Rob - I thought I had .5 PSA but it's not, it's .3 and I got it here. For .5 on the Apex get some glass blanks from Ben Dale, attach a 6000 grit tape and apply liquid CrO. Or, go to the pharmacy and pick up some 3M NexCare Gentle Paper Tape in the 1" width size. I've started to play around with other versions of 1" tape as well.

Edit - Diamond pastes in a variety of grits down to .1 micron can be had here. .1 Micron = 0.000003937007874015748 inch, difficult to comprehend but anything you polish will show all your pimples in the reflection. LOL

Thanks for the link, Buzz. I wish I'd seen it yesterday- I just ordered a couple sheets of non-PSA. How do you like the stuff? I don't have a glass blank yet, I really should order one soon.

How does the DIY cut-it-from-a-sheet PSA stack up vs the polishing tape Ben sells?

I'm undecided. Nothing stands out and says "I'm the best". I've gone all the way to .1 micron diamond paste on paper on glass and don't feel that it push cuts any better than .5 CrO on leather. I think it's a skills problem. I don't go all the way like that very often so I'm short of practise. I'll keep at it though. the edges get so shiny they darn near glow in the dark.
