how strong is jb weld?

How strong is jb weld? I dont have a welder and I dont know anyone who has a welder also. So I wanted to make my own roof rack out of conduit. I have a miter saw that I would just to 45 the corners. My question is how strong is jb weld. It would be used on the 45 angle corners and down the middle to act as a T. I used it to jb weld a BOV on my turbo integra and held great, but thats PSI. I will just use it to carry my spare tire and also maybe some lugage. I dont go off roading

It will be bolted to my stock rails

In my experience, JB Weld is about as strong as Elmer's glue.

Used within a VERY specific range of use, it can be incredibly strong, but not for what you're considering. Not to be a wet blanket, but I don't thing conduit will work that well as a rack, either. I would think that the weight of a spare tire would eventually bend it, what with all of the bouncing and etc. that your vehicle goes through. Gas pipe would work better, but then you're back to welding. But, you can buy a 110volt small mig welder pretty cheap these days. I think you could get a non-name-brand for $100 or less. Then, get some scrap pipe and practice for a couple of days. You'll get it figured out, and then you have a new tool and a new skill!

Oh, and JB Weld DOES NOT hold up to race gas. There's a (funny) reason I know this...

Duck tape would probably be just as strong as the JB. If you talking about using thinwall EMT conduit (typical conduit we run wire through) it will not support much weight at all. You could probably use rigid EMT minimum 1" and it would be much stronger. Also, the rigid will hold up to a welder. Just my $.02.

Might wanna think about the liability problems if your roof rack comes apart and dumps a tire on the highway. A good rack is only like $300 it might be worth saving for.

It Wouldn't Be A Project If Everything Worked Right.

I still think you should learn to run a small MIG. A skill you will find uses for the rest of your life, and it's actually quite fun.

But, having said that, I suppose you COULD go to Lowe's or Home Depot and buy galvanized or black pipe, and also the pre-made joints. Between some good pipe-dope and a pair of stout wrenches, you might be able to get it solid enough.

But, you really should weld it...
