Walleee Posted November 15, 2007 Report Share Posted November 15, 2007 It really doesn't matter, as long as they are bigger than the headset and parallel.http://www.trials-forum.co.uk/forum/index....c=73336&hl= Quote Link to comment Share on other sites More sharing options...

basher Posted November 16, 2007 Report Share Posted November 16, 2007 You making your own headset press? if so how you get that made it cost you alot and how you planing on doing the pressing bit. With a threaded bar and nuts? been thinking about trying to make one for a while. Quote Link to comment Share on other sites More sharing options...
will Posted November 16, 2007 Author Report Share Posted November 16, 2007 (edited) I work at my local college, next to my department is the engineering dept. Took about 30 minutes to turn and drill each of them on a centre lathe. It's drilled out for M12 stud, I think I will make up a couple of washers to slide over the top... Don't really like the idea of some big penny washers. Materials are free if you hadn't guessed Edited November 16, 2007 by will Quote Link to comment Share on other sites More sharing options...

BIG Drew Posted November 17, 2007 Report Share Posted November 17, 2007 Could you post up the dimensions I may have a crack myself when I get time Quote Link to comment Share on other sites More sharing options...

Bionic Balls Posted November 17, 2007 Report Share Posted November 17, 2007 someone tell me why there are so many steps!?surely you only need one Quote Link to comment Share on other sites More sharing options...
blaze_ Posted November 17, 2007 Report Share Posted November 17, 2007 (edited) Different standarts. There are 1", 1 1/8" and 1 1/4" if my memory doesn't lie.P.S. Please write down the dimensions I am interested in making one too. It is easy to get the one that I need (by simply measuring the headset from the inside), but I am too lazy Edited November 17, 2007 by blaze_ Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted November 17, 2007 Report Share Posted November 17, 2007 oh yeah! but then....all trials frames are 1 1/8th at the moment...apart from the mission? Quote Link to comment Share on other sites More sharing options...
Smallville Posted November 17, 2007 Report Share Posted November 17, 2007 Donedozeled. Topic can be closed.Make a pair that fit thoose tricky Deng headsets to, and the Chris King ones aswell. I got a Parktool headsetpress but its hard to fit thoose two headsets with it, it will press on the bearing instead of the cup. Quote Link to comment Share on other sites More sharing options...
will Posted November 17, 2007 Author Report Share Posted November 17, 2007 I'll post up the dimensions of mine tomorrow. Although the outside diameters of mtb headsets are all roughly the same, the inside diameter where the press sits varies with manufacturer I think. However the press above wouldn't be suitable to use on a king headset or similar with un-removable bearings, it would only be used on a headset where the bearings can be removed so the pressure is applied through the cups and not the bearings. I've gotta make one like that so I can install my king headset Quote Link to comment Share on other sites More sharing options...
Walleee Posted November 17, 2007 Report Share Posted November 17, 2007 why not just use two plates like 60-70mm diameter and use them against the cups all the time? There is hardly a chance of bending the cup as the force is being applied evenly around the circumference surley? Quote Link to comment Share on other sites More sharing options...
Greetings Posted November 18, 2007 Report Share Posted November 18, 2007 I used a huge vice to install a few headsets recently, worked brilliantly. It takes a while to actually get everything perfectly straight but once you manage it's dead easy. Wouldn't use it on a King headset though, it's just wrong Quote Link to comment Share on other sites More sharing options...

On the Deng headset it will not work because the bearing i futher out than the cup is. I cant se the reason to make headsets where you cant take the bearing out of the cup, is that stronger somehow? Hope does not use that system and their headsets are just as fine as the Kings. Quote Link to comment Share on other sites More sharing options...

Muel Posted November 18, 2007 Report Share Posted November 18, 2007 why not just use two plates like 60-70mm diameter and use them against the cups all the time? There is hardly a chance of bending the cup as the force is being applied evenly around the circumference surley?Because if you have a pair of really well fitting pressey bits, and the bar is really snug then it pulls them into the frame straight, if you don't then they can be slightly offset and it causes higher and lower points of tension on the bearings, which is why, when you strip down cup and cone style bearings, if they are knackered it's almost always pitted in one section of the bearing face.
