Honestly, I don't know, but running it with little tension is what I get from the photos.

My guess is, that you have to run it with the tensioner disengaged, otherwise it won't fit.

It looks easy enough to duplicate out of a chunk of 2x4, just grind to shape.

Since my wife got used to having sharp knives around (she grew up with dull knives), she's gotten spoiled and so when we go out to eat, we *almost* take a couple of our own knives with us - just because we hate having to deal with restaurant "sharp" knives.

A sharp knife is a safe knife.
I like my Sharpmaker too. I also grew up with dull knives, and am very much enjoying learning to use, appreciate and maintain sharp knives. One thing- a strop is a great addition, too. I've run into some situations where there were burrs I just *could* not eliminate, except with a strop.

One caveat about that "sharp knive is a safe knife" thing- paradoxically a sharp knife is only safer if you know what you're doing. Dull knives let silly people get away with bad habits that a sharp knife will, um, bloodily train them out of. (Lending a sharp knife to someone who's never used a sharp knife before- and therefore has lots of stupid habits- can be a disaster.)

That why you always warn them - "Careful, it's SHARP." :D

A person properly schooled in right and wrong is safe with any weapon. A person with no idea of good and evil is unsafe with a knitting needle, or the cap from a ballpoint pen.

I learned on a free whetstone, and still use one in the woods. Dad has a Spyder, and I'm pretty good with it, but my sharpener of choice is a Lansky. I've sharpened everything from a 9" hunter to two-blade broadheads with it.

We do a lot of robotic polishing/sanding on belts, and "slack" is never actually "Slack". There's always tension, but the tension is adjustable by spring or air pressure. We commonly use balance regulators and air cylinders to keep the belts at proper tension. In other words, one roller is on an air cylinder whose pressure is set to, say, five pounds. If you push in on the belt, the cylinder pressure goes up a bit, the regulator valve releases a bit of air, and the belt develops some slack. Back off, the pressure goes down, the regulator allows some air in so the presure increases. I have a dozen or so of these in the field I built myself, but there's also a lot of similar stuff from places like Pushcorp and kalamazoo. They usually have replaceable teflon belt guides which help deal with alignment.

You can just soften the spring on a regular belt sander as well. You'd be surprised how much tension a belt will take. Hell, mine is homemade with a flat side and a slack side which I just turn over when I need to.

For some fun, order some Trizact belts from 3m. They appear to be miraculous in their efficiency.

Anybody know of a source for black arkansas stones that don't cost an arm and a leg? Ideally a bigger stone?

<EDIT> hmm, this is about the cheapest I've found, but it makes me suspicious, as it's half the price of everybody else - is it "Surgical black" or is it "Arkansas that happens to be black"?</EDIT>

AG Russell had some nice ones a coupla years ago, but I practically fell out of the chair at the price. Dan'swhetstones.com gets almost $150 for a 10 inch..

I lucked out when I got my bench stones from SMKW - they were having a clearance sale, and mine had "visual" defects - Ten bucks each, and they work pretty good.
