Somewhere in my poking around I saw the Stihl has something similar with tubes bent in a U.I just build a jig out of 2x4's that can be folded and moved to whatever site. Build whatever intervals you want into it, but I like have 2 posts per section to hold the wood better and a V seems to work better to funnel the wood down to keep it from spinning or jumping too much. I also added a section of plywood to one end to butt the limbs up against. I stack them in there, cut 3 times or 4 depending on length and then grab wood without bending over and move to appropriate stack, etc. Works great - but I DON"T HAVE A PIC!!!! I'll get one
