Just replaced a vertical shaft engine on a log splitter. Seems to match up perfect on specs except for the throttle. The new engine is designed for a lawnmower so throttle would be attached to a cable on handlebar. But obviously no handle bar on log splitter. What could we attach so we could regulate the throttle? The old engine had a lever that pulled back (choke position) to start and then moved into rabbit position to run with ability to speed up or slow down. Thoughts? Suggestions?

I just put together a log splitter for my son-in-law using various junk parts he gathered. He had acquired an Enerpac Hushh Pup electric pump powered by a 1 horsepower electric motor running on 120 volts. A hydraulic ram 2 inches in diameter and about 3 1/2 feet long came attached to the pump. It works quite well, although it is a little slow. My job was to attach the ram and the pump to the leftover portion of an old log splitter that is an "I"-beam with a slider to push the wood and a large knife to do the splitting. Another part of the job was to mount it on a set of wheels from the front end of an old riding lawnmower. All of this sounds rather simple, but there has been a lot of thinking, cutting, grinding, fitting, and welding to get all of the details as close to right as possible.

Sure, the problem you will face is if the engine has a vertical drive shaft.  You're going to have to use a pump that can be driven by a vertical shaft or you will have to convert the vertical drive engine to a horizontal output in some manner.

.  Many (most?) small hydraulic pumps will run in any position.
.  Shaft orientation should only be a problem with pumps larger than what is required to drive a DIY log splitter.

Pick out you actuator and them see what the requirements are for power.<br /> <br /> <a href="http://weldingweb.com/showthread.php?t=23835">Here's a great link to a welding forum</a> and the post is talking about diy log splitter. The op wants to use electric but they digress into talking about gas powered. They figure 5 horse will make a good splitter.<br /> <br /> There's a link there for a good supply house for parts. You won't find what you need at the local hardware store but maybe the lawnmower and tractor shop is if it's a good one.<br /> <br /> Do plenty of planning before you spend a single dime on parts.<br /> <br /> Good luck and this sounds like a great instructable even if you only go to the planning stage.<br />
