It is very unlikely to have been done with an end-mill. I don't think that vertical milling was a common process in 1921. It might have been horizontally milled. It is possible to generate exactly the correct shape with a shaper and an inclined rotary table, and that might be what was used. As for the tuning for speed ideas, it would probably need more than the current 2.5:1 compression ratio too. But with no significant brakes and most of the suspension built in to the saddle, I don't think I want it to go any faster. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
