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
http://www.shaptonstones.com/stones/diamondlapping/dmdmovie.html
The video shows Harrelson use the Shapton DRLP to keep the stones flat
and also to reference the blade bevel (That's how he words it. Really I
think he means he is giving the blade it's general shape and making it
very flat to speed sharpening.) The DRLP looks great but I do not think
I can afford it now. I am not keen on using sandpaper and glass to keep
the stones flat. It seems wasteful and takes up more space. I do not
want to use the Shapton compact lapping system because keeping the
powders in stock seems like a pain.
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
I use a diasharp to flatten my shaptons. My diasharp is about the same
size, but with a starrett straight edge a .001 feeler will not pass and
there is no light straight into the sun. So it's flat.
I put pencil lines on my shapton, wet the diasharp, scrub around in
circles, back and forth etc. Wet em again, watch for the lines to
mostly disappear. Then mark em again, and flatten till they all go
away. It's flat again till I really grind away an iron.

You're right, I think, if you use it about as much as Steve does. But
then if I remember right, Steve goes through whole sets of stones and
likes the Shaptons because they take the longest to wear out.
It takes me an awful long time to even get a Shapton to the point where
it needs flattening. Had this set over a year and had to flatten 'em
three times. The 8000 I haven't flattened at all. I haven't even gone
through half the powder. The lapping plate still shows flat on every
straightedge I check it with. Haven't run a dial indicator over it.
Suppose I ought to try that. :-)
But for me, while I guess that plate WILL go out of flat sometime, I
think I got a few years left before it happens. Then we'll see what
fancy toys are out there to replace it by then.
Don't believe the hype about "flatness". I've had 5 DMT 6" "stones".
They weren't all even close to specs on flatness. A couple were within
specs. I've had one blue stone wear out and it was replaced by DMT. It
took forever, but they did make it good.
I started to flatten an oilstone with my coarse DMT, but stopped when I
found it was ruining the DMT on the ends where the oilstone was making
first contact with the DMT. I know they recommend using them for that,
but I won't use mine to flatten other stones.

Stone vs. diamond, to me, is like the difference between heavy duty AA
batteries and alkalines. Alkalines last so much longer that heavy duty
batteries never even come to mind. (Especially if the heavy duties
were half again more costly.)
Spending both your precious time and money on supplies and sharpeners
for your sharpeners seems like a waste to me. My DMT diamond plate
will outlast me and it was a one-time $10 cost (from a fellow
Wrecker.) That and a few bucks a year on superfine grit paper keeps
everything I own sharp. I also bought a diamond cone hone which works
on the curved profiles of my carving gouges.
P.S: If I were to bend every crowbar within 1,000 yards of me on a
sharpening system, I'd go with diamond plates on a Veritas Mk-II
machine. (Chances against that happening: gazillions to one.)

Hi Peter,
I still have the original containers. I would say I'm half way through the
powder for the 2000 stone and have most of the container for the 8000.
I'm not anal about flattening the stones. I use the entire surfaces in the
sharpening process. They stay pretty flat. It doesn't take much powder. The
2000 stone I probably flatten every dozen or so sessions. The 8000 less
often.

They also have a cast flattening plate for less. It's what I've used for
over a year now. Works great.

It would have to.

yep just rock powder mine was a mix of 220 and finer I think. I don't remember
where I got it but I thin kit was the same as this
