    Question DMT325 as a lapper

    Gentlemen,
    I purchased a DMT325 for the main reason. lapping my waterstones. I have read a bit about this, and many talk of 'breaking in' such a hone. I gave my half a dozed stones a lapping, finding inconsistent results at brand new. Clearly this hone for our purpose it needs breaking in. If anyone has a thought on this I'd appreciate it. There is so much good feeling for this plate among users, I'd imagine it is just 'breaking' in'. Advice?

    Cheers Bobski

    General opinion on breaking it in is to take the shaft of a big screw diver and run it up and down the 325 to even out the surface. I did it with a broken off piece of a razor and ran it up and down about a dozen time to level it off and have had no trouble with it since.

    Hi Bobski, after lapping half a dozen stones you can consider your DMT well and truly broken in. "Breaking in" refers to moderating the cutting power of the DMT; your plate is now broken in and you can use it for lapping hones and, with care, fixing bad bevels and shallow chips on razors.

    For dedicated lapping atomas are faster, last longer and dont stick to hard stones. They are not bullet proof though and will not last forever. Any of them. Hard stones I start out with Wet/dry then use the plates to clean the stones up.

    I use a DMT 325 to lap my Shapton Pro ceramic stones. It works very well.

    The screwdriver tip from Razorfeld is the way to go. What you're trying to do is take off any ydiamond particles that may be a little larger, and thus scratch the hone in a way that you may not even be able to see. I'd still do it if I were you.

    You will notice large deeper scratches in your lapped hones if you have any stray high diamonds on your DMT. More so on your finishers (higher grit)

    Screwdriver or Hone a dull kitchen knife either will knock off the high points, but simply lapping stones will not always work to do that...

    I have to agree with Bill to however, a DMT325 is a good lapping tool but is not a HEAVY lapping tool, that is best left to the DMT120 or using Sandpaper.. I have not used the Atoma enough to judge it
