This is a great series of videos, the subject matter is calmly and professionally delivered by a true master who puts a lot of effort into making complex notions easy to understand. I strongly recommend that anyone interested in high precision machining watch each video of this 18 video series several times over. These videos and Mr. Gelbart are pure gold!!! Marc L'Ecuyer
When I did my research into Dan's background in optical design and engineering I wondered how he and his company delivered the cameras at the prices they did. Watching him describe his techniques for simplifying manufacturing of parts. I run a small engineering company and am self taught. I find listening to Dan more helpful and informative than I can say. A truly great engineer.
Dan Gelbart So I suppose the aspiring backyard engineer will have to build their own, haha. In all seriousness, very nice videos, thanks for sharing! :)
Bravo, Dan! I wasn't expecting a masterclass! Your customers clearly appreciate your skills, and now, so does the world. Thank you for sharing this. The world is richer for it.

Dan, I believe I'm ready to begin a second refresher trip through your excellent series. I believe in a year and a bit more your current project might be winding down and you can begin to turn your attention to helping us all out with some more like these.
Using youtube-dl and one command you can download all these videos. Add them to a playlist, copy the playlist id, run youtube-dl with the options [-i ‘PLAYLIST ID’]. These days things can vanish without a trace, my advice is to save anything you’d like to view again. I thank Dr. Gelbart for these master class reference videos.
Cannot thank you enough, Dan. Not only for taking your vast knowledge and experience and putting it online for all to use and enjoy - but also for making it a master class and highest level of quality one can produce. Both amateurs and professionals will find things to gain from this. Much appreciated.
Dan, I have had vast experience in machine design and die making but have found true gems in every one of your videos. What I find most impressive is your generosity and willingness to share your knowledge.
@dgelbart Is that the bed of your air bearing lathe in the background, it looks like the granite T blocks you made for yours with those white bolts (would love to know what those are or where to find them. Id like to try my hand at making one myself. It would be awesome if you would do a more thorough breakdown and overview of your beautiful lathe.
Dan, I have enjoyed watching your video series, thank you so much. I am an advanced amateur metal worker and have a small shop in my garage for tinkering around. I love your spot welder. Do you have any information you can share about it's specifications? -John
Unscrew the lens from the camera and find a lens with a focal length of 40 to 100mm, preferably 10-20mm diameter. Mount lens at ens of a tube with the camera at the other end, tube length being about twice the focal length. Tube length will set the focus and magnification. Paint the inside of the tube with flat black paint.
Dan you are the man I watched these videos a few years ago Someone brought up your name yesterday, so I started watching again Learning a lot more the second time around. Thank you for making these videos public, and not just for Ubc engineering students Love you!
To someone with literally zero experience of machining, the passion for your subject is infectious! I feel like I've absorbed more information listening to Dan than from many hours spent on RUclips watching How To videos. Nothing better than seeing someone at the top of their game ! Many thanks to you 🎯
Neceros Most high performance parts need to be metal, and 3D printing in metal is terribly expensive and slow. For plastics 3D will take over and replace several method I'm discussing, like molding in silicone molds etc.
For the spiral springs: "I can take any plot of force versus distance that I want". I believe the force would need to be monotonically increasing. I don't see how you could make a spring that delivers a high force initially but a lesser force when fully compressed?
Also, what if you are talking about the compression of a tensile spring? There is a spring called a zero length spring. I think that will answer your question. It's also fascinating.
Hi Dan, thanks for all the great videos, I learned a lot! Dan, I need to talk to you regarding a project I am working on to see if you are interested on taking; let me know please.
thank you sir for this wonderful tutorial, I didn't understand the the 'U-shape' pieces thing at 2:59. could you please suggest me a book or search term to better visualise it. thank you :)
Thank you for the amazing videos! For the last item shown, a chuck, pieces of spring? steel were used. I am curious about how the ends were fastened. The fasteners looked tubular. Spot welded to the fasteners? Ends bent and inserted into slots? Thank you!
I've watched your entire series on building prototypes and love it. I really appreciate you sharing your insight here. I enjoy your simple/elegant approach to design. It's engineering poetry. Can you tell us more about your spot welder? I'd love to build one very similar to it.
Take any 240V 2-3KVA transformer, remove secondary winding and replace by 2 turns of annealed copper bar having a cross section of about 5cm2. You should get about 3V, if not add one turn. Connect winding to moving electrode with a stack of flexible strips of similar cross section.
Thanks. Most spot welders' leads are on a pivot mechanism. I especially like the linear clamping approach that yours uses (and the interchangeable leads). I'd love to see an image of the inside of it... how the leads are insulated from the chassis, showing the mechanical motion of it.
Dan Gelbart Yeah I read a bit about it on Practical Machinist , where it was mentioned it was no longer imported to the US. Occasionally I see used ones pop-up so was curious what about it you like.
First video I have watched in your series and very much enjoy your presentation of this series so far.In this first part there is a lot of discussion in regards to Water Jet Cutting you are starting to sound like you are a salesman for this process, they are an excellent piece of equipment with a price tag to match but as always good equipment always arrives with a high price attached.My reference to your channel came via Dale Derry.(Metal Tips and Tricks).I always enjoy watching RUclips channels such as yours, as from my experience you can not know everything and someone else will always have better way to do things than you. so i looking forward to more from you in this series. Regards Peter.

