2- i would like to powercoate it florenca yellow
3- i guess im going more show
4-i dont know about how much room i want to loose but i know that i dont care about the back seats

ps sorry if im a dick or anything im just asking questions and thanks so much for your help guys

Don't bother with the power coating. It will be near impossible anyways with a weld in cage. You'd either have to powercoat the bars (minus the ends), weld them in, and then find a matching paint for the joints or roll the whole car into the oven. Use a quality paint and it will hold up fine.

Those cages you linked to are made with EWS tubing. Don't bother. Find a more quality kit with DOM.

You really need to decide why you want this roll cage. If you build something that doesn't meet the rule set of any sanctioning body what's the point. It'll certainly make the car near unsellable in the future. If this truly just for "show" stick with the roll bar in the back.

You can't build a car that's going to be able to do all 3. There's to many different rules for each you listed. If you try to build your car for all 3 your just gonna suck at all of them. It's not realistic to build a car that can drag and rally lol. Pick one and stick to it or don't do a cage at all. Just my .02 cents.

Ok so what are th rules for each of em ?

Cool story. How is it I got roasted? Doubt anyone on here can weld with the same heat and consistency as that ROBOT.

[dirtslayer]

I weld better than any robot son!

LOL at the comment above mig welding a roll cage that isn't going to pass any type of regulations is okay though right?

[PARANOID56]

mig welding will pass 90% of all bodys of racing,
some infoNHRA requires Tig for 4130 tubing, mild steel can be mig welded
nascar i think last time i checked 40% of cages were mig weleded.

[Crazy_pilot]

With a car that runs a ~15sec 1/4 mile a cage isn't exactly a huge requirement. Unless you're upgrading your car to be significantly faster all you're actually going to do is slow it down by adding a pile of steel tubing.

The reason for getting a pro to build your cage is this: You don't know how good your welds are. They've never been tested, xray'd, ultrasounded or faced any other kind of evaluation. The pros that build cages have been doing it for years and have a huge amount of skill. You may be able to lay down a pretty looking bead, but your first sign of the weld not being strong enough is when that joint fails in a crash and that bar hits you in the face. Bad time to be regretting your choice.

Alternatively, you could weld your own cage together, go to the track, and have the tech guys laugh at you and turn you away. Now you've gone 2 steps backwards and wasted all your time and money.

At a minimum, post up some pictures of your exhaust so people here can get a measure of your welding abilities. It sounds like your dad has experience, so at least you've got a guiding hand. Cages are a long way from exhausts though.

I respect that you're trying to educate yourself and increase your skill level, but such a huge safety item is a bad place to start that.

Save yourself some hassle, some $$, and possibly your life. This map was created by rallyists in NA that have had cages fabricated, inspected, and logbooked for competition.

It's commendable to want to build your own cage, but I'd advise you to take the time and learn about fabrication and welding techniques and some of the aspects of the design and loading of a cage. It will serve you well down the road if you're a true gear head. Figure out what you really want to do with your car and then revisit the cage project down the road.

I'm a pro chassis builder and use MIG exclusively. There is not a damn thing wrong with MIG welding anything below 4130 tube.

Here is my latest SRRS chassis I'm building. These chassis take more abuse than any motor sport on earth, Taking multiple rolls at every event. Not to mention most cars range between 3500-4700 pounds. With 2000 of that being unsprung mass ripping at each end. Then there is the amount of air caught jumping and the 500-800hp that most cars are running. I'm pretty sure if my cages hold up to this abuse. I can deem a MIG'd car cage safe too.

I've MiG welded cages before. I prefer TIG but that's just personal taste. If you look at a lot of cages you would be surprised how many are MIG welded.

[REECERS]

if mig welders are too brittle then u might want to run out of every building everywhere. I welded on the dallas cowboys stadium so yea, don't go there All the prefab was mig/flux core welded (flux on the inside while gas over top, running a wire about 3 times as big as your biggest wire from a welding shop)

[PARANOID56]

i mainly prefer tig as it doesn't shoot sparks all over

Definitely. All the cages we do in house we tig. Whether is mild, dom, or moly. A lot of stuff that comes in for other work that already have a bar or cage is mig welded. Most of them don't look so great because, in my opinion at least, being really good at mig welding isn't easy. I'm much better at tig than mig and my boss is awesome at both.

You are very misinformed. Maybe you should reverse your name to say downsyndrome...

I just returned from King of the Hammers in Southern California. (look it up) MANY of the cars there were MIG welded. Including our car (finished 9th place) You're telling me they are going to fall apart due to being MIG welded!? WAKE UP! The race is 165 miles of high speed desert pounding bumps, dips, jumps as-well as the toughest rock/boulder trails in America.

Here's a pic of our car for good measure.

KOH!
Autoblog just covered it this weekend: http://www.autoblog.com/2013/02/09/a...riffin-king-o/

I need to make it out there one day. I haven't been to So Cal since I flew into San Diego for the 08 B1k. (I was a Tech Inspector for SCORE)

[illesti51]

LOL saying you cant MIG a roll cage is ridiculous. Ive worked in nascar and yes not all chassis are TIG. Specially when you get into modified and late model racing the small teams cant afford to get everything TIGed. But to the OP as stated before I would buy a prefabbed kit and just weld it together yourself. It will save you a lot in the long run because buying the metal having to get it cut to the right length then bent will probably end up costing you twice as much as the prefabbed kit alone. Either way the most important part is that your welds are nice. Lastly as far as paint goes I would defiantly put something on there or your gonna have some rust issues. Good luck to whatever you choose to do!!

[christophergill5]

Being a welder/fabricator myself, I can vouch for the strength of mig welds. As long as you do it right, it should work great. But to each his own lol
