For many years I used an old saw vise to hold chains for sharpening when they are off the saw. The saw vise was originally intended for holding circular saw blades or hand saws for filing, but it fit my needs pretty well...until the cam finally wore to the point that it would no longer clamp the chain securely.
I decided to make up something that would work better, and just used bits and pieces I had around the shop. The jaws are cut from an old fir 2x6 and I lined them with some 1/8 x 1/2" aluminum I had around, a couple of 3" hinges and some over center clamps. I tried to make it long enough to allow me to file three teeth of a 1/2" pitch chain in one "bite". I did add a spring inside to hold the jaws open when the clamps are released to make positioning the chain easier.
