Hi,
I'm want to buy Shapton professional stones and am thinking about how to keep them flat. I watched a video clip on their website
For keeping stones flat, how do the DMT duosharp plates compare to the DRLP? Which grade duosharp matches the DRLP? Which grade DMT stones do you like for flattening stones?
I have read old posts here that say using a DMT plate to keep waterstones flat is a bad idea because the way the diamonds are attached to the substrate is destroyed by the waterstone. However the Shapton stones are ceramic so maybe that will make a difference. How durable is the DRLP when used with stones?
How durable is the DRLP when used with steel? I have read old posts here (some by Steve Knight) that say diamonds and steel are a very bad match and the diamond stones will wear out quickly when used with steel. Does this apply to the DRLP?
How much flatter will the DRLP keep the stones and will it really affect sharpening time or quality? The DRLP is flat to 0.0004" on the stone side and the DMT diamond stones are flat within 0.003" or according to Lee Valley 0.005".
The shapton professional stones are 8-1/4" x 2-3/4". Duosharps plates are 10" x 4". The Shapton site does not say how large the surface is on the DRLP.
The DRLP costs $489 and a Duosharp plate costs $119.
Part of the problem is during my phone conversation with Harrelson he hyped the DRLP so much he made me think I cannot do without it. Maybe it is that much better but maybe he is stalling a sale by trying to sell me such an expensive system.
Any info or experiences appreciated.
Thanks!
Peter
