Roof raise supports: 11 gauge???

Hey I got a flat nose International 72 passenger

Just got the roof up with all thread, and welded in about 4 square tubes in the hat channel

the hat is just over 1 1/4 wide, and the best I could come up with was an 11gauge square tube shimmed up with an 11 gauge flat bar. I cut the flat bar to just 9" on either end (the length inside the original channel) so the middle section is just the square tube. It fits snug and holds tight after welding.

EVERYBODY says go 14 gauge for the channel supports but metal in my area is just ridiculous, most places just told me they won't even sell materials.

I used a staggered method like Wes from transcend existence on youtube, so all the weight isn't in the dead center, but I'm starting to get a little paranoid about the weight difference.

Any tips on using 11 gauge for the supports? I'm a little worried about the weight difference but I'm sorta between a rock and a hard place here.

Thanks

Much ado about nothing. When raising a roof,the strength of the additions is much stronger than before. Theres a ton of ribs your adding to.
Go to the UserCP and fill out your profile with bus info and location, it helps answer your concerns.

I am far too busy and lazy to do the user cp thing... but I will eventually

However, if you're right that takes a huge weight off my shoulder. I just simply can't find a single person who did anything other than 14g for the channel supports. So THANK YOU.

Let me ask you this: what about the roof transition framing? I cut inside the first window channel (like Transcendence). For some reason I felt I shouldn't put the 11g up there being as its the roof and not the walls, but the best I can find is 16g which I think is a little light

What do you think?
