Probably too late to help Dan, but let me describe what I did. Using a $50 electric 14 in. chainsaw, I built a Tee from 2x4s, the upright being about 12 in. tall, the crossbar (top) of the tee being about 30 in. Put on a 1x2 diagonal brace to stiffen the whole thing. Drilled (actually just enlarged existing hole) 1/4 in. hole thru the bar of the saw just behind the nose roller. Drilled a similar 1/4 hole thru the side of the upright of the tee about 4 inches from the intersection with the crossbar. Turned the whole thing upside down (crossbar is now a foot) and screwed it to a plywood table with the upright beyond the right end of the table and set back from the edge about 6 in. Put a 1/4 in. bolt thru the hole in the upright and thru the hole in the bar of the chainsaw (with a washer between to prevent contact). Viola! Chain-chopsaw! I tied a cord from the top of the upright to the handle of the chainsaw to limit downward travel (which would cut into the foot) and set a hard stop at my desired length. Feed the wood out to the stop with the left hand, work the saw with the right, park the wheelbarrow underneath to catch the drops. Placed a 2x4 along the edge of the table for a backstop (the saw wants to pull the limb towards you). Working on a left hand lever clamp to keep the wood from spinning. Will post pictures when I get home and can get to it.
