Title: Loco/Tender wheel profiles
Post by: pete3000 on January 16, 2014, 08:30:11 AM

Reading a very old copy of model engineer the other day, one of Martin Evans 5" plans. Despite looking through several copies I couldn't find anywhere about the profile the wheels should be finished with, in particular the edges which are in contact with the rail.

I've got the round without corners profile  :ROFL: the axle hole and the back of the wheel machined and the overall outside diameter dimension plus a bit for machining "the finished profile"
But can't find any reference to the contact patch.

 :help:
