Hi Fred,
Being one of those guys that has played with steam in
various forms, once you understand the limitations it's a valuable
tool. Key bushing cauls and steam works well to get a fast improvement for
minimum dollars. It also firms up the B/R hole at the same time.
Another little dirty trick, that is fast for a big improvement, is too flex
the B/R pin forward, with an awl. Support the rear of the key with one
hand, insert the awl behind the pin and pull forward 2 to4mm this will take
the pin out of the cup, and firm the action up considerably. Cheat on the
front rail pins with a small twist. Then sell the bushing job. We do a
lot of re bushing because the customer notices a dramatic improvement. and
we point out that this is only a temporary fix.
Stalls re bushing for a year or so. Handy with limited budgets.
Regards Roger
