Matthew_Gibson Posted June 8, 2007 Report Share Posted June 8, 2007 I have a BRAND NEW pair of Echoi lite forks being welded, as I f**king cut it about 40mm too short Made me cry inside. I just wondered if they would need heat treated after welding the back. The guy at the fabrication shop said hes going to do them. I'm just a bit gutted that I payed £70 and fort I'd f**ked them.If I cnt get em sorted right, whats the shorted they can be on a deng frame or any other with 100mm head tube. There 140mm, too short for anything? Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted June 8, 2007 Report Share Posted June 8, 2007 where are they being welded? part way up the steerer tube?as above...i'dve thought you'd be ok using a headlock..gutting anyways!adam Quote Link to comment Share on other sites More sharing options...
Greetings Posted June 8, 2007 Report Share Posted June 8, 2007 Avoid welding at all costs. Well, too late now.Simpler solution - go to a turner, have him make an extension that you hammer and glue into the steerer to extend it. Probably would have cost 2x less, would also retain the strength of the metal. I'd definitely not trust a welded steerer. It's probably the most stressed part of a bike?

Matthew_Gibson Posted June 8, 2007 Author Report Share Posted June 8, 2007 I put some insulatio0n tape round the fords a to cut them in a hurry cut the at the bottom one, and they were supose to cut at the top one! I was raging with myself. but as I have a good engneering place round the corner. (british steel wold have been best, ano there NOT steel) I went there explained to the guy, who was sceptical about it, but she says he CAN do it! I'll be going down there tmora to see his work. opefully theyll be good!Avoid welding at all costs.

I can make one up at school/get one done by the metal work guy and see how that goes. But its like what Ali C done with his bars. You did it too! I'm sure a lad on here got the welded Rob i think his name was, on a white BT Maybe that was Trials Nation. (back in the day:))Thanks!

Bionic Balls Posted June 8, 2007 Report Share Posted June 8, 2007 thing is..it has to be flat to get the headset on...less surface area of weld..so bad. as..ooo well..i remember someone extending some fatty forks by making an extension...which is nice.

Krisboats Posted June 8, 2007 Report Share Posted June 8, 2007 Yeah, i wouldn't really trust a weld on its own without having some kind of extension in place. Just welding it back together wont be as strong as having a specially lathed metal insert that goes down an inch or two into the steerer tube and sits flush with it above where you cut it.Unless he puts a smaller metal ring inside the steerer than welds into place using that i wouldn't even think about attaching a stem to it.

Matthew_Gibson Posted June 8, 2007 Author Report Share Posted June 8, 2007 He's going to shamfer the edges. If the worse come to it, ill make a piece, but that will just "slipped" in there, With plenty of lube and a hammer. well see how it goes. VERY worse case, new(er) forks! bit gutted and they are nice forks. I suppose £70 isnt bad i guess, but I have limited cash for a while. as im buying a car soon.

IOLO Posted June 8, 2007 Report Share Posted June 8, 2007 i REALLY wouldnt weld them, they WILL break.bad luck mate !ask of he can put a little tube inside as well and weld it all together,but they will still break, will last longer though.sry mateiolo.

matt rushton Posted June 8, 2007 Report Share Posted June 8, 2007 I have an idea for you.Its not the best drawing ever, but i think you can tell whats going on. If you can't well you get a lathe and turn off a peice of metal the same size as your steerer. Then bit down the post you cut a little bit extra off. 2 mm bigger than the center of your steerer. Then you make a thread on the inside of your steerer and on the outside of your new peice of turned off metal. Then drill a hole in your peice of metal the same size as the hole was on the inside of your steerer so that your starnut will go in.(Don't go all the way through your peice of metal of you will spoil your thread) Then you cover both threads in loctite and screw togather as tight as possible. Wait for the loctite to set in.Then ride.Not sure if it will work but worth a try I'd say would say it will be stronger then welding it.Matt Rushton Quote Link to comment Share on other sites More sharing options...

basher Posted June 8, 2007 Report Share Posted June 8, 2007 Use a stemlock thing or what ever they are called and then if they do break it will all stay in one piece and you won't die. Quote Link to comment Share on other sites More sharing options...
samo Posted June 8, 2007 Report Share Posted June 8, 2007 or you might be able to get a longer srew might do the trick Quote Link to comment Share on other sites More sharing options...
Greetings Posted June 8, 2007 Report Share Posted June 8, 2007 But then there is the chance of it pulling out with a thread there isnt.Matt Rushtonso you just drill it through and secure it with a boltmost steerers are pressed into the fork not welded or threaded, and they don't pull out.

chrishayton Posted June 8, 2007 Report Share Posted June 8, 2007 How long do you think they'll last? weeks? days?if you just weld them together then think more like minutes. you have to remember it wont fit through your headset as the weld will bulge out abit.either sell them to someone and get new ones or you could try the turning another piece method. it ll break though Quote Link to comment Share on other sites More sharing options...
Matthew_Gibson Posted June 9, 2007 Author Report Share Posted June 9, 2007 Well ill get a new pair, i'll just use the monty for going to work on for now.

IOLO Posted June 9, 2007 Report Share Posted June 9, 2007 WAIT ! i have it !!ages ago in an evans catologe there was....a steer tube extender !!!!was a piece of ALU the same diameter as the steer tube, but has a small end which pushed into your fork, then an allen key which expanded the small end in your fork, and locked it in there. (then you stem when on it.,or half on it)search, or ring Evansiolo. Quote Link to comment Share on other sites More sharing options...

BenLeacock™ Posted June 9, 2007 Report Share Posted June 9, 2007 You need to get them heat treaded or they will just crack with the pressure! and last a matter off weeks with out it !! Ben Quote Link to comment Share on other sites More sharing options...
0llie Posted June 10, 2007 Report Share Posted June 10, 2007 this might sound a bit silly but what you could do isuse the thread idea, then once you have threaded it in insert a long tube the same length as your steer all the way through your fork and weld it at the top and bottom and then use a thread lock.its just an idea, as you will have a weld thread and a solid tube the same length as the steer, would make it heavier but would be alot stronger than just having a weld, you could also weld where it was threaded together so would be ultra strong Quote Link to comment Share on other sites More sharing options...

darrenhopper Posted June 14, 2007 Report Share Posted June 14, 2007 What about a low profile headset? How much of the original steerer do you need in the stem clamp. Surely if you run a low Headset like this one you'll have 28mm of clamping area remaining?? Quote Link to comment Share on other sites More sharing options...
