'Dishing' is what I'm measuring and trying to correct. This is usually easy with pucks etc - but sometimes there's also warping which isn't obvious but is visible with a bubble.

With dishing the bubble either moves towards or away from the spindle from perfect centre (north/south). With warping it moves east/west. This is impossible to fix without a vacuum platter. As I can't fix it I only adjust for the 'dishing' effect.

I think I need a life.

How can you 'adjust' for dishing? Any error in azimuth will vary with radius.

Record pucks can flatten slight convex dishing but not the reverse, concave, there are some edge clamps but I've never tried them.

The tunuto mat I use is actually 1° concaved - this along with pucks, a central 0.2mm felt spacer means that I can level and maintain good platter contact with all discs that are slightly dished, both convex and concave. Obviously if you could drink soup from it, no. rolleyes.

If its clean then just stick it on and play it. if its bad enough you will hear it; if not why worry. Lifes too short
