    Koya Bar, for a little something different.

    Just come across this.

    I've not worked out how to use it yet but seems pretty perfect -generates full size drawings, tube mitres (inc. BB intersection and I think fastback SS) all in an excel that'll run on anything.

    Don’t tell everyone! I’m still mulling it over.

    I could model it in Rhino to begin with, as I use it for work sometimes. I like the safety net of software designed for frame building though - I feel like I might draw something in Rhino and not realise it's totally wack before I cut tubes.

    Good call though, I'll probably model the wishbone seat stay in Rhino and unwrap the surfaces. Trying to eliminate as many compound mitres as possible in the design.

    Should I make a Current Project thread?

    It was on my 53cm steel track bike - pretty short head tube but measure it up and see how you get on.

    Thanks. It’d be slightly misplaced patriotism / nostalgia to doggedly stick with Reynolds as I’m a Scot. The all in-one think from Ceeway is appealing.

    Free BikeCAD won’t do mitres right? I’ve been trying to get RattleCAD to work on my MacBook but it seems you need a degree in computing from the 90s. Maybe I just have to find someone with a pc laptop.

    I’m eventually going to build a winter / everyday bike. What tubeset should I use?

    I weigh 60kg, it’ll be a 54cmish size, TIG welded with a Columbus Hiver or Condor Pioggia fork (360g with large clearances and mudguard eyelets!).

    Do I go through the complex ordering process with Reynolds to get 631, possibly not meeting their minimum order and asking a favour from one of you

    or

    Order Columbus something (thoughts?) from ceeway along with all the little bits

    or

    Get True Temper from Henry James (probably pricey inc. shipping but quite cool).

    I’m ok at TIG but would no doubt blow holes in a fancy tubeset. I have about 2m of 28.6mm x 0.9mm 4130 tube from Aerocom to practice on, but I’d prefer to use something butted and lighter for the actual frame. As it’ll have a 1 1/8” HT I think I’d like to use oversize tubes, though I’m guessing non-round tubes will be more than my paper-template-hand-mitring can handle.

    Thanks, as I suspected.
