MACHINE SHOP TIPS

[@dirtyharry793]

Forget about the Trolls, they are not your friends and have nothing to offer! You have inspired so many of us out here! I personally have learned so much from your teachings, that I went out and bought an old Logan 10" and a Chinaman Mill/Drill (don't have the space and money for a Bridgeport, but I wish I had) and am able now to turn and mill some decent pieces thanks to you. You can't learn everything out of books. Seeing how to do it on your videos is the key!!! We all enjoy them!

[@andrewthick185]

Dear Sir, I am an ex machinist returning to a home workshop practice and you are a touchstone amongst us who enjoy this kind of work. Have no fear of detractors. They not what they do or say.

[@mrpete222]

👍👍

[@mikestevens8046]

Mr Pete, I spent most of the day fiddling around with making an eccentric and never did nail it so I did a youtube search of your vids on the subject. How simple you made it is really pretty awesome. Thanks for all you share with us newer folks and screw the trolls. They are a wart on societies butt.

[@mrpete222]

👍👍

[@kgee2111]

Not only are you a good machinist, you are a good teacher too! Thanks again.

[@mrpete222]

Thanks

[@rlunderhill]

Good information. I'm a retired machinist 45 years in the trenches. It's nice to watch lathes and Bridgeport's again. Thanks.

[@rprichard8452]

I need to say this as an inspiration to you! I started machining in 1973. I’ve even taught engineers what certain machines can and can’t do for obvious reasons, and I can’t remember how many trainees I have taught. But darn it, I like watching you anyway! As any professional machinist knows, you’re always learning something new almost every day. I’ve learned a few neat things from you, so thanks for your insight. Keep it up my friend. 😉

[@mrpete222]

Thank you very much that makes me feel good

[@kalleklp7291]

I'm at the beginning of making a flame licker engine. As I zapped through several videos for inspiring things, I came by your video. Knowing from other videos you've made that you are a very talented craftsman I simply had to see how you fabricate an eccentric. Thanks for sharing your knowledge and wisdom with us. I subscribed to your channel long time ago as there is always some useful tips and tricks for me to learn.

[@jimmilne19]

This one provides a valued contribution to the ever expanding library of educational materials from the greatly honored and highly esteemed Tubalcain. Thank you again.

[@davewhitegas2415]

Great video. I was once thinking all the conventional machinists were becoming a thing of the past due to the CNC replacement operations. Lots of the younger fellas think CNC is the only way. I have made eccentrics and used the packing method, now I have a few more ideas. Thank you and God bless.

[@bulletproofpepper2]

Thanks, Mr Pete. my little hobby lathe and i are getting along better. very happy with the videos you make. i had bought books to learn from years ago but couldn't understand them, now i'm re-reading them and it's all falling into place. i was able to make some parts and bushings for my father to fix an old tractor. he mailed me the bronze blanks with a dimension sketch, a note, and some stamps to send them back. i'm not going to the moon, i'm fixing tractors! thanks to you.

[@petercunningham4000]

Thank You for another great presentation. I have the tools that I "inherited" when I bought this rural property here in country New South Wales in Australia. I do want to make model steam engines, which is why I asked the owner to leave me all the machines, - at a reasonable price. You are teaching me how to use the various machines and, just as important, all the various measuring tools,-micrometers, etc. SoI wanted to let you know that I really appreciate the way you take the time to explain everything clearly and at a pace that people like me can learn. The man I bought the property off was an engineer, just like yourself, and he used to say, that when he started out in his trade, if you wanted a special tool you had to make it, as there was no store bought tools in those days.( he was in his mid-70s when he sold up and moved back to the city area). as he became too ill, and failing eyesight, caused him to sell this rural property. He could make anything in his machine shop, but he was not a good teacher,-or I was not a good pupil, more like. I think it is a special gift that enables someone to teach as well as being able to do something. People for miles around used to bring things to him to be repaired, - especially their guns for new firing pins or to repair the sears,(I don't know if I have got that right) but, he used to talk about people not respecting a precision piece of engineering. Anyway, until now, I did not have the confidence to use the lathe or milling machine. So a big Thank You from me for all your work you do in putting together all these videos. Best wishes from, Peter Cunningham. Australia.

