    The oxy-map kits will work for a few braze-ons but you'll exhaust the oxygen quickly, meaning you'll have to buy more.

    If you really want to build frames, it'll cost... Unfortunately...

    I guess you are referring to the 0.6-0.4-0.5 seat tubes (the other round tubes have 0.7 butts as shown in post 8). I did use one on a recent lugged built. It think it's intended for TIG since the...

    Cutting the lug shape is already a lot of work, I would purchase the blanks. If you make your own you have to a) thin the 0.058 tubing on the lathe; b) mitre it; c) weld/braze; d) clean the...

    I don't think it's a good idea. Making a frame is a bit more involved than welding tubes together. And some welds are quite tricky (e.g. seatstay to seat tube). As you mention a welder will have no...

    Thanks for showing the pics. The ovalisation looks great. I'm curious to hear what happened with the butted tubing. Cool project.

    Yes as Andy says a 395 mm is about 30 mm too tall for the intended wheel. Your fork is intended for a 700c wheel and big tires. I would not use it for this build.

    The problem with short headtubes...

    I think brazed racks are cool. In some instances you can be smart about it and make them part of the structure. Like on the old Singer frame that used thinner fork blades because the brazed rack...

    It's hard to say really, I think everyone is speculating to some extend. I'm sure it would be ridable, but it might not be best for spirited riding and/or climbing hills, which also increases wheel...

    So it's a roadster with a long TT it seems. Nothing wrong with roadsters, they are still being ridden and produced in millions. The main problem is that there will be a lot of wheel flop, and this...

    Little update. Using wood wasn't going to work easily so I used carbon fibre. I kinda messed up trimming the sides but it's not bad.

    Generally, you would want a disk-specific fork (heavier blades and special dropouts) if you wanty to use disk brakes. So you would need to decide beforehand. Otherwise it's not a bad idea to get some...

    EL OS was one of the thinnest gauges tubes as far as I known. Frame weight should be around 1700 g. The fork around 700 g. Lightest carbon frames are 800 g, lightest forks 300 g but these tend to be...

    Fork crown is Haden and I think the lugs are Prugnat. I'd say it's from the late 70s. I haven't seen much of that crown on production frames so this could be a custom?

    I think that superposing a series of narrow strips oriented along the two curves would work. But that seems like a lot of work, I can't figure out a way to do that efficiently....

    Yeah I'm thinking fibreglass or carbon fibre will conform to the shape naturally. Simply rolling the fibres + epoxy should leave a decent finish?

    Here is a pic. It's cracked and far from flat, but it's not that bad given my meager means (water and rubber bands). There are a few things I can try next.
