ATM A novel way of beveling?

["Terrance (Terry) G Bondy" <bondys@netrover.com>]

Hi,

I'm currently hogging out an 8" blank with a plate glass tool. The stone I 
bought could not put a satisfactory bevel on the tool in any reasonable 
time, so I found I had to keep beveling every 10 or so wets. Necessity 
being the mother of invention I took a used concrete cutoff wheel down from 
a workshop shelf and placed it on top of some wet paper towelling on the 
stand. Using the spritzer I wet the thing down, and holding the tool in my 
right hand with the index finger along the edge (sort of like you would a 
yoyo) I pressed the left hand against the back of the tool to rub the 
working edge of the tool against the cutoff wheel, holding the tool at a 45 
deg. angle to the cut off wheel. The left hand did all the back and forth 
motion while the right arm stayed in place (its all in the wrist).  The 
plate glass would leave a chalk like mark. Rotating the tool a bit in the 
finger tips every couple of strokes and walking around the cutoff wheel, I 
got a bevel three times wider in about half of the time!

When doing some backyard landscaping, I bought this wheel when I rented a 
gas-powered cutoff saw to make short work of some concrete "ties" when 
doing some small retaining walls. That being long done, the blade as 
available for other purposes.

Part of the label on the wheel was previously destroyed, but the specs on 
the wheel are:

<worn off> reinforced cutting
<worn off> eel for use on gasoline
<worn off>wered hand-held abrasive
cut-off machines.

<worn off>ply with Safety Code HS(G) 17 (03)
Canada: Comply with CSA Standard B 173.5

for stone

wheel operating speed: 5460 rpm
wheel diameter 350 mm (14")
wheel thickness 4.0 mm (0.16")
<worn off>er hole size 20mm (0.0787")

I dried the wheel off after using. After using the wheel for its new found 
purpose, I would not recommend that you never use it for cutting stone 
again. On the back it states "When cutting with water attachment use wheel 
up the same day."

Has anyone considered using a wheel like this fixed to a plywood tool to do 
rough grinding using the chordal stroke, when starting with a flat blank, 
but before setting up a tile tool?
