The first assemble has 6 pieces, the second has 8.
Of the 14 total pieces 7 are the same (part1), they are .250" aluminum 1.500" X .622" +.000/-.030 for tolerance.
2 other (part2) are very similar, with one only having extra relief add, this relief could be add with a sander at the time of welding. They are 1" dia aluminum 1.766" long and a 7/16-14 unc 2b hole (I can supply these part too) I'd like to keep a +/- .005 on the outside profile on these.
Parts 4&5 are similar as well being of 6ga aluminum 13.750" X 6.625". To make these parts you will need some form of a break, capable of forming a 5/16 inside bend radius (I am flexible on the bend radius but remember the larger the bend radius the strong it is). If you were to supply me with your bend allowance I can model it in.
Parts 6&7 again brother/sister parts of .250" aluminum with the larger one being 13.00" X 5.25" and the small being 13.00" X 3.00".
The last part is from 8ga aluminum is 11.25" long by 4.5" wide and may need to be ran through a slip roll as it needs a 4.75" inside radius.
So here's the deal I'll take quotes on all the work (will need to weld both assembles), or individual groups. These are R&D at this point, if the work out #'s could be in the 100/year of each assemble.
I have these drawn in Pro/E so can export to a few different formats.
