I can't help much with the oversize lap. Mel did describe how he does that.
I have let a full size lap go oversize as I was working and I guess it got
to about 1/2" larger than the mirror and it sure did help the edge. But that
was well short of the 6 to 5, lap to mirror ratio that Mel talks about.

That is what real mirror makers do.  They try things.

You are not the first to have the pin hit the mirror.  And you can have a
stop but depending on the arm, I suppose it could fall and flex beyond the
stop...  The main thing is learning that you really have to be careful with
any thing that will be over the mirror surface. And anything that does not
have to be over the mirror surface should not be allowed to be there.
Screwdriver in your pocket?  Or eyeglasses?  Empty your pockets if you might
lean over the work at some time. And the eyeglasses could be on one of those
straps so that should the fall off you face they won't reach the glass.

The dispensers of grit or polishing agent are best in plastic containers,
and if you use a brush for applying slurry either use one that has no metal
surfaces that could come into contact with the glass. You can tape over the
hard surface of such a brush.  I say that because I like to use a horsehair
brush.

Have a routine that you use with the arm that if done the same way every
time will not allow the foolish mistake.  And don't allow idle talk with a
friend to distract you when doing the routine.  Stop and tell them you need
to pay 100% attention.  And let them know the rules.  I have seen a friend
drop the pin onto someone's mirror. Worse, the maker had already done that
once himself. They, both of them, did not realize the ease of making that
kind of mistake.

Once burnt, a lesson learnt.


Just some suggestions.  Don't know where I got those ideas from.

	We'll be going back to #120 to get rid of the crack.

we've both been thinking about mels idea of using an oversize lap to keep
the edge under control. An 8" as I recall would use a 9.5" lap One thing has
me puzzled though. The 1/3rd coc would take the glass ALMOST to the edge of
the lap thereby avoiding the edge of the lap. Is that correct

Lessons we learned from the previous sessions on the mirror are


#4	I've GOT to get a better arm stop for the machine.


Cheers
