Adjusting the blade tilt on a Delta Unisaw (circa 2000) and so adjusted the stop for 90 deg. Eventually took the stop bolt out altogether and the tilt mechanism stops BEFORE it gets to a full 90 deg. Any ideas on other adjustments as I figured it would go past 90 w/o the stop installed.

If your saw is a new to you acquisition, it’s possible the original owner did some type of repair on the screw that causes it to tilt, and didn’t register it properly. If you’ve had from new, then use the manual to find the fix…............ Jerry (in Tucson)

So, the finger that holds the stop bolt hits the trunnion before 90 correct?

I don’t believe the finger hits, with the bolt removed it stops and there’s a gap between the finger and the stop – wondering if theres a build up of sawdust on top of the trunnion somewhere

Could be any of a couple different things… but usually resolves down to sawdust/crud mucking up things, or the pointer bracket getting caught up the cabinet seam or trunnion.

These threads over at OWWM may be useful:
UniSaw cannot get it to 90 Degrees
Uni blade won't zero
My Unisaw Won't Go Back To 90

More than likely it’ll be something trivial.

Did a little more investigating today! This is weird… when I intentionally tilt the blade to the right just a few degrees off what I believe to be true 90 according to my machinist square, the thing cuts dead on 90! Am I missing something with table saw set up? Or is this thing just possessed? OMG

Why do you ‘believe’ this is off 90? Is it because your saw says it’s 90, or are you eyeballing it? I use a digital gauge as my saw label is off a little big.

Yes to both. All tools are a little possessed, and the larger and more expensive, the more it appears. Witness the countless number of videos and articles to show how to coerce a bandsaw into acceptable working setup.

When I set the blade to 90 with a machinist square, it cuts a slight bevel. When I set it intentionally to a slight right tilt, it cuts square. Im good with that if that’s life, but shouldn’t it cut 90 when I set it to 90?

The first thing I would do is check if the table was level.

Deflection of a blade too thin might be a possibility too.

Make sure you are measuring 90 on the same side your saw is cutting your test piece. Left vs. right side cuts can have a different angle if the table has a warp centered on the blade cutout. That aside, make your final test piece cut such that you are only doing a skim cut (< 1/16”). This helps take any blade deflection out of the test.
