    Any tips on how to flatten /polish the backside of a chisel/plane?

    I’m getting a shiny polished chisel/plane bevel, or the curve of back iron of plane also nicely shining.

    But no matter how long i work on the backface of the chisel/plane, it seems i’m only getting more and more striations on it.
    Go from diamond stone to diamond stone with some glass cleaner on it, and end on the strop but i keep seing lines on the back face…

    watched this movie and doesn’t seem so difficult to me…

    i’m using eze-lap plates, but should be the same?

    Are your plates relatively new?

    I had a similar experience with my plates.

    I had used the super fine a lot less than the rest, so had not conditioned it properly.

    Whenever I used it it added marks rather than removing them.

    After a while though it bedded in and now works fine.

    They are quit new.

    But should I skip the coarse and only use fine / super fine for the back face?

    it depends which one(s) still need bedding in. I’d try a mixture and see if you can track it down.

    Then either avoid it or use it a lot to bed it in.

    ok i will try it!

    but probably has nothing to do with:
    – the type of glasscleaner i use
    – my technique (seems you can’t do much wrong as you keep the chisel flat)
    – use a strop or a block of wood; what is the difference for polishing?

    thanks for your suggestions!

    And what kind of pencil does Paul use to mark which points are hitting on the plates and which parts aren’t?

    Tried a white board marker but doesn’t work …:-)

    A black Sharpie.

    Paul uses leather for the face of chisels and irons, and wood for the backs.

    I assume that is because he wants to avoid rolling over the edge when stropping the back?

    I saw the same on the dmt movie; don’t use a strop but just a piece of wood. But my honing compound doesn’t seem to apply so nice to just some block of wood. But will try again!

    And the sharpie is just a brand of permanent markers, didn’t know that:-) assumed would be something special for woodworking 🙂
