Fire Wood Processor

[Black Forest]

That frame looks like it will work well for your intended use. I know you have built your clamp for holding the log while sawing but you might want to investigate a top roller design. When using a firewood processor the first cut and the last cut on a log are the productivity drains on efficiency. The last cut on a log more so. When you raise a swinging clamp style such as you have built you lose control of the short piece that is left of the log allowing it to tip up or fall before it is cut. A powered roller stays in contact with the log the entire time the log is fed to the saw. There is the time factor of raising the toothed swing arm clamp such as you have built, feeding the log forward, lower the clamp and then cut. With a top roller design you just feed the log forward and cut. No loss of handling control of the log. Lots of time the last short piece of log falls crooked into the splitter before being cut if there is not much left to counterbalance the log. This all takes time to rectify therefor cutting into productivity. I have a very simple design of a top roller that is powered by the conveyor system if you are interested to see it. On my firewood processor the height of this top roller sets the height of the splitting wedge accounting for the diameter of the log. It saves a lot of operator fatigue by not having to constantly manually adjust the the height of the splitting wedge.
