Yes, you can refurbish each surface to where it is nice and shiny again but you have to remember that the thickness of the glass is also an important part of...
The 1x1 tiles are about the smallest that are available. You can make glass tiles smaller if you desire. If you do glass for the tiling, make sure that the...
For polishing a surface, there is no need to embed tiles into the lap base. The tiles are there only to provide a hard surface to grind against. The soft...
... When you mentioned this, I wondered if it would be possible to manufacture the mate for those surfaces that really need it. Mold the tile tool against the...
Bob, Good advice. Yes I have done as you have suggested. My greatest hope is to simply remove the old coating that has bubbles, and discoloration. The two...
My optician told me that if I use broken pieces of tile, and embed them, that the irregular patter, will tield a more accurate grind. I was thinking of using...
Bob, I was under the impression that after the tile is imbeded into the stone that you then remove the stone between the tiles, to create a space for grinding...

I second Ken's opinion. It is not 1 in 100 or even 1 in 1000 chance. It is zero chance that you will succeed in improving that lens no matter what the...
Enough already!!!!!!!! What you want to do can't be done without destroying the properties of the lens. Almost exactly is not close enough unless the almost...
I do not understand you use a "guage" to check the "accuracy" of a polish. The normal measuring instrument for this is the Foucault tester to measure the...
Jerry, Thanks for your opinion, and I regard it highly. But, to do nothing is a waste of potential experience, to do nothing is to evade an opportunity to...
Jarvin, I'm disapointed that you charge ahead without fully knowing that I have said that the lenses are already ashtrays, there is no freeking harm in trying...
Richard, I don't believe what I am doing is heretical, but I think I am simply making *templets*. I use the term guage, cause I use it to periodically chech...
