Linda,
Have you also checked the BR holes? Sometimes too tight holes (or not wide enough at the top of the hole) can masquerade as (or aggravate) a slightly tight bushing.
Otherwise, I would suggest treating the bushings with Teflon powder (or a drop of VS Profelt) and use an appropriate metal key bushing caul (heated) to size them.
If you happen to already own a Key Bushing Iron that may work better. Pianotek has it with both tapered tips and straight tips. I would probably choose a straight tip in a case like this.
IOW treat the cloth, not the wood in this case. At any rate I would try one or two in different ways to see what works best.

I used to have to ease keys on some Chinese pianos where the keys were made of plywood. I modified a pair of Vise-Grip pliers to do the job. I ground the tips of a regular pair so that they would enter the average slot size in the key. I don't know what kind of wood you have there, but likely it's some kind of hardwood. You could also use some heated cauls to iron the felt, rather than crush the wood.

Anybody else had this?
This time, it's on a Kohler and Campbell 600: key buttons too hard to squeeze, even with compound leverage pliers; already-thin key bushing cloth you can't iron any flatter - this isn't the first time or the first brand where I've encountered this annoying scenario.
What have others done about it?
Thanks,
Linda Scott
