dirt jumper jake Posted March 27, 2011 Report Share Posted March 27, 2011 (edited) Yo, Finally got around to starting to put a disc mount on my maladie. with any luck it should be welded on tuesday Hopefully it should be strong enough, but we shall see. have made it in two peices as i cocked it up a bit haha, what do you lot think then?

CalopS Posted March 27, 2011 Report Share Posted March 27, 2011 (edited) I think you should re do it. Surely its best to do it properly in one piece so theres less weld and its stronger? Edited March 27, 2011 by CalopS Quote Link to comment Share on other sites More sharing options...

I want to re do it, but i dont have another frame to cut a disc mount off Quote Link to comment Share on other sites More sharing options...

mods Posted March 27, 2011 Report Share Posted March 27, 2011 Seem like a pointless idea to me. You should use a decent 4 bolt set up and you wont have a problem anyways. If you are however determined to have a rear disk then buy a frame with a rear disk and sell your current one to put towards it, welding mounts on is just gash. 1 Quote Link to comment Share on other sites More sharing options...
Bigman Posted March 27, 2011 Report Share Posted March 27, 2011 It looks like you need to lower the whole mount abit, the rotor doesn't look like it is siting fully into the caliper. Adam Quote Link to comment Share on other sites More sharing options...

Rob Leech Posted March 27, 2011 Report Share Posted March 27, 2011 Heya chap, why not look at making an adapter? I made one not too long ago that bolted to the 4 bolt mounts and to a hole that i'd drilled and tapped in the dropouts. This would mean that if you did want to go back to maggys, you could simply take the adapter off. I would recommend thinking about this first . Welding the mount to your frame will likely result in a failure of the material around the heat affected zone (ie, it will crack either on the mount you've attached or on the area around the drop outs). If you need a hand, i'd gladly draw it up for you, didnt take me long to make . Cheers, Josh. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted March 27, 2011 Report Share Posted March 27, 2011 If you're set on the idea and don't want to switch frames then I'd seriously consider the adapter idea before welding a mount on, even if you have access to heat treating and stuff afterwards. Yeah, they might be fugly but you're frame is more likely to last a ride or two that way Couldn't you sell the frame and pick up something with similar geo and a disc mount for the same sort of cash?

Het treatment would be a waste of time in this, as aluminium can't be normalised, another stage of heat treatment would acctually soften the frame . Not having a dig, just thought people would like to know, when a frames done, its done . Cheers, Josh. Quote Link to comment Share on other sites More sharing options...
6ft-midget Posted March 27, 2011 Report Share Posted March 27, 2011 Another vote for making an adaptor, and I talk form experience. The welding just completely ruins the heat treating in that area of the frame. The tab itself will probably just tear away from the frame, the exact same thing happened on the disc tab i had welded on my A2. I'd take the offer of having an adaptor drawn up for you, but that's my opinion. If you want to ruin a perfectly good frame then do continue.

Its simpsons old frame that had a snapped chainstay, ive had that rewelded and ran it brakeless for a while & managed to pick up a tech trial for £40 so its worth a shot seeing as the maggie mounts are raped, if it snaps then oh well, i'll buy a aurem or something Quote Link to comment Share on other sites More sharing options...

dirt jumper jake Posted March 27, 2011 Author Report Share Posted March 27, 2011 Made a template for another one, as dad convieniently founced some ally sheet in the workshop Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted March 27, 2011 Report Share Posted March 27, 2011 Heya chap, cant find the one i made atm, think a friend might have it, so i've done you a quick drawing . I think the one i did was just made from mild steel as i did an ally one and it didn't fair too well, but if you've got any, try doing it from 6mm ally plate and you should be fine . If you need any help with it matey, just let me know, Josh. Uploaded with ImageShack.us Quote Link to comment Share on other sites More sharing options...

isitafox Posted March 27, 2011 Report Share Posted March 27, 2011 Muel made one ages ago that I had off him to use when playing with my disc caliper but I chucked it in the end. There's a guide to making it he did in the old wiki http://wiki.trials-forum.co.uk/index.php/How_To_Make_A_Disc_Mount_Adapter Might help you a bit!

Muel Posted March 28, 2011 Report Share Posted March 28, 2011 Did you have the shitty thin ally one I had or the steel one? Thought I kept the steel one, come in useful when you need to get leverage on a caliper for removing bore caps. Quote Link to comment Share on other sites More sharing options...
isitafox Posted March 28, 2011 Report Share Posted March 28, 2011 Yeah was the steel one but got slung when I had a big clearout, didn't realise till after I'd done it either! Quote Link to comment Share on other sites More sharing options...
