Don, And people call ME crazy! lol. When I was in MD (Kitts) field work on one of the ASC units. I fit my electric dremel with the router fiting. First a round (ball type) grinder then a cylindrical (like Alan pictured) YES lots-and lots and lots of filings. I used 2 large magnets, one attached to the plate above the grinding and the other on the keybed below the grinding area in additinon to a vacumn. Don't have to repeat take your time but, hey, I just did. Slow & steady wins the battle. Good luck!

An angle die grinder with various carbide burrs will work fine to hog off the majority of the material. I use burrs with several shapes – christmas tree, cylindrical and one I find particularly useful is one like this: Then, still using the die grinder switch to a 2” sanding disc. Start with 36 grit, then move up in grits. That’ll get you a decently flat surface. I don’t think I’d use a Dremel for this work mostly because I just prefer using air tools. Wear a mask. The cast iron bits will go everywhere so cover everything up well, and because you are in a home (yikes!) you might use a vacuum as you work.

I need to grind the treble counter-bearings off of the plate of a piano in a customer’s home. I am hoping someone here has a good suggestion for which tool works best to give a clean removal that stays relatively flat. I would like to avoid screwing up the plate finish nearby, and leave a flat surface that I can put a half-round on. With the tuning pins staying in place, I’m thinking a flat grinding wheel might not fit in there. I can use a Dremel, but am worried it will be very hard to get it smooth and level. Keeping in mind the need to do it in the home, any suggestions? Dremel with a specific tip, maybe? Don Mannino RPT -------------- next part -------------- An HTML attachment was scrubbed...
