... the process I think it will be more fun for you and me to
document a few complete restorations. By the time I am done you
will have experienced all the basics and more. I will try and
reduce the strain by using many pictures and a little less
preaching. As we move along please be conscious of the order of
things and forgive me for a little redundancy. It will be for a
Disston No. 112
Recently I acquired a No. 112 Disston that is a bit distressed,
at least the plate certainly is. The Handle is still in decent
shape but is missing some of the screws. This is what we have to
Not a bad looking saw at first glance though the plate is a
little worse than I normally like to work with. It is a bit
rusty and does have some pitting that will forever be part of
The etch is not visible at this point but may show up after
cleaning. This saw will never be a show piece but I think I can
bring it back to life and make it a good user. The back side
shows similar condition.
This saw has a 28Ē tooth line with 5 points per inch and
obviously started life as a big bad rip saw. However, in its
present condition it would be better suited to trim the lilac
The teeth have been filed with fleam and the tooth line is a bit
wavy. The teeth are not evenly spaced and the rake angles are
all over the map. The best feature of this saw is the handle. It
only has one small flaw that needs repair; a chip out of the
back of the hook.
A bit more study of this thing shows a still very straight flat
plate that also feels stiff and taut. A good sign that this is a
real No. 112 plate. Next I remove the handle and set it aside.
Itís time to clean the plate up a little and get a better feel
for what might be best for this beast.
I used 320 grit wet / dry paper wrapped around a hard wood
block. Always sand lengthwise in long straight motions. I use
mineral spirits as a wash and do this work in a shallow wooden
tray. I donít get carried away with this; just enough to break
up the surface rust and clean away the foreign crud. Next I dry
the plate with clean rags so I can see what I have. I will
further clean the plate later.
I am still trying to decide what is best for this saw; keep it a
5 point rip or maybe not. Looking at the tooth line it is
apparent that no matter what, some plate height will be lost.
In the picture above the teeth area is coated with layout dye
and scribed with a straight line the full length of the saw
below the gullets and parallel to a normal tooth line. The heal
of the saw is high and the rest of the tooth line is wavy. The
teeth are uneven, misshaped and have fleam.
There are a few to many wrongs here to try and correct. The loss
of plate height will throw the proportions off making it look
skinny for its 28 inch length. To improve its looks and reduce
the chance of it getting kinked, this plate needs to be
