Hey Fred, At the same time steam the BR hole add the right pin and the hole is also sized. If they're buggered up glue size them. Que no? I always do this and rarely have to touch the BR hole with a tool because it dries perfect (well, most the time <G>). It usually solves the pulley key syndrome too. Jmtb.

I wrote about it a few years back, and there was a bit of discussion - check the archives. Me, I like to put keys in a pair of Spurlock's clamps, steam a set at a time (meaning half the BR, half the FR) using a travel steam iron (which emits steam through a hole) until the bushings swell "about right" (not enough to come loose). Then I follow with Pianoteck's precision brass cauls in a heat-controlled soldering iron (the parallel sided ones, not the tapered). Two quick passes with the caul rather than one long one: I don't want to encourage the glue to be liquid and move into the felt. Each pass with the caul is a bit less than one second per bushing - go through each key, then back through. Others like to insert the nylon cauls in the whole set and then apply steam and wait overnight to dry and set.
