The Infamous Parks 12” Planer.by Doug Rewerts e-mail: dkrewerts@alltel.net
Special thanks to Keith Bohn for contribution of numerous documents and his article “Notes on
Dating a Parks Planer” which was the seed for this effort, Keith Rucker, Jeff Traeger, Robert
Vaughan and many others for much assistance in developing this article.
Early 1980’s Parks’ literature stated that over 50,000 12” planers were in use in shops all over
the world and I would submit that many of those planers are still in use today. Some of us
who own one of these planers would like to know how old our planer is, or in other words
when it was manufactured. After purchasing a Parks planer in late 2003, I became somewhat
obsessed with finding out how old my planer was. Unfortunately, to my knowledge, a chart
correlating serial numbers to date of manufacture does not exist for Parks’ machines. So, with
the help of several other OWWM members, I began the quest to find out. Informally, we noted
early on that there were a few obvious differences in some planers, such as changes in the
gear box cover from three humps to one hump. After staring at lots of catalogs and photos I
began to make a list of differences. From there I developed a survey to collect information
from Parks’ owners regarding specifics of their planers. The purpose is to gather enough
information to establish a correlation between serial numbers, changes or variations in the
planers and a time line. Thus we would be able to establish the date of manufacture or at
least approximate it. That survey follows this article.
First, a little bit of history. Parks 12” planers were manufactured as early as late 1936, or
perhaps slightly earlier, until 1989 when Parks Woodworking Machines went out of business.
Our first evidence, in print, of the 12” planer is its inclusion in an undated Parks Catalog No.
37, which we think was published on or about 1937. Next, we have an undated Parks Heavy
Duty 12” Planer brochure that includes a copy of a letter dated Nov. 1, 1938, from a satisfied
customer stating that they “have had the planer in constant use for the past two years.” That
would place manufacture as early as late 1936. To further place the origin of the planer in the
late 30’s, we know that Sears included the planer in its 1938 catalog. Sears continued selling
the planer through 1959. In the 1960 Sears catalog the Parks planer was replaced by the
Belsaw planer-moulder. Although the Sears catalogs have been a helpful resource, one
problem with using Sears Catalogs to identify changes is that there were no catalogs
produced for the years 1944-1947 due to WWII. So when something shows up in the 1948
catalog it actually could have been several years earlier.
Mechanically, it appears that there were no differences between the Parks and the Craftsman
planers. Cosmetically, the only differences between the Parks and the Craftsman appear to
be that Craftsman Planers had Craftsman logo and model number tags rather than Parks tags,
and the Craftsman Planers were painted a bluish grey rather than the plain grey of the Parks.
Also, the Craftsman planer only came in the basic model, without a stand or motor (same as a
Parks Model 95). In 1956 Sears began offering a 12 gauge steel stand and belt guard as
options. With those two options the Craftsman planer would be identical to a Parks Model 97.
There were six model versions of the Parks planer. The No. 37 Catalog shows only the Model
95, the basic bench-top planer without motor or stand. The c. 1938 Parks Heavy Duty Planer
brochure includes the 95, the 96 which is a direct drive version, and the 97 which is a 95 with
a stand and motor, later to include a belt cover. A 1952 Parks Planer-Jointer brochure and
parts list includes the 95, 96, 97 and the Models 10 & 11. The Model 10 is the planer-jointer
combination machine and the Model 11 is the same with a stand and motor. The 10 & 11 may
have shown up earlier than 1952; that is just the first printed evidence I have uncovered. And
finally the Model 98, a belt driven planer with a rear mounted motor appeared in a 1984 Parks
catalog, according to Dana Batory in his book,
Vintage Woodworking Machinery, Volume Two.
There were/are at least three different model numbers for the Sears badged planers:
112.1901, 112.23490 & 112.23491. I have yet to establish a reason for the three distinct
numbers. The 112.1901 model was the earliest, the 112.23490 next and the 112.23491 the
final model. At some point we may be able to establish a correlation between the model
numbers and time or changes in the machine, but a correlation is not evident at this time.
The Parks Model 97 Planer was sold with three different stands as time evolved. The first
stand was a very graceful cast iron stand with sides that flared out toward the bottom. Later
the planers had a cast iron stand with straight sides that sloped out towards the bottom. Later
stands were also sloped and straight sided but made of fabricated sheet steel. Sears offered
the fabricated sheet steel stand beginning in 1956 according to their catalogs.
Here are the items/changes identified so far from studying Parks catalogs, brochures, parts
diagrams and lists, Sears & Craftsman Catalogs as well as 20 or so surveys submitted by
Park’s owners.
