High guys, remember me, mister chipped tool? Anyway, I've been working on my 12.5" full thickness mirror, and it's time to put away the grits, and break out the pitch! WOO HOO!

I have a few questions;
1. What type of stroke should be used? What type of stroke do YOU use? Should i continue with "W" strokes, or is there another stroke to use for polishing?

2. When pouring the pitch, is it better to place a coat of wax paper on the surface of the mirror, instead of CE, then pouring the pitch onto it? I really do not want to glue the mirror and tool together.

3. When exactly should I start faceting the pitch?

4. I planned on using a window screen to "micro facet" the lap, is this acceptable?

5. What should I press the lap with? DO I need extra weight, on top of the x number of pounds that the full thickness mirror weighs now?

Thanks for your patience, and reading this far, I know that's alot pf questions to ask, but I've put a lot of time into the mirror, and it's my first one, and I really don't want top mess it up.

Thanks Again;
John
