Question to the machinists on this list:
I am considering doing some basic sheet metal bending/braking for
making the PSU and RF deck cabinets on my GS35B linear from scratch. I
have seen the nice work of Hank on his page amp:
http://www.wv7u.com/yc156amp/pictures/procav2.jpg I am attempting
something much simpler than Hanks work, but the picture is just to
illustrate the general technique I am looking to use. Hank has made
most the pieces of his cabinet from sheet metal, it looks like. I
would like to bend "lips" like the ones on Hanks amp internal parts.
This would enable me to screw the parts together without using too
much angle stock. Another picture that illustrates the concept:

Question: what aluminum alloy is the easiest to use on a hobby
sheetmetal brake? (I have on earlier projects used some scrap material
I picked up cheap that had unknown properties. However this material
was way to hard and therefore very difficult to use). I am going to
buy a couple of large sheets for this and later projects so it would
be worth the time to do a little research.
I have seen an aluminium alloy guide here
http://www.onlinemetals.com/aluminumguide.cfm but it doesn't help me
much.
Question: what aluminum alloy do you use / would you recommend for
general purpose hobby / ham radio use? The material should be soft
enough to be used on a general hobby / home ship metal brake.
