Reading the John Bridge tile forum, there
is a clear sense that the job of profiling and polishing
the edges of granite tiles (3/8") should only be done
by a pro granite shop. The people at Granite City Tools,
St. Cloud, Minnesota helped me out when I asked if the
granite edges could be milled and polished using a tile
saw noting a tile saw spun at the right speed, and already
had the water cooling/lube in place.
I tried to visualize doing this on a larger saw, MK 100
or 101, and I decided that the smaller Felker was much
easier to use.
You do have to buy ($130) a 3/8 or 1/2" radius profile
blade, so you can shape the edge of the granite tile. I
think Felker sells one too, about $130 bucks. I found that
the table does not track precisely enough to use this and
I found it easier to work by hand. Use several light passes.
One trip to Home Depot, about two bucks, and you have
what you need to adapt an Alpha arbor and Alpha diamond
grinding/polishing pads intended for a right angle wet
grinder for use on the TM-75 saw. It works great.
To polish, use the Alpha arbor and Alpha pads. Use a
12 mm by 3 inch cap screw, to mix measurements, inserted
through center of the arbor to attach the arbor to the
hub of the motor. A half inch spacer and longer cap screw
allow the blade guard to move outward to cover the Alpha
arbor and pads.
Relocating the plastic tubing to spray on the smaller
diameter Alpha wheel was done by drilling a 1/4 inch hole
in the blade guard closer to the spinning Alpha pad and
inserting the plastic water tube.
You simply work the granite edge pieces over the pads,
changing the pads easily on the velcro faced arbor. Starting
with a 30 grit, then moving through all the pads up to
1500 grit, you can get a very acceptable polished edge.
I did all my edges, about thirty linear feet, in one afternoon.
Costs, about $300 plus the saw but around here to polish
granite edges is about $2 inch, if you can find somebody
to do it. The break even point was about half my kitchen
counter, the first 150 inches,or about 12 linear feet.
This little saw did everything: cut, profile and polish.
I have since wondered why it's other possibilities are
not mentioned in any information that I have seen.
