cut out frame assemblies are made out of 1/2" high strength
aluminum. The hard work is done for you!
With minimal machining
these frames are ready to be made into nice radius tools.
Up to 2" balls can be turned (depending on model). Will
fit any 1/2" OR 3/8" tool holder (depending on model).
Model RT-2b has
a 1/2" shank and model RT-.375 has a 3/8" shank.
If you have a drill press or mill with a vise (or your lathe
with a milling vise attachment) you can make one very easily!
Our RT-2b, a "pre-broached"
model has a square hole broached to fit most 1/4" square
tool bits. Why try to file a precise square hole to fit your
1/4" square tool bits?
We also have a
small parts kit for our radius tool frames. A "convenience
kit" that many have asked us to supply containing all
the little parts (bearings, rods, set screws, etc.) needed
to finish the radius tool.
Why pay up to $150.00
to own one when you can NOW make one easily in about 1 hour?
You will need (for
model RT-.375/RT-2 will be similar):
- a piece of .250/.375
drill rod about 6" long (depends on how long you want
- a .250 dowel
pin 1.25" long
- a .250 dowel
pin 2.25" (or longer to clear height of your QC or
lantern tool holder)
BOTH DOWEL PINS CAN BE CUT FROM THE FIRST ITEM IF USING
.250 DRILL ROD AND IF BUYING EXTRA LENGTH
- (2) bronze bushings
.25 ID X .3125 OD x .5 long. THESE ARE OPTIONAL! IF NOT
USING REAM .251, TO SLIP FIT DOWEL PIN IN OUTER FRAME
- a length (about
1 to 2") of 1" brass/aluminum/steel round/hex
stock to fit handle or wrench to
- (1) to (4) 8-32
set screws. Exact number dependent on method of securing
dowel pins to inner frame, either press fit or secured with
set screws, one (or two) needed to secure toolbit and one
tool handle unless press fit or can use (1) SHCS instead
- (1) toolbit,
HSS either .1875 or .25 round X 1" long (or square
if you can broach)
