Once again you come up trumps, Lawrence. It's much appreciated.

I've been looking through TIMTAPE's lapping manual and am sourcing the recommended lapping films. Before then I'll have a go with the fine wet and dry stage, then try that clever light technique.

Am I reading it right in that the tape is just touching the head, so the light on the back of the tape is reflecting whether the bottom or top of the head is touching it more heavily?

My brother also has a workshop so may be inveigled into making me an engineered block.
