Building Prototypes Dan Gelbart part 18 of 18 Design

[@Clickspring]

Thank you Dan, for sharing this excellent series.

[@Heatseeker1]

This series needs more views; you should feature it on your channel, and perhaps send him your camera and audio tips to encourage more!?

[@AdityaMehendale]

@@Heatseeker1 Applied Science (Ben Krasnow) already did; apparently it is not appealing enough for "casual" KZbin-engineers. Myself? ..I have binge-watched all eighteen videos (and the other four too) many many times :)

[@michael-rommel]

I agree! Also a big fan of your channel!

[@freelancergin]

Watched the whole series and it was more enlightening than any lecture I've seen. Thanks for uploading and I hope you make more videos.

[@dgelbart]

Thanks! Gives me motivation to produce more.

[@AndriyPodanenko]

+Dan Gelbart just finished whole series. Impressed. I must to say that the rule about design and 100% functionality works for your videos as well. There is no non functional information in these videos, that is why they are beautiful. Thank you, Dan, a lot. Can't wait for a new videos.

[@adwaugh]

+Dan Gelbart Yes Please! Please also tell me that you have taken on some apprentices - the next generation needs rennaisance men too.

[@artelse]

Please make more video's. As you started out as an electrical engineer and instrument building often involves electronics as well, I would be very much interested in your knowledge on designing hybrid mechanical / electrical instruments. Anyhow, this was already much enlightening, thanks!

[@t76d777f6d]

Hi Dan, I am graduating from a mechanical engineering technology (4 year) program this May. I cannot decide if this was the best way to cap off my education, or if it would have been best to see it at the beginning. Either way I am grateful in ways I cannot communicate. I have learned in my short time on this earth that when learning a new skill there are always hidden gems that greatly accelerate the learning process. Whenever I try to learn a new skill, I always try to seek out these gems, but it's often very difficult. It is usually difficult because the experts seem to believe that understanding is something achieved through many hours of hard work and not through understanding. Your 18 part series is taught only in these perfect hidden gems. Each section was perfectly succinct. I never once felt you spent too much time on a topic, and only a couple of times did I wish for more discussion. You assume the audience has an aptitude for mechanical understanding but you do not assume they have a mechanical education. I think these things result in the best presentation of mechanics and prototyping I have ever seen. I would go so far as to say this may be your published masterpiece. I hope one day you do an 18 part series on electrical topics. A sincere thank you, Luke Pighetti

[@martinda7446]

Wonderful, isn't it. Hope you are doing well in the four years since graduating.

[@pcb1962]

I've watched hundreds of hours of machining, fabrication, and tooling videos on KZbin in the past few years, I thought I'd seen it all. Then I discovered this series and my mind is well and truly blown. I completely agree with what everyone else says below, a truly amazing series and a wonderful presentation style, thank you.

[@ProVrakian]

Thank you so much for making these. This series feels like it has nutritional content.

[@jimmilne19]

This is an amazing series of videos, several of which I have watched multiple times. I would encourage you to make more. Your experience and acquired skills must not be shared with the relatively few fortunate students who have personal contact with you, but with all who thirst after quality education in this field. Your delivery style is delightful and I found it inspiring, motivating and pleasant. I wish I had known of this series before now. I thank you for sharing and repeat my hope that you will produce more for all of us to learn from.

[@alexecheverria]

A sunday afternoon well spent watching all 18 videos. 100% functional! I learned so much I feel light in spirit. Thank you.

[@andrewrobb633]

Hi Dan, Thank you for this series. A pot of gold in a sea of rubbish. Inspiring. Cheers Mate

[@milesingramisgood]

What a great quote to finish a great series of videos. Many thanks Dan

[@thebrokenbone]

Thank you mr Gelbart, this education is completely out of reach for me, but you sharing your work have opened a field which until today was unknown to me. Thank you very much. Please, if it`s not much asking, continue sharing this wonderful world with us. Regards. Peter Penca.

[@plnmech]

I have watched all 18 videos ,some more than once and I have both enjoyed them and learned from them. Thank you for producing them.

[@conankilcoyne5826]

Dan, these videos of yours are golden resources! Thank you so much for sharing your knowledge. You're a great teacher.

[@rippermcguinn]

I have worked in supplier quality for many years, and after viewing this series I'd almost consider these videos to be required viewing for anyone who wants or needs to know not only HOW things are done in manufacturing, but WHY. Fantastic.

[@robindebreuil]

These videos are amazing -- so loaded with practical information that it take many viewings mixed with many hours in the shop to fully appreciate what a gift they are. Thank you.

[@Don.Challenger]

All 18 episodes became beautiful. Dan/Jacob, we all thank you so very much. That's it.

[@paulbluffbearcampbell6035]

What a refreshing perspective on prototyping. This series was incredibly, clear, concise, useful and enjoyable! I watched the whole 18 parts in one binge sitting, since I couldn't tear myself away! The value of these teachings transfer to so many different types of industry and manufacturing, that far outscope just prototyping. Absolutly education pleasure! Thank you so much, I am subscribed and anxiously await new videos. Paul

[@Doodlebud]

Have used that same Mitutoyo gauge many times. They tell the tale of a system so well

[@fjn667]

Meny thanks from Sweden for this awesome video series. Watched all 18 videos in a row. Simply couldn't stop. I hope the students at UBC department of mechanical engineering realize how fortunate they are for having this level of education.

[@alanvcraig]

The demonstration of stiffness vs. strength was excellent.

[@886014]

Thank you for going to the effort to produce this series, you've opened my eyes to many different areas of prototype fabrication that I hadn't considered or in many cases even heard about! I hope you can be convinced to continue sharing your wisdom to the world through either a book or more KZbin videos. In the meanwhile I will be watching these many times again and trying to incorporate as much of this brilliance as I'm able in my own humble work.

[@dorindraghici348]

Thank you very much Mr. Gelbart for all your effort to present such precious engineering experience into such a brief and easy to follow series of courses. To gather such amount of knowledge one needs not only engineering genius but the kindness to share it. You are indeed a good man.

[@roma1530]

Thank you Prof. Gelbart, I´ve watched to all the series and learned unvaluable concepts and tips from all of them. I own a machine shop myself and I design and build machinery too but after watching your videos I feel I would need extra 200 years to get close to the wisdom one can see you have even when you teach basic stuff. Your teaching skills impressed me the most making very complex concepts so easy to understand in a so entertaining way. I celebrate you used your time and efford to inspire and motivate all of us young and not so young, beguiners and not so beguiners inventors. Finaly I loved your english, being myself not english speaker I´ve found the way you express yourself much more clear and precise than I´m used to. I hope keep making movies in any other area are so experienced too, as electronics, management, etc. Best regards from Argentina. Martin

[@duobob]

Thank you for this series, Dan. A magnificent and generous project and the best education that money cannot buy. Please do continue with sharing your knowledge and skills.

[@onecrisde]

Wow I really enjoyed this series! I learned a lot. Thank you Mr. Gelbart for producing these videos.

[@turbopunsch]

I came across your "Building Prototypes" series when searching for air bearings and finished watching the entire series now. I can't express how grateful I am that you share your outstanding skills with all of us! Your clear and precise explanations as well as getting straight to the key points I find second to none - just brilliant! I am subscribed to your channel now and I hope you will be posting more great videos!

[@AtelierDBurgoyne]

I would like to add my voice to the others in saying thank you for this enlightening series. At every step of the way I felt stimulated and discovered new ideas and knowledge about tools, materials and processes. In every segment, I was surprised to see the quality of the equipment and the completeness of your lab with the necessary machines you made, modified or bought. I salute your inquisitive mind and ability to innovate without being bound by convention. A true inventor! Daniel

[@tulpjeeen]

"electricity never drips" that cracked me up haha

[@StraightThread]

This is such an enjoyable series, Mr. Gelbart. Thank you for taking time to share your wealth of knowledge and keen insights.

[@ChrisCanMakeStuff]

That's an amazing set of videos Dan. Thanks so much for sharing. I look forward to seeing more.

[@EarthshipFreedom]

I just binge watched the entire series. Thank you sir. I actually feel smarter. Would love to see more, tutorials, shop tour, whatever your doing, im in!

[@than_vg]

Hi Dan, have watched your videos several times (and heard them on headphones while at the office even more times!) and I learn something extra each time. Really, thanks a lot... Hope you produce more videos, of any kind, in the future. Thank you again!

[@Heatseeker1]

Thank you for this incredibly educational series Dan. I hope you publish more some time, your quality content to noise ratio is higher than any other engineering video I have watched.

[@uriuriuri]

Just finished this series. Simply wonderful. Thank you so much for making these videos.

[@sascshottist1844]

I have watched the whole series, which I found really interesting. I appreciate you taking the time to upload these videos, Thank You

[@jasonblewis]

Thanks for this great set of videos Dan, I really enjoyed watching them. so many interesting ideas. One that springs to mind is the laser guide for the drill press! Fantastic!

[@petersaupe7455]

When looking at an real engineer look at his hands. I have been in engineering for over 50 years and every time I watch Prof Gelbard I understand more, and the way he explains make,s thing,s so simple and logical.

