I'm in need of some operating info on an old sawmill I just refurbished. Is this the place to ask or where should go to ask the multitude of questions I have? Such as how do I know what HP and what RPM the mill should run at.
Right now I am using the same setup my grandpa used, running the mill with a 1939 AC WC I rebuilt. I haven't gone far enough to check the RPM I am running now.
thanks,bushnellman
 
We can probably help, but need to know the saw diameter, and other details. Flat belt drives are often described in terms of belt
surface speed. If it was working as set up, it is likely close. Jim
 
Run the saw at the speed that it stands up straight and does not wobble.
When you speed it up till it wobbles, slow it down just a bit and try it in a log.
Sometimes the speed it was hammered to run is stamped on the blade.
I had mine hammered to 450 rpm and had plenty of power to pull it.

The best thing is to see what speed your
power unit will run it ideally 500 rpms
on the shaft of the blade but you need a
lot of power to run a 56 or 60 saw
blade at this speed once you figure out
what your power unit will pull then have
your blade hammered for that speed

I have had it running as fast as the WC will go,well full throttle, which brings to mind another question, but first , I see no wobble in the blade, does this mean I could actually go faster, if I had a different power source?
The question that came to mind...is there any way to change the speed on the pulley coming off the WC? I mean it's just the speed of the motor right controlled by the throttle.

A WC seems a bit small for a sawmill. The mills i have been around want over 40 hp to keep the speed up.

Our mill is similar and a super w6 is about minimum.

It runs great with a 60hp steamer on the belt!
 
As said below, we need ro know the size of your mill. I once worked for a mill outfit in S Mo round W Planes Mo. They had at least 2
set ups, and I worked both, ans an end man, edger, and setting the logzs on the carriages. One was run by a BIG cat engine, straight
pipe. The other, same size was run by a AC stationary engine like they used to use on rides at circuses.
