So I have had a handful of short "logs" waiting to get milled with my 17" Grizzly, and I finally got around to making a sled. I grab these whenever somebody takes down a good tree and I happen to be driving by. I hadn't seen this method used to secure the logs to the sled, so I thought I would throw it out there. It worked fantastic even on a 36" x 14" round and the strap makes it very easily adjustable and very secure.
It is pretty self explanatory, and I can't say I would change much. I made this one 4' and the base 8" wide.

Here it is with a short piece of birch.

Watch your straps

A couple of 8/4 pieces of sweet gum. Nice and straight.
