NOTE: Table shown installed on a Unisaw without the cast iron
wing. If your saw has a cast iron extension wing on the right
hand side, it is not necessary to remove the wing. The
extension table can extend past the rails and tube.
9. Place table assembly (L) Fig. 12, in position between the two
rails, as shown. Make sure end of table is flush against saw table
(M). Using a straight edge make sure table (L) is in the same plane
and level with saw table (M). Lightly tap up or down and adjust leg
leveling screws. When you are certain table (L) is level and in the
same plane with saw table (M) tighten bar clamp (P) to hold
everything in position. Then drill 1/4” holes through the front and
rear of the extension table using holes (Q) provided in rails as a
template. NOTE: Number of holes (Q) in the front and rear rails will
vary depending on the length of the rails you purchased.
10.After the holes have been drilled in the edge of the front and rear
extension table board, fasten both front and rear rail to table using
the 1/4-20 x 1-1/2” flat head Phillips screws, 1-1/4” O.D. flat
washers and hex nuts (R).
