cardboard wheels

**son_of_bluegras** · 11th May 2007, 01:40 PM

Greetings

I made a reference to cardboard wheels in a thread on sharpening and was asked for further detail. Going on the premise of "if one ask several are curious", I'm starting a thread on these wheels. If you have any questions ask away; if I don't know the answer, I can make something up.

We'll see how much translates from American to Aussie.

I bought the wheels maybe 2 years back as a 2 wheel set. One wheel is gritted (has SiC powder glued to it) the other gets loaded with rouge. What I have are some 6 inches diameter X 3/4 inch thick (~150 X 20 mm).

I understand they aren't available on that side of the world. Maybe you could make your own. I don't know what glue is used. The cardboard plys are about the consistancy of the cardboard t-shirts are folded. I think the real problem would be getting them true enough to not vibrate.

They work fairly well for edges with already established bevels and the rouge wheel does a bang up job of polishing the edge (makes chisels cut like nobody's business). Care is needed to not overheat the edge (wax can be used on the gritted wheel to help and keeping a good bit of rouge on the other wheel helps). Of course it leave the leading edge concave which may or may not be as durable as a convex leading edge. (I prefer hand stones for my personal knives but use these for speed when I sharpen of someone else.)

Thanks for putting it up, Ron.

Do you know what grit the SiC powder is? What sort of wax is used on the sharpening wheel?

I believe the sharpening wheel is unslotted, but the honing wheel that takes the rouge is slotted? How big are the slots & how many?

When you get a sec, could you please post a few closeup piccies of each wheel.

Thanks for the info...........cheers..............Sean

I used white pva glue painted onto the round cut cardboard disks until I reached my desired width.
Clamped until dry; drilled centre hole.
Ran it on a bench grinder and smoothed with a rasp.
Coated the outer rim with white pva glue and then tipped silicon carbide over the outer rim while slowly rotating by hand.
I had some newspaper underneath to catch the spill

Gday Keith, sounds good, like to see piccies of your setup too

What grit did you use, & where did you get it? What sort of wax do you use?

What tools to you use it on, & how would you compare it to grinding / beltsanding , etc

Details, details...

Cheers.................Sean

there was some discussion about something similar in the past & the upshot was that MDF was a realy good proposition particularly if you could get it in 25 or 32mm

cheers

For those lucky enough to live in Brisbane, Reverse Garbage at West End sell 12mm wheels, about 100mm diameter for something silly like 20c each. They also sell lots of other goodies - cheap dowel for instance. and lots of bits of pic frames, old doors, all recycled.

Don't know what grit the SiC is, but if I had to guess it leaves similar marks as about 300 grit sandpaper (maybe 400). The was has the consistancy of candle wax, similar to beeswax without the beeswax smell.

The gritted wheel is unslotted. The honing wheel is slotted, never counted the slots but the are about what you'ld expect from a band saw blade and space roughly an inch apart (roughly 25 mm).

will see about the pics (can't say when it may happen).

I did count the layers of cardboard when I was in the shop today. Came out to 14 layers which puts each layer at just a bit over 1 mm.

from what I understand there is no need to have slots at all.
the cardboard/mdf should be plenty porus to hold the compound.

anyway both mdf and cardboard are pretty abrasive in themselves.
