I really love my paper wheel system but I cannot get the grit to stay on the wheel. I am using a wood glue, coat with a thin coat and the sprinkle the grit on to it and then pat with my finger a little bit. I let it dry overnight, and wax prior to use. First couple of blades it works like magic, after 4-5 most of the grit is gone. I only use it to raise a burr the bevel is already set. Do I need a different glue??
 
haha first timer - I clicked the thread and just saw your signature and was thinking... wow what a jerk! :) haha then I saw the actual reply.


Patrick - I've had good luck with Elmers glue, and that's what my paper wheels say to use in the instructions; have you tried that? The wood glue I have is more of a tacky consistency which I don't see holding grit at all. I think the Elmer's picks up the grit and wears away along with the grit as you grind, vs the wood glue which lets the grit go when stressed... I could be talking out my A, but it seems to make sense.
 
I too use elmers and apply as you described. Lasts for 4-6 months for me that's probably 50 or more sharpenings. Richard J is the guru. Might want to drop him a PM.
 
Wood glue is made to bond wood fibers. Casin glue (Elmer's) is going to dry harder, and last longer as a grit carrier.
 
I use Elmers,but i have to admit mine usually comes off in smaller sections and doesnt last like a new wheel.I usually just buy a new set because they are pretty cheap and last a long time.Ive pretty much gone to using the belt grinder then finishing on the polishing wheel with white compound.
 
My suggestion is to toss the grit wheel, use a belt to cut your bevel, and use the polishing wheel to remove the burr - one pass per side (max) using some decent pressure.

IMO those grit wheels are nothing but a pain in the ass.
 
I agree. It is also harder to keep the right angle with the curve of the wheel. I use a new belt, fairly slow speed, selecting grit size depending on how dull the edge is finishing up with a high grit then onto the paper polishing wheel.
 
I use the belt when needed and the wheels when needed. I do what you do except I don't pat the grit down once it is applied. I dust it, slowly turn it to collect the excess, and leave it to dry.

You also might be putting on too much wax. Put a file on it to clean off the wax and you'll get to fresh grit. That's what I do anyways.
