Clark, I have been using the Pianotek Perma-Grit sanding paddle with very good results for over a year now. The paddle, however, is a bit wide, with sharp edges, and it tends to get uncomfortable after a long shaping session. (The file is sheet metal impregnated with a permanent grit material - half of it coarse, the other half fine.) A good modification may be to trim the width and add a smooth wood backing about 1/8" to 1/4" thick glued to the back side of the file. The narrower width would offer greater control and comfort. Various grits of sand paper strips and paddles are used for the finishing touches. I would be reluctant to try the moto-tool approach preferring the control one can maintain with the elbow grease method, but if moto-tooling hammers works for others, who's to argue. John Piesik San Diego Chapter PTG JPIESIK@ARINC.COM I saw that alot of you folks use a moto tool to file hammers, I (even with a hammer file attachment) can not get the results I want. However has anyone else used the new Perma-Grit sanding paddle from Pianotek. It is great, without alot of effort you have complete control. I have done several sets of hammers with my 1st one and it does not show much wear at all. It is not very expensive either, only about $7.00 each. Take care, Clark Hale
