Built this unit to cut tops up to 10" diameter. saw mounts on frame and acts as a chop saw. Using a pulp hook you pull the section forward to a 16" stop and operate saw with one hand. If you have a second person feeding the bed you can really sail. I have probably cut in excess of 100 cord with this and it works tickityboo. Make cutting up the small stuff quick and safe with no kick back or wood movement.
