Doing a really difficult 4130 cage at moment

[dandimand]

In 22 yrs of doing this this is by far the hardest one . the front down tubes took me 8 hours to do Its on a nissan 300 zx with T roofs that still need to be removable and all the stock interior and dash brace is to go back in I will post some pics in the next few days what a pain this one is .

I can believe it, my best friend does cages and when I stop over there I many times wonder how the heck he got the tube into that location and then the fun part of welding it to the halow bar.

And then the kid your doing it for brings his buddy over and his buddy says
( Oh I could of done it but I dont have a machine at home )

When that happens you got just chuckle to keep from strangling the kid to death.

dandimand, howd you get into putting cages in car? School or self taught? I know how involved they can be and curious how people get into this work.

I'll swap you that cage for a two seater gyrocopter I've been involved in, 64 hours of just welding so far and more to come all in 5/8 and 3/4 diameter tubes and wall thicknesses of .035 or .049. It's been the toughest job I've had to do in years, I've enjoyed it but it sure has been tricky getting in amongst a myriad of tubes coming in from all directions.

Well the cage is done have to do a parachute mount if i can clean the shop up abit today will take some pics it doesnt look that difficult but the front tubes took forever as had to make a jig to get the angles just right so everything would fit back in and work .self taught to answer your questions basically you either have the talent or you dont . ps wanted to do a good job as i Guess the guy that owns the car has a rig welding company in the tar sands in alberta

Looks good. I wish I could see some close up details of where the bars meet and the welds, but none the less it looks like it fits good. Any online literature that deals strictly with cages?

Nice work!!!!Im still learning and I cringe at welding in a car upside down on a cage.My hats off to you .I hope someday I can do the same.

What's up with the bends in the rear down bars? Is that an NHRA thing? SCCA, FIA, NASA, etc doesn't allow such a thing. Otherwise the work is really nice.

Looks nice! I will be putting a 4130 cage in my car this winter. I am happy to hear that I don't need to preheat and delay cool down, like I thought I would have to.

How did you arrive at that conclusion?? Preheat...no... but delaying cooling is what everyone is trying to make happen (by welding colder, thus slower and letting the heat build up) otherwise you gotta break out the O/A torch. Unless that's what you meant.

Looks good, I know the feeling of small cars, Ive done one in a fiero of all things and an RX-7. This past week I was doing a funny car cage(25.5 update) in a mustang and was thinking man I cant wait for the holidays to be over cause I can barely breathe all balled up in this car..........

I was wondering the same thing.

Like i said its what the customer wanted so he could maintain his interior panels etc.. . Not sure where the other guy got the info about preheat and post heat though as never mentioned anything about that ?
