The stainless steel Dan mentions for making strong sheetmetal parts might be a bit hard to pick up from the audio. I think he is talking about 17-7, which is one of a family of precipitation hardening stainless steels (perhaps the best known is 17-4PH, used extensively for high strength fittings on sailboats and aircraft, and also more weldable, but 17-7 is more formable)
Thank you for taking the time and all the hard work you put into making these videos, I'm at video 7 and I can't wait to finish the rest. Please keep making more of them.
Dan Gelbart thank you, and I recently bought a dozen spoon and they have sharp edges. what steps are taken/could be taken during production to avoid getting sharp edges in a sheet metal spoon?
Only if we had such teachers at schools and colleges. I wish we could make more such videos and such knowledge from experienced guys could be preserved. Thanks. I learnt a lot and not yet done watching the complete series.
Bead roller is great but you lose the flatness of the sheet. Most of the time is does not matter. Press maintains the flatness. You can also spot weld strips with an L section, or -^- section to stiffen plate.
I am certain that this lab is located in heaven.
These videos are great. Thanks for putting them together.
Hi Dan, thanks for the videos. What make/brand is your 100 ton press - or did you build it yourself?
The press body is from some unknown discarded press, the rest I built myself.
the gauges on that press are way to small.
Have you considered making more videos?
Ive learnt more from your 18 videos than I did during my engineering degree. Would love to learn more from you
Dan Gelbart - Building Prototypes: Metal 3D Printing got released a couple of days ago on this channel.

This video is every single thing that other hydraulic press video channel isn't. Including informative and entertaining.
Tadesan beat me to it, so true
I think a rotary deburring tool might work great for press tooling.
Nah, I just hide behind another machine. You can always stick out a phone to see what is going on.
Love these videos! Thanks
Brilliant,explained very clearly.
sir, what polymer should be used to mill embossing die for leather?
Anyone will do.
Dan Gelbart thank you, and I recently bought a dozen spoon and they have sharp edges. what steps are taken/could be taken during production to avoid getting sharp edges in a sheet metal spoon?
I couldn't afford that press. Although how about a drawing of your brake press?
Again, Fantastic knowledge you chare with us that still are interested in scients
Any ideas on how to prototype a deeper draw? Specifically, I'm trying to prototype a cowling for a small engine. Thank you
You can use repeated draws, with annealing between draws. For a shallower object you can also use an English wheel.
Best is to use heated super-plastic aluminum.
Thanks for your work, Dan

and as you can see it sheared
me: hey, that looks like a nice air vent and bend 2 in 1.
Great info again, just an ignorant question (unless I missed it) as a 'Plan B' for stiffening sheet metal, and cost, what about a Bead Roller?

Bead roller is great but you lose the flatness of the sheet. Most of the time is does not matter. Press maintains the flatness. You can also spot weld strips with an L section, or -^- section to stiffen plate.
This is a very good point. The advantage of a press is that it maintains flatness, but for may jobs Bead roller is the way to go.