[@rikardmogensen6451]

Wow. Possibly the best videos I've seen on youtube ever. Thank you!

[@JianGongWeb]

Thank you so much for this series of extremely practical and useful tips, and for sharing your knowledge. I completed the whole series and felt like my entire approach to making things have been upgraded to a new level. Your mechanical insights changed how I think about how parts should fit and move against each other, and how to approach design and select materials/tools in order to make things efficiently, while being economical and functional.

[@EitriBrokkr]

Thank you for taking the time to make these videos, they are invaluable and absolutely amazing gems

[@mxcollin95]

Absolutely fascinating talks! Thank you so much Dan for sharing this knowledge! 👍

[@henrycawley2]

Thank you for these videos, I have only just found them but have binged through almost every one, really really helps as a young engineer to approach designing systems. I recently designed and built a CNC lathe, however after watching this series I am going to completely redesign the whole thing :)

[@neatmachine]

You are a treasure of knowledge! You have covered topics that are rarely if ever covered in engineering courses. I particularly enjoy your examples and mathematical explanations as applied to practical problems. Thanks for sharing and please produce more videos if you can on any topic to include 3D printing. I envy you your beautiful machine shop! Best regards!

[@Hirudin]

That was an incredible series of videos! Really... I am truly in awe of your expertise, I also really enjoyed watching you fire up a machine and knock out an example on the spot! I can't wait to incorporate some of the tips you laid out into my own parts. I think I'll probably watch these many more times in the future. I cracked up a bunch of times as well, I really liked your note about incorporating variable current into the spot welder and then never using it! :p Thanks to Jacob Bayless too! Man, now I wish I had a water jet cutter.

[@dgelbart]

Hirudin You can do a lot with a $4000 plasma cutter .

[@RBAERO]

Great serie of videos. Thise is a Master Class! Thanks for sharing

[@duroxkilo]

@21:10 "make sure you put the hydraulic tubing below the electrical wiring, for obvious reasons: 'cause electricity never drips, or leaks, so..." - very funny indeed. thank you so much for sharing your knowledge.. hope we'll find you on other series, pls :} stay safe, have fun

[@FragBenitez]

Mr Gelbart, thanks for all your time sharing your experiences, these are invaluable - greetings from Chile! Hope you can make more of these

[@ingmarm8858]

Absolutely outstanding series, I learned a huge amount. Many thanks.

[@kellyraysmith7697]

Thank you so much for doing this series Dan! It was 6 hours extremely well spent! I'm not used to someone lecturing and have 60% of everything be new, well thought-out information! Really cool! I hope you make more! -Kelly

[@dumyjobby]

this series of videos was so interesting and i've learned a lot of things from it. Thank you very much mr Dan for taking time and doing these very enjoyable videos. wish you well

[@loganofnorth880]

Now my skateboard will be rolling even smoother thanks to you good sir

[@olivierTUBO]

Thank you for this great videos! It is very interesting listening to you talk about machine tools from an engineer point of view! I have designed mechaincs for laser optics for many years, and i am a machine tool enthusiast. These videos are a goldmine!

[@mabsalom1]

A wonderful series, and what an amazing shop. I only hope you do more.

[@jashbaug]

Amazing, thank you very much! I will watch these again and again. I have already shared your channel with others at work. Lots of things I didn't know and things I do because they work, I now know why. Awesome thank you for the honor of your time.

[@q12x]

Fantastic series mister Dan Gelbart, I wish you can continue with new episodes and new ideas! Maybe more in depth while you are making something, explaining on the spot these wonderful ideas and experience.

[@JanCiger]

Dan Gelbart Excellent series, some of the tips are really priceless, especially for a non-machinist like me. E.g. I loved the laser pointer hack for aligning the drill - that will come useful even on a small desktop drill. I am envious of the workshop, that's really well equipped!

[@mechanicallycreative9788]

Now that's a disturbing thumbnail. All his points were put into intelligence, epic video.

[@bobcunningham6953]

Hi Dan, Thanks for an amazing video series! I lost count of how many times you mentioned tools you had made from scratch or had significantly modified. Some were deceptively simple, such as making the mill depth stop easier to adjust. Others were novel, such as the laser centering tool. Some were extreme, such as the micron-accurate lathe+grinder. I would greatly enjoy seeing videos describing the genesis of such tools. Did you ever need a tool you couldn't find on the market and didn't know how to make? How did you proceed? Thanks again!

[@kubancossack8496]

Dan Gelbart is a multimillionaire. But look at the fingers of this man - they show traces of hard work in the workshop. That's what makes a great engineer.