[@Speeddemon77710]

I always look forward to your videos. I am a student in mechanical engineering and had the opportunity to take a machine shop class. The class was so inspiring for me but lacked the teaching quality and encouragement it deserved. So I set out to the internet for some help. I cant even tell you how excited and happy I was that I found your channel. Many sleepless nights have happen cause I couldnt stop watching. I have almost watched every single one of your videos over the course of a few months. I just wanted to say on behalf of others in situations similar to mine thank you for fueling our inspiration with your teaching. -Kevin

[@joebarker9462]

Wish i had you as a teacher back when i took shop in high school you have a very straight forward way of instructing and watching your videos is a peaceful escape for me keep the videos coming

[@mrpete222]

Thank you very much, I'm glad you like the videos

[@MR6.5]

Always a pleasure to view your wonderful videos. When I run into something in the machine shop I have not done before I come to your videos for instruction and they never fail to educate me!

[@mrpete222]

Thanks

[@peteferguson7024]

Great video! The funny thing about comments is that we don't own what other people say, they own their words, they do not and cannot define us..... we are, who WE are. Thanks so much for the opportunity to learn and grow along with you.

[@75Bird455]

Ignore the trolls indeed - They exist only to tear people down. Your video's are a great learning tool for people like me. I've got a 1700 lb. South Bend 13" in my garage right now because you made me believe that I could do the things you do. That has to be worth something!

[@mrpete222]

WOW--that's gratifying for me and a great new interest for you.

[@frankwolfe1524]

Thank you Mr Pete... I was kind of at wits end as to how I would make the eccentrics for my next project without having a 4 jaw chuck for my lathe... The formula Packing method is a life saver...Being retired and on a fixed income I don't have the immediate reources to buy the 4 jaw chuck...I wouldn't lose any sleep over negative comments... Anyone with a grain sense can figure out everything you so accurately describe easily...Even my wife likes your educational videos... I may be an old dog but I am still learning...Keep up the great work and take care...Canada loves your videos...Frank

[@thomaslizon2594]

Dear Professor Tubalcain, your green fabric is great, looks like a poker table with your hands playing with those nice excentric coins..! Thanks for the passion you put in sharing your passion! Best Tom, Paris, France

[@JDFARM]

I am not a machinist and probably never will be. I am not qualified to critique this mans work but what I can say is I have just finishing video #160. I am using this as a method of learning how to use some tools I have recently purchased. What I am qualified to say about Tubalcain is this. A man that would spend this much time sharing his life time of knowledge with all of us is bound to be a special kind of person. Now he might be picking up a dollar some where in this but look at all the free wisdom he is raining down on us. His tools are the things he has accumulated down through the years but think of the lighting and camera equipment he has bought, they are dedicated to the production of his videos. Price some of this quality equipment. It is not cheap. I have an appreciation of skilled people. I have spent a life time of dealing with 20 year old that are not qualified to use a lawns mower, 30 year old collage grads that cant fill out a job app and sign there names due to a double standard where everyone has to pass and graduate just so they can feel good. I consider myself to be a knowledge sponge. I soak up everything. No information is too trivial. The only problem I have with Tubalcain is he lives too far away. I think he would make a great neighbor and friend. I hope to have the honor of meeting him some day. I am pretty sure we would have many deep conversations. NOW FOR ALL THE HATERS. Relax, take a deep breath and have happy thoughts. Don't be jealous of others. You are what you are and with time and practices you will get your GED and maybe someday you will own that lawn company, or at least have your own mower. One thing for sure, if smoking pot and spreading hate and discontent are your only goals that is about all you will ever have in life. Go ahead and hide behind that keyboard. You are not qualified to shine a light for Tubalcain to walk by.

[@mrpete222]

Thank you very much for a kind and encouraging comment. I am humbled by it--I sent it to my daughter to read. I don't get a lot of bad comments, but some are hurtful--and I never respond to the trolls. keep watching, lyle

[@JDFARM]

Mr. Pete, we are close to the same age and most younger people done understand the value of knowledge and education. I never went farther than high school but have a life time of world experiences. We have that in common. I am sure that you have a college education. Schooling is important but there are no substitutes for experience and at our ages we understand. All tho we have never met I consider you a friend and you would be welcome in my home anytime. I hope we meet someday, John Dickson P.S. Stay in touch. [e-mail]

[@mrpete222]

Yes-- yes, practical experience. I learned more about teaching in 10 weeks of student teaching than the whole rest of my college classes. Glad to meet you. lyle

[@JDFARM]

I am on number 165 and looking forward to the rest. You are doing a great job and mush thanks.

