Roll cage door bar and window crank - Page 2

GallopinGhost · 06-25-2015, 08:15 PM

Dale, following the rule book, with my car, and the seat in the location that it's in, is what got me into the position where I can't operate the window. I've seen quite a few door bars that are not straight, they have some type of bend at the end where it meets the floor. Mine are straight now. I am presently thinking about a swing out kit with a bend at the end. I have mixed feelings about a swing out bar, no way in the world it's as strong as a solid bar.

Larry Woodfin's GT Truck over in the Builds section has a contoured door bar. Here's a link to the pic. It's on page 21 of his Super-10 thread.

He knows what he's doing, but this one hasn't been to tech yet.

BTW; I followed the book on my build, too. Even overbuilt it on safety stuff. I put a swing out on the passenger side for maintenance and stuff. It's not - in my opinion - safe in a crash. Drivers side is solid.

Thanks Dale. I'll have to sleep on it. Maybe the best choose is to bend the solid bars on both sides so it's easier to get in and be able to roll the window down. Probably doable, but the bar won't be straight.

A "contoured" bar is not as strong as a straight bar.

I agree if we're talking in compression or tension. In the case of a side impact or roll over, a "contoured" bar seems more sturdy over a hinge and pin...........But both are used and pass tech. Personal preference I guess. Don't wanna do any testing though

Depends on the hit. Bars that are contoured out are stronger in a side impact. Anyway, considering all the structure of a cage, there is a lot more if the structure that comes into play in a crash than just that side bar.

I have a 70 Cuda also with s&w cage, I altered the door bar to be able to use the stock handle with the window net up. You can still wind the window down & up but it's a pita. Easier to have the door open. I can post some pics if you like?

GallopinGhost · 06-26-2015, 10:15 AM

Yeah, a picture from the inside showing how it routes by the handles would be great. I have a challenger, not sure if the handles are in the same location or not.

SFI specs allow bends in door bars, at least on a 8.50 car...not sure on the lower E.T. cars but doubt it. My personal opinion on swing out bars is not a big fan. Just looking at them in different variations not sure I'd ever put one in my personal car. I see no way ity could be as secure as a PROPERLY welded bar. BTW dale I've used a couple of the cheap, lite cable operated power window set ups from the newer cars on cars not designed for the...works great, however there is a little fab work involved. Can be done for less than 150.00 both doors less wiring and switches.

Ask Jeff Lane about power windows, a few years ago he had one fail in the down position (and if I remember right it was in eliminations, not qualifying), got booted and lost the round. I guess I'm a big fan of simple mechanical things that are less likely to fail. Also wonder how happy they are with 16 volt batteries.
