Roof raise: Square tube and rectangular channel

[IC08]

Attachment 56813Hey all, I've kind of taken it for granted I would have to shim up my square tube with some flat bars but after trying to weld them together (for the first time) I just never felt great about it.

heres some pictures, should I just plug weld them? any tips would be great. I havent been able to get c channel made in my area at all

mostly I'm just worried the two pieces arent gonna be strong enough or something or that they will seperate. maybe weld in the tubes and hammer in the shims after..?

thanks

What area are you in? I could get you channel in central FL, but am super busy with some projects at the moment.

Im in IL so its a bit of a drive, but thanks. Maybe the coast is better but metal price is 3 times over what it usually is here, I've already got square tubes and some flat bars so I'm really hoping it will work out.

Cant seem to find anyone with pictures who had to shim up their tubes, though it is mentioned a few times.

I mean once you weld the two pieces together (correctly, that is) do they function about as good as would a single piece? Would you weld down the length of the shim/tube or would you drill and plug weld?

Go to the UserCP and fill out your profile with your location so those in your area can chime in when necessary. Your welding is sufficient, remember there are over 20 so as a whole they will be more than strong enough after welding them into the bus.

everybodies always bugging me to fill that thing out! I guess I'll just go do it then

But thanks, I'm a total newbie at welding so thats pretty much what I was hoping to hear. Or at least that someone had tried it before but hey we are a community of pioneers, right?

I'll be back with pictures later, time to go amish on this roof!