THATLAZYMACHINIST I totally agree with Marc L'Ecuyer!
Exactly Mark, you both are sharing gold for free. Thanks!

Nice detail: the glue-up for the precision lathe bed is in the background of this video.
blown away! The only way to thank you is to mention that you will be the inspiration behind the movement in my future gizmos! No Patreon?
Thank you for the knowledge on safety. I will watch it again . Lots of things I didn't know. Life and limb saver. Thanks a million.
I like the Makino milling machine on your left
The KE55 is a great machine, they were crazy to stop making it. everybody is looking for one.
I dont quite see who needs to build a prototype and has a water jet cutter next door.....
Anyone developing new technology needs to build prototypes and the ones successful at it buy a waterjet cutter to save time.
Dan Gelbart
the ones successful at it probably dont need to watch such instructional videos anymore. How much does one of these cost ?
manu de hanoi About $100,000.
Dan Gelbart So I suppose the aspiring backyard engineer will have to build their own, haha. In all seriousness, very nice videos, thanks for sharing! :)
or you can join Techshop and use theirs for about $125 per month plus a fee to use the Waterjet. That's what I plan to do one of these days.
Bravo, Dan!
I wasn't expecting a masterclass!
Your customers clearly appreciate your skills, and now, so does the world.
Thank you for sharing this. The world is richer for it.
Thank you for this set of videos. Best information videos on You Tube without doubt.
You need to watch Tips from a Shipwright then. Louis is the Yoda of delivering information.

A youtube channel that assumes that you know about Hooke's law, this is awesome, I'm going learn a lot from this!
This Genius is a true master at both, machining and presenting. This talent takes time to master. No school can do that for you.
These videos keep popping up in my feed and every time I think Dan Gelbart is Noam Chomsky from the thumbnail ;p
The amount of freedom and ideas these principles give is beyond joy.
Dan, I believe I'm ready to begin a second refresher trip through your excellent series. I believe in a year and a bit more your current project might be winding down and you can begin to turn your attention to helping us all out with some more like these.

Daniel, such a treat to see you as a presenter of design and innovation. Good things have happened in your life, by your effort. i salute you.
My Co-Electronic Expert in practice, and design innovation. Good man to collaborate with , or be trained by
this guy is solid gold boi
Dan, I have had vast experience in machine design and die making but have found true gems in every one of your videos. What I find most impressive is your generosity and willingness to share your knowledge.
I sure enjoyed this series. Wish there was more
Hi Dan I'am new to this and I look forward to watching your videos thank you 😊
Dan.
I have watched all 18 of this series and I am truly impressed. I learned a lot. Thanks for sharing.
@dgelbart Is that the bed of your air bearing lathe in the background, it looks like the granite T blocks you made for yours with those white bolts (would love to know what those are or where to find them. Id like to try my hand at making one myself. It would be awesome if you would do a more thorough breakdown and overview of your beautiful lathe.
Dan wrote a brilliant paper you can look up that gives a better idea of who you are watching in this series. "Beginner's luck"
Dan, I have enjoyed watching your video series, thank you so much. I am an advanced amateur metal worker and have a small shop in my garage for tinkering around. I love your spot welder. Do you have any information you can share about it's specifications?
-John
+John Leech John, look at the Spot Welding Video, I'm answering many questions about it in the comments section.
Dan,
Thank you for the most interesting videos.
I've looked at six so far.
Geoff
Amazing. One of the very best things on RUclips. Thank you.
Hi Dan, Thank You for your wonderful videos. Could you please tel me how to put the reverse camera on my lathe. Just a few key hints. Thank You
Unscrew the lens from the camera and find a lens with a focal length of 40 to 100mm, preferably 10-20mm diameter. Mount lens at ens of a tube with the camera at the other end, tube length being about twice the focal length. Tube length will set the focus and magnification. Paint the inside of the tube with flat black paint.
Hi Dan ,Sorry to be such a monkey, but is it a digital signal , what must i connect it to?
@@basievanwyk8686 You just plug the camera into the display. Is is actually an analog (NTSC) signal.

