help needed, stained white oak with amonium fumes

[Cannoneer]

This carriage was fumed with ammonia, then polyurathane finish applied, then sanded on glass till the grain was filled.

MikeR C,

What do you mean by "sanded on glass?"

[MikeR C]

I use 3M photomount spray adhesive and stick down wet or dry sandpaper to a piece of glass. I my case it is a window out of an oven, very thick and probably tempered. The object of this is a flat surface to sand things FLAT. For the poyurathane I wet the sandpaper with lamp oil, 100% parrafin. For metal I use water.

Thx

My compliments! The process is an interesting extreme. It illustrates dedication.

I use the same technique for polish flat sides on guns before blueing. I have a small foot square, 1/4 inch thick piece of plate glass that came out of an a department store window for small parts  and a long piece of marble for big pieces.

Yes; I know for metal it is SOP but for wood, it boggles the mind. I have done it with metal but not with so much prep' for wood.

Thanks Mike; I've never heard, or thought of this before, but it sounds like a good idea, I'm going to give it a try.

Keep in mind that you need enough finish on the wood before you use a liquid. Once I have a couple coats of poly, then I sand it wet with oil. It makes the finish dead flat (meaning no ripples, orange peel or whatnot), but not glossy. Once it has sit for a couple of days I polish with 0000 steel wool to give it a semi-gloss. I'm still not convinced it is appropriate for a carriage finish, but it is sure pretty

Yes it is! Mike, I was talking  more about using your method (a piece of glass with the sand paper affixed to it) to attain the final surface finish on the wood, (I think it would keep it flat, with all the edges sharp) before putting on a liquid stain, and then a hard finish of some kind. I can see what Richard means, I don't think this would be manageable for a larger piece, or project, but for the miniature carriages that I'm working on now, I think this will work fine.

"I don't think this would be manageable for a larger piece, or project..."

 You can do something similar with larger items; just use the glass/sandpaper as you would a large sanding block. Won't give as perfectly flat a surface, but still works pretty good. I've done this (using a piece of aluminum tooling plate instead of glass) for refinishing old butcher-block top work benches.
