I cut a decent size maple tree and was able to get three pretty good logs from it but I had no way to mill them, my LongMill was just a wee bit too small so made the LogMill.
The LogMill has no x but over nine feet of y and about sixteen inches of z. It was made on the cheap as all the lumber was salvaged. The only purchase for the build was the eighteen inch bar and a ripping chain for a grand total of $60 U.S.
The sled is driven by a hand winch and a three to one pulley system. The z uses a ten mm five start lead screw that was kicking around since my Dad upgraded his Sainsmart 4040. The LogMill has printed bearings, pulleys, lead screw nuts and some other bits and bobs.
It took about a week to make and today was the first time that I got to use it. It’s not the fastest way to make boards but it worked well and I’m happy with the results. All the boards in the last picture came from the skinniest but longest of my three logs.
I’m tired now…
