Thought I would start a new post as I have narrowed things down alot since my original post found here.
Hardest job this will do will be 12-16 inch birch on a 6 way splitter.
Motor likely will be an Isuzu 3KC1 3cyl diesel motor (Will be looking at a couple used ones this week) which is rated at 23HP at 3600 RPM, 15HP at 1800 RPM and max torque is at 52Nm or 38ftlbs at 2000RPM. I was planning to run the final shaft RPM of the saw drive at 7000-9000 RPM with a 12 tooth .404 chain making about (7000*.067*12=5600ft/min)(9000RPM=7200ft/min) of chain speed. If I run the motor at 2800 RPM that gets me right around the 1:3 Final drive ratio so that calculates out to 17.33Nm but realistically probably around 15.
Other stuff
28 GPM 2 stage Hydraulic Pump (maybe an auxillary if enough power)
Auto Cycle split valves with power beyond (have a live deck and infeed that will be integrated)
Manual saw arm (for now)
Belt drive saw
4" x 1.75"Rod x 24" Cylinder
25 Gal Tank W suction filter (Or smaller if the motor has an oil cooler)
Looking for some input as to that motor's abilities in this scenario. Plenty? Not enough?
Bar length suggestions (Was thinking a 21" SpeedMax XL) and a 12 Tooth gear
I have got to this point thanks to alot of input and alot of my own digging, so any advice or comments good or bad are really appreciated thanks!
