Luke Rainbird Posted September 26, 2010 Report Share Posted September 26, 2010 Siiiiick! Steel + carbon is a bit of an interesting one, but hope it works out well for you! Did you stick with the short/high geo in the end? 1 Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted September 26, 2010 Author Report Share Posted September 26, 2010 Looks awesome now it's coming together can i ask why you chose to try a carbon top tube, was it just because you could? well, i just wanted to have a play with it really, thought it would be something out of the norm . Siiiiick! Steel + carbon is a bit of an interesting one, but hope it works out well for you! Did you stick with the short/high geo in the end? I went down to +50, had a look with it lower and it just didnt look like what i had in my head if you get what i mean. It'll either be rather nice and flicky, or just cramped and a bit rigid, so we'll see what happens . Cheers, Josh. Quote Link to comment Share on other sites More sharing options...
the trials mop Posted September 27, 2010 Report Share Posted September 27, 2010 No I meant bronze weld it. apologies, what is the difference out of curiosity? Quote Link to comment Share on other sites More sharing options...
Krisboats Posted September 27, 2010 Report Share Posted September 27, 2010 That looks very smart mate. I'm really very impressed by the headtube, looks fantastically original. Can't wait to see it in the flesh. Just curious by the way, are you aiming for a specific weight once its finished? Seems like a fairly unique competition styled bike so was wondering if you were factoring the same competition style weight into it? Quote Link to comment Share on other sites More sharing options...

Seems like a fairly unique competition styled bike so was wondering if you were factoring the same competition style weight into it? Nah, not really, under 2kg would be nice just fancied something a bit flowy rather than straight lines all over the place When its finished, and if it works, fancy making another for a paying customer? I'd love some carbon tubing. Would love to, have come up with some more ideas, will have to have a play with them first like, have a go when we see each other next, see what you think . Cheers, Josh.

Matt Vandart Posted September 27, 2010 Report Share Posted September 27, 2010 (edited) The Araldite worries me... Otherwise a very professional looking project! Araldite for the win. apologies, what is the difference out of curiosity? Brazing: the filler metal (the bronze alloy) is drawn into a tight fitting joint by capillary action Bronze welding: The filler metal is deposited not using capillary action This forms a joint that is extremely strong in shear, if the joint is designed correctly. The main advantage is that the base metal is not melted and as long as the weld is done properly, you will not get cracking associated with trials frames as there is NO heat affected zone, the main cause of cracking in applications such as this. Also repair is very easy if u do f**k the weld up and it does crack. No offense meant to the original poster but I would definitely have bronze welded this frame, but then again if you do not keep doing it, it is a skill very easily lost. Also if he had not liked the way it ends up it would be much easier to alter the frame. Edit: by the way I love this frame, well done dude, cant wait to see it finished.

murph82 Posted September 27, 2010 Report Share Posted September 27, 2010 That looks the shit! Kind of looks like it needs a bit of bracing round the bb, seat tube, chainstay area, sure it will be strong enough but just looks like its a bit thin. Top effort though mate, how much do you think its costing including your labour if you had to pay for it? keep up the good work! Quote Link to comment Share on other sites More sharing options...

Probably looking at around 200-220, 140 for materials and a good few hours work, think that sounds about right . New pics up you'll!!! Josh.

Paperclip Posted September 27, 2010 Report Share Posted September 27, 2010 Like. Looks like it's going too die around the BB area though :/ Get some brakes and paint on there soon XD Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 27, 2010 Report Share Posted September 27, 2010 Nicely done in terms of the actual build, but something about the proportions of it looks sorta... skewed. Just the larger gap by the Kamel-esque bit at the headtube, then the super small and compact mid-section. It just doesn't look 'right' in my head.

Rob Leech Posted September 27, 2010 Author Report Share Posted September 27, 2010 Like. Looks like it's going too die around the BB area though :/ Get some brakes and paint on there soon XD I'll get some better pics up of it tommorow, but i can asure you, that'll be the last place it'd die . Gona sort out the whole brake mounts/booster tommorow, will try and get some riding pics out before the end of the week . Oh, and forgot to put in the first post, the glue is simply awesome, when the frame was still in assembly you could quite easily press the top and bottom tubes about 10mm closer together. With the glue, no movement at all, very impressed with it. Cheers, Josh. Quote Link to comment Share on other sites More sharing options...
RossMcd Posted September 27, 2010 Report Share Posted September 27, 2010 it looks as if the seatstays may be a bit too low... does the chain hit them at all? And it needs a seat tube. Or the frame will just end up folding. Other than that very good attempt! Well done. Quote Link to comment Share on other sites More sharing options...
Shaun H Posted September 27, 2010 Report Share Posted September 27, 2010 Siiiiick! Steel + carbon is a bit of an interesting one, but hope it works out well for you! Watch out for turbo corrosion on the steel, carbon fibre can cause even aluminium to corrode badly without galvanic protection. The epoxy may insulate it enough though. Awesome project anyhow, can't get much more standover clearance than that! Quote Link to comment Share on other sites More sharing options...

Electrolysis ( I think ), hopefully the glue will stop it from making overall contact like. Lol, its very strange sitting down on it with the dip there.

Well done. Yeah, i have had a problem with the seat stays, but has been resolved now. There is a seat tube, its just a bit small, not much space down there . Cheers, Josh.

monkeyseemonkeydo Posted September 28, 2010 Report Share Posted September 28, 2010 Please tell me there's a seat-tube of sorts in there somewhere?... Otherwise I can see it being kinda noisy to ride as the toptube clangs against the downtube everytime you do anything! Quote Link to comment Share on other sites More sharing options...

Skoze Posted September 28, 2010 Report Share Posted September 28, 2010 Love the idea (and it's so good to see someone getting off their arse and doing something!) not to keen on the overall look of it though. If it wasn't so madly low i think i'd really really like iT! Major respect for doing it. Quote Link to comment Share on other sites More sharing options...

What, you've glued it together.........scared Looks very professional though mate, would confuse the hell outta non trials riders, push it dude, make buggers and earn yourself some £'s, you seem to have done that in a week! gotta be plenty of people willing to pay £500 for a frame you could build to there specification?!

What, you've glued it together.........scared :unsure: Composite generally are bonded to other materials of a different type, I wouldn't worry about it if it's all done correctly. It's how they did the Koxx Karbon. Quote Link to comment Share on other sites More sharing options...