[@gwood64]

Mr Pete I sincerely thank you for these videos. I am 51 and bought a 7x12 aisian lathe in December 2014 so I am very new to this. Started watching your videos even before I bought it. I now also have a mini mill. Today I refered to your video on making eccentrics to figure the shim needed in my 3 jaw for the offset I desired on a little project. Pretty scarey at first but it is going well so far. I also just got the drawings for your spool valve engine and hope to start on one soon.

[@mrpete222]

Thanks for watching & good luck with that engine

[@Guds777]

Mr Pete, it is normal to take negative critic personally, it means you care. Thank you for your videos, it is so much enjoyable....

[@icondonnied]

All your videos absolutely amaze me. I have never used a lathe in any capacity (I like to play with electricity), but these videos have inspired me to add a small lathe to my workshop and to learn how to use it. I just found your channel recently, but will be watching EVERY video eventually..... Thanks for the informative videos!

[@mrpete222]

Thanks--yes watch them all.

[@rljzathras]

When I made my tail stock cam lock, I used your 3rd method, but checked the eccentricity with my dial indicator before cutting the lobe. At the time I was unaware of the calculations, and arrived at the "1.5" by trial and error! Another win for the University of Hard Knocks :-)

[@77.88.]

I have to cut an internal eccentric that will move balls in and out through a hole drilled through an inner revolving shaft and did not have a clue how to tackle the task, but as usual YOU have taught me something useful, how kind you are to freely pass on your knowledge. Thanks so much

[@mrpete222]

Glad I helped

[@sloan0909]

Thanks for another great video mr pete, I am 27 years old I have a small shop with a mini lathe and mill etc, I love watching every one of ur videos, u have taught me a load of techniques and tips, there is a load of great talented guys on KZbin but you are by far my personal favourite keep up the fantastic work and especially the look what I got at the sale videos, I would also love to see a more detailed view around ur basement shop and garage etc, :)))))) thanks again, Steve from Scotland

[@mrpete222]

Thanks for watching. I'd like to show more of my shop--but i'm kind of ashamed.

[@chipwright6193]

mrpete222 Don't feel ashamed! There are many of us out there whose shop looks "Worked In". I don't imagine that there are many folks out there whose shop looks like a picture in a magazine. Thank you for the great videos.

[@sloan0909]

ashamed? i say a place for everything and everything in its place, it's just that u do literally have EVERYTHING :-), and i would love to see it.

[@jameswhite6519]

Hi don’t let the trolls get you down. I viewed your video, the part about the three jaw chuck method twice. Went out to the shop set up my shiny new taig lathe the way you demonstrated and half an hour later with a nice new eccentric on my bench I am writing you this thankyou note. Please keep making your videos myself and many others will thank you!

[@gohuskies583]

Yes the green background is a great choice. Pleasing to look at and gives a good background for clarity. A wooden bench top would not give you that. Thanks for the extra effort to make your videos top notch!

[@mrpete222]

+gohuskies583 Thanks for watching

[@Daledavispratt]

The green backdrop is my favorite, and they do make it much easier to see what you are showing us. Thanks!

[@aj9270]

Thank you once again Mr. Pete for another enjoyable and educational video . I really appreciate your time in making them !

[@Mr45shooter]

I enjoy all your videos keep them comming. You are doing a great job passing on knowledge. Thank you.

[@kenzpenz]

Thank you so very much. I am building a model engine and it requires my turning an eccentric. I was agonizing over how I was going to do it. Well this comes in the knick of time and I actually look forward to making one. Again, thank you very much....Ken

[@mrpete222]

Glad I helped-Thanks for watching.

[@JoeGassen]

As usual, terrific video! You have inspired many including myself. I just drove 650 miles to purchase my first lathe. An Atlas 12" with lots of tooling!

[@mrpete222]

+Joe Gassen and well worth the drive

[@msyoung76cj7]

Definitely don't worry about the trolls! You have over 44,000 subscribers which means they are here for your knowledge. That speaks very loudly for your positive popularity! Keep up the good work! I think the green backdrop helps the camera focus better on closeups instead of wandering into a blurr

[@kerrywil1]

It takes a craftman to build something but a jerk to tear it down. Thanks for the effort on the video's

[@AstraWerke]

Your video is right on time - I am currently building a beam-type steam engine, and just faced the problem on making the eccentric - thanks alot!!!

