JonMack Posted January 1, 2009 Report Share Posted January 1, 2009 (edited) Why can't you make a 74Kingz type tensioner for it? All you need is a big L bracket bolted through the hub bolt, a hacksaw blade to a smaller L bracket with a jockey wheel attached to it. 74K'z don't use a mech hanger.

Muel Posted January 2, 2009 Report Share Posted January 2, 2009 Just a comment from reading that thread, how is it hard to make an oval hole? Just drill too then file the middle out surely?It's a good tensioner, I'd imagine it would be pretty good at resisting knocks, but it could be much less effort to look after if you could easily tension it, or if it had a spring with an arm, then it could do all the work for you.

3dd Posted January 2, 2009 Report Share Posted January 2, 2009 (edited) It's not realy a homemade, but half of 74kingz, half of dmr's, works very well, bashed few times already, still works great. But the bolt in the 74's has to be realy tight! I definetly recommend it! I stole an idea of (i think it was) Stan Shaw and Ali C. Need to get a copyrights...

NVWOCI WVS Posted January 2, 2009 Report Share Posted January 2, 2009 you took the worst part from each tensioner and stuck them together?Sprung tensioner with a jockey wheel is the best bet, and you've created the opposite. Quote Link to comment Share on other sites More sharing options...

Adam-Griffin Posted January 5, 2009 Report Share Posted January 5, 2009 (edited) Basiacally just a Vee caliper bolted onto the Axel with a jockey wheel attached, need's tweaking but it got dark (hence the shite pics ) It's also got a spring clamped with a bolt where the pad would sit which pully up towards the dropouts.Only problem is the bar the jockey wheel is sat on is far too long and needs cutting down.Excuse the shit pictures, only had a phone handy Edit: i've just realised how long it looks, i am going to shorten it/bend it so it doesnt stick out quite so much.

Bionic Balls Posted January 5, 2009 Report Share Posted January 5, 2009 oh my..oh dear...it's a really nice idea...and well done and all..but it just sits far too vertical to be safe! It is waaay more likely to skip out of gear, and sprocket wear will be worse...you need a longer arm to push the chain down further away from the sprocket..or two jockey wheels...still..nice Quote Link to comment Share on other sites More sharing options...
N.Wood Posted January 5, 2009 Report Share Posted January 5, 2009 Surely you can take a link out of that chain?!I'd be real suprised if that doesn't skip like shit. Pretty ingenious though Quote Link to comment Share on other sites More sharing options...

Pretty ingenious thoughI could take a link out of the chain but that'd be too simple And my chain tool wont work with it I'd imagine it will skip as it is although i'm planning on fixing another jockey wheel so i get a healithier amount of chain wrap, tarty advise 2 wheels with 15t and under, thats a 13 ....After looking at the pictures i realise it sits far too vertical, i'm planning on either Bending the arm so it's closer the the chain stay or Cutting it in half and removing some links It's just temperory until my chain tugs arrive, if i can manage to make something that actually works properly i may keep it just for the crack of it, just got bored and decided to have a fiddle really Didn't help that i had no garage to use so no drills, saws etc, just bits and pieces that i could find Thanks for the comments Edited January 5, 2009 by ™Adam-Griffin™ Quote Link to comment Share on other sites More sharing options...
Damon W Posted January 5, 2009 Report Share Posted January 5, 2009 major update and bumpage, i made a new one same style as the one steve put up. ive only got pics of it off the bike as my bike didnt like it at all, my gay ass dropout has a really gay knob that bends it into the spokes. but im sure it would fit someone elses bike really well...anyhow... (it has similar tension to my rohlof )make me one? Here's mine, still working after 9months.....Just rubbing it in abit Adamwhat v adaptors are those?

casualjoe Posted January 5, 2009 Report Share Posted January 5, 2009 This one has been going strong for about a year now, tension is awesome thanks to a really thick saw blade. The block is made from hardwood and lets the spring bend around it. Spring is attached to the block by a long bolt with countersunk spacer and nut. Jubilee clip is rock solid and stainless.Wheel removal is real easy too, saw blade just swings out the way of the chain. Quote Link to comment Share on other sites More sharing options...
Adam-Griffin Posted January 6, 2009 Report Share Posted January 6, 2009 Attempt Number 2.....Much easier than the last one, plus it works which is a bonus Quote Link to comment Share on other sites More sharing options...
Skoze Posted January 6, 2009 Report Share Posted January 6, 2009 Attempt 2 is much better, Adam!Just try and keep it as out of the way as possible and you'll be onto a winner.Scholng as it works Quote Link to comment Share on other sites More sharing options...
trials_pimp Posted January 6, 2009 Report Share Posted January 6, 2009 Thats an Abortion.You dont need a tensioner, you have Horizontal Drop outs.Even if you do need one, why bother trying to make one fromthe remains of a car Crash?Stop trying to re-invent the wheel, and look at what works. The best tensioners are simple, clean and compact. Quote Link to comment Share on other sites More sharing options...

Adam-Griffin Posted January 6, 2009 Report Share Posted January 6, 2009 I thought you had/were getting some of the actual Ciguena dropout/tugs?As did i, when they arrived from BT, they'd basically just sent me the bit that goes on the end, nothing else I emailed them to let them know i needed the whole thing, and was willing to pay for it but they havn't got back to me Quote Link to comment Share on other sites More sharing options...
