i think we need to tone down the hostility in this thread... so whats everyones opinion on abortion? how good of a job obama is doing? those topics should tone it down some

 

prochoice baby! haha

and obama sucks, lets get this **** boiling!

 

well PRO-LIFE and obama is 10000x better than bush!






even though im kidding, i still feel dirty for saying that ha

 

PROCHOICE!!!!!!! i da know, obama has so much **** against him, that and i don't live in that country... doesn't look bad to me...

i hear ya, that would be my biggest fear!

 

my avatar is with stock rims and tires, now im lifted on 31's, soon to be 33's after leveling kit

 

i think i read somewhere that the 6" lip at the bottom is there so that nothing fall out and becomes a hazzard to the other vehicles around you. someone posted a vette saying that the windsheild is gonna support the weight of the car... if you roll a vette just daily driving. you've got some issues and i'm talking kelsey grammer issues (rolled viper kind).

i you really want half doors or the likes, buy a jeep or make custom ones.

 

what kind of tubing would i need to use? and welder?

 

that's really up to you to decide... i would use 1 1/2 inch 1/4 or 3/8 wall... should be strong enough imo... but i am in no way a professional welder or an engineer... i haven't done any welding for years

 

Tig or stick - mig is nice and clean but with a structural element like that you'll want complete control over the depth of your welds. If you're going to add sheet metal panels or anything decorative, mig them on if you want after you tig or stick weld the frame structure IMO

 

****, he's not gonna be making them out of solid 1" bar stock, he doesn't NEED a stick welder. Sure TIGs make nice strong welds but a MIG will male MORE than strong enough welds for tube doors. Entire buggies, link pockets and brackets on axles and frames are all held together using MIG welders.

 

seeing as it sounds like he is going to need to rent, beg, borrow, or steal a welder anyway - I don't see why he wouldn't tig or stick it. Either tig or stick offer you a lot more control over the penetration of your weld than mig. Plus, I'm figuring he is probably going to be dealing with portable units, and there are a ton of little migs out there that you can cart around and plug into a wall outlet that simply don't have the juice to get down good and deep into thick walled pipe (especially at the hands of someone who doesn't do much welding. It's pretty easy to lay a mig bead down that looks good even if it didn't go very deep - if your tig weld isn't deep enough it'll look off, and if your stick bead isn't deep enough it'll just be a sloppy mess). IMO, get a tig or a stick and don't worry about your welds cracking. If you have access to a big hardwired mig unit or at least something plugged into 220, go for it with the mig...but if he had that access I'm guessing he wouldn't have asked what kind of welder to use.

 

i agree with matt... as long as you get a welder rated for the metal you are welding (which you should be doing with a mig, tig or stick) it's going to be just fine, most mig welders that run on 120 will do 3/8" wall... you can rent them from places like home depot... the one i borrowed when i used to work there was strong... just turn your wire speed down and your heat up...

if you weld this thing up and you can't bend or break it with some force in your hands, (while it's off the truck) by means of dropping it on the corner or something, it will be fine...

i've made tonnes of structural items using a 120 mig, i think the one i used was a miller... but i've also had things epicly fail using a 120 lincoln... it depends on the brand and quality... check the specs of the welder, don't use something that is below spec for your material...

 

Hey to each their own. A 120 MIG will most likely be rated at up to 3/8" wall, maybe up to 1/2" - either way, you'll be pretty close to max capacity. I've done a fair bit of fabricating myself, including two tube frames for manned electric race cars. I've done welds on 3/8" wall pipe with MIGs rated for it, put those welded pipes in a vice for a test and been very disspointed with the penetration I got.

For my money, if I were building something I was hoping would keep me in my truck (and other things out) and provide some structural support in the event of a crash or roll, I'd go with TIG. Rent 6' of extra pipe, cut it into 4" lengths and pactice welding them into 90* elbows. You have complete control over how much purchase your weld gets in each object you are welding (indipendantly from one another, which is nice if you want to do something with a couple different thicknesses), and when you're done with a good tig weld on a tick pipe, the weld will be the last thing to break instead of the first. Roll the door on a rock, and you can bet it will bend instead of breaking at the weld and sending pipe ends jutting into the cab.

