Thread: Machined glass

Anyone know of a good place to get a proper piece of machined glass for honing?

Machined glass???

How would that be used for honing? Most glass seems to be pretty smooth. If you want something to stick your sandpaper onto, go to a glass shop and ask for a piece of plate glass cut to the size you want. That stuff has been gound flat and polished in the manufacturing process.

Most local hardware stores (excluding home depot) should have glass cutting as a service. This glass should be a sufficiently flat for lapping a stone.

I believe I had mentioned machined glass in another thread, but I should have been more clear. I was referring to what I used ... which is a piece of machined optical filter glass that someone gave to me (and instead of tossing it when I moved I decided to use it as my flattening surface).

what about for use with a razor. removing chips?

Glass should work fine. I know some other members have actually used their norton as a flat surface to lay or wrap the wet/dry on or around. I have not personally tried this technique.

I have tried using the norton with limited success. The paper won't lie perfectly flat. Its better to glue a sheet to a piece of glass. I use a 12 x 12 mirror with contact adhesive. Don't use water based glue(PVA) as it warps the surface of the paper.

What you are looking for is called "float glass". It is absolutely flat. Check the Yellow pages for glass suppliers and call them.
They are not cheap!

I thought nearly all modern glass was made using the float process?
