Hello all,
on my Delta table saw 36-979 it offers the following advice for
aligning the miter slots to the blade.


On page 24 of the delta manual for table saw model 36-979 the
adjustment for the blade parallel to the miter slot is not working for
me.

In figure 68 it says to loosen 2 hex bolts B that hold the rear
trunnion C and pound trunnion C until the blade is centered in the
table insert. I pounded that thing for 10 minutes and it did not budge
once. The front of the blade is skewed inward slightly (1/32 to 1/16)
compared to the rear of the blade and it is nowhere near the center of
the table insert. What am I doing wrong that I cannot budge this
trunnion? Please offer help if you have had this problem before.

Thanks.


1/16" is a lot to be out.

1. With small C-clamps, Clamp each end of the carriage to the trunnion
brackets so that the carriage is locked between the brackets.
Alternativly, use along bar clamp to clamp the entire trunnion
carriage mechanism together. The idea is to not end up with the
carriage assembly loose between the trunnion brackets.

2. Loosen each hex bolt individually, remove, throw away the flat
washer and replace with new (the clearance hole in the trunnion
bracket is relatively large, the washer may be deformed and have
"memory", going back to the same place when you tighten). Snug up the
HHMS (but don't fully tighten) with the new washer in place. Do each
of the four, one at a time so you don't lose what you have.

3. Tap the carriage assembly until you achieve alignment and are in
the center of the insert. Tighten all four screws. Raise the blade
to full height and hand spin to check insert clearance, side to side
and front to back. Tilt the blade all the way over to 45 degrees
and spin it again to check insert clearance.

4. In the event that you do not have enough clearance in the trunnion
bracket holes to both align the saw and maintain proper blade
clearance, the parts are dimensionally defective. Call Delta.
