    Hey so to give you guys an idea on how costly this is I was quoted $475.00 for a carbide plate, precision ground in the following dimensions:

    1/8 thick,
    2” wide,
    8” long

    And I asked that the plate come with a 1/8 radii on the two 8” sides.

    Mind blown! I can go through a fair deal of hardened steel platens for that!

    Holy-moly. I am guessing about $400 of that is shop time.

    I make my "disposable" platens from 1/4" x 2" steel. I am on my third one since 2017 so approximately one per year. Once they get dished enough to fail the flatness test, (the highly technical straightedge held up to the light), I make a new one. The latest is from 304 stainless cut from a length I got from Metal Supermarket's offcut bin for $5. It seems to be holding up pretty well. Now that I have the surface grinding attachment, I can true a regular steel one whenever I like.

    I have often wondered if one could take a common 12x12 ceramic tile, score it and snap it into dimensions for a liner.

    I added a subway ceramic tile to my old platen, be surprised how fast they chip *face palm*

    I’m going to get some 01 and attempt to put a radii on the edges and then harden it.

    You can buy a lot of O1 for $475 eh? Flattening that puppy out is an ideal application for my surface grinder attachment. Also, Nexus has liners for under $20.

    Dan I’ve found using my granite surface plate and steel ruler against the light that precision ground 01 is quite flat. I mean I could run it on the discs grinder to be sure.

    I have run hardened steel, ceramic glass and Graphite friction fighter.

    Large industrial grinders use the friction fighter and I will be as well this material has little to no drag, much less heat buildup in the belt, wheels or platen. Plan on building an aluminum platen at some point to see how it holds up

    John, do you recommend putting the graphite on top of the glass?

    Metal would be better as you can sand it then apply spray adhesive or contact cement

    Oh ok. I was looking to buy a glass platen from you soon, but maybe ill just try out the graphite instead on my steel platen.
