Addendum.

The next step was to decide what I wanted to make the frame out of. This was dictated mainly by what I could get, and what tools I had easy access to. I didn't want to make a fool of myself begging commercial frame builders or bicycle shops for catalogues of lugs or tube sets, so I searched the net until I found someone with a decent selection on-line. That place was Ceeway, a company in the UK that sells Columbus tubing and a great variety of lugs via mail order. They have a really neat website where all their products are pictured, making selection easy.

I chose Columbus Thron CroMo steel tubing for my frame, and chose to join the tubes using lugs. This was a good material to use for a first frame for the following reasons:

  • It's not very expensive. My tube set cost about 30 UK pounds.
  • It's double butted, so the resulting frame will be reasonably light.
  • The tube ends are reasonably thick (0.8mm) compared to the more expensive tube sets, so I figured it would be forgiving of a learner brazer.
  • The tubes are available in the diameters and shapes that I wanted.
I chose to use oversized tubes, with a 28.6mm seat tube and top tube, and a 31.7mm down tube and head tube. Ceeway had really beefy chain stays, that were 30mm x 16mm oval at one end, and tapered down to 12.5mm diameter. I figured these would work well on a track bike, as I wanted the bike to be as stiff as possible. I also used fairly fat seat stays, 16mm diameter at the top, and tapering to 12.5mm at the bottom.

Next step was to choose lugs. I looked at all the lugs available from Ceeway, and ruled out those that wouldn't physically fit my mix of tubes. That narrowed the choice to just a few sets, which was refreshing, as too many choices just makes it harder. I went for fairly minimalist lugs, the Saba '51' series. I went for a Long-Shen LB-106 bottom bracket, as it had no cable guides and was compatible with my mix of tubes. For the fork-ends, I chose the Long-Shen LR-15 cast track ends, as I liked the way they plugged into the seat stays and chain stays, rather than using slotted stays.

The tubes and lugs arrived about a fortnight later, at the cost of all of 70 UK pounds, including shipping half way around the world.
