materials:


The mark 2 design uses 4 and 8 foot sticks of 1/4", 3/8", and 1/2" aluminum c-channel "trim sticks", available
at most hardware stores (though mine don't keep much in stock) I connect them together using 1/4" stainless
steel phillips pan-head bolts and stainless nylon lock nuts. You'll need two 1+1/4" bolts to get through and
lock on the 1/2" sticks. Six more 1" bolts will be needed on the 3/8" sticks. If you can find the 1/2" and
1/4" sticks in 4ft lengths you might want to get them instead of 8ft sticks, to save yourself the time cutting
the 8ft sticks in half. (it doesn't add a lot to the cost, and your time is worth something)

I'd strongly suggests avoiding steel c-channel (much heavier, harder to cut/drill/file/fit), and also only use
stainless steel for the nuts and bolts. (to avoid rust if it rains) Also pay the extra for nylon lock-nuts, to
prevent "spontaneous unscheduled disassembly" and a hunt for where the nut and bolt ran off to.

So each frame requires:
- 2x 8ft 3/8" aluminum c-channel
- 1x 4ft 1/2" aluminum c-channel (or cut 8ft sticks in half)
- 3x 4ft 1/4" aluminum c-channel (or cut 8ft sticks in half)
- 2x #10-24 1/4" x 1+1/4" stainless phillips panhead bolt
- 6x #10-24 1/4" x 1" stainless phillips panhead bolt
- 8x #10-24 stainless nylon lock nut
