6. Unlock the carriage and slide the base assembly toward the end of the rails. Lock the
carriage when the 0” mark on the scale shows under the cursor. This moves the base exactly
20” to the right from its original position. (Fig. 2)

7. With the fence still gently touching both wooden blocks and everything resting naturally on the
rails, tighten the base clamping knobs and tighten a set of stop bolts against the right edges of
the base clamps. (Fig. 2)
Setting the scales
1. Find the Lexan scale that reads to 64” and cut it off at about the 53” mark, then slide the short
piece into a vacant slot on the carriage. Next, slide a 48”-32” scale and 32”-16” scale into the
same slot so the ends of the scales overlap.
2. To calibrate the new scale, lock the carriage at 30
” on the steel scale and slide the new Lexan
scale so it reads 50 ” under the cursor. Lock the carriage at 20” on the steel scale and slide
the new scale to read 40” under the cursor. Finally, lock the carriage at 6” on the steel scale
and slide the new scale to read 26” under the cursor. The difference in the readings between
the steel scale and this new scale will always be exac
tly 20”, making it easy to spot-check the
calibration of the second scale.
When the process is complete, you should be able to loosen the base clamping knobs and slide
the base assembly between the two sets of stops, enabling you to use the TS-LS in the 0
” to 32”
range with the base assembly against the “EL” stops and the 20” to 52” range with the base
against the second stops at the ends of the rails. A light coating of paste wax or spray furniture
polish (Endust or Pledge) on the rails will keep everything sliding smoothly.
