So, I just posted a response where someone was looking to resize their pump on their splitter to get more speed. I attached a link to a place that has a cycle time calculator which, I assume will help him. But maybe we could put a sticky up somewhere that has a bunch of these formulas available? Things like... 1. Cycle time calculator 2. HP to pump size calculator 3. Weight per cord or cubic feet for various wood species 4. Board foot calculators for the sawyers a. BF per log b. BF per lumber size 5. Weight per log by species 6. Etc.
