Fabricating Electronic Chassis with Traditional Sheet Metal Tools
Музыка
This video is for hobbyists who may be interested in making chassis for electronic equipment. Eric from Rare Waves demonstrates use of traditional sheet metal working tools to create the control panel for an analog synthesizer, the Grendel DC-2e 2019 Limited Edition. The main focus of this demonstration is to illustrate some practical aspects of using a punch press and pan-and-box brake.

Thanks for the demo, Mr. Archer, this is great stuff. I will definitely look into our press, break, and punches that are available at school!
Awesome to see it in action!
I've been drilling my aluminum faceplates by hand, and I'm not that satisfied with the process or results. I'd been thinking of punching. Did you get your machinery second-hand?

The punch press and its tooling are second hand + custom built. The shear and brake weren't hard to find new at affordable prices
you have a massive amount of information in your brain...it must be saved

Thanks! When I started out doing this stuff, I wished I could find more information on punch presses. I hope this helps somebody.

@@EA78751 Your video sure helped me, thanks a lot. Of all the "machinist" videos I studied, none were as helpful to me at my present stage of knowledge. Your video answered every question I had, and luckily there were a few similar punch machines on eBay so basically I was able to duplicate the punch press portion, next challenge is the correct tooling and custom made adaptors for my application. My Greenlee chassis punches have carried me well for 50 years in Ham Radio, but no longer are meters and switches round, or Imperial dimensions.

@@georgedowell3244 Thanks for your kind message. Still punching here. We got a CNC router recently, but theres still lots of jobs the punch press is better at, and safer, quieter too.

@@EA78751 Thanks again for making everything understandable, and congratulations on a new a CNC router there. Something like that is not in the cards for me, I can't program worth a darn (and too old to learn). Watching your video I wondered about the need for the adjustable protractor trick, but now that I have a similar punch machine set up and have some more experience with it, I can now fully appreciate that little life hack you came up with with the protractor- a very quick and precise method to keep rectangular and square holes aligned with the edges for sure. I've now learned that just one or two degrees "off" makes a noticeable difference, but the protractor quickly and precisely adjust that error out. Very well done and thanks again. for saving me untold frustrations! Geo.
Few people would have these machines and punch dies are very expensive so unless a lot of sheet metal work is done it would not be worth it .
