I agree, if you could do conical shapes, splined shafts and internal splines in gears, that would be fantastic! You could even start off with, "by popular demand"!

[@marioschmit12]

Thanks for this vid🙂

[@ernestasvaikasas6528]

Thank you, still watching in 2020

[@TonoNamnum]

This can be very powerful if combined with the Arduino dc motor tutorials you also made. In my case my motor does not have enough torque. But thanks to this video I will have enough torque. Thanks Paul.

[@perjohnsen5048]

Enjoying the show and very grateful! I can imagine how much time has gone into this. I drew the gears and the platform, but when finished I realized that my objects were all in different levels in the Z plane. I guess I must have messed up with where to put the plane when creating new sketches. Now wondering how to get the gears down on the ground.

[@Just_An_Idea_For_Consideration]

Great lessons! I would be interested in knowing what software you are using to show yourself with the background being your computer - and how you go from larger to smaller in the corner - I like that effect

[@stevewilliams1054]

Thanks Paul inspiring makes complete sense. Have been printing out the models on my new Prusa I3 MK2 and they seem fine. The nut and bolt were a bit tight but work loosened. For the box I used two equal length pins that met, just short, in the middle. My goal using Fusion 360 is to design and 3D printing the parts for a small humanoid robot using an Arduino for the microprocessor. If I could design and make my own gearboxes/motor combinations that would be fantastic, initially it will have to be RC Servos. Steve UK

[@paulmcwhorter]

Sounds like an interesting project, keep us posted.

[@lawrencedeans1433]

Thanks again that's ten I've watched so you must be doing something right :)

[@garywalker6036]

Well sir, I have just spent half an hour trying to log into KZbin, just so that I could leave you a comment. Something I would never have bothered with, had I not had the benefit of your video's. I am 58 and just bought a Prusa mk3 kit because I need to print some plastic parts, so I also needed to learn how to use a cad program. This my friend (and I say that with all sincerity) is where you come in. My son pointed me at fusion 360, which seemed a nightmare, however having tried a few other tutorials and just on the point of giving up, I found you! It was a scene, that could be likened to the three wise men turning up at the stable and finding a donkey, (sorry I meant Jesus)! All jokes aside, thank you very much. I am on lesson 10 and am captivated, you're probably thinking this guy needs to get out more, but how can I with the rest of your video's to watch! Ok enough, you get the picture, I'm grateful. I think that you pitched it just right for me, a complete novice, to the point where by lesson 6, I end up telling you to take the rotate off before you forget it! I wish you'd been my maths teacher here in England when I was a kid, I might have learnt something! Best wishes, gotta go, got number 11 to watch! Regards Gary

[@jamescullins2709]

Good job

[@barrakka]

Hi Paul, I have been following your tutorials on KZbin and I suppose that it is a year since you’ve made these videos. They are simply the best I have ever seen. One question for you. Some of the features that you show, such as the helical gears, are not part of the “normal “ Fusion package. I have found the apps on the internet and have downloaded the helical gears, but how do you get them too work inside Fusion 360. I would greatly appreciate an answer from you. Thanks

[@jamesjones8405]

These have been very interesting and because of the repetition It is starting to stick in my head. I am a gunsmith but I make tooling for milling and lathes.

[@gregcasey1535]

Mr McWorter and other people, I like the style of presentation and it answered many questions of the motivation and usage of the AutoDesk Fusion 360 CAD tool. Does anyone know if such a series has been done on CAM area. I do CNC woodworking and use VCARVE, but it is rather simplistic, But my experience with FUSON 360 CAM, it is overwhelming. I would love to see a down- basic for the CAM area of FUSION 360 - Thanks

[@phakalanep7241]

FYI a double helical gear (hearing bone gear) was designed by Citroen and is still used as a decal on all of their products

[@hanspijpers2100]

for every body who is watching this great tutorial: there is a very simple shortcut for most of the drawing that Paul does, for instance if you are in sketch mode you want a circle of say a dimension of 47.569. you type the shortcut "C" click the start (center) point of the circle let go of the mouse button, move the mouse slightly away and DON'T click, but type directly the dimension (47.569) and the return key twice. One other great shortcut : if you want a "construction line" or construction square simply type the X key and then the L key on your keyboard and draw that line, or type X R for a construction rectangle click the start point and draw the mouse a little bit away and there appears the blue input message again type the first dimension and the tab key and then the second dimension. There is a small (but) , the stays active , to inactivate it simply type the x key again It also shows the status in the " sketch palette" Paul this is not criticism I do love the ex-tense of your tutorial I only hope the viewers and maybe yourself can benefit It take some time to get used to it but believe me it works better (for me any way) kind regards Hans

[@tosselton291]

Well I am watching lol here is a question though would it be better using the pitch circle diameter for the axis? With the 4th axis gears are in my future and as far as arduino I have not gone further than blink.

[@jeffbedell3809]

I designed a gear, that was to be 20mm in dia. When I saved as a .stl and opened in Slic3r it nearly doubled in size I had to reduce to 48%; any ideas why? Love your videos. Making Fusion 360 so much easier to work in.

