moza Posted January 5, 2007 Report Share Posted January 5, 2007 Hey, after boshing my mech it broke, so i have made one, its basically a 6mm plate of aluminium shaped to suit. i have then put a hole in for the axel bolt, one for the jocky wheel post and a slot so that the chain tension can be adjusted. it is attached to my hanger and also by the axel bolt. the jocky wheel is held on by a 10mm stainless steel bar with an M6 thread to screw it on tis allows the chain line to be adjusted left to right. It has 2 adjustments, chain line and chain tension. take a look see what you think.I am going to make a sprung one with 2 jocky wheels soon which should be better any suggestions, or comments to improve?

ogre Posted January 5, 2007 Report Share Posted January 5, 2007 write a guide? get validated + sell them en mass? that looks really good (Y)how do you adjust the tention/ what happens if you land on your chain? does it move upwards with the chain or is it like a fresh-products one?

paolo Posted January 5, 2007 Report Share Posted January 5, 2007 Spoon-RailleurI still ride it actually, I added a tail from a plastic toy dinnosaur to hold the tension, because my axle wasn't able to hold the tension alone without having to tighten it every week or so...

flas12345 Posted January 5, 2007 Report Share Posted January 5, 2007 nice one mate, you have made a good job of that, looks well made and looks like it works good too. looks a bit heavy though (dont no if it is or not). well done. Quote Link to comment Share on other sites More sharing options...
Mat Smith! Posted January 5, 2007 Report Share Posted January 5, 2007 Yer Maruice, that handy contraption is a good 'un at that!!Love it, looks sex in real life! used to be really up tight to the frame, seems to have slacked a little?Still doesn't bosh or move or 'owt, never come off when with me.Mat Quote Link to comment Share on other sites More sharing options...
moza Posted January 6, 2007 Author Report Share Posted January 6, 2007 Thats the thing that sucks. because you push it then tighten it up to tension it when you land on something using your bash the chain goes a little slacker. this is the reason i would like to make a sprung one Moza Quote Link to comment Share on other sites More sharing options...

Luke Rainbird Posted January 6, 2007 Report Share Posted January 6, 2007 Your chain also looks REALLY long.I'm fairly certain you could whip out at least 1 link from that mother... Other than that looks pretty good. Would go for a roller myself though Quote Link to comment Share on other sites More sharing options...
andyb Posted January 6, 2007 Report Share Posted January 6, 2007 Looks really good, when i bust mine might have to do something along the lines of that.How good would a cnc'ed one look. Oooh, i could have a gold tensioner too, for the ultimate in tartiness!Andy Quote Link to comment Share on other sites More sharing options...

cunnifingus Posted December 27, 2007 Report Share Posted December 27, 2007 That looks nice, but it still uses the der. hanger. I really hate derailleur hangers. I hate them, I hate them. Im always glad to see a new home made tensioner, I like the simplicity.Thats why I like this tensioner: http://www.observedtrials.net/vb/showthread.php?t=32956 <- I also like that one because its mine If I werent so lazy, and the tensioner didnt work so well the first time, Id re-do it and smooth off the corners and maybe paint it.anyways, good job Quote Link to comment Share on other sites More sharing options...
