the medford does not include dies. Which cost as much as the unit itself. the hydraulics are a must



And you missed the point about legallity of the cage. Your car runs 13's and no cage. No Problem

You run 13's and they rquire a cage for 11 second cars. You go and install a non-qualifying cage, Guess what? YOU DONT RUN, because you have a non-qualifying cage even though you arent required to have one based on your ET's

 

now your on the right track, mine is like that sept mine is air over hydrolic. i was looking for one like that but didnt come up with one. anyways to build a proper cage just to stiffen up a street car is all well and good however by just building one with out building one to anysort of spec can hurt you if you are in a crash. be very very carfull on it.

you have to learn somewhere.



i dont think anybody woke up and just had the skill you know. i always do my research before i do a job. especially one such as a roll cage. but sometimes its hard to do research when most people say "just pay someone to do it". or put you down for not knowing it already.



thanks though. if you have any tips im open.

 

Here's a relevant article: http://werkz.com/feature.php?id=18



Lists several supposedly suitable benders.

 

thanks! theres some good stuff there!

 

i know i learn new stuff every day, sorry if i come accross as putting you down, i dont mean to. as for tips make sure you use proper plates, i would recomend DOM for your first cage as it is alot easier to work with then cromally ( major brain fart cant spell sorry) as to with crome you need a cold saw to cut it or the metal becomes way to brittle. also after you weld your joints rose bud torch to a light glow and cool them slowly to naturalize the metal so its not so brittle. anyways hit me up some time on a pm and we can rap about it somemore as i am building a EP rx7 chassis now.

 

Chromoly cuts fine using normal cutting tools(bandsaw or cutting wheels), although it wears the blade quickly. Cutting fluid helps greatly with blade life. As far as the welding, chromoly tubing on aircraft is not required to be annealed after welding because it has been proven to have a minimal effect on the strength of the piece. You do need to be aware of the minimum bend radius for chromoly though, it cracks easily if you exceed it.

 

as far as i was told from a scca tech inspector i am required to normalize the welds

 

I find it hard to believe the SCCA requires normalized welds while the FAA does not. Did he show you where in the rule book you could find it?
