MY LITTLE BLACKSMITH SHOP CHEATS 2018 HOW TO
OK so now we have that engine mounted, and the pump mounted, how to get that fluid to the cylinder so it does not just spray around. You also have to mount the pump either to the engine case or the frame to keep it in place and prevent it just spinning with the shaft. You then have to somehow couple the shaft from the engine to the pump, so one of several styles of coupling is used and the pump is connected to the engine. So now on your frame you make a mount, and bolt the engine down. So you need a pump to make the fluid flow and to take some of the energy from the engine rotating shaft and raise the pressure of the fluid. But wait, it it is not yet split because the hydraulic cylinder needs hydraulic fluid, flowing with pressure to move. In any case the cylinder rod and the fixed end trap the wood between a flat and a wedge and the wood is split.
So a simple frame that holds the cylinder on one end and at the other either the wedge or an end stop. A straight linear push is what hydraulic cylinders do well. So one way is to use a hydraulic cylinder to push the wedge. To have the small gas engine do the work you need to take the relative rotational energy at the output shaft and convert that into a linear motion to push the wedge, or some other way of getting that wedge into the wood with great force. You know that a 12# maul swung as hard as you can will not always split the wood so you want lots of force to push the wedge into the wood to effect the split. From experience you know that you have to use a wedge shaped object to spread the wood from the end to cause it to split. An example say you have only a somewhat small gasoline motor, and want to make a nice portable log splitter. In a hydraulic system, a number of components are used to convert a power source into hydraulic pressure to do a task not easily achieved with the original power source.
