The 6061 actually wasn't as expensive as I would have thought. I think it came out to something like $200 for all the 6061. Doesn't include hardware and adjustable handles, etc. I would put that at another $50 for metal adjustable handles and all hardware. I think we have something like 20 hours of work into it, but we also weren't the most efficient in the beginning. Programming the dxf into the machines takes a bit of time as does setup and actual running of the program.
I have no idea what my time's worth. But $250 in materials plus 20 hours of work if I were to do it again. I'll sell it to you for $750.
