RollCage fabrication

Re: RollCage fabrication

Most any cage I've done has been moly, and I too use the ER70 in 3/16.

PYSCHO...I owned the Cad powered Mustang in the first PGD's that eventually ran 9's with junk on a bottle. Shootin for 8's is by no means a difficult task with the progress some vendors are makin in part availability for these things now and the less weight I'm haulin. While the article in HR this month was kool, you should see how much power the real Cadillac vendors produce!

Re: RollCage fabrication

Those who can fabricate - and I mean TRULY fabricate - have a skill I will never have. My hat is off to these fantastic craftsmen. Wow! Nice work, guys!

Re: RollCage fabrication

My major undertaking. 95 Dodge Avenger I decided to try and build into a chassis car. I'm a year into it.
I also built my Valaint from a $300 car to a winning drag car.
It keeps running so I have some free time and started the avenger build. I enjoy building them almost as much as turning on the win lights. I'm already thinking about the next build though, thinking street rod and hot rod at the same time.

Re: RollCage fabrication

Both are nice and cool, but I really dig it when people convert FWD to RWD .

Re: RollCage fabrication

Wow. I’m impressed. Any of those cages 4130?
If they are, is anyone annealing the welds?
What kind of filler rod are you using on those punchplates?

Is it a complete trial and error process? I wonder if I could mock a cage up with PVC pipe or something then take that to a tube bender. Anyone know of any techniques like that?

I gotta buy a bock on this

Yep 4130! Look at the bars. Tig welded w/ER70 rod as well!

Re: RollCage fabrication

I take 1/4 inch tubing and bend it to fit the area and then bend the Big tubing to the same outside dimention. you can use the 1/4 tubing over for other parts of the cage.

It works for me!

I'll be doing some of this next week for the Kia.
I got the Seat Installed today so I can measure the area for the cage.

Re: RollCage fabrication

Here's my six point that I put in about 3 years ago. Pro-Street style rear bars so I could still use my back seat and swing outs so it's easy to get in and out of.

I also used an S&W prebent kit and it fit real nice.

Re: RollCage fabrication

I have a 67 Chevelle and want to put a S&W 6 Point cage in it. Is it really necassary to tie the cage back to the frame, or can I form plates to match the contour of the floor and weld the tubes to them? I want to install the cage properly but I am not really all that cracked up about cutting monster holes in my floor.

And if anybody could shed some light on something, how does the cage getg painted once it is in the car without making an overspray mess inside the car.

Re: RollCage fabrication

The real answer is "depends". I don't know the requirements of your sanctioning body, but SCTA and therefore ECTA are OK with floor plates. Of course, in a unibody car, you pretty much have to do it that way. If you can get to the frame, the car will be stiffer, of course. I've been told that SCTA is going to require 1/4" plates (1/8 were OK in the past), so I just did mine in 1/4, even though the S&W kit came with 1/8 plates. I try to use 6x6 plates, but the rule book actually says the outside perimeter has to be 22" (5x6). Remember that the tube does not have to land in the middle of the plate. The plates can be bolted to the floor as long as the tube is welded to the plate and there is a back-up plate of the same dimension on the underside of the floor such that the floor is sandwiched between the plates. Most of mine are welded, with the exception of teh front down bars, which I bolted - minimum of 4 ea. 3/8 bolts, Grade 8 or better. This makes it possible to build a "bolt-in" cage that can be removed from a daily driver.

Hope this helps

I also have a 67 chevelle that has 12 point cage.NHRA requires that if the car has a frame the cage is to be tied to it. When I figured Ware the cage was going, I cut out enough to weld the cage to the frame and kept the piece I cut out. After the cage was in, I made cardboard templates to fit around the cage then trimmed the stock pieces and welded them back in place around cage .My car is a aqua on aqua car with full interior ,when I painted the cage to match ,there was no interior in it . As for over spray the only suggestion is lots of time and masking. I used more base color painting the cage than I did on the exterior.

Re: RollCage fabrication

On the paint, Mr. Turk suggests that you brush paint it. Seems like it is common to modify and otherwise mess with it (adding a helmet hook, tach mount, more gussets, etc) so you have to grind it and touch it up anyway. Mine is still naked, but eventually I'll brush on the Rustoleum blue hammer finish like I have on the rest of the interior. I KNOW mine isn't done yet.

Re: RollCage fabrication

Have you guys tried POR-15 to paint your cage? Goes on with a brush and smooths out as it dries. Work great.
