Radfax Posted June 5, 2007 Report Share Posted June 5, 2007 Right! I am currently very poor and i am looking at getting back into trials on a budget, I have been talking to Spodle and i have been offered his KOT MS2, echo forks, echo stem, brand new viz bars and FSA headset for a bargain price! Anyway, the frame has had the rear HS33 mounts cut off and smothed over as he was running a rear disc and did not need these mounts. here is my problem... i have got a Chris King classic rear hub which you will all know is not disc compatable, considering to re-shell the hub is out of the question and i am VERY against selling the rear hub. i also ate rear disc bikes, i used to have a equip pro or something with rear disc.... and i hated it! So how would i go about getting some new mounts fitted? what should i do, i can weld mig, and tig but i have never tried ARC. when i wanted to do this to my old Megaslow i was told i had to braze them on, brazing costs to much for me and trying to find a half decent brazer is.... well, hard! I have some shite old frames lying abaout which i suppose i could cut the mounts off of but erm can anybody help me out?Thanks a lot, Radfax Quote Link to comment Share on other sites More sharing options...
King C Posted June 5, 2007 Report Share Posted June 5, 2007 Why do you "have to braze" them on?To my knowledge the only advantage of brazing is that it looks neater and you can get into tighter places.Im assuming you've seen theseWith the old frame thing Im sure you could just cut a section off around the mounts and weld that to the frame. Cut out a section like this and weld that to the frame.Just make sure you align everything. Quote Link to comment Share on other sites More sharing options...
dave85 Posted June 5, 2007 Report Share Posted June 5, 2007 Make some mounts from alloy plate, they're not a hard thing to get right. Tig them in, I can't help you with filler rod types but tig will do the best job. Quote Link to comment Share on other sites More sharing options...
Radfax Posted June 5, 2007 Author Report Share Posted June 5, 2007 Thanks for that king! them plates which you have pictures, are they avalible on the market to buy? the frame i am thinking of taking the mounts off of is a reefer and they have nice big juicy blocks behind them so give a bit of leaniance with making mistakes! Are you saying that i could use my mig welder to fir these mounts dave! Quote Link to comment Share on other sites More sharing options...
King C Posted June 5, 2007 Report Share Posted June 5, 2007 (edited) they're from CRC. I'll find you a link.EDIT:here palAlthough, they do seem abit flimsy. Not sure how well they'll hold up.Also it says its a braze on kit. Anyone want to shed any light on why they should be brazed instead of welded?

Walleee Posted June 5, 2007 Report Share Posted June 5, 2007 Are those frame's heat treated? If so I'd not do it personally, does the welding not weaken the metal in the surounding area unless you can get it heat treated again? I'd guess he's allready cracked it if he's had plates put in, so even with the heat treatment, they arn't that strong apparently??Not a materials expert but i think it goes something like that.

Radfax Posted June 5, 2007 Author Report Share Posted June 5, 2007 (edited) yeh some thing like that jake, but i will get the whole frame heat treated before i paint it and get riding it again. i dont expect it to last that long, just some thing to get me back going again!___EDIT___Thanks for that one King, what i think i am going to do is.... cut my mounts off of my mission haha as the threads are all ok ect and weld them on, they have a bit of juice behind them aswell so i think they should hold up alright! Now its time to do some thing diffrent, I am thinking of having the mounts on the underside of the frame... not to sure yet ill see how it goes... Thanks lads!!!

King C Posted June 5, 2007 Report Share Posted June 5, 2007 (edited) Yea, then you can buy my echo. Lol.Tell me how you get on. Im quite intrigued by this project.EDIT: To be honest I cant see any advantages of having reverse mounts on the frame other than hose/maggie protection.Surely they'd be harder to set up and secondly the wheel rotates into the top of the frame and so having the brakes on the underside will put stress in the mounts and will be effectively pulling your beautiful mounts off the frame. Whereas if they were put on normally the the mounts will be pushed into the frame kinda thing. Wow that was long winded Edited June 5, 2007 by kcchan Quote Link to comment Share on other sites More sharing options...
dave85 Posted June 5, 2007 Report Share Posted June 5, 2007 The braze on kit that you can get from CRC is just that, for brazing (or welding) to steel frames. Quote Link to comment Share on other sites More sharing options...
Radfax Posted June 5, 2007 Author Report Share Posted June 5, 2007 yeh i hadnt really thought about putting them on the underside but hey was just a random idea! I tihnk i might have a go myself, if i tit it up then i will just mark out where i want the mounts fitted and take it up my local fabricators.... Either eay its all kool i suppose Thanks laddioes Quote Link to comment Share on other sites More sharing options...
Christophe' Posted June 5, 2007 Report Share Posted June 5, 2007 The braze on kit that you can get from CRC is just that, for brazing (or welding) to steel frames.listen to him!And they aint flimsey! Quote Link to comment Share on other sites More sharing options...
RobinJI Posted June 5, 2007 Report Share Posted June 5, 2007 Erm.. yeah, have you not thought about the way a KOT is alloy? as in it'll need TIG welding most probably, and you will need alloy mounts to weld on. So the ones from the reefer should do the job nicely, but I'd take it to a local alloy welder if I was you really, alloys not easy to weld, and it'd be easy to cock up the frame majorly.Also mounts under the frame kick ass haha, because like kcchan says, they pull the break open when the wheels rotating forwards, so when you hang off an edge like when getting up stuff or most gaping, you get more breaking power, as the wheels trying to rotate backwards, and to be honest, that's when you need the full power, not when you're slowing down. On top of which, they look pimp. haha. Quote Link to comment Share on other sites More sharing options...
powerz Posted June 6, 2007 Report Share Posted June 6, 2007 (edited) I have these if they are any use to you never used em just been sitting in me box of bike bits. £4 posted Edited June 6, 2007 by powerz Quote Link to comment Share on other sites More sharing options...
Walleee Posted June 6, 2007 Report Share Posted June 6, 2007 as has allready been said those are for brazing or welding onto steel frames. His frame is not steelIf you have access to heat treatment then definately get it done without a doubt. it'll be a learning experiance if nothing else.
