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.
There is a Firewood Cord Calculator available in the Resources Tab (top of the screen). I think these could be implemented in a similar way if you can provide the formulas. Don't know if Grizz wants to go that way with them, as it would probably require writing a little calculator web page for each. But if you could lay out the formulas in a document form, that could also be the resource itself, until such time the calculators were implemented (PM me if you need help with that Grizz).
I have added a log to cubic feet/cord calculator at the bottom of the cord calculator page. It is in "beta" and is an unfinished project, but it does work.

Volume of a Holzhausen: π r² (h(base) + h(top) /3) Divide by 128 ft³ to calculate # of cords! :stacke:
I'll split and chuck into a pile, more longer than round. To estimate what I have as stacked I use the equation for an elipsoid,,,,the pile is kinda egg like. With that value I divide it by half, for half an egg. Then I multiply that by 70% to account for loose stack and not being quite an elipsoid. With that, I divide by 128 to get the number of cords. It gets me close enough so I can stop getting wood to fill the shed and turn my attention on getting stuff down in the woods for the following season after or hopefully further.
What I need is a formula to tell me if I have a full cord in my dumptruck without having to stack it to measure it....
