Carter Index Plate Kit for the Taig
The index plate has 60 1/8" diameter holes
around the rim, three countersunk holes for mounting to the pulley, and
a 1.1" center hole to clear the lathe spindle. I supply 3 #6 screws for
mounting to the pulley.
Price: $35.00 with free US First
Class Mail. (Other shipping contact me, I will ship to the

me to order.
Although I previously sold a complete kit
including the pin and block that locks the pin, I have found it
uneconomical to do so.
I am only selling the index plate itself, with mounting screws,
but without the index pin and block.
You can easily make one yourself, or come up with a spring loaded

Aluminum recycled sheet. Made on the Taig CNC Mill.
Here are the dimensions of the 60 hole index plate.
Dimensions may vary somewhat.
The center hole is now 1.1" so it fits the new spindle.
You will need to make a Centering Plug to mount
the index plate to the pulley.
Fit the centering plug to the index plate bore as the bore dimensions
may vary by +/- .005"
(both items not included with the kit)
I now provide 3,
1/8" holes spaced equally with the countersunk holes so you can use a
standard 1/8" transfer punch instead of making your own .14" one. If
you do make one, make it 1/8".
centering plug dimension should now be 1.1" rather than .75"
as I have changed the design to fit the new spindle.

- From a scrap of 1.1" or larger diameter steel, brass or
aluminum bar, turn a centering plug so that the plate can be mounted
concentric to the pulley. It should consist of two diameters:
One section should be 1.1" +/- and about 1/4"+
long. Use the plate as a gage while turning, the ID isn't always
The other section should be .624 +/-, or a slip fit on the pulley ID,
and about 1/2"+ long. This will determine how concentrically the index
plate is mounted, so take care making this piece.
- Remove pulley from lathe headstock. Use a gear puller or
arbor press, do not hammer! Email me if you are having problems. (email@example.com)
- To ease reassembly, file a small flat where the setscrew
has contacted the shaft.
- Place plug in pulley and place index plate over other end.
Using a transfer punch, mark the locations of the three screw holes
which mount the pulley to the plate. (Some users have reported that the
prefer to mark one hole, tap for that hole and mount the plate, then
mark where the other two holes go.)
- Drill and tap holes 6-32, about 3/8" long
- Screw the plate to the pulley, leaving the plug in place,
to ensure concentricity. Remove the plug. You can check for runout of
the plate at this point with a dial indicator - try and get runout to
+/- .002 or less, the less runout the better the plate will perform.
- Remount pulley, making sure setscrew goes into the flat you

The plate has three rows of holes, 1/8" diameter. I am
only offering it with a 1.1" center hole, but it can still be used on
the older lathes with no problems.

there is a lot of room on the top and sides for one.
