Whoa!, hold up on that thought! Its definitely very expensive but not 7K expensive.
Properly laid out I'm pretty sure the whole thing could be made out of a 3'x4' sheet or less, which would be 12- 12"x12" sections. So thats putting it at something like $3,912 according to that websites price of $326, which was also the only place I could find pricing that didn't require a quote. BUT, I'm pretty sure that price is extremely inflated over what we, or any company, can buy it for. I'm gonna try a bit harder next week to track down the price my company paid for the 601 Inconel sheet.
I know we get the Titanium tube for $33 a foot and the ferrule is around $90 (which I'm told we are getting a hella deal on)
If I ever get a decent estimate on the materials price I'll post it up, as for a price on the time I have into it, I dont even know really where to start, I'm just gonna leave that one alone.
