Thanks Brent, I tried that, but it was still slow. A little faster
maybe, but not quick enough. And I was reluctant to rub the BHA on the
exposed foundation down the basement. So I let the thing sit until this
afternoon, when I recalled having a couple of Eze-lap diamond paddles,
which our daughter gave me some time ago - and for which I'd found
little use - until now.
I have the black (Coarse, 250X) and the green (Extra Coarse, 150X). I
generally err on the fine side, so I put the 250X paddle to work on the
high spots, and it cut the BHA just as nice - and quick - as can be, a
lot quicker than the 325X ( which may be worn). The white dust that
accumulated on the low spots and on the paddle was so fine, it reminded
me of the floury silt that washes down from the mountains in glacier-fed
streams. Finer than flour, so fine it gets into your pores. And as pure
a white as you wouldn't believe coming off a black stone. I kept a
spray bottle of water handy, set to give a stream, and cleaned the
paddle off with it as the dust accumulated, drying the paddle as best I
could between sessions. As Kurt suggested, the high spots just spread
out to the edges and disappeared there. And low spots which I hadn't
noticed before accumulated enough of the white rock dust to make
themselves visible. So there it is, a thoroughly satisfying discovery.
The right combination of hardness and coarseness, and at an affordable
price point! Now that the high spots are cut back, I'll finish and
maintain the BHA on the Norton Crystalon. Those paddles are worth their
weight in, um industrial diamonds?
I have decided to leave my past behind. So, if I owe you money...I am sorry, but
I’ve moved on.
