I don't really see why splitting is a problem since the goal is to have support around the tuning pin generally and the split probably doesn't make that much difference. But I have heard of individuals soaking them in thinners such as are used to thin pin driving fluid and driving the bushing and then the tuning pin while the bushing is still slightly wet (using pin driving fluid as well which I prefer). The thinners for PDF are generally xylene or mineral spirits which will not mar the lacquer based finishes on the plate. My own experience is that if the bushing is tight enough that you have to drive it to get it into the plate then the tuning pin will simply compress it rather than cause it to split. It tends to be when the bushing is too loose that it splits though sometimes it seems to want to split anyway.

I wonder if a drop of CA glue after pin insertion would freeze the bushings to prevent splitting. I don't see how it could hurt. Dean Might work. I was thinking maybe soaking them in a hard drying varnish instead of water. Or even just leave them out. Ron N I used the varnish, oil based and it worked the one time I tried it, soaked them in it, let 'em dry then strung with them. The next time I tried it it didn't, go figure!
