Hmm... Not sure about that PP, I just had a thread pinched due to hot chicks me thinks...bikini clad ones even. It was a dumb thread anyway so no matter.
Re the mill: The rig just slides on top of the ladder for the first cut just to get a true surface. The chain bar is cutting the wood under it. After the first cut you ditch the ladder and use the freshly cut flat face you just made as your sliding surface. And the chain bar now cuts a new kerf below that...about 1/2" is the thinnest board you can cut with one of these rigs. I cut all my raised bed boards 2".
I found a picture of the big mill. In order to use its full potential you'd have to have about a 76" chain bar and remove the saws spike bars. I can cut about 1/4" per second at 30+ inches wide. So just over 11 min to cut a 14' slab..... if you can last that long!.
Beauty of these mills is you can cut the log right where you fell it....as I did
The last picture here is the same log as the first picture..but with the small mill ..It maxed out way before getting even really started on the log. The first picture is the first cut with the bigger mill on that same log.
So Travis I hope this helps you? FWIW they are called Alaska Mills...easy to toss in a plane and head out into the bush.
PS I'm in Washington not Oregon.. way better sailing up here...
Now to return to our regularly scheduled programing....I'm excited about the sausage Ratatouille!
