The good news is that my rollers coated with the Sherwin williams epoxy
with the bondex additive definitly pulled the canvas through the
rollers.
Since I've never used a Bailey slab roller, I can't compare my results
with one. I don't know, for instance, if the epoxy I used is compatable
with Bailey's coatings. But it does work for me on my home-made
electric
machine on which I used clean steel rollers.
The formula I used: 1 qt part A, 1 qt part B, 3 cups of abrasive
would've probably been better with far less of the abrasive. I used so
much that it tended to clump together in little hills. These left a
slight impression in my slab when I used a thin canvas. I'm sure 1 cup
(or less) of the stuff wouldv'e been plenty to get an even spread.
Also, I used a 1/2 inch pile paint roller to apply, and one not so
fluffy would do better I think. If anyone tries this, be sure to test
it first, though. A fairly thin coat would be preferable. The more you
go back over an area, the more the abrasive tends to clump, so 1 or 2
thin coats would give a better result.
I filed off a few high spots, and the slabs produced are fine for my
uses--sculpture, tiles, architectural stuff using 1/2 slabs. I'm not
sure how very thin slabs would do. Also, my machine moves the slabs out
pretty fast. I have no idea how fast the Bailey electric machine
pushes out the slabs, but mine is about 1 foot per second. This, too,
may have an effect on the surface of the finished slab.
Whew! This thing sure could eat up some clay fast!
