Hi Scott do you know what the history is of the Wilson dropouts? That is when they were used for which bikes and for how long? Any insight would be very interesting.
AFAIK Stainless, silver soldered G.P. Wilson drop outs were only used on the Team Comp.
G.P. Wilson apparently just announced that it was closing.
Here's that business card:
This guy was desperately looking for a set of G.P. Wilson's a few years ago. Maybe do him a solid?
Team Comp - yes
Only model - no
All of the GPWs that I worked on were TIG welded to the 4130 tubes using ER309L stainless steel filler rod which is the most common filler rod for joining stainless to carbon and low-alloy steels. They welded really nicely and never undercut as opposed to drops from other manufacturers that were designed for brazing and were not really meant to be melted in a weld.
I enjoy reading about the nuances of the finest tig welding :beer::beer: I have ridden other bikes made to the same geo and using the same tubes as a TC but they do not ride like it. The dropouts, bullet machined stays, tiny tig welds and all the unique features of a FAT make them FEEL so different in a very enjoyable way.
Interesting. I always thought tube diameter and geometry defined a bike´s riding qualities. Good to know there are more subtle varieties going on.
They do too and as we all know FCC was ahead of the game back then experimenting with tubing gauges on computers etc and asking for custom spec TT tubes. Having had some input into bike design myself back then, I was always amazed by the mysterious synergy with FCC made frames, that made them ride so much better than anything else at the time or indeed since for a 26” HT bike.
@IROBOT You can never go into enough detail for us. I too am fascinated by the level of detail, understanding and sheer perfection you brought to FCC bike building, as well as the others there. I can still remember the first time i tried to find the welds joining the tubes on my 89 TC. Nobody could believe how tiny and smooth they were - no filing down either. It literally freaked people out !!
I could go on and on but you guys are probably asleep by now, so...
