Shopsmith TS-III ULTRA owner manual System Description, Positioning Control

SYSTEM DESCRIPTION

1Positioning Control

The INCRA TS-III Ultra obtains its great accuracy and repeatability from the precision cast saw- toothed racks which position the fence in exact increments of 1/32”.

2Rip Fence

The 36” long heavy-duty rip fence is precision machined for perfect flatness along its length. T-slots along the front face permit easy addition of user made wooden subfences using standard ¼-20 hex bolts and hex nuts.

3Fence Mounting Bracket

This bracket provides a quick and easy means to attach the rip fence.

4Rip Fence Glides

These heavy duty glides support the rip fence slightly above the worktable surface providing an effortless motion from one fence position to the next. The glides can be configured for either the Shopsmith model 510 or 520 rails.

5Floating Table Tab

Moves floating table with rip fence to provide extra support for the fence and large work pieces.

6Carriage

The reinforced square tube design of the carriage provides the ultimate in strength and support for your fence. The carriage rides on self-lubricating UHMW guide bearing surfaces in the base to provide a velvet smooth glide to your next fence setting.

7Primary Sliding Scale

After setting up your INCRA TS-III Ultra and “zeroing” the fence to the blade, slide this scale to read 0” under the hairline cursor. The precision etched stainless steel scale is held on a magnetic track. Use this scale as the primary source for readout of fence to blade distance.

8Auxiliary Scale Slots

Four auxiliary scale slots are provided to allow additional setups and cutting operations to take place without altering the primary scale position.

Simply slide the supplied 1/32” “floating” scale into position as needed for reference. These extra slots are great for advanced joinery applications requiring the use of the INCRA templates. You can even leave your most frequently used joinery templates from the optional INCRA Master Reference Guide & Template Library permanently installed.

9Ultra Base

The Ultra base provides both tracking and support for the carriage and is the control center for most of the INCRA TS-III Ultraʼs features.

10Base Support Panel

Once attached to your Shopsmith floating table, this panel makes it easy to add or remove the Ultra Base from your Shopsmith workstation. The T-slot design makes the final calibration alignment between the rip fence and blade a snap.

11Hairline Cursor

The large hairline cursor provides a clear visual reference of the fence location and spans all five scale positions.

12Carriage Clamp

By pushing the carriage clamp down into the “unlocked” position, the carriage is free to glide to the next setting. Pull the clamp handle up into the “locked” position and the carriage is locked solidly in place, ready for your next cut.

13Micro Adjust Lever

After pushing the carriage clamp down into the “unlocked” position, push the micro adjust lever down to place the Ultra Base into the “micro adjust mode”. After micro adjusting your fence position, simply reset the micro adjust lever and then pull the carriage clamp up into the “locked” position before making your next cut.

14Micro Adjust Knob

When in the “micro adjust mode”, use this knob to fine-tune the position of the fence in one thousandth of an inch increments. A hairline cursor and easy-to-read scale give a clear readout of your fence movement. Turning the knob clockwise moves the fence closer to the blade. Turn it counterclockwise and the fence moves away from the cutter. Each full turn of the knob moves the fence 1/32”. Micro adjust range is plus or minus 1/4”, for a full 1/2” of vernier travel.

15Micro Adjust Scale with Zeroing Feature Large easy-to-read numbers make fine-tuning your fence position a snap, and once youʼve micro adjusted and pulled the carriage clamp up into the “locked” position, you can re-zero the scale if you desire. Just rotate the scale (not the knob) gently with your fingers to return the zero on the scale to its original position under the cursor.

16Micro Adjust Cursor

Your INCRA TS-III Ultra has a micro adjustment range of plus or minus 1/4”. By sighting through the micro adjust cursor to the left end of the micro adjust knob, this feature tells you how far you have micro adjusted away from the mid-range (0”) position and which way youʼve gone. The scale is marked off in 1/32” increments.