Just my $.02 - I love my little miller MIG and use it just about every week. I used it to make the mag lite mount for you truck, just personally I wouldn't use it to make my doors.

 

I love people that are like "oh you gotta do it one way or its wrong"

All I'm saying is my whole truck was held together with a MIG welder, and lots of people I wheel with use MIGs. I beat the living **** out of it and nothing broke, except the trac bar bracket and I know that was a ****ty weld.. after I fixed it I never had another issue.

IF YOU DON'T KNOW HOW TO WELD YOU, NOTHING IS GONNA HOLD TOGETHER! plain and simple, if you can MIG it'll hold. again, they're JUST tube doors, nothing structural.. hell he could oxy torch weld it.

 

jeeps have roll cages built in so that makes them able to go doorless. if it wasn't a pain to align the doors back up i would do it lol

 

Not sure where I said "oh you gotta do it one way or its wrong" - I said for my money I'd tig it...you said for yours mig would be fine. I'm not sure what the huge issue is here - if you guys have done some welding I assume we can agree that he'll get better penetration with a TIG. It's not like he has a mig on hand and I'm saying he should bring it to the dump and go rent a tig - he has to go rent something anyway...what are your reasons for NOT tig welding it?

I get that you think MIG will be fine...and sure it probably will be as long as he doesn't wrench the snot out of it rolling or something - but if he has to go out and get something anyway why not get a TIG and bury some nice deep welds in there? I'm not trying to pick a fight here, I'm asking seriously - if you had a choice between MIG or TIG on fairly thick walled material, and you had equal access to either welder, why WOULDN"T you choose the TIG?

 

just get some old doors from a junkyard and chop them into half doors

 

wait i can rent a welder? that would be a whole lot easier...i've welded with oxy acetalene b4, but it was an exhaust so it was pretty thin, but it held up. anyway, how much tubing do you think i would need?

 

get your door, cut it up... lay it on a piece of cardboard, trace it all out, choose your size of tubing, and draw it all in... measure how long your lines are, add 10% for an oh **** factor

 

loooolll

 

i'm being serious...

 

yea so am I.. and there is nothing wrong with MIG welding. you must not know what you're doing.

sure if I had a **** load of money I would LOVEE to have a fancy water cooled TIG welder, but I don't. and I KNOW a MIG welder is more than sufficient.. and unless you completely suck at welding it WILL be more than strong enough for anything he'll be doing.

 

Look man, THIS GUY NEEDS TO RENT A MACHINE EITHER WAY. We're not talking about your personal case here, he has equal access to a MIG or a TIG - and a TIG produces a superior quality weld. Honestly what are you arguing about? If you came down on the MIG produces a better weld side of the fence I'd get it - but you seem to agree that TIG produces a better weld. It isn't going to cost this guy more money to TIG his doors. It will take him an extra 30mins to learn the TIG vs. the MIG, and when he is done he will have knowledge of a much more versitile welding technique. A big MIG can lay a deep weld down as good as anything, but the little portable 1 phase units we are talking about only penetrate so deep.

Edit: Conversation actually reminded me I need to buy some nozzles for my little miller MIG, which got me onto their site. Their 1 phase MIGs are advertised for up to "light fabrication" (their 3 phase machines are advertised for "fabrication"). Their smallest TIG machine, also a little portable unit, is advertised for "automotive" and "4X4/offroad" fabricating. You should probably e-mail them to let them know that they forgot to include those things on the list of what their small MIG can do.

 

oh, i thought you were laughing at my cardboard door tracing idea...

look, reject... you have been on this site how long? and already you have been in how many arguments? back off and shut the hell up, i'm sure i'm not the only one on here who is tired of listening to this diarrhea that's coming out of your mouth... you are NOT going to find a mig welder to rent for anywhere near the cost that he could find a mig to rent that will do what he needs to do... i've said it once, i'll say it again... i'm not going to sit here and argue with some little e-thug who thinks he's hot ****. shut the hell up!
