Manufacturer: Stanley
Plane Type: Block
Model No: 9 1/2
The Stanley block plane number 9 1/2 is a 6 inch long block plane made
with a grey cast iron body, a hooded lever cap, a brass (or alloy) front knob,
an adjustable mouth, a lateral blade adjuster and a brass depth adjusting
wheel nut.
The body has a black jappaned finish on the top-side, as standard for
Stanley planes. The sides and sole of the plane are machined and ground
to be flat and true. The centre of the sides also have an oval shaped
indentation either side to act as additional finger grips.
If you are looking for info / review on the new version of this plane,
see the
New Stanley 9 1/2 Plane review
which is also referred to as the Stanley 5-12-020 block plane.
The 9 1/2 plane has a 1 5/8 inch blade which sits on a 20 degree bed.
The Stanley 9 1/2 plane blade has a series of grooves on the rear side
of the blade, towards the top end which locate into the lateral blade
adjuster mechanism.
Once the blade is located correctly, the depth of cut can be set by
turning the brass depth adjuster wheel nut at the rear of the plane
(note: ensure the lever cap is removed before adjusting).
The hooded lever cap locks the blade in place by sliding the lever
sideways.
The blade can also be adjusted laterally using the lateral lever adjuster.
The lateral lever adjuster is found behind the top of the blade, just
above the brass depth adjuster wheel nut. The lateral lever pivots left
and right which in turn adjusts the blade left and right.
The plane has a brass (or alloy) front knob with a depressed surface designed as
a finger grip.
The front knob has a metal lever wrapped around it. This lever is used
to adjust the mouth thickness for fine through to coarse work. When the
lever is pivoted the front section of the sole slides towards or away
from the rear side of the mouth.
The Stanley 9 1/2 block plane is exactly the same as the Stanley 9 1/4 block plane with the exception the Stanley 9 1/2 plane has an adjustable mouth whereas the 9 1/4 plane has a fixed mouth. The 9 1/2 also has a lever for adjusting the adjustable mouth. This mouth adjusting lever is wrapped around the front knob of the 9 1/2 block plane.
The Stanley 9 1/2 block plane is exactly the same as the Stanley 15 with the exception the Stanley 15 plane is one inch longer and as a result weighs a little bit more.

"Just stumbled across your website and an absolute treasure trove of information.
I was recently given an old Stanley 110 block plane and wanted to know more about it.
Your website told me everything I needed to know.
But there is so much more to read. I forsee me spending a lot of time just reading
page after page. I can appreciate how much time this will have taken to put together.
I just wanted to let you know that your hard work is appreciated."
