Neon-trials Posted September 17, 2013 Report Share Posted September 17, 2013 Amazing welding there dude! I know how hard it is to weld so that is amazing! If you want someone to try your frame, I'd be up for it, I would pay you for the frame etc of course! As soon as I'm up and running il give u a shout buddy 1 Quote Link to comment Share on other sites More sharing options...

Bionic Balls Posted September 17, 2013 Report Share Posted September 17, 2013 Very true , it's not a given yet I'm going to make ONE stainless on to get a battering as a proto and if it holds up if anyone wants one they can have one. Also I will be using the tried and tested Reynolds steel that the Leeson frames were made of . And for the record kris Leeson is a very good friend of mine and I will be talking to him and his dad soon for any experience they can offer . I did speak to kris to day and he said none if the Leeson frames were heat treated as they didn't need it with the 531 Reynolds tubing . Nothing is a certainty yet until I'm fully confident they can hold out otherwise I won't be selling any. Reynolds..good choice! I take it you work with CrMo steels too? Geeky question but do Reynolds recommend consumables to use on their tubing? Good luck! Adam Quote Link to comment Share on other sites More sharing options...

*gentlydoesit Posted September 17, 2013 Report Share Posted September 17, 2013 yes,yes i did haha u-brakes with nokon(or alligator?) hoses... does it make them real brakes? just joking bud In its day that bike owned i imported most of the parts, including the nokons, the brakes were insane!

craigjames Posted September 17, 2013 Report Share Posted September 17, 2013 Reynolds 631 is probably your best bet out of the tubesets they sell, look at the new Stanton Slackline 631 and their reasons for switching to that grade tubing.

The Mechanic Posted September 18, 2013 Report Share Posted September 18, 2013 Reynolds do recommend welding rods and also technique to be used to get the best results. If you drop them a line they will send you details of all the cycle tubes available (there is a lot) and also a price list. Minimum order £150 but you can get drawn tubes, so tapers ovals all sorts even chainstays pre bent. Quote Link to comment Share on other sites More sharing options...

Bionic Balls Posted September 18, 2013 Report Share Posted September 18, 2013 i would rely on what leeson,marino,jaf and so on have proven with their stuff. test frames,early products:mild steels,maybe crmo if youre confident with mitering and stuff and a miscut tube isnt an issue anymore(could happen,no?) production frames:4130 or 4140 crmo,with 4130 a bit lighter because of the higher tensile strength,where the 4140 is weldable with less "moving"in the material due to heat,and a bit cheaper. later on i´d make individual stuff,if anyone wants to break his neck using tange prestige tubing on a trials bike its customers choice(mean example lol) also if youre really serious with this youll recognize soon,theres a market for lighter stuff than 2500g for a frame,you should consider heat treating below frame weights of 2200g Why would you consider heat treating a lighter frame, unless you'd changed the material?

FamilyBiker Posted September 18, 2013 Report Share Posted September 18, 2013 it adds elastic module and final tensile strenght,no? for me that means same ultimate strength as a thicker walled tube without treatment. correct me if i´m wrong,i´m more into other bike related stuff than austenite and martensite and such...

FamilyBiker Posted September 18, 2013 Report Share Posted September 18, 2013 (edited) out of real interest(i know this forum,hence i mention that lol),when would you recommend a thermal treatment for a bicycle frame and when not? i was just pointing out what my limited knowledge about metals allowed me to see,thats what i love in this forum,there are so many different people and every one of them has a clue of his genre,this gives a massive amount of knowledge available for all. okay,i´m not quite sure if really every one has a clue of his stuff here,but hey,you know what i mean edit:you can also drop me a pm if you dont mind,i´m not afraid of higher technical terms being used...

Bionic Balls Posted September 18, 2013 Report Share Posted September 18, 2013 Family Biker- on steel frames I can't think of many occasions when it'd need heat treating, though I don't claim to know all of the different steel types used on bikes nowadays (some materials always need it!). Generally speaking it'll improve the toughness (which I'd expect to be good enough anyway) and reduce the risk of any unexpected distortion (linked to residual stresses)- a frame needs to be nice 'n straight after all. I'm sure there's other good reasons that crop up too. Aluminium is a completely different story.. f**me- the word "stainless" is just too vague! I'm still intrigued as to whether a 304/316 frame will be any good..will at least look good that's for sure. Adam Quote Link to comment Share on other sites More sharing options...

I'm sure there's other good reasons that crop up too. funny story:i was the first person for which marino has been doing a heat teatment to a frame.it came out like a banana,lots of emails and thoughts later there were kind of "frames for the frames" so they could stand the process. we are learning new things every day lol only downside was the new fame that had to be made,which is still the best one i had. that could be why i´m a bit heat treatment biased,i only can tell good things about it adding strength and so on about it i know theres hardly any aluminium alloy that doesnt has to be treated,i think 7005 can be cold-stored for a while and is releasing tension by itself then. i like stainless a lot,because of the look,but as far as i know the higher alloyed steels(should be the better term) arent as good in ultimate tensile strength as 4130 and similar steels. as always,corect me if i´m wrong,next time i´ll be knowing better if Edited September 18, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
