At long last, I have finished building up my Raleigh Twenty. It took a lot longer than I expected for various reasons, choosing a part that didn't work, missing some small part here and there, and when you get down to it, I'm not much of a mechanic. But it's done, so here are some pics.

The build is:
Frame & fork-1973 Raleigh Twenty;
Headset-Tange G32STR Aheadset, used with 26tpi nuts from original headset and Sinz seatpost clamp;
Stem-Nitto Periscopa (Technomics not quite tall enough, don't ask me how I know that);
Handlebar-Soma Sparrow (installed upside down to get the grips higher);
Grips-Rivendell Portuguese cork, with three coats of Zinser Bullseye Amber (when you glue them to the handlebars, the glue may set better and faster if you shellack them AFTER you glue them, don't ask me how I know that);
Brake Levers-Tektro BMX levers;
Shifter-SA SLS 3C (grip shift won't work on Sparrows, don't ask me how I know that);
Bell-Crane Copper Suzu;
Front hub-SA HBT, 36x451;
Rear hub-SA SRF3, 36x451;
Rims-Velocity Synergy;
Tires-Primo Comet 37x451;
Brakes, Tektro R-365 (had to make a drop plate to use these with the Pletscher rack);
Pedals, KKT Top Run;
Crankset-Sugino RD2, 165mm;
Chainring-Sugino 46 tooth;
Chain-SRAM PC-7X 1/8 inch;
Cog-SA, 18 tooth;
BB-Shimano UN72, 116mm, with Phil Wood cups;
Saddle, Brooks B17;
Seatpost-Thomson Elite, 28.6x400 (330mm Kalloy Uno not tall enough, don't ask me how I know that);
Seatpost clamp-Crow Cycles;
Rack-Pletscher C?;
Kickstand-Pletscher Esge (if I were a good mechanic, I wouldn't have had to cut it five times to get the right length--at least I didn't cut it short).

I've added a couple photos of the drop plate I made so that brakes could fit with the Pletscher rack. Nothing big, just some flat bar with a couple holes drilled in it, but it works.

Also, I should point out that the wheels were built by 3Sports, my LBS in Richmond. The paint job on the frame and the pump is by Canyon Custom Air, also in Richmond. Both did a great job and I recommend them.
