Cardboard wheel

[blgoode]

I saw a knife being sharpened with a carboard wheel thos weekend. Where can I get one of those?
What other similar methods are there?

Most knifemakers supply houses stock those kits.

compass, carpenters, glue and scissors.

I made up a few using cereal box cardboard for sharpening; I also have a couple using corrugated cardboard for polishing. The corrugated is much softer.

Peter, How many layers are you using for the cereal box wheels and are you sharpening on the edge or the flat?
Thanks

I use a cardboard wheel to strop the edge after sharpening with a used 180 belt, gives a fine polished edge.

I use carboard wheels for my final edge,if used corretly they will put a final edge on a knife that is screaming sharp.
Buy some they last along time and they are not that exspensive

Layers? No idea! I used a compass cutter until I got *really* bored, stacked them onto a plywood sheet with a nail through it (to keep them central) and used wood glue to stick them together. Another sheet of plywood on the top, and stuck the lot in a vice overnight with some G clamps around to help the pressure. Eventual thickness was around 1". Bored a hole through to go on the pigtail on my buffer, spun the disc up and used an old file to true up the disc.

I had used contact cement to glue up the corrugated wheels, but George Tichbourne recommended wood glue instead as it doesn't smear quite so unpleasantly. And he's right.

Probably a poor time:money ratio on doing this, but since I had the time, the cardboard and the glue on hand, it wasn't too bad. Beats taking the stuff out for recycling.

The cardboard wheels have always impressed me.I use a couple of canvas laminated wheels I made using conveyer belt and contact cement. They work pretty good. I power them with 1725 speed 1/2HP,and found they are almost grab proof.They work good for hog buffing and do pretty decent for final polishing if, you go light pressure.I have seen razor edge put on power hacksaw blades by a local buddy using his cardboard wheel. They work pretty quick,too.

what are you guys putting these carboard wheels on? bench grinder?

 

[Nathan House]

I have mine on a cheap 8 inch bench grinder,I bought some arbors to put on the shaft to get the wheel out away from the motor,this will
give you more room to work the knife on.

 

[John Andrews]

Not me.Just a 1/2 HP motor, right on the shaft.

The motor I was using to drive my paper wheels (got 'em from Koval) died - after I dropped it - and I grabbed a 6" Ryobi "Thin Line Grinder" at Home Depot. Took the guards off and reversed the base (5 minutes work) and the 8" wheels fit fine. I wish it was a little slower, but I am getting used to it.

I reversed the base because you want the wheels turning away from you, you work on the top, and you don't want to reach over or around a spinning wheel to reach the power switch.

A quick look with a high-power magnifier will tell you that the softer stainless blades (ie kitchen knives) need a few licks on a leather strop afterwards, there's a really thin, very soft, very flexible, stretched out burr that forms. If you're in a rush, just drawing it across a piece of pine rips it off. Not so much a problem with anything harder.

I think I spent about $28 for the wheel kit, and $40 for the grinder. I also ended up with 2 extra 6" grinding wheels I don't use. Anyone close by want 'em?

I've been using the cardboard wheels that I purchased from Razor Sharp Knife Service at www.razorknife.com about 3 years ago. Its all I ever use and I maybe have $75 bucks involved which included buying an inexpensive Home Depot Bench grinder.
