A heavy weight will only create a solid bond in the center label area of the record, maybe slightly further. I think a clamp would be as affective preventing movement of both record and mat.
A reflex or periphery clamp should be more affective coupling the music part of the record. I haven't yet located the felt washer.
I suspect a leather mat is a bad idea. The compliant surface under the record seems to be the problem. The record needs to be supported in such a way that allows no movement of the groove.
