I don't know if it makes a difference but I put a pig in there about 2 inches on each side of the cut . Thanks

ah righto. small lesson here, a tube is less likely to bend than a solid bar. I highly recommend at least a shallow gusset there, I'd hate to see all this beautiful work go to waste.

I think you need to qualify that statement. If you have a tube and a solid bar with the same OD the solid bar is less likely to bend. I can prove it with math.

However, given the same amount of material, you can make a tube with a larger OD than a solid bar and the tube will be stronger. But that is really just because it is larger. Tubes are more efficient structurally than solid bars.

I do agree with the area of concern and think a gusset would help.

Remember, weld your gussets in on the outside (or inside) of the tubes. Not right down the middle.

I'd put the gussets on the inside so that they can be covered by the seat pan and still keep the clean lines.
