^ dont forget the PVC X-Brace!

i'll have to look into that. Although with my car being lowered, i'd have to use smaller diameter PVC so it wouldn't scrape the ground. Guess I will have to bite the bullet and reinforce it with the hot glue method.

man why hadn't I though of this?!?!! Finally found the perfect material for a roll cage in my cabrio. We all know the cabrios flex a little bit due to the lack of roof. I've been hesitant about adding a cage because I didn't want put anything in it that would make the ride too stiff and lose that engineered flex. The PVC will be perfect because it will flex as the car does. I'll need to make a PVC strut bar for the cabrio as well!

Has anyone checked with any racing bodies (SCCA, BMWCCA, NHRA) to find out whether this is legal. I haven't heard that question asked.

Just pick up the rule book.

Why would you weld it when they make adhesives just for this purpose. Think about this, if you have a sleeved connection with 2" of overlap and you use spray adhesive that's pi*diameter*2" of surface area. If you weld it you get much less stiffness because you are only securing it at that one point.

Also DO NOT USE ABS, ABS is strong until it breaks then it shatters catastrophically. Of course I've never used it in a load bearing application but those cheap ABS plastic hoses meant for carrying compressed air, when they fail watch your neck ABS needles EVERYWHERE! PVC will yield much like steel or aluminum which is what you want in a cage application ,not snapping or shattering but bending and therefore absorbing the impact, instead of your head.

No, ABS is too brittle, won't have the give you need. PVC like we said is where it's at. Go to Hydroscape, they will hook you up.

is abs better?

[bataangpinoy]

noo its the white industial one used for hot water piping that you want.

hell, i'd even look into abs or polypropylene(not spelled right)

[mamzak]

IIRC the black stuff is the strongest...

[619E30]

What pvc should I use. Plumbing kinda shit?

[bataangpinoy]

hell yea. pm'd

[mamzak]

True enough. We should make these and do a group buy. Anyone down?
