What can be done about the slow operating speed of the chainsaw?
I designed the processor to be constructed as inexpensively as possible. For that reason, the original prototype machine was based off of a 10 hp. engine operating a 16 gpm pump. This runs the chainsaw at approx. 5000 rpm. A larger engine can run a larger pump. A larger pump can handle a larger hydraulic motor for the chainsaw. In essence, it comes down to an input cost issue. To use this plan to make a processor that will cut as fast as a regular chainsaw is possible. However, the increased engine size, and hydraulics can add well over $1,000 to the construction cost. This increase, if you desire to do it, requires no changes to the plans themselves regarding the structure size and welding, only the use of different hydraulic components. In addition to this, a larger sprocket size can be obtained for the chainsaw drive from nearly any chainsaw supplier. The prototype uses the standard size for small saws: 24 inch or smaller bars typically use 7 tooth sprockets. A larger-diameter sproc
