casualjoe Posted February 13, 2014 Report Share Posted February 13, 2014 I'm about 1/4 way through roughing up the area to be repaired, there is a crack around the bottom of the seatpost and it turns out to be quite a tricky area to fix.. I'm thinking maybe wrap the tape around the bb area then try and support the bit where the downtube and seatpost meet, and just wrap it really tight? After a recent mishap I have realised that the carbon tape is so strong it will crack the rest of the frame, so I wanna try and keep most of the wrap tightly around the join I think. Do you think it wlil work? wish me luck. Quote Link to comment Share on other sites More sharing options...
aener Posted February 13, 2014 Report Share Posted February 13, 2014 "wip" as in a "WIP Bikes" WIP? If it is, it's made of steel so just weld it. It will be far better in the long run. Quote Link to comment Share on other sites More sharing options...
casualjoe Posted February 13, 2014 Author Report Share Posted February 13, 2014 I get it welded and it keeps on cracking, it's quite thin tubing,. and yes the one and only W.I.P Quote Link to comment Share on other sites More sharing options...
casualjoe Posted February 13, 2014 Author Report Share Posted February 13, 2014 (edited) I don't know much about welding, maybe a pro welder on here could do a better job than my local welders ha.

N.Wood Posted February 13, 2014 Report Share Posted February 13, 2014 Worth a try Joe! See what happens. Quote Link to comment Share on other sites More sharing options...
casualjoe Posted February 13, 2014 Author Report Share Posted February 13, 2014 Might as well brav, I've done a dry run with the tape and there's a way of doing a dope wrap, it's probably gonna break the frame somehow though. Quote Link to comment Share on other sites More sharing options...
casualjoe Posted February 15, 2014 Author Report Share Posted February 15, 2014 Well after scratching the shizer out of it with a file.. I wrapped the tape around the join as practiced, it came out a bit messier than I had hoped but the main thing is that it holds.. I'm going to build this up tomorrow, it does ride nice and the rest of the frame is really quite good. Excited to ride my old frame again woohoo! any (educated) bets on how long it'll last?

Martin Reynolds Posted February 15, 2014 Report Share Posted February 15, 2014 Not hard to use a mig, especially on clean, thick metal. If i was you i'd have had a bash at welding it before wrapping it. 1 Quote Link to comment Share on other sites More sharing options...
Blake Posted February 15, 2014 Report Share Posted February 15, 2014 No idea! I don't understand why it's cracked so quickly after welding again. What tubing is it? Quote Link to comment Share on other sites More sharing options...
casualjoe Posted February 15, 2014 Author Report Share Posted February 15, 2014 (edited) It's reynolds 531 I think. Just to clarify, it has been welded again but I know it's just gonna crack again, the seatpost is thinnn. I'm going to say 2 rides.

zetecmk2 Posted February 15, 2014 Report Share Posted February 15, 2014 thin...but thicker than most car panels! can be welded again! it'd look better too! Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted February 15, 2014 Report Share Posted February 15, 2014 It's a freakin' WIP, of course it cracked again. Quote Link to comment Share on other sites More sharing options...
aleksander lakselv Posted February 17, 2014 Report Share Posted February 17, 2014 (edited) Ask your welder to add some steel gussets. Edited February 17, 2014 by aleksander lakselv Quote Link to comment Share on other sites More sharing options...
craigjames Posted February 19, 2014 Report Share Posted February 19, 2014 (edited) Seemed to hold up pretty well last night Joe, you looked like you were enjoying being back on it! Think you could add a few gussets, but the tubing is so thin I think you'd end up with cracks anyway; you'd just move where they are.

casualjoe Posted February 20, 2014 Author Report Share Posted February 20, 2014 (edited) Alright, a gusset or two sounds like a good idea. I'm going to copy the style of gusset already on the headtube/downtube join and get them welded on by a different welder. Got a rough idea where to put them but never done this sort of thing before. This is after cutting off that bodge first obviously, I will be interested to see how well it's stuck after a few rides.
