Rocker allows adjustment of the tool bit height.
Uses a machined, 1-1/2" diameter, steel rocker.
Three rockers were cut from one turning. Milled

Rocker allows adjustment of the
tool bit height.
Uses a machined,
1-1/2" diameter,
steel rocker.
Three rockers were cut from one turning.
Milled
post using a
rotary table. Adjust
tip height to 1-1/4".
Exploded view of a rocker-style tool post made from
a standard tool post.
See
small manual rotary table.
Handle Upgrades
Taig OEM tool post with fabricated steel
bushing & ratchet-type Zinc alloy
handle.
Note
recessed area around the bolt for good
clamping forces. Steel T-nuts are better.
Tool Bit Height
Gauge
A
brass tool bit
height gauge to
quickly set the tip at
center (1-1/4").
Can be used for setting boring bar
& cutoff tool
heights, too.
Added 10-32 threaded ratchet levers to all
tool posts. Made SS spacers that sit inside
the counterbored hole.
Used a brass
washer & a length of 10-32 threaded rod.
Tool Posts
Top row: rocker & standard posts.
Bottom row: backside tool post, backside
cutoff tool & boring bar holder.
Cutoff Tool Post
Cutoff tool blade is used upside down at the
backside.
The tool works well & blade is easily re-sharpened.
Uses a standard 1/16" x 1/2" x
4" cutoff blade.
Superior to the 1/4" x 1/4"
shank
cutoff tool bit.
All-steel construction.
This cutoff tool blade holder
was also adapted for use on the
9x20 lathe.
See
T-bar Cutoff Tool.
Standard tool post modified to
hold an
8mm indicator holder rod.
Quick Change Tool Post (QCTP)
QCTP Tool Bit Holders
A threaded ratchet
lever eliminates
the need for a hex driver.
Used a
1/4-20 threaded rod & a brass
washer.
Boring Bar Holder
A simple
3/8" boring bar holder for the
lathe.
Boring Bar Sets
3/8"
shank, brazed carbide insert
& Cobalt-steel
boring bar
sets
with
a fixed-position, boring-bar
holder.
This holder uses two tie-down bolts.
Eccentric Tool
Holder
This type of boring
bar holder uses a
3/8"
precision
reamed, split brass
eccentric that allows adjustment
of both
the boring bar height &
rake
angle.
Note both the small shoulder (right side
of the brass part)
that bears against its base & the center, retaining groove.
Front view. 10-32 cap-head
bolts clamp the eccentric.
The A2ZCNC T-nut is on a 10-32 threaded rod &
tightened/loosened by a
zinc ratcheting handle.
Metric Sizes
M4-12, M4-16, M4-20, M4-32,
M5-12, M5-16, M5-20, M5-25,
M6-12, M6-16, M12-50 (2 pack)

Bottom view. The area around
the hold-down bolt
was relieved
to insure good clamping contact
for the entire
bottom surface.
This is the same as
found on the bottom of a
standard Taig
tool post.
Used 10-32
thread, die-cast zinc ratcheting
locking levers for the Taig carriage stop rods,
carriage lock & the tailstock.
Used
same style levers for the Jet lathe.
For a smoother finish, lock the
carriage
when performing facing or cutoff operations.
Contacting dissimilar metals
(steel, brass, aluminum)
allow smoother locking/unlocking action.