[@eternalsolutions2986]

Can we put helical or herringbone gears on a wall and have the gear move up and down the gear threaded wall as it spins?

[@rubencal6577]

Thank you

[@silentbob6668]

Hello Mr.McWhorter, you can rotate with - shift & middle Mouse Button.

[@charlotteswift]

Loved this lesson! I really like the idea of combining 3D printing and the raspberry pi. I've noticed from the comments that most of the people watching seem to be male and therefore interested in things like 'a speed reduction gear box, such as for a small lathe to slow the headstock down while increasing torque' WHAT?????????? I used to play a board game called Mouse Trap when I was a child. At the start of the game you assemble a Heath Robinson contraption out of plastic parts and then use it to catch another player's mouse. You start by turning the crank, that rotates the gears, that push the lever, that swings the boot, that kicks the bucket, that sends the ball down the stairs and into the gutter, that leads to the rod that releases a second ball, that falls through the bathtub and onto the springboard, that catapults the diver into the washtub, that causes the cage to fall and, hopefully, capture the mouse. Just imagine how much fun it would be to design your own machine and produce it on a 3D printer! You could use helical gears (straight or at right angles), rack and pinion gears, an Archimedes Screw with tiny ball bearings instead of water, something like a mill wheel driven by a stream of tiny ball bearings that could raise a bigger object... The possibilities are limitless. Adding ridiculous elements like the boot, bathtub and springboard would make it much more fun. Connect up a Raspberry Pi to it and WOW! I bet that your high school students would love it (and be able to think up lots of other components). I would love to hear some of their ideas. Life shouldn't always be too serious! I'm also planning various raspberry pi projects:- Using a rpi as a VPN server in the UK (I live in France) so that I can access BBC iPlayer. The chaps at the BBC know the IP addresses of many commercial VPN providers and block them. Making wireless speakers by connecting them to a rpi and then using my iPad and Airplay to play music while in the bath. (can you tell I'm a girl?) Connecting a rpi to the TV and then using my iPad and Airplay to be like an Apple TV. Using Alexa on a rpi to be like an Amazon Echo. Perhaps also try Google Assistant and Siri. Maybe they could get into an argument. Motion triggered wildlife (or burglar) camera. If anyone is still reading this.... I agree with you, Paul, when you say that it goes against the grain to use the keyboard and the mouse at the same time to rotate a design in Fusion 360 but I persevered with it and it's SO much easier.

[@paulmcwhorter]

Might be interesting to make a Rube Goldberg type machine. I remember the old mousetrap games.

[@charlotteswift]

Ah! My Heath Robinson is your Rube Goldberg

[@rukidding7588]

@@charlotteswift Yes. And the Danish Petersen. To me at least, the main difference between Robinson & Goldberg is that Goldberg actually built a number of his contraptions. AFAIK, Robinson did not. Actually building such contraptions puts extra pressure on the designer. You can't get away with impossible geometries, a la Escher. In the end, both men were very creative, and I wouldn't be at all surprised if Goldberg drew inspiration from Robinson.

[@sandeepkumar-by8gs]

thanks a lot

[@Eugensdiet]

Paul, helical gears are not stronger but they are smoother and backlash is less prevalent. Visualize that one gear tooth is covering the whole range of transition. At any point in rotation there is one part that is engaging and at another point it disengaging and everywhere else it is in a different degree of engagement and this is what makes them smoother. .

[@DennisMurphey]

Worm gears and specific gear reduction requirements I have a real project to take an electric motor and convert a wheel that triggers 4 pulls per output shaft rotation. Is there worm templates in the library I must go look and see. Wow this opens so many doors for custom operations of my model trains. I just need a better 3D printer to make precision smaller parts. THANK YOU Paul, wonderful job. This is why we want to stay engineers in retirement, its fun to build stuff. I want to do as much as can until I can't . D

[@DennisMurphey]

Made a worm But i need the threads on a lofted surface is that even possible?

[@apotter8888]

I am working on an "invention", and when I call potential licensees, they want a CAD file. I realize I need to learn CAD. My invention does not have gears, but I need to learn and understand how it all works. Thank you for all your patience and attention to detail.

Yes, I had a Gaggia Super Automatic one touch cappuccino maker, but alas, it has gone out and can not be fixed, so I am down to drinking instant. I am looking for another super automatic, but have not bought a replacement one yet.

@@paulmcwhorter I have a Gaggia and have fixed it a few times lol. Thanks for the videos. I thought I could never get off my addiction to tinkercad. The new version of fusion is a little different so I had to figure out some things . The one thing that bothers me is that it won't default to your axis setup even when I fix it, for every new drawing

Another great video. A project suggestion with a gearbox. What about a garden windmill driving a gearbox linked to a generator (dc motor) to light some decoative LEDs. I tried doing this without the gearbox but couldnt get the rpm on the generator.

If you click on your name in the upper right corner, you can go to preferences and then to design. In design, you can uncheck “turn off sketch after a feature”. This will leave your sketch turned on .

No matter what I do, I cannot get the gears to move if I later adjust the construction line that we're using to distance to components.

HI again Paul, Maybe joints is the next direction to go? Thanks for the lessons.

One lesson in this series left to release . . . then I have to find more time to make more.
