slab roller grit?

Help!

I'm having the same problem as Karen with her used Bailey slab roller,
However mine is a home-made version of the electric Bailey. The rollers
on mine will not draw the canvas through(with or without a board). The
guy at Bailey said that there is an epoxy coating on the rollers with
silicon carbide grit on it to provide tooth. Bailey will not sell this
stuff (They used to, but application problems deterred them--now they
just sell replacement rollers).

Does anyone out there know a source for this or any abrasive epoxy
coating?

Can anyone who owns a Bailey describe how coarse the grit is on the
rollers compared to sandpaper grit? (400 grit, 120 grit, 60????)

Would coating my steel rollers with epoxy paint then rolling them in
silica sand work? Any suggestions?

Dear Sam:

Call Bailey and ask them who makes their silicon carbide paper and ask them
what grit they use.

I ordered Silicon Carbide sand paper for my belt sander through Sears
Roebuck. You might ask Sears the name of the company that is manufacturing
their paper and they might be able to sell you the stuff or point you in the
right direction.

I can't believe Bailey is not selling the paper any more. If that's true its
disgraceful to make someone buy new rollers. I'm appalled at that policy not
only because of the greed factor but also the environmental concerns of
making you buy something you don't need. Talk about waste!

Regards,
June

Try any good epoxy repair material and dust over it silicon carbide grit I
guess about 50 mesh. Try your local cement contractor supply and ask for
silicon carbide such as they use for nonskid concrete or terrazo.

''l HAVE A DRIVE 40'' BAILEY AND HAVE NOT USED IT FOR YEARS FOR TWO REASONS
1.I DID NOT SEE ANYTHING IN THEIR LITERATURE THAT SAID IT IS IMPOSSIBLE TO
OPERATE IT ALONE BECAUSE OF THE SAFETY FEATURE.I GOT MY SON-IN-LAW TO HELP ME
ONE DAY AND DIDNOT HAVE ASSISTANCE SINCE. WHEN I CALLED BAILY TO GET A WHEEL
FOR IT THEY DIDNOT SEEM COOPERATIVE.SEEMS YOU CAN UPGRADE FROM WHEEL BUY NOT
REVERSE.2.AFTER SITTING IDLE A YEAR OR SO WHEN I GOT HELP NEXT TIME THE GRIT
ON THE ROLLER WAS ALL OFF OF IT.SEEMS IF THIS PROBLEM IS WIDESPREAD THE
COMPANY SHOULD HAVE SENT US A NEW ROLLER GRATIS OR RECALLED THE THINGS? I
WAS SORRY I SOLD MY BRENT TO GET IT JUST BECAUSE I WANTED INFINITE CONTROL
FOR THICKNESS AND AUTOMATION TO ROLL HEAVY SLABS.

You may want to try getting a strip of heavy duty cloth backed abrasive
with a grit of 36 or less. I have seen the Bailys and what they use
looks to be in the 36-40 range. You could try to apply the strip
abrasive to the roller in a spiral pattern from one end to the other
using a strong epoxy adhesive. That should allow you to use the slab
roller for a while longer but be aware that the abrasive will wear off
after a while just like the original stuff did. Any time you try to
rely on an abrasive that is glued to the roller you are going to get
wear after a while and slippage as a result.
If you get tired of fighting the wear problems you may want to consider
getting a slab roller with a permanently impressed pattern on the
rollers that will not wear out. Something similar to the method used on
the North Star slab rollers should last you a lifetime.

Best of luck

I am wondering if lapidary polishing grit is silicon carbide. If so, it
can be had from lapidary supply.

Does anyone know?

from the company I would try one of the following:
1. Wrap the rollers with the adhesive backed "sandpaper" sold to provide
traction on diving boards and deck steps. If this doesnt work it should be
removable
or
2 (caution permanent solution or permanently ruined) Take rollers to machine
shop to have them knurled. (texture similar to checkering cut into stock of
firearm)
Good luck and think long and hard before you do something suggestion # 2,

Maybe you can sell the Bailey as well and get enough out of it to buy
one of
big North Star slab rollers. They have the infinite control for
thickness
that you want. I know some people do not like the idea of having to
adjust
each end of the slab roller individually but at least when you want help
with a problem North Star answers you promptly and works to keep you
happy
even after the sale. Another plus is that the Knurled Rolls do not have
the problem of wearing out like the glued on grit used by Bailey.
Thirdly,
you should not have the problem of needing to get an assistant to help
anytime you want to operate the slab roller. I've used several of the
North Star slab rollers (Large and Small) and found them easy to use.

Stress CAUTION on attempting to knurl the rollers on the Bailey. The
rolls are
manufactured of a thin walled steel tubing that may not have enough
material
to accept a knurl. It may also bend the roll if not done using a pinch
knurl.
Be sure to talk the entire thing through with the machinist before
attempting
to do this. BTW, do NOT skimp on the cost when getting a machinist to
perform
this task. A hobby machinist may not be your best choice in a case like
this.

Best of Luck
