Re: [ATM] ATM: Importance of waxing tile tool channels

Yes, Bob-

I AGREE WITH YOU!

The beauty of the waxing methodology is exactly conducive to what you want 
to do: control the depth of the channels, perfectly in step with the wear of 
the faces of the tiles, to keep their depth at about exactly as you 
describe.

THAT IS EXACTLY WHY I RECOMMEND THE WAX; IT LETS YOU HAVE ABOUT A ONE 32ndth 
INCH FOR CHANNEL DEPTH, ALL THROUGH OUT GRINDING!!!

We are in absolute agreement on this, Bob. YOU ARE RIGHT!!!!

Wax is the cleverest way to do this. No grit will be lost through the 
shallow channels that you carve to custom depth after coating the tool with 
wax and then excavating off the surplus, so that you have shallow channels 
to begin with. Then, as the tiles wear down, and you can see that the 
channels are closing (tiles wearing down to the level of the wax) you simply 
re-excavate to your prefered depth of channels; 1/32", or 1/10"

How do you maintain your shallow channels without using a reducable filler 
for constantly keeping their depth the same, all throughout grind?

Here, from my previous post, are the wonderful advantages of using wax fill 
for the channels. I simply challenge anyone to try it; I have a dollar for 
someone who tries it and does not like it so strongly that he does not use 
the method for the next mirror. There it is, in writing: $1 for anyone who 
does not have an absolutely perfect experience using the wax method. Here 
are the advantages again:

Now, Donald, here are the extra reasons, and they apply for the molded
cement tool; some of them also apply to a constructed, all ceramic tile
tool, that is used from starting out flat. (I reiterate the most important
reason, first).

1. If you leave the 3/32" by .20" deep channels unwaxed, and try working
with the mirror on top, the grit will immediately run out the sides, and be
wasted. The function of the channels is not impaired if you excavate the
channels down to just below the level of the tiles, with a little screw
driver. Each time the tiles wear down to the level of the wax (you will know
when this happens) re-excavate the wax again to just below the level of the
tiles. The grit will not run away.

2. For the pre-curved cement and tile tool, the wax also helps to hold the
tiles on strongly;

3. For the pre-curved cement and tile tool, the wax seals away the sand so
that none of it can get out and murder the mirror;

4. For either of the kinds of tile tools, the wax will safeguard against a
rogue grit rolling across the face of the mirror, and again murdering it.
The wax will usually trap it just before it gets across the channel.

How about them apples, Donald?

Glad to help you, partner-
