Resetting the Vernier Scale
13
The Vernier scale is set at the factory. However, if you knock it out
of alignment, it can be easily reset. For the Vernier scale to read
accurately, it needs to be both accurately aligned and correctly
spaced from the degree scale on the miter gauge head. Here’s how
to do it yourself.
1) You will need a 5/32” Allen wrench and a 0.005” shim to
correctly space the Vernier scale. Standard 20 lb copy
machine paper measures close enough to 0.005” to work
as our shim. Cut a sheet of standard copy machine paper
into this shape to make the shim.
Make the shim 2 1/2” long and cut it low enough (1/4”) in
the center so it doesn’t block your view of the scale.
Remember to leave the “handles” on the ends so you can
easily remove it from the miter gauge after you have
adjusted the scale.
2) Put the pin in the 0 degree hole.
3) Loosen the allen screws holding the Vernier scale in place.
4) Insert the paper shim between the Vernier scale and the
miter gauge head.
5) Push the Vernier scale up tight to the paper shim and align
the two arrows at 0 deg. To fine-tune the setting, look
at the arrows at the far left and far right of the vernier scale.
They should be precisely aligned with the lines at 9 deg. on each
side. Checking all three settings helps eliminate parallax errors
when you are setting the scale.
6) Tighten the Allen screws. Double check that nothing
moved when you tightened the screws. Remove the
shims.
Finished!
