Hi Grumpy,

I have used exactly the same method you have used and that is 400 wet and dry folded so as to resurface both sides at the same time, I'm going to use a magnifying glass and have a very good look at them and see what's happening but it very much makes sense what you mentioned about parallel surfaces.
I am just wondering if new points are still available as I'm sure that there wouldn't be that much call which would not justify them being still manufactured in todays age of the more modern stationary engine.

Anyway I'll have a better look over the weekend and report back.

Thanks again Grumpy.

Cheers,
BB.

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
