Thanks all! (Mr.) Bill mentioned sizing leather with a drum sander a number of years back. Ironically, this was right about the time I stopped "liking" leather, so we never did tool up. The results with our current stock (Renner) have been quite precise, so any touch-up with pliers has been done with much sober fore-thought, and thankfully, quite minimal. However the guys had pointed out waste from thickness changes near the ends of the strip, and from what you all tell me, I think the drum sander will correct all that. (Hey Ed, what grit is on your drum... and can we do hi-speed manicures?) BTW, Bill's system is absolutely beautiful! I think we started with the cauls in 95 (?) then added the heated-broach system (thank-you Master Wolfenden!) from Pianotek, and finally the mortise-sizing cauls, whenever they became available. With the control over key-pin, mortice and cloth sizing, so little variable remains. We record the cloth and heating broach size (as many of you do) right on the key-board and in our records. How much easier this job has become! I'm very grateful for all the contributors to this process over the years. My assistants (I have four this summer) re-bush the keys, and it's amazing to me, given the right person, the level of precision they acheive on the very first set. Which pretty much explains "why" we really haven't "needed' any good key-bushing pliers. Here's one exception: When you've done all of the above to perfection, and have one or two keys that just won't give the right fit with the heated broach, and you've biased and wiggled the broach from side to side, and you're double-darn sure the cloth isn't over-length, and there's not the eansiest bit of glue squeeze-out hiding in there.... then I feel it's permissable to "resize" :>) the mortice a wee wee bit with the good ol pliers. The idea being that the next time these bushings are serviced, these keys will respond identically to their neighbors, with just one pass of the broach. BTW, one thing I'm really excited about, but haven't tried yet, is Jim B's suggestion that the broaches work with leather. I had ruled this possiblity out with even giving it a second thought. Will try it on the very next set. Again, thanks all!

Hi Mark, Getting back to the original question, I like the Pianotek JKE-2 and similar best (I've bought maybe 8 different designs over the years, including parallel, etc). I don't find them tiring. A lot has to do with exactly how wide the handles are while squeezing, and these fit my hand/feel best. The KPL-4f style are great to have for the purpose (not enough time to pull the stack, and you need to ease a few), but I don't like them for general use. Partly because the squeezing part is 1/2 - 2/3 the length of the mortise, so you really need to do 2 squeezes to each. Sometimes this is an advantage, when the wood is hard to squeeze - you can be more precise. But not for everyday, I don't think. Bottom line, though, is precision sizing (selecting) of bushings trumps easing any day, if you are the one doing the bushing (not that we don't need to do a bit of touch up from time to time). Especially true when bushing those hard wood buttons on Kawai and others, which don't want to budge with pliers.
