silicone carbide sanding sheets Harbor Freight
I just purchased a used Norton 4k/8k, and am waiting delivery. I need to lap the stones. Been doing a lot of research, and there are many, many opinions on what is best, or commonly used. Some people like the norton lapping stones, others say they also need to be flattened themselves. DMT is recommended by some, and others say they don't last. Etc, Etc... So I'd like to try sandpaper as it is economical, and a granite/marble slab is cheap too. Plus many here report good results.
Harbor Freight has silicone carbide sanding sheets of various grits. I've read several threads that some people use sic powder on a marble/granite slab with good results. So why not sic sanding sheets...?
HF has 220 grit, 500 grit, 1000 grit, and 1200 grit wet/dry silicone carbide sanding sheets. I was thinking of getting a pack of 220 grit and 500 grit to lap my norton stones. What are your thoughts on this progression...? 220 grit to flatten, then 500 grit to smooth the stones? Done under running water of course. Thx.