[@rioresearchanddev]

Awesome series. I appreciate you taking time to do this series. It is a fascinating look at how an accomplished inventor like yourself thinks and works. I also wanted to thank you for allowing us a look into your laboratory/shop. It is a beautiful lab. I will recommend this series to all of my innovation minded friends.

[@stamptrol1]

Always such a pleasure to see an obviously highly skilled craftsman explaining useful things in an engaging way! I hope you can produce more of these videos.

[@mdavidlem]

Every video is an eye opener. Thanx!

[@karlfimm]

Wonderful set of videos, thanks. I picked up heaps of useful information.

[@adrianram5524]

[@larryschweitzer1007]

"Form follows function" is beautiful to some people but not to sales/marketing. Beauty is in the eye of the beholder. Many people will think baroque is beautiful because they have been trained to look at it that way. Not formal training but peer training. Parts that don't show are beautiful to the manufacturer if they function well and cost little. Making them to a higher aesthetic standard will not increase sales/profit. Can you tell, I'm a manufacturer! Perceived value is what sells. Want proof? Many thousands of low priced Chinese lathes are sold, not even the most optimistic buyer is going to think they are getting a high quality machine.

[@vitalitikhomolov3490]

Succinct, engaging, and highly informative. Best referral to youtube video series I've received this year - will make sure to do my part and spread the word about these series. Watched the whole series and am already starting to apply some concepts in my product development work. Dan, It'd be very interesting to see a video on the jig borer.

I just finished the series and I want to echo the prevailing sentiment and offer you my thanks and gratitude for sharing your knowledge with us. I hope you make many more videos in the future. In an effort to bridge what seems like an enormous gulf of knowledge I will be seeking out a copy of Moore's book you referenced in the comments. I have seen it mentioned on forums a few times, but you have given me the motivation to seek it out.

There is no such thing as an ugly nail. That's mine now. Thanks!

[@myself248]

"Engineers ... seem to be polishing surfaces and refining away angles, easing this joint or stabilizing that wing, rendering these parts invisible, so that in the end there is no longer a wing hooked to a framework but a form flawless in its perfection, completely disengaged from its matrix, a sort of spontaneous whole, its parts mysteriously fused together and resembling in their unity a poem.

[@ledfootlou2540]

Excellent videos and beautiful shop! What type of wood is used for the workbench tops?

[@dgelbart]

All workbenches are reject laminated beams. You used to be able to buy those very cheap from laminating plants, but I think that this is no longer true.

[@ledfootlou2540]

@@dgelbart Thanks for the quick response. Are they a hardwood or softwood? They look to be holding up great.

[@dgelbart]

@@ledfootlou2540 They are softwood (Douglas Fir) and every 10 years I plane them down 1mm (at this rate they are good for 250 years). They should be hardwood.

[@StefsEngineering]

Very well done! I really enjoyed watching this series. I would love to have an opportunity to work with someone as you, so much to learn! Thank you for making these video's

[@siggyincr7447]

Thank you for publishing this series on KZbin. But I feel I need to correct you on one thing regarding the ball bearings. Those look like standard shallow groove ball bearings which really don't like to be side loaded in the manner which you're describing to remove the play. It will generally cause them to wear out fairly quickly if the loads are substantial. For the type of axial preloading that you're describing, tapered roller bearings will perform far better and with less play.

[@dgelbart]

You are correct when bearing are large, but small ball bearings (say up to 50mm) are routinely preloaded in this manner. Intermediate sizes (50-100) are used this way but typically bearings are deep groove or angular contact.

[@daylightintheswamp9315]

Thank you Dan....Adam

[@stefantrethan]

Please keep making more videos, you are a great teacher. What are the other machines you haven't explained? For example the big green one in the corner behind the granite table.

[@dgelbart]

The big machine is a Moore #3 Jig Borer, the basic machine you need if you do any precision work. This machine (no longer made) is an absolute masterpiece, has an overall accuracy of about 1micron (0.000040"), used to cost about $80,000 and available on Ebay for about $3000-$5000. If you got the room, buy one before they disappear.

[@mcoram3486]

was the compressability of the rubber bands reduce the flex

[@CalculusDogbertus]

In the first shot, behind you on the left: is that assembly from your air-bearing lathe? The two granite parallels are glued to the white (stone, marble? ) cylinders? Or are those simply white plastic covers to protect the screws from water? I cannot see the orthogonal granite spacers clearly, but maybe these are inside the white cylinders? Thanks for the great series!!

[@dgelbart]

Yes, it is part of the bed for the lathe being glued on a granite plate to get a flat reference surface. The white cylinders are steel spacers, the white squares are the nuts for putting the adhesive under compressive stress.
