I found it interesting but completly useless actualy. How does one get the base "flat" by hand in order to get to the "polishing" stage? That is the problem I have with my blocks is getting a flat base. I have yet to be able to do it by hand lapping. I can make a nice polished look but it isn't flat. 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 his next articles will inform us on a decent way to hand lap a block....
