NASA rules for the Tacos:

4.2 Gusset construction
Gussets are required to be made as follows:
1. U-shaped sheet metal (taco shell). Refer to figure 253-
34 below. Minimum thickness is .040” (1 mm). Minimum length along the unwelded side of the gusset is 3 times the tubing diameter.
2. Round tubing. Minimum length of the longest dimensions is 3 times the tubing diameter. Minimum tubing diameter is 1” with minimum wall thickness of . 083”. Maximum diameter and wall thickness is per the materials in table of section 6.6.
3. One or 2 triangular plate steel gussets with combined thickness equal to the tubing which is being gusseted. Minimum length along the unwelded side of the triangular gusset is 3 times the tubing diameter.
Any plate or u-shaped gusset that is welded into a joint location where it can block the view of the welds between the tubes being reinforced must have the corner cut back to enable visual inspection of the tube joint. This is illustrated in figure 253-34 and typically looks like a bite out of the corner of the gusset.


Definitely Carl! I was thinking that a full sound system with three subs, four amps and twelve speakers should do it! Or not... If anything I thing that a few hours with a hole saw will get the rest of the inner door in good shape!
