What's too loose? A "snug" balance rail bushing may not cause a sticking key but it sure can cause a lot of excess friction.

If you leave regular cauls in until they are completely dry they will be way too loose for my taste. I actually ordered a set of cauls from BiIl that are not oversized (the regular cauls are .148"). Even so, I remove the cauls after about 15 minutes so they can swell slightly. Otherwise they are too loose. A snug balance rail bushing rarely causes a sticky key, and it will correct a lot of key squaring issues making key leveling easier an quicker. -------------- next part -------------- An HTML attachment was scrubbed...
