Hi Terry,
The ones above, sound like them.
As to how I use them, well it takes a couple of tries, till I get down to a
specific
motion, and it changes, from action to action. I suppose it is the density
of the felts,
or how loose they were initially.
As Roger stated, take all the parts out, and just get into an assembly type,
action
once you have figured out how many passes to make, for the particular part.
It is surprising, how fast and consistent, you can be once you have
everything
laid out. And yes sometimes it appears you are using the wrong size for a
particular pin size, but as long as you stick to the same number of passes,
it
will be consistent.
I used the broach set from Pianotek before that.
