I'll tell ya what.....
I have been wanting to make one of these babies for years. I have searched the internet and I can't remember the name of the guy who initially posted it a few years back, but he had a great idea. If anyone knows him, or can find him, let me know so I can thank him. I'm not going to post his pictures. I'll just post mine.
There has been several times I needed to saw a twig or log in half. I use half-sawn twigs for molding on top of rustic cabinet doors. I have used half-sawn logs to make picture frames.
One thing I found difficult while sawing the logs in half, was to keep it vertically straight while sawing so it would have a flat bottom. Ya know, you think you're eye-ball method is pretty accurate, until you get done sawing and see how the shape of the branch or log totally fooled your eye. It's especially difficult when doing longer pieces, but best practice is to cut longer than needed.....a lot longer.
The other thing that makes it difficult to cut twigs and logs in half are the protruding branches that stick out of the log. Ya love 'em, you want to keep them, but they sure make it hell to cut a straight line.
I did a Windows upgrade yesterday. Irfanview used to be my default program to view photos. Now Microsoft's Window's Photo Viewer opens my photos. Imagine that. Doesn't seem like I can add a photo right now. Same old shit. Struggling back and forth with Microsoft's take-over of my computer.
