1/2 diameter Rebar
1/8" thick steel washer or discs (in this case Ryan used the water jet to cut them out of some angle iron I found)
Machines Used @ TechShop San Jose:
Fixture table (welding table... that I cleaned after I was done BTW)
Pedestal Disc Sander
Hand Tools/misc items used:
Hammer (just in case... hammers can fix anything!)
Welding Helmet, gloves, general protection
Fixture/hold down (magnet and clamp)
Safety glasses & ear plugs too!
Mad welding skills
(Someone who is signed off on the waterjet already since I want to make it yesterday!) Thanks Ryan.
All done @ TechShop San Jose!
Step 1: Didn't have washers or discs handy... so waterjet time
He had to rig some clamps to get it done.
Afterwards it was a few simple taps with a hammer to get them free.
