I have been spraying Benjamin Moore's Impervo. It is a water borne
acrylic. After a lot of testing I can now get a very acceptable
finish. The equipment I have is a 4 stage Fuji with a gravity feed
gun. ( Don't let the gravity feed notation fool you. There is a tube
that comes from the turbine and into the top of the cup to pressurize
it.) A nice feature of the gun is that the cup can rotate relative to
the gun, so when the gun points straight down, the cup can be
positioned straight up.
In any case, I have found that adding 10% water and a bit of
extender makes a world of difference in the finished product. I have
also found that adding too much water sprays well but causes the
"satin finish" to be flat and chalky looking. Too much water can
destroy the final finish!
Well there I was, wondering how sharp my band saw blade was, so I
started up my band saw, pushed my thumb into the moving blade, then
pulled my thumb back. When I saw the blood pouring out, I knew the
blade was still sharp enough.
Then I said to myself, Hey Dumb Dumb, If you had the blade guard down
where it should be, I wouldn't be bleeding. That is what happens when
we get complacent, and do not take the time to do it right and safe.
It is healing, and luckily I didn't loose the thumb.
In my shop, I have the plaque of Dope.
On the exquisitely startling occasions when I've
qualified for that title in full capital letters, I
imprint my blood type on said plaque annotating
the fail with an inscription.
For a long while, I had two
tortured objects affixed representing operations
that stuttered a nanotick off full doom. Finally,
some horror fan got them for Xmas.
Funny how these kind of things keep memories
from going ghost.
But, I am afeared Grauman's Chinese may be
preparing a lawsuit.
Thanks for the report along with wishes
we won't have another one.
