Re: 22" project - the saw dust flies!

Well tonight some metal dust flew. I'm still waiting on my secondary holder and spider to arrive, so work on the upper cage is on hold for now. I did have a friend plane my uprights - I'll reveal the details on those later.
I found a great local metal shop thanks to the guys at the UNL Physics/Chemistry Instrument shop. I got a better price than I could find online and it was ready same day. I decided on 6061 aluminum for the triangles and bars. 1/4" for the triangles, 1/2" for the bars. Both cut easily with my bandsaw. I punched the location of the apices and pivot points so I can accurately drill them later. I also sanded the edges to smooth them up a bit and take the sharp edges off.
Piece of advice - wear gloves, goggles, and a dust mask when working with this stuff. It gets HOT when cutting and sanding, and metal dust isn't great for your lungs.

I'll get some pictures posted later this weekend.
Thanks,
Brian