[@WideVisionMetalFab]

The green back drop is nice! It makes your videos look professional. Thanks for showing these methods, I always learn from you! :)

[@volcom7114]

Me Pete I hope your around making these videos for many many more years to come I think I can speak for many other and say we love you! Your a great teacher and you go into detail about how this are made or done.. Great job!! I would like to see you make a video about how to make a collet chuck for your Atlas or another lathe.. I would like to make one but I would like to see how a true machinist would approach this... Thanks much as always! Dennis

[@mikedigirolamo3991]

Hi Pete, As far as the "Trolls" goes.. use duck-feathers and shine 'em on -- you've been teaching all your life and know what you're talking about. Keep up these wonderful videos. There are far more of us who appreciate your knowledge than the rest! Mike

[@RRINTHESHOP]

You are great. Your videos are very helpful and great to watch. Thanks again.

[@Karebear9001]

Some people are never happy. They remember being 16 because they still act the same and haven't grown up one bit! I finally have access to a lathe and mill at a community workspace (Durham NC, Splat Space) and plan on putting everything you've taught us to use!

[@barleyhouse]

Informative and entertaining video - as always! I always look forward to your next video and thank you for all the pleasure your videos have given me and many others over time. Can there be anything more satisfying and therapeutic as watching a skilled machinist making swarf? All the Best, Neville

[@quasibrain2319]

Thanks for another excellent video. I subscribed to your channel several years ago. Your presentation and commentary is the best.

[@Shackelchevy77]

been watching you for a couple of years now and have learned sooooooooooooo much THANK YOU

[@donaldnaymon3270]

Great work Mr Pete. Thank you for sharing all the different methods.

[@mrpete222]

👍

[@lacetmiel]

Thank you for your interesting and informative videos. I have puzzled for a long time over how to make eccentrics. Really enjoy and appreciate your posts.

[@mrpete222]

👍

[@GlennMartinez]

I just received my four jaw chuck and was dreading the learning curve to use it. Now I am excited to go try the TWO KNOB method....I really appreciate have an option of three different ways....Thanks again...

[@DSCKy]

The 4- jaw is easy and pretty quick to indicate in once you get the hang of it. I usually use 2 keys until it's close and then work the highs. If you haven't seen ABOM79 work a 4-jaw... you should.

[@mrpete222]

DSCKy YES

[@pgoessnitzer]

Thank you for sharing your knowledge and presenting this video and other videos. I used the last version, shimming the workpiece in a 3 jaw chuck a couple times, but I really like the 2nd method you show with creating an offset jig for making multiple parts. Thank you for that tip!

[@mrpete222]

👍

[@rcwarship]

Thank you so much for taking the time to make, edit & post your wonderful videos. I really really appreciate you & your ability to explain complex tasks in easy to understand language. Thanks Again & Best Regards, Jon

[@mrpete222]

THANKS for watching

[@jackcostello2478]

Thanks for all the great videos. Love the green cloth - reminds me of my misspent youth in a pool hall. Jack C.

[@ApeShift]

Just FYI, the Ford Modular engines get their name not from the parts interchangeability, but from the plant design. The entire engine plant and tooling can be changed over in a matter of hours to manufacture a different engine type. Love your videos by the way! I have only taken a few machining classes at the local community college, but I always learn something from your videos!

[@mrpete222]

Thanks--very interesting

[@hdoug5]

I'm glad you made that video, I have been wondering how I could offset some work without a 4 jaw chuck. you made it crystal clear, Thank you :)

[@11zekim]

Outstanding, thanks for this tutorial sir! I've used the "packing" method a few times over the years, without thinking it through. At one point, I used feeler gauges to guess the 'rule.' Your vid finally egged me into some proper algebra. The formula is in fact 3/2 (1.5) plus a correction that depends on the ratio of the eccentricity to the work diameter. The error of taking a straight factor of 1.5 is small, so long as the eccentricity is much smaller than the workpiece. The largest eccentricity machinable this way is about 0.58x the work radius (beyond this, the work will drop through the two "unpacked" jaws). At this extreme, the "x1.5" approximation is only off by about 18%. Thanks again for all the learning! Mike

[@TXKurt]

Hi Mr Pete, with the packing method, you could skip the formula by putting the stock into the 3-jaw-chuck with an indicator between two of the jaws. Holding the work against those two jaws, open the chuck until the indicator shows the offset you want. Then measure the gap to the third jaw and find a packing of (or close to) that thickness.

[@mrpete222]

EXCELLENT idea.

[@TXKurt]

mrpete222 Thanks for the video!

[@fall22123]

Awesome video. I really liked the fixture. We use something similar at work but it is made to hold the work at an angle so the complex part can be turned off-center and at an angle.

[@mustang2440]

Always looking forward to your next video; never a disappointment!

