set consists of five fixed blocks (5°, 10°,
20°, 30°, and 45°) precision ground from ¼"
hardened tool steel. These are made in my own shop here
in Idaho. The sixth item is called the "Micrometric
Tangent Bar" (MTB) by Rover Industries, Inc. It is
adjustable from 0 to 5 degrees in one minute (1/60
degree) increments. By combining my angle blocks with
the MTB, virtually any angle can be set with astounding
speed and accuracy.
complete set includes a custom fitted case machined from
solid high density polyethylene. This is no cheap plastic
case. It protects the angle blocks far better than the
typical injection molded or wooden box.
block is cut from oil hardening tool steel which is heat
treated to a hardness of 55-60 Rc. The heat treating
process creates a blue/black oxide finish on the steel. This
is retained to help prevent rust and corrosion. The gaging edges are then precision ground to amazing
tolerances. All angle blocks are guaranteed accurate to
within 0.0001" per inch. Most come out with less
than 0.0001" total error! I use a
Starrett Webber AG16.LM angle set (considered by many to be the finest,
most accurate commercially available) and a
Southern Gage Co. Universal Dia-Lectron Amplifier model 90025 with a Brown & Sharpe
599-988 10p angle gage head to ensure that
every angle block is accurate.
angle blocks (right) are very different from the standard
low cost import angle blocks (left). First, you'll notice
that they are quite a bit larger. The gaging edges on our
45 degree angle block are aprox. 4" x 4" x
6". Typically, the 45 degree block on an import set
measures aprox. 2.5 x 2.5 x 3.5. Second, our blocks are
deep hardened from tool steel. Many import sets are case
hardened from low carbon steel. Finally, my angle blocks
are guaranteed to be accurate. Measurements of two
different import sets revealed considerable discrepancies
from their stated specifications.
the Complete Angle Set, the Micro-Tangent Bar is also available
separately. It adjusts from 0 to 5 degrees in one minute (1/60 degree)
These angle wedges facilitate setting the precise
angles needed for cutting the pieces of segmented turnings. They are almost 10 inches long and designed to be
used with the 8.5" Precision Square. Made from hardened tool steel with a natural oxide finish. Same accuracy
as the EJB angle blocks.
Import Regrind Angle Block Set
I have been looking a long time for a good low
cost angle set alternative for my customers. Unfortunately, the
popular import sets generally don't live up to their own specifications.
I decided that I could create such a set if I were willing to invest
some of my own time and expertise. This is your common every-day
12 piece set (1/4, 1/2,
1, 2, 3, 4, 5, 10, 15, 20, 25, and 30 degrees)
of 3" hardened steel angle blocks in a foam lined wooden case.
There's just one major difference: I have inspected every single block
for accuracy. I regrind any blocks which do not pass
specifications (0.0001" per inch). It happens a lot more than you
would think, some blocks being off by several thousandths! With
the reduced cost in materials, labor, and energy, I can offer this set
at a substantial savings over my regular 4" angle block set and still
sleep soundly at night!
Each block is marked with my initials and the
word "Regrind" to indicate that I have certified its accuracy (and to
make sure it isn't confused with any other low cost angle blocks).
If you can't afford my regular 4" angle blocks then this is a great
alternative that you can trust! Sorry, these will be sold only in
you have a radial arm saw, then this accessory is a must!
RS-Aligner is made from 3/4" thick blue anodized
6061-T6 aluminum tooling plate. It provides the
references needed to align your radial arm saw very
quickly and very accurately. Included is a bracket that
allows you to mount a dial indicator on the saw arbor.
Full details on this accessory can be found on the RS-Aligner home
page. Obtain accuracy in your radial
arm saw that you never dreamed was possible. (TS-Aligner
or TS-Aligner Jr. required, not included)
Angle Gage Blocks
gage blocks are used with RS-Aligner to set precise arm
angles. RS-Aligner acts as a giant 12" sine bar. So,
the length of the gage block for any given angle is
easily calculated as 12*sin(angle). I make these gage
blocks from solid 6061 aluminum tooling plate. Each one
is precisely machined and checked to within 0.001"
in length. They are available in lengths for ¼°, ½°,
1°, 5°, 10°, 20°, 22 ½°, 30°, and 45°. Custom
lengths available upon request.
squares are a bit different from most others you'll find.
They are each made from a single piece of solid, hardened
tool steel that's at least 1/4" thick. All edges are
ground and lapped to meet accuracy Class 2 specifications
(0.0008" + 0.0001" per inch of length). They
are designed specifically for use with dial indicators.
Their thickness makes it easy to run the indicator's
stylus along their edge. They will stand up or lay flat
on the table, making them ideal for use with TS-Aligner
or TS-Aligner Jr.
Every square is checked for
accuracy using a SquareMaster VSQ-18 calibrated with a Mojave 18" Lab
Grade granite square.
