Thread: Lapping honing stones , diamond plates ?

Hey guys just a quick question if anyone has used the following plates to lap with or if anyone in general has had experience using these particular plates to lap hone with ?

I can get them locally cheaper than the eBay auction I just wondered if anyone had used them.

Or if you happen to have suggestions on where I can get some useful diamond plates in the uk that would be even better.

Most of there usage would be to lap stones I don't fancy trying my honing hand with a diamond plate just yet.

They would probably work but seem a bit small. How about just using sandpaper with a marble back.

I've seen diamond plates that were not actually flat, and ones that would shed their grit... DMT plates are reliably flat and durable. Most of us use their 325 for lapping. Finer DMTs don't stand up well to it, and in fact the mfr doesn't recommend the 325s for it either. They make an extra-coarse plate for lapping.

Myself, I've damaged my 650 by lapping but my 325 is still going strong.

Also, as the poster above said, you can use wet/dry sandpaper on a flat piece of granite.

Best wishes

Buy the dmt 8c (325) and don't worry any more...I have been using mine for years and works perfect.
I have found the sandpaper to be unreliable. When I go to the dmt I find the sandpaper got close but we aren't playing horseshoes here are we?

I did a little bit of a practice lap a while back on an oil stone I found that was heavily worn using some 320 grit wet and dry on a glass plate , the glass plate is used to protect work surfaces from hot pans etc. that seemed to come out really well however I did find I was going through a lot of sandpaper in the process that's where I figured I would look for a diamond plate todo the work.

When you lap with sandpaper etc I am assuming you go through the grit progressions as you would polishing using sandpaper ? As for piece of mind I would like to lap the C12k I have as while it appears smooth and flat running your hand over it seems to hint at a tiny raised area on the stone.

Run for your life, for an entire month my edges suffered until I threw that thing in the gargabe. YMMV of course
Im pretty sure the diamond particles become embedded in your hones, turned my 8k into a 325 ish k. edit- im refering to those plastic hones....

That's pretty much what I was hoping to get as a response to those diamond plates I figured they would either be a good basic diamond plate or trash lol thanks for the reply. I think I'm gonna practice my Lapps some move on the old oil stone until I'm confident enough to do my c12k.