[@gizzo123us]

You may think no one wants to hear what your saying on stuff . But it is all good to us. To develop the skills takes years to master. all the help I can get. I thank you for sharing !!

[@pierresgarage2687]

Hi mrpete, Green background is looking good! Good inspiration. This brings me one little suggestion to maximize use of your jig, you make a longitudinal slit that you can tight with a screw, install a backing stopper in the 3/4" diameter. Then put the pre-cutted (Already bored and faced on one side) 3/4" slugs in the jig, tighten it with the side screw, install a preset stopper on the ways with a 1/16 shim, face, remove the shim and cut the eccentric with a parting knife, that should give you the precision required for the purpose. Just a elaboration starting with your idea. You're an inspiring person thanks for your teaching, Pierre

[@mrpete222]

Thanks. Thats a good idea.

[@rekmstsage]

Thank you for this very helpful video, as simple a part as the eccentric is my mind has always had trouble grasping how to design and build these things. This simplifies so much!

[@mrpete222]

+Rek MstSage Thanks for watching

[@steveleatherbarrow5917]

Thank you for all your videos. Always enjoyable and full of interesting and good, no nonsense information

[@MrTrainman109]

The packing method is a awesome ideal I would have never thought of that. Thanks for sharing.

[@rickswazey9472]

Very nice work, Mr. Pete. I've always liked steam engines and the models are fascinating. Keep up the good work. RS

[@rickyretic]

The green backdrop looks great !

[@Leejon57]

You just saved me money on a 4 Jaw, I will use a 3 jaw with packing, Thank You Mr. Pete!

[@mrpete222]

You are welcome

[@johningardia7106]

All right, here we go Lyle, just love that green back material. Just love it. All kidding aside; you do a great job.

[@MrShobar]

Wonderful video (as usual) Mr. Peterson. Nice old Logan lathe, too.

[@litefoot900]

A very well narrated and interesting video, as always, Thank you.

[@jayphilipwilliams]

You could also put the work piece in a three-jaw chuck attached to a rotary table on your milling machine. Center the piece, then offset the table in any direction by the appropriate amount. Then just spin the table one full revolution and you're done! I didn't read through all the comments, so someone may have already suggested this.

[@mrpete222]

+Jay Williams Thanks for watching-good idea

[@aserta]

Awesome vid. Gave me a lot of ideas regarding off-center work. The green back drop makes things better on camera when it comes to details. Mostly because it's not a color you usually see. As for the trolls, nobody cares about them, neither should you.

[@skorkmaz]

Cool. I just received my independant 4 jaw chuck. And I like your two knob method. Thanks for the tips.

[@mrpete222]

👍

[@Litzwire]

Nice one, as inspirational and informative as usual. Green back ground helps detail stand out. Ignore the trolls, negative feedback is worthless. I'm sure your going to need more than a dozen eccentrics to last you out. Keep up the great work.

[@Tatorhead1234]

work people like you do...almost magic

[@rustycalvera977]

well done...I like the nice close shots....good camera work.

[@robertallnutt3717]

Thank you for an other wonderful video, you are a great teacher.

[@k5at]

Thanks for showing the different methods, Great Video. Thanks for sharing.

[@paulduffey7975]

I have not yet turned an eccentric so thank you for the ideas. I was wondering if one might turn the smaller part as a separate piece and attach it to the larger diameter with bolts or silver solder. Would this work on a small model? Also I had noticed the green background and wondered about it as most vids just have a metal or wood table. The color certainly contrasts with the parts. Interesting. Thank you very much.

[@whiskyjacked]

Thanks for the new formula! I collect tricks like that like it's money

[@Opinionator52]

The green material resembles pool table felt, perhaps some didn't want to make that comparison or suggest you would do such a thing... O,

[@MyShopNotes]

Mr Pete, the green is great. And you can use that green in video edits to do overlays. Thanks so much for all your videos. I have learned so much.

[@mrpete222]

+Steve S Thanks for watching

[@yt650]

Love your work. Very good teacher. I can’t remember a statue erected to a critic.

[@mrpete222]

+YT you are wrong, there are statues of critics. Remember the song Statue of a fool!

[@yt650]

mrpete222 No I do not.

[@ShuffleSk8Ter]

One of your better vids Mr Pete!

[@userunavailable3095]

People are getting awfully quick to label someone a troll. Not all critics are trolls. Some folks just want to tear folks down. Others want to help folks improve. Don't worry about those who want to hurt you, but if the criticism is constructive, use it to help you make a clearer video next time. I'm really enjoying your videos. I like to know how things work, and I hate to see older skills die. I'm teaching myself to spin wool right now for that reason, and I spent years learning how to break and drive horses for that reason. Keep up the good work.

