Steve,
You can find it by doing a search on the web. It is a hand tool not unlike
a large dentists drill. It has hundreds of attachments of different sanding,
grinding, and drilling discs. We use it to cut off stainless screws in
seconds. The same disc we used for that works great for the mast holes. You
start by cutting a slot about 1 mm wide and then another next to it and
another
and so on--all inside of your pencil outline. Then you turn it on a bit of
an angle and begin removing the meat left between slots. Change to the
correct size grinding wheel and do the radius at the top and bottom.
Shouldn't
take more than a couple of minutes to do all three t-ball holes with very
clean
edges and no fractured carbon splinters inside the mast.
