David Posted April 30, 2007 Report Share Posted April 30, 2007 (edited) After many many many hours of work I finally have something that resembles a frame! It it NOWHERE near perfect at all but I am pleased with what I have managed to do. Its full T45 tubing, 395 chainstays, 1040 wheelbase, +10mm bb rise. I was originally going to braze it but didnt have the facilities but managed to borrow a MIG welder from someone. I have never welded before so the welds are nasty to say the least! Seems to be pretty strong. I started to build it up but I have realised a fundemental flaw as my cranks are interfering with the chainstays Im using a 127.5mm bb axle aswell so I cant see an easy solution to this Ah well its been a MASSIVE learning curve. I have learnt so many new skills and techniques. If you are considering making one you have to be prepared to put A LOT of time into it and you will get very frustrated throughout building it. A big thanks to TODGE and IOLO for answering many questions. Obviously it is not painted yet and missing cable guides (Also need to file the welds down)A few pics (Not very good) :Thanks for looking,Dave Edited April 30, 2007 by David Quote Link to comment Share on other sites More sharing options...
Bill_B Posted April 30, 2007 Report Share Posted April 30, 2007 (edited) looks nice IMHO (similar design to what I would do if I could, especially with respect to the seatstays location on the top tube), yes your welds are a bit rough (almost as bad as some of my stuff ) but a bit of careful work with a grinder and you could tidy those up. A good choice of paint finish could also hide the rougher parts (IMHO matt black and some brighter graphics to draw the eye away from the welds).do the cranks hit the chainstays at both sides? could you grind away a section of chainstay and plate it?

Fishy Posted April 30, 2007 Report Share Posted April 30, 2007 Looks really good for your first ever one. Can you get pictures of the welds? Quote Link to comment Share on other sites More sharing options...

IOLO Posted April 30, 2007 Report Share Posted April 30, 2007 thats ok that is !!be proud david, great for a first ever go !!well done !iolo. Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted April 30, 2007 Report Share Posted April 30, 2007 yeah for a first frame thats fricking MINT! I really like it! Even if it doesn't look as "tidy" as normal, that fact that youre a "normal" person and not a company makes it so much nicer to look at for some weird reasonnice one Quote Link to comment Share on other sites More sharing options...
craigjames Posted April 30, 2007 Report Share Posted April 30, 2007 fair shouts!! nie one, looks pretty nice, smooth out the welds give a good few licks of paint and it'll be all good fun just out of curiosity where did you get the tubing as im looking to build my own frame but want to use decent tubing. did you make your own jig? just a quick side note i can tig weld but not fillet braze too well, what are the downsides of tig welding a steel frame?one again congrats on a great first effort craig Quote Link to comment Share on other sites More sharing options...
David Posted April 30, 2007 Author Report Share Posted April 30, 2007 Ill put more info/pics up when I get time. I think im going to paint it a grey colour...I'd prefer to keep it a darker colour, think it will look loads better once painted. Just got to get hold of some paint now.

dave85 Posted April 30, 2007 Report Share Posted April 30, 2007 The crank thing is quite common, if the old steel Megamos had been built with straight chainstays, they'd have the same problem. Megamo put a kink in the tube to clear the cranks, perhaps make a pair of dies up to put an s-bend in the tube? Quote Link to comment Share on other sites More sharing options...
David Posted May 1, 2007 Author Report Share Posted May 1, 2007 I have thought about cutting a slot and plating the chainstay but I think I might cut the welds at the CS/BB area and move them inwards are there on the outer edge of the BB shell at the moment. I dont think tyre clearance will be a problem as I have massive clearance atm. Quote Link to comment Share on other sites More sharing options...
darrenhopper Posted May 1, 2007 Report Share Posted May 1, 2007 Perhaps make a pair of dies up to put an s-bend in the tube?I second that. If you've got a steel workbench or a large plate you could weld a couple of short bits of round bar either side of the frame and bend in the S under some heat. Just so long as there's still enough tire clearance.Smashing job though, I really like the shape you've gone for. Quote Link to comment Share on other sites More sharing options...

Just got to get hold of some paint now.Have you considered getting it powder coated instead of paint, I found a local place that would do a frame for £30, if you want a simple colour you will get a very good hardwearing finish, and its not that expensive compared to primer and paint.

I have however decided not to paint it atm and wait until its been marked and then powder coat it =)Thanks for all the comments!Dave Quote Link to comment Share on other sites More sharing options...

A – TIG welding creates a much stiffer joint, this means the joint cannot take as much stress as a more flexible fillet brazed joint. Also the larger curve provided by fillet brazing allows stresses to be transferred much better. Also though fillet brazing is used, the frames are still incredibly stiff.

NVWOCI WVS Posted May 1, 2007 Report Share Posted May 1, 2007 good effort, really impressed!how did you find the building part? do you have a frame jig and stuff? i want to do the same for my project next year, in the very early stages of designing at the moment...got any tips/advice? what brazing equipment did you use?dont want to steal your topic because i've already got my own but heres a pic of my cad model if yo're interested? any acvice on improving the design etc?cheers Quote Link to comment Share on other sites More sharing options...

2sixstreet Posted May 3, 2007 Report Share Posted May 3, 2007 I would suggest modelling up BB and cranks and adjusting the stays for clearance. Quote Link to comment Share on other sites More sharing options...
Waynio Posted May 3, 2007 Report Share Posted May 3, 2007 good job i wish i had the possibilities to do something like this in D&T/Resistance materials at skool. good show!!!!Waynio........................ Quote Link to comment Share on other sites More sharing options...
toyota200x Posted May 3, 2007 Report Share Posted May 3, 2007 That frame looks awesome. I would defiantly ride it. Best of luck with the cranks / Chain stay problem. Keep us updated. Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted May 3, 2007 Report Share Posted May 3, 2007 (edited) If you're making a frame and are having trouble with clearance just use an 85 or 100mm bottom bracket shell. Edited May 3, 2007 by ScotchDave Quote Link to comment Share on other sites More sharing options...
