Finished up the arm that the bar mounts to and the chain tensioner.

Greg, have you mentioned how you plan to power the saw? (memory is the first thing to go, or is it the second?

hydraulics is the way to go, the feed conveyor, and the cylinder that rotates the saw bar is powered by hydraulic.

I think all the commercial units are hydraulic driven, but I need to be different. Between the pump and motor your probably loosing half your power to heat, plus 7400rpm hydraulic motors get real expensive. Going to set it up with a belt drive from an electric clutch.

Sorry to be a nitpicker Greg but, what drives the clutch?

Steve, Im planning on using that Wisconsin to power the machine but and there's always a BUT, some cuter than others mind. All the commercial ones have much bigger engines, 40 to 80 hp range might be a manly thing as I can't see where the power is used. Oregon has charts on everything about their Harvester chains, 10 hp should give a really good material removal rate, and the splitter which won't be working when the saw is should only need maybe 8 hp.
Anyway, in case the 14 hp isn't enough I'll run a driveshaft off it to a jack shaft where I can run one of the two pumps, then belts to speed up a second jack shaft that will carry the clutch and the second pump. If I need a bigger engine it would be a lot easier to convert with the driveshaft drive. The Wisconsin revs at 2800 RPM, which will drive the small pump for the cylinders and such, the second jack shaft will run at 3600 RPM for the clutch and splitter pump. Then speed up off the clutch to 7400 RPM for the saw to give a chain speed of 8000 feet per minute (Oregon's recommended speed) Probablty a lot more info than you asked for but thats the current plan.