In Parks Catalog No. 37 the main frame of the planer consisted of a single casting, there was
no throw out lever on the gearbox and there were what appeared to be hand knobs on the top
of the roll bearing studs instead of the familiar tall looking hex nuts. The gearbox cover
appeared to sit on, or as I soon learned, snapped on to the gearbox. Also notable was that
the table raising shaft went through the left side of the base casting and was secured with a
collar. There was also a flat steel bar bolted to the front of the two side castings in front of the
in-feed roller. I note those items because changes soon appeared regarding them.
As you will note from the above pictures, several major changes are apparent in the 1938
Sears Catalog photo. The frame is now clearly consists of three separate castings – two sides
and a base. Although we do not know the reason for that change, we can guess that it was
done because it was easier and perhaps cheaper to cast the three separate pieces than one
very complicated casting. The gearbox now came with a throw out lever to disengage the
feed rollers. The table raising shaft no longer penetrated the left side of the base casting and
the flat bar in front of the in-feed roller was gone.
We know that the gearbox itself was originally cast iron, but at some point fairly early in its
history it was changed to cast aluminum, probably because the weight of the CI gearbox
caused excessive wear of the gearbox where it hangs off the cutter head shaft. We have
identified three versions of the gearbox cover. The original snap-on cover, as seen in the
above picture in Catalog No. 37, was in use until sometime between 1943 and 1948 when it
changed to a bolted on cover according to Sears Catalog art work. If the Sears’ art work is
reliable, then it appears the multi-hump cover changed to a single hump cover sometime after
1959 when it last appeared in the Sears Catalog. I have heard one or two reports of a cast
aluminum gearbox cover, but have not confirmed that an aluminum cover was ever made.
There are at least three variations of the base casting. The original around 1936, a second
appeared in the Parks Catalog No. 37 as well as the 1938 Sears Catalog, when the sides and
base were separate castings and the table raising shaft no longer went through the base
casting on the left side, and another by 1948 based upon the 1948 Sears Catalog, where there
were additional changes in the same area of the base casting.
At some point the table casting was revised. The change is not evident from the top of the
table. On the underside of the table the pattern of the reinforcing ribs changed from a waffle
or grid pattern to an “X” pattern.
At some point an adjustment screw was added to the front of the shaving hood, I think at least
by 1948.
By 1957 the cutterhead had been modified to include jack screws to improve adjusting the
knives. The first evidence we have of that is it being noted in the 1957 Sears Catalog that the
“planer now has cutter heads with jack screws for micro adjustment.” That may also be the
time when the gearbox got a grease seal at the in-feed roll.
At some point the table roll bearings were improved to include bronze sleeves. Of the two
(1949 & 1980) parts lists that I have, neither shows the bronze sleeves, yet they show up on
the current parts list of D. C. Morrison Co. I happen to have seen both versions so I know they
exist.
There are at least two variations of the depth of cut pointer – a bent steel wire or rod version
and a bent flat aluminum version. At this point we don’t have enough information to know if
the pointer is significant in the time line. However, based on a limited number of planers
surveyed to date it appears that the steel pointers were used on early machines, to
approximately serial number 5,000.
The table gib screws and lock nuts have several variations as do the hex adjustment nuts on
the roll bearing and pressure bar studs. With a limited amount of data, it appears that earlier
planers had 1” tall hex nuts and later machines (those with serial numbers approx. 30,000 and
higher) had shorter (5/8”) hex nuts.
There are several variations in the badging (logo and model number tags) of the Craftsman
planers and of the Parks planers. Parks nameplates were typically a 2” x 4” aluminum tag with
red and black on silver, or black on silver. Some planers have a metallic sticker of the same
size instead of an aluminum tag. So far, when we have seen the metallic sticker it included
the serial number stamped on it. It appears that the metallic stickers may have arrived at
approximately the same time as the short hex nuts, at about serial number 30,000.
Sears badged planers typically had a Craftsman logo tag and a Sears model number tag. The
Craftsman logo tag was usually found on the front of the base and the model number tag on
the rear of the base. Sometimes the logo tag was on the top of the planer and then the model
number tag would be found on the front of the planer. There were two years (1942 & 43) in
which the Sears Catalog showed the planer without a logo plate, but it sported the word
CRAFTSMAN in large painted block letters on the front of the base and the model number tag
was on the rear of the base. Of all the Sears catalogs, only the 1955 catalog shows the
Craftsman logo plate on top of the planer, but it may have been on the top in earlier years if
earlier Sears Catalogs were using old art work.
Serial numbers can usually be found on the upper front machined face of the right side casting
on both the Parks and Craftsman planers. However, some Parks badged planers had the
serial number stamped on the Parks nameplate or a metallic sticker and not in the frame. We
have noted a few planers without serial numbers, perhaps only because the nameplate was
missing.
Somewhere in the life of the planer the cutter head bearing caps were strengthened by
thickening the ears on the cap.
Although the above information begins to document changes vs time in an overall sense, to
further define a timeline we need to acquire information on many more planers You can help
us by submitting information about your planer(s) or others that you may have access to.
