Yeah, It won't be absolutely flat, I realise that. I've bought and worked with a lot of Delrin in both rod and sheet form (very nice to turn) and assumed that it would have to be faced off. It's a bit tricky working with thin pieces, but not impossible by any means.

I would certainly like to try a Delrin mat though as it is one of the few materials I haven't tried for this purpose.
