Finally, a chainsaw holder that keeps the bar steady while you sharpen the chain! It is 2 pieces of 2x4, the length of your bar, attached to a piece of plywood, about 1' wide x 3' long. Leave enough space between the 2x4s so your chain can move freely. Next, set the saw in place, position a latch in the handle. I used a dead bolt surface mount latch, shimmed up with spacers. Set the whole thing down on a stump or two. Sit at the other end and sharpen away!
