The = beauty of the shoeshine methods is that it will work on either without = having to change methods or tools used to get the same results. When I = say shoe shine I am referring to the motion of the rag used to shine = shoes. While the rag bends to conform to the different shapes of the shoe, it = is not able to reach down into divots in the area being worked on, The emery cloth takes advantage of this fact as it shreds the felt off = the high parts of the hammer, first the sides and then the strike point.

After using many forms of electric sanding devices I don't see how I = can take a un -shaped set of new hammers & effeciently design a hammer = shape with this tool. Perhaps that's not what it's use is for. I = currently use a small sand cat belt sander & more recently a Makita = hand held belt sander with a 1 inch wide by 18" belt. It's a bit awkward = & dont' recommend it for anything but gang filing when shaping new = hammers held in a gang clampm in a vise with plenty of clearance. I do however use the makita on hung hammers when trying to do huge = amounts of shape redesign & felt removal but I just do the rough work = with the tools & finish with 80 thru 400 grit paper. Short of that the = foredom works bset for this particular job as one can focus all the = attention to shape on one side then the other & lastly the top. my guess is that Joe's tool is extremely effective for the = applications it was designed for such as upright actions.... Right Joe? = Or splain it further to dense heads like me. Maybe I need one Just my 2 cents. Dale Carl, so it goes back and forth...how do you get a particular shape? I'm = think of a worn hammer where I want to bring the shoulders down and not = the top. How is that accomplished? David I. David, just push the sander fore and aft to sand only on side of the = hammer. Press down to sand the top. Rotate the sander and push side to = side to clear waste felt. You need to do this since if you don't the = felt will clog the paper and stop working. Fifty or sixty grit is good = for speedily removing felt. For smaller hammers I usually squeeze the = blades with thumb and index finger to sand only the sides. Remember = that this tool is basically roughing it in. As Nick Gravagne said in a = class "We're just shoveling dirt". Final shaping and squaring is done = using standard paddles or your favorite procedure.
