The holes for an auxiliary fence are threaded for #12-24ġ939: Catalog artwork shows the No.
The rear fence rail (LTA-440) was through drilled and held in place with the conventional LTA-455 (Shouldered Screw).ġ942: The front fence rail (LTA-439) was through drilled and held in place with the conventional LTA-455 (Shouldered Screw). 1180 10-Inch Tilting Arbor Saw which was clinched into place from the inside of the fence rail. Instead it borrowed the TCS-282 (Special Tube Bolt) from the No. This nut, when tightened, drew a clamping arm (TCS-263 Rear Clamp Hook) up and against the rear fence rail.ĩ - Fence Rails ¶ 1939: The front fence rail (LTA-439) was not drilled through for the mounting screws. It required a one time setting (or as required depending on use) and did not need to be used every time the fence was set.Ĩ - Rear Fence Rail Locking Thumb Nut ¶ 1939: The fence was locked against the rear fence rail via the No. These knobs were painted black.ġ960: The TCS-273 Fence Adjusting Knob was eliminated with the introduction of the Jet Lock fence. This new knob design was domed on the face and had raised ribs perpendicular to the face (dome) on the outer rim. Actually the knob was redesigned at about the time of the Unisaw debut. It is not known if they manufactured the original knobs for Delta.ħ - Fence Micro-Adjustment Knob ¶ 1939: The Fence Adjusting Knob (TCS-273) was borrowed from the older style saddle type fence head used on the No. At about the same time in history this same knob was being manufactured by Davis Molding (Chicago, IL) under their Daka-Ware label and is presently still manufactured and available from Davis. In its place was a large screw that was adjusted once or as required (did not need to be activated on every fence setting).Ħ - Fence Locking Lever Knob ¶ 1939: The original Bakelite locking knob (NJ-247) had a Saturn shape (raised center rim). The change with this fence was in the deletion of the thumb screw that tightened the fence against the rear rail. 1160 10-Inch Tilting Table Saw.ġ960: The Jet Lock fence was introduced.

DC-8366?) had the edge milled square and the washers just mounted flat on the edge. This allowed for using the gage to cut wider pieces when cross cutting.Įarly (year range)saws had a counterbore seat on the face of the table edge where the fence square-to-round washers/spacers (TCS-281) mount, with the round part in the counterbore and the square part having the saddle cut that holds the fence rail (LTA-439). A washer was added to the end of the miter gage to allow it hang off the front of the table while engaging the T-slot. Tables (LTA-401) had plain U-shaped 3/8” X ¾” milled miter slots (without T-slots).ġ961: T-slots were added to the table. LTA-554 (Bearing Closure Nut) added to parts list.Ĥ - Tops and Extensions ¶ 1939: Table extension (LTA-402) were X-braced. What these marks mean, where the parts were cast, is not known.ġ942: Part No. Delta farmed out their casting work and some shops added additional identifying marks to the part number. Those parts started with LTA-800 and are not to be confused with Unisaw parts. Please note that later in time Delta briefly used the LTA parts prefix for their 10” Tilting Arbor Bench Saw (contractor’s saw).
This practice was common with all Delta machines. 1471 Guard) Additional casting prefixes will be found on saw parts that were borrowed from other machines like the die cast dome knobs (NCS-prefix). Parts for the Unisaw began with LTA-401 (Table) and ended with LTA-552 (Coil Spring For No.