[@ApeShift]

Constructive criticism is OK, but worrying about parallax error when measuring an eccentric for a model steam engine is rather pedantic. It's not making 10,000 hp, and it's not putting a man in space. +/- .005 should be more than accurate enough.

[@curtis0432]

This method does work on large scale I used very similar techniques on a 1000lb crankshaft

[@Temuba]

The others here have stated well. Excellent as always and thank you for this priceless information.

[@Ixamxionion8]

That was great ,your a good teacher, this is something I will use but on a smaller scale. Thank you.

[@fabtechamericanmade797]

yea Mr pett just wanted to say I like your back drop your using iv stared useing one my self when I saw what you had going on there I really truley believe that it makes the work show up better with using an back drop me and my boy love the things you do one KZbin keep up the good work he wanted to tell you we are starting to build our first steam engine he's been watching you Channel so he could get some good tips keep up the good work we love your Channel

[@mrpete222]

Did you like the backdrop behind the lathe? Or the green one on the bench. Thanks for commenting. I actually go to a lot of extra effort for that, and you are the first one to ever comment on it. Good luck with the engines. It is a wonderful thing you were doing with your boy

[@princebatswater]

Hi Mr. P. Why is an eccentric used for the valve instead of a crank? Is the geometry different maybe? (The word "locus" comes to mind from when I was taught engineering drawing at school in the early 80s)

[@rljzathras]

I'm thinking the relatively small offset would be a good reason. There would be little room for a shaft + offset pin. In addition it makes the bearing surface much larger and less prone to wear (flogging out the journal)?

[@stephendeakin2714]

The formula method appears to be a great way to do eccentrics, save s all that fiddling about with offsetting four jaw. A nice background like your green one really shows off the object nicely, I think most people will as I did, just have thought it was a bit of cloth you had about you and thus not commented on it. Have a look at Paul Crompton videos to see his take on background cloth.

[@emgeeradian2223]

Great video showing all methods.

[@dennisf876]

You are the best!!! Love all of your videos. Keep 'em going!!!

[@tzkelley]

Another great video! Love the packing trick.

[@larryhawkins8311]

Excellent information, thank you, enjoy all your videos.

[@howardblinder9551]

Hi Pete - I am a retired toolmaker with a small garage/shop. I am enjoying your videos and have watched several over the past couple of weeks. I have made one if the wobbler engines and am working on my second currently. Just finished watching your “Eccentrics” video. I was wondering if you have considered making this on the mill using boring bar as another alternative? I know that you made this video years ago, but was thinking that some of your viewers may not have a lathe in their garage. And the boring bar could actually be setup in drill press in a pinch. Lol. Just thinking outside of the box. Best regards, Howard

[@mrpete222]

Thank you Howard Eric that was a good alternative. Probably would make a good video.

[@FisVii77]

Great video, thanks for your time and efforts truly enjoyable, I shall hope to watch your new videos 20 years from now, perhaps you can show us a 4th method after you've run out of your eccentrics :) Take it easy tubulcain and thanks again for sharing your time and experience. Greatly appreciated.

[@haskapman]

Thank you for another great machining lesson. Do you have any suggests on how I could machine a spiral? Like a thread but with a very steep pitch. For example two threads per inch.

[@mrpete222]

Sorry-have never done that.

[@donotwantahandle1111]

Gee I wish I saw this video when making eccentrics for 7 1/4 in tank loco! I didn't know you could do that with a 3 jaw chuck.

[@MrRingsten]

You bought an two-jaw chuck the other day. It should be perfect for this project? Thanks for all the interesting videos you are making!

[@patrickcraig6032]

Enjoyed the video,Am going to make the vertical engine.This will help.Thanks.

[@mrpete222]

+Patrick Craig Thanks for watching

[@MrMichaeljab]

Love all your videos, Thanks! Was there a reason you changed from your usual Aloris tool post to a lantern style tool post for this job with the exception of the cut off operation? The green back drop is great! Makes things really easy to see.

[@davedigs]

great video as always i read an old model making book that showed turning a crankshaft between centres you had to drill two centre holes on each end wondered if youd ever used that method thanks for sharing Dave from the uk

[@mrpete222]

I think I read the same book years ago.

[@horneygeorgeforge7079]

Very informative! thanks for sharing ! as usual I have learned much form Videos like yours and the others. thanks again Dennis
