The blade on my contractor saw is parallel to the miter slots when the blade
is at 90 degrees, but gets off when the blade is tilted. Quite a bit by the
time I tilt it to 45 degrees.
It's my understanding that this is caused by the trunnions not being in the
same vertical plane and the solution is to shim the "high" trunnion.
My question is this. Is it possible the determine the "high" trunnion by the
direction in which the blade is off? My saw (a no-name Taiwanese clone) is a
right tilt and the back of the blade is further to the right than the front
when it it tilted.
If your TS has two, parallel tie-bars that span the trunnions, I can send
you two posts I made several years ago that cover how to do the alignment
(plus extra info) that covers that problem. The Delta site also now has the
same alignment procedure on their site. Search for model 36-444 manual.
If your email address is valid, I can send the posts directly to you have
the two tie-bar style undercarriage or I can repost them if they're
I got mine fixed. I decided to shim the front trunnion down a lot (1/16") so
I'd be sure if it was moving things in the right direction. Turns out it was
exactly what I needed. A whole 1/16" of an inch! Sheesh! I've had the saw
at least 15 years. It had been a while since I tilted the blade, but it
wasn't over a few years ago. And it was OK then. I wonder what put it out
of alignment? Oh, well, the problem's fixed so I won't worry about the whys
But I, and apparently at least one other, would still like to see the article.
Possible answer, but it seems kind of old results of a google groups
search for the phrase trunnion alignment in rec woodworking, first
result, watch the wrap.
Interesting article. I had searched on "table saw alignment" so of course I
missed that one. I've got to learn to specify search terms better :-).
Perennial question, probably can google for a web site. Has to do with
those two rails that hold your motor mount not being coplanar. Get them
right with a good flat board and perform the trunnion check.

Thanks George, but neither of those websites, nor any others that Google came
up with, dealt with the problem I described. My saw passes all of their
tests just fine. They never said "Now tilt the blade and repeat test X" :-).
It's turtles, all the way down
