<DIV><FONT size=3><STRONG> After using many forms of electric s=
anding devices I don't see how I can take a un -shaped set of new hamme=
rs & effeciently design a hammer shape with this tool. P=
erhaps that's not what it's use is for. I currently use a small sa=
nd cat belt sander & more recently a Makita hand held b=
elt sander with a 1 inch wide by 18" belt. It's a bit awkward & don=
t' recommend it for anything but gang filing when shaping new &nbs=
p;hammers held in a gang clampm in a vise with plenty o=
f clearance.</STRONG></FONT></DIV>
<DIV><STRONG><FONT size=3> I do however use the makita on hung =
hammers when trying to do huge amounts of shape redesign & felt rem=
oval but I just do the rough work with the tools & finish wit=
h 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.</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=3> my guess is that Joe's tool is extre=
mely effective for the applications it was designed for such as upright=
actions.... Right Joe? Or splain it further to dense heads like me. Ma=

<P>Carl,</P>
<P>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 d=
own and not the top. How is that accomplished?</P>
<P>David I.</P>
<P>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 ha=
mmers I usually squeeze the blades with thumb and index finger to sand =
only the sides. <STRONG>Remember</STRONG> <STRONG>that this tool =
is</STRONG> <STRONG>basically roughing it in. As Nick Gravagne sa=
id in a class "We're just shoveling dirt". Final shaping and squa=
ring is done using standard paddles or your favorite procedure.</STRONG=
