Thread: Lapping / Slurry stone question not covered in the Wiki

Frankly, the DMT XXC is £119. That's pricey. And it seems, I'll have a deep scratch pattern on a a stone that should have no scratch pattern. I'm assuming that once I flatten the hones with the XXC, I'll need to lap it again with a finer stone, a 325 perhaps, and then again with a 600 and so on and so on.

DMT makes a 325/600 Continuous plate
Buy DMT DMT Dia-Sharp Double-Sided Continuous Diamond Whetstone from Axminster, fast delivery for the UK that's "only" £69. Couldn't I use this?

I know that this thread is long, and for that I'm truly sorry. But I'm innocently ignorant about lapping.

You really shouldn't use any DMT's above 325 for lapping. The diamonds can be ripped out of the nickle substrate that bonds them to the steel plate, which renders the DMT useless. If you want to go above 325, you should use something other than a DMT.

There is more money to invest, but it's necessary if you want the hones lapped so you can used them and don't want to spend hours and hours doing it. It's also a one time investment that should last decades (if used properly). Or if you don't foresee the need to do lots of lapping in the future, you can sell the plates and get back most of our money.
