nice welding!

I would be interested in a picture of your bending machine, and the mandrel dies etc. Do you just have the mandrels for roll cage tube or a whole range of sizes? These machines can cost heaps.

What car is that in?

some great work there! good to see more people getting into this kinda thing :thumbup:
how much do you charge? and where are you?

[roco]

thanks guys, im based in ireland so i doubt id be any good to you guys, just thaught youd like to see as i see people asking for cage pics and info.

its a jd2 manual benders, i only have two dies at the moment, 1 1/2 and 1 7/8. main sizes in tube for cages. you can get all size dies, dies for square too. but at 350-450 us dollars each itll be a while till i can get a few more.

the car is a 1992 honda eg civic. track beater.

quite simmilar in design to the cage we made, we use a manual mandril aimed to get it close as possible, simmilar floor plate designs too.

also to stop the pittin in the welds i noticed, we get a spare tank of gas, and run a line to the inside of the tube, works especially well with stainless.

where do you get a bender that can do 1-3/4inch ??

[driftke70]

states

[Anthony]

not your garage? damn. :)

[Anthony]

so a JD2 plus the 2 dies you need is around $1000US plus shipping. Is this similar to the deal you got beally?

[driftke70]

yeah me and my bro went halvies, cause i wanted to make my cage, and he wanted to make a buggy to race aus safari,

we got a setup, was around 3500 ish, we have 4 dies, and we ordered dimple dies at the same time, so it would have been around 2000 ish for the bender and 2 dies, and we just made a little stand for it to bolt to the floor, works pretty darn well, oh yeah we also bought a fish mouthing tool, which comes in handy ALOT.

[roco]

yeah thats prety much the same setup i got beally. what wlder are you using? mig tig??. ive never had to purge the inside with mig, but its necessary with tig.
plus i find the better you prep the surface the better the weld.

[driftke70]

half mig half tig, use tig on the single joins, use mig on the floor plates and stuff where good penetration is handy, takes a bit of thought, with the fish mouthing tool you can get stuff to fit so snug so the tig works awesome, but with the mig you almost want a 1mm gap.

better surface definitely helps, almost necessary, sometimes when you are doing the last weld sealing something up, the air on the inside heats up and tries to spit out through what your welding,

i still have to mount my seats before i do my cross bars so they are in a good spot,
