Not really much information is available on this machine. What I have is from memories, the
machinery itself, and the web.

Here is a link I found on the web:
Here is an interesting read, a must for anyone trying to operate a mill of
this type. Great information, mostly lose to memories. This reference the is the only most complete
I have yet to find anywhere. If you have a circular saw, please save a copy!
Circular Saws and Their Efficient Operation
This particular setup was purchased from the late Mr. Thompson, in
Crewe Virginia, sometime around 1965 or so. A companion planer/edger
was also purchased for a complete setup.
Back in those days,up until maybe 1976 or so, we cut a large amount of wood on this
Mr. Thompson, for many, many years, cut most of the wood in the surrounding towns nearby,
to name a few. Crewe, Burkeville, and Blackstone.
Power was supplied by a McCormick-Deering power unit, likewise
also with a McCormick-Deering 10/10 Tractor. The power Unit
has been sitting in a pasture for the past 30 years or so.
The Tractor has been sitting as well, but in a barn, sleeping.
Power now days is supplied by a Allis WD-45 Diesel tractor,
supposedly rated at 45 Hp on the pulley of 9" diameter, FT-Lbs
of torque is unknown. Tractor is ran somewhat close to full
throttle, given a saw speed of approximately 600 RPM. Mandrel
speed is between 325 (minimum) and 625 (maximum) when powered
by the WD-45 tractor.
The tractor has a 9" pulley, while the driven pulley of the mill is
24", giving a reduction of somewhere close to 3.21:1. So for
calculations, shaft HP available at the mandrel would be close to
100 HP. The sawdust extraction chain drive uses quite a bit of
power to operate, so we take quite a bit off for that as well.
We normally use two Blades. Shanks (inserts), bits are still available.
44", with 44 teeth, insert F,
gauge 8/9, 17/64 kerf.
Unknown as to the speed the blade was hammered to, but as a
youngster, I do remember taching the mandrel for 600 RPM. Per
calculations I have found, this blade feed-rate should be about
242 feet per minute. Bite per tooth about 0.011 per inch.
Horsepower requirements are set about 11 HP per vertical inch cut.
52", with 53 teeth, insert 2
1/2, gauge unknown, and unknown kerf.
We rarely use the larger blade.
I presume, this blade was also hammered for perhaps 600 RPM, but
Currently the mill is down for maintenance. Researching to find a belt
set, for both forward and reverse. The original belts (I believe) were
of cloth type construction, and allowed to slip. Rarely, did they ever
not slip. So new belts need to be able to "slip" and are particularity
difficult to locate.
Two fellows can operate the mill, but I strongly suggest a minimum of
3, but 4 would be much better:-).
1 - Saw Master - Me
1 - Log positioner - My Dad
1 - Board/scrap handler - My Brother
It is a family thing. Of course, visitors and those who enjoy
Manual Labor are
always strongly encouraged to attend!
Here is a photo of the building housing just the mill. The
planer and such is not currently setup for production. Another
project to finish....sigh....
The Original Name Plate!
Picture of the Drive portion, tractor is to the left. Belt
hanging down is for the chain drive.
Mandrel photo showing the pulley arrangement. (With Labels)
Another photo showing the drive section. (With Labels) Here in this picture,
to the top, you can see two electronic guages. One is to show mandrel RPM,
while the other is showing Feet per Minute the carriage is moving.
(Great to keep the carriage moving at the correct rate!)
Another photo showing the drive section, semi side view to show
complete mandrel. Looking closely at the carriage rails, you may
spy the 3x4 steel angle iron, placed to keep the rail set (perctly aligned).
Best upgrade we ever did!
Carriage and complete mill rail set. OSHA was not around in
those ole days!
Here is some photos of the belts. They are truly
antiques! The two belts are different as to type of belt. I
cannot remember of the life of me, what the truly original belts
were. But these two have been inuse since I can remember.
Both belts are 3" wide, but really should be 4" since the pulleys are
4". Replacements will be 4". Never had a problem with the
The "forward" belt is 15' 3" in length!
The "rear" belt is 7' in length
The belts are show, as to the type material they were made from and
These belts use "CLIPPER CLIPS" manufactured by Flexco
and some good training instruction are located
and the same is stored locally here
Any questions, please email
