My mill isn't up to fly cutting anymore so I have to start with stock copper from the supplier, which as you probably know, sucks but most DIY'ers are in the same position. I got a decent sanding block and start with 100 grit and then work up to 600grit and that is usually where I start to "polish" it. Even though I get a good print of silver compound it isn't anywhere near flat. I can get it to where the little AMD symbole on top of the die makes an impression in the silver compound though. Best I can do with what I got and it has taken a lot of work to get that good. Not to many of us can or wants to afford a Lap Master. 
Maybe is next articles with inform us on a decent way to hand lap a block....

Good statement. I do rely on our Lapmaster machines to get things flat and these are not your everyday item. I can and have done this by hand many times, and experience counts, which is hard to get unless you do this a lot. Writing a technique guide won't solve the experience factor problem that usually is the main obstacle to flatness.
