At this point, however,I have just pressed my lap back to being a full
6", so I will give the shorter strokes a try, just to see how it goes.

Thanks for your advice, it is a great help to have access to someone who has done it before.

David,
You have excellent advice from Cristian. If however, all that fails, your lap might be too soft and the edge area is burrowing in slightly with each stroke. I have found when making my mirrors that laps can be of ideal hardness when you make them, but as the weather warms up they tend to go soft on you. I ended up making 3 laps over 6 months polishing my last mirror, a 10 inch. Polish for short intervals (less heat generated in the lap) and press heaps.
Good luck; patience and determination will get you there.