it
Dan you are the man
I watched these videos a few years ago
Someone brought up your name yesterday, so I started watching again
Learning a lot more the second time around.
Thank you for making these videos public, and not just for Ubc engineering students
Love you!
Probably the best series on manufacturing processes
To someone with literally zero experience of machining, the passion for your subject is infectious! I feel like I've absorbed more information listening to Dan than from many hours spent on RUclips watching How To videos. Nothing better than seeing someone at the top of their game ! Many thanks to you 🎯
Nobody is born with experience in machining. If you have the interest, the knowledge will follow.
One video down, 17 to go! AWESOME.
4:40 What is that matetial type of spring?
The springs are Nitinol, a Nickel-Titanium allow very popular in medical devices. It has an elastic range which is about 10 times of spring steel.
@@dgelbart Really Interesting material. I will look more about them. And thank for sharing your knowledge.
This is absolutely fantastic, thank you so much! Just invaluable!
Great video. I'm a professional machinist and am still learning a huge amount from your videos. Thank you for taking the time to make these.
Absolutely wonderful.
Your videos are very informative to me. Thank you very, very much for sharing your knowledge, kind sir.
Awesome. Thank you, Dan, for sharing.
Hi DanOne subject I would appreciate hearing you talk about would be patents - I assume you must have experience with them.RegardsRandy
Looks like the bed of the high accuracy lathe curing in the background...
Right you are!
Dan
Wiki dan gelbart.... This guy is awesome...
The profiled spring cut on water jet with variable spring constant is next level! Really awesome.
How much would you change your stance on these tools with the proliferation of 3d printing recently?
Neceros Most high performance parts need to be metal, and 3D printing in metal is terribly expensive and slow. For plastics 3D will take over and replace several method I'm discussing, like molding in silicone molds etc.
3d printing is a fad for idiots.
Like a mule with a spinning wheel.
Does anyone know who can help me build a prototype (electro mechanical) - Thanks?
Excellent techniques. Perhaps you could make a detail instruction video on how to make the lathe.
For the spiral springs: "I can take any plot of force versus distance that I want".
I believe the force would need to be monotonically increasing. I don't see how you could make a spring that delivers a high force initially but a lesser force when fully compressed?
+dougfeig Any snap action spring does that (e.g. microswitch, keyboard key etc).
+Dan Gelbart Good point, I will ponder it some more. Thank you so much.
Also, what if you are talking about the compression of a tensile spring? There is a spring called a zero length spring. I think that will answer your question. It's also fascinating.
You are amazing master!!!! When grow i want to be like you!!!!
You are brilliant. Thanks for sharing!!!
Valuable information for anyone in manufacturing!
the water jet is an amazing piece of hardware, thanks for sharing!
Thank you so much for this master
Amazing video series. Love it..
Dan, do you know someone reliable who I could use to help me build an electro-mechanical prototype of my own design; I'll pay for the expenses?
Unfortunately no.
Hi Dan, thanks for all the great videos, I learned a lot!
Dan, I need to talk to you regarding a project I am working on to see if you are interested on taking; let me know please.
Sorry, too busy.
You seem to be very much pro water jet, what does the water jet deliver over laser or EDM.
Waterjet can cut practically any material, EDM is limited to metals, laser has material and thickness limitations.
Where are you from? T
hat accent is very familiar.
Originally Israel but spent most of my life in Vancouver, Canada.
thank you sir for this wonderful tutorial, I didn't understand the the 'U-shape' pieces thing at 2:59. could you please suggest me a book or search term to better visualise it. thank you :)
"U-shaped pieces" means pieces where all the bends are parallel. Such bends do not require changing the width of the brake tools.
+Dan Gelbart thank you sir :)
Thank you for the amazing videos!
For the last item shown, a chuck, pieces of spring? steel were used. I am curious about how the ends were fastened. The fasteners looked tubular. Spot welded to the fasteners? Ends bent and inserted into slots? Thank you!
spring steel strip is from a clock spring, ends held in place by socket head M3 screws.
+Dan Gelbart Thank you, I see it now. The strips are inserted into spiral slots. The screws only need to retain them in the slots.
I've watched your entire series on building prototypes and love it. I really appreciate you sharing your insight here. I enjoy your simple/elegant approach to design. It's engineering poetry.
Can you tell us more about your spot welder? I'd love to build one very similar to it.
Take any 240V 2-3KVA transformer, remove secondary winding and replace by 2 turns of annealed copper bar having a cross section of about 5cm2. You should get about 3V, if not add one turn. Connect winding to moving electrode with a stack of flexible strips of similar cross section.
Thanks. Most spot welders' leads are on a pivot mechanism. I especially like the linear clamping approach that yours uses (and the interchangeable leads).
I'd love to see an image of the inside of it... how the leads are insulated from the chassis, showing the mechanical motion of it.
Is that a Makino KE-55 in the background? What about the machine made you choose it?
Thanks
It is a great machine but no longer made.
Dan Gelbart
Yeah I read a bit about it on Practical Machinist , where it was mentioned it was no longer imported to the US. Occasionally I see used ones pop-up so was curious what about it you like.
Everything.
