[pianotech] dremel tool

[Porritt, David]

David:

Mike is certainly faster than I am if he can do it in 15 minutes, but you can do a pretty respectable job quickly with one.  The Dremel is particularly handy when you have to do a GROSS change in shape - you know, the flat top hammer.  That requires a lot of felt to be removed and the Dremel does it in a hurry.

On a moderate hammer reshaping job I prefer using the 6-hammer wide sanding strip.  I start with 50-grit paper (cut apart belt sander material) and do the gross removal then finish with single hammer width finer emery cloth.  I can generally do a full set of moderately worn hammers in an hour.

Mike,

Sometime when you get a chance, I'd like to see a few photos of the finished product of a 15 minute hammer filing...

Thanks...

    I'm a frequent user and believer in the gospel according to Dremel.  For myself, I purchased two:  The first is a 110 Volt variable speed machine with a flex cable.  Used with a sanding drum and guide from Schaff, you can reshape a set of hammers in about 15 minutes, then final finish by hand if desired.  The second is a battery operated motor which is great if you're working outside with no power available or just want to use it for small jobs.  Its really handy for things like sharpening a chain saw in the field.  As far as accessories, I've found the usual set of grinding stones are needed, but also cutoff wheels and buffing wheels come in handy.  Dremel tools have their limitations, but in a pinch they can be an answer to a maiden's prayer....they make great Christmas gifts.
