My relative Ken was in need for a log splitter. I made one up for him, using a cheap bottle jack and various bits of stuff I already had lying around. The resulting splitter is foot operated and capable of splitting logs of various sizes.
Although this project falls in the category of Redneck projects, it is still important to think of safety. For example, I did not only look away when grinding steel, but I also squinted my eyes at the same time! *
* Just kidding: WEAR GOGGLES!!!
Step 1: Main frame
For the main upright I used a section I salvaged from a store display unit. It has holes along it's length, which will be useful for adjustment purposes. I also used 25X50 rectangular box and 50x50 square box, which I recovered from other redundant fabrications. I did sketch up the main frame and sliding block before making them. After completion of the frame and the slider, I did not make use of any drawings and made it all up as I went along.
Step 2: Sliding Block
It is the intention to push a log upwards, into a wegde. This will cause the log to split. This step shows the sliding block, for the log to sit on. It will be pushed by the bottle jack and will be guided along the main upright section. In order to get a good fit, I used shims (+/- 0.1mm thick) I cut from beer cans. As it happened, I did need to remove the paint from the upright in order to achieve a good sliding fit. If I were to do it again, I would go for much more of a gap.
