mud-magnet 07-10-2002, 09:28 AM ok, i'm going to build my traction bar pretty soon, and i'm thinking of 1" box tubing....... will it be strong enough, or should i go with 1.5"?????? i know, kinda newbie-ish type question eh???:flipoff2: :flipoff2: :flipoff2: :flipoff2: okcrawler 07-10-2002, 10:41 AM 1" would be weak. Most of the traction bars I've seen fail, do so after being bashed on the rocks a few times. Once they are tweaked, the ladder structure collapses. :( Over design it, if there is any chance of it getting hit! ;) mud-magnet 07-10-2002, 11:13 AM so would i be better off with 1.5" tubing???? i will be putting atleast 2 supports in it to strengthen it up, but just woundering what size is better.... Rockrat 07-10-2002, 11:32 AM Design it like the breeze setup Ive bashed the livin shit out of mine + dragged it over Rocks and it still good as new Shrock 07-10-2002, 11:55 AM You haven't said anything about thickeness. Try 0.25" wall 1.5" square. I'd think that would be pleanty. mudlite 07-10-2002, 12:09 PM Do it right, go 1" .25 wall round. Square will not deflect as well as round. mud-magnet 07-10-2002, 01:33 PM well i'll get the thickest i can get.......... i'm thinking the square would be easiest to weld to and build than round....... but i'll see what happens........ thanks.....

First think about the design? Where's it gonna be? Up high out of the way.... Will it be triangulated and/or fabricated in any way or just a chunk of (heavy) steel bolted to you axle? Personally id go bigger cross section lighter guage.... but then agian i dont think ive welded on a piece of .25 on my zuke yet :-D does the winch plate count? Think "lead sled" -yag CSR 07-10-2002, 05:41 PM I made mine with 1" square, 3/16 thick. I've beat the hell out of it, the paint is scaped off but it's still straight.:) mudlite 07-10-2002, 06:39 PM Originally posted by Shrock care to elaborate on "deflect" any why round would be better?

I can straighten round. Ever try to straighten square? Rockrat 07-10-2002, 06:54 PM Like I said Mike do this the most Ive done is tear the zurk off of it http://4play4wheelers.com/tracbar.jpg mud-magnet 07-11-2002, 08:43 AM thanks..... i think i'm still going to use square..... i doupt i'll bend it on the stuff i do here, if i do then i'll build one with more supports......:D :D :D l8r....... and scott, i don't got the stuff to build on like that........ grinder and welder will make the square tubing one, a plasma cutter, lazer cutter, and stuff like take would be needed to make one like breeze's..... l8r:flipoff2: DemoMike 07-12-2002, 08:45 AM a plasma cutter, lazer cutter, and stuff like take would be needed to make one like breeze's..... People tend to forget about the ol' oxy-acetylene torch. A little clean up with a grinder afterwards and it can very much look like a pro. unit.:D mudlite 07-12-2002, 08:48 AM how does the Breeze one allow for side movement of the axle when articulating? UZI 9mm 07-12-2002, 10:34 AM Originally posted by mudlite how does the Breeze one allow for side movement of the axle when articulating? :confused: do you mean "unwanted" side (ie lateral) movement that occurs when really flexed up, that would potentially bind up a trac bar (if not designed properly) and interfere with articulation? or the simpler left wheel goes down/ right wheel goes up kinda articulation? am unsure about the former, but in case of the last one- the bar that bolts to the frame has a threaded hole that a rubber bushing'd shackle bolts to (allowing it to move up and down). the trac bar itself comprises two sections that allow for fore/aft movement via telescoping tube, and in addition allows for rotational movement-(left down/right up axle kinda articulation.) sorry if your question is actually more complex than i'm getting out of it? haven't had my second cup of coffee yet.:D mudlite 07-12-2002, 11:38 AM Originally posted by UZI 9mm :confused: do you mean "unwanted" side (ie lateral) movement that occurs when really flexed up, that would potentially bind up a trac bar (if not designed properly) and interfere with articulation? Yes, that one:D Like when you stuff one tire, but the other drops in an arc towards the stuffed side. If these traction bars don't have some sort of Hiem or JJ, then how do they account for this mouvement? UZI 9mm 07-12-2002, 12:03 PM Originally posted by mudlite Yes, that one:D Like when you stuff one tire, but the other drops in an arc towards the stuffed side. damn, my second cup of coffee did nothing other than make me have to pee:D i thought the "left tire down/right tire up" WAS what you mean by your above paragraph? because the sleeved tubes allow both fore and aft PLUS rotational movement in the arc you're referring to. what i had meant about the "unwanted" movement had more to do with like a panhard bar kinda thing, (ie "side" movement) but i still can't picture it clearly to understand it's application to affecting "drops in an arc" rotational articulation. :emb: :idea: could you maybe mean "arc" in a Horizontal plane versus Vertical? but wouldn't that be fairly miniscule? and even then i think the telescopic action of the tube would take care of that, though. geez i dunno. just shoot me.:rasta: mudlite 07-12-2002, 12:13 PM Originally posted by UZI 9mm :idea: could you maybe mean "arc" in a Horizontal plane versus Vertical? but wouldn't that be fairly miniscule? and even then i think the telescopic action of the tube would take care of that, though. geez i dunno. just shoot me.:rasta: miniscule, but enough movement to weaken and tear the tabs off. UZI 9mm 07-12-2002, 12:50 PM i believe there's enough give in the rubber bushing, movement in the greasable sealed sleeved tube, thickness and quality of metal, and 360*circumferential welding around the axle tube done by a professional. (not me:D )heh heh. but you'll be the first to know if i ever damage anything or something catastophic happens because of my trac bar.:flipoff2: ps- if no one has a d-shaft o.d. for you before i get back from lunch, i'll be happy to let you know- but i don't have a mic with me. will something like 75-80 mm+/_ work for you? MuddMachine 07-12-2002, 04:50 PM For the record, round tubing, pound fer pound is stronger than square :smokin: MuddMachine 07-13-2002, 10:01 PM What happened to that post that was here shrock ? Come and gone mighty quickly....... | |
