Went to make a rare arbor-tilted angle cut and wondered why the back of the blade was touching the back of the insert. Duh! Upon further checking, determined the blade (front to back) was out of parallel with the miter slots by over .100" ! A litle worse than the factory new .0044". BTW, there's no runout in the arbor.

I have no idea how long it's been like this. May have happened when I moved it to a new base a couple months back. Nothing in the Jet mat'l addresses this issue, but it looks to be simply a matter of loosening/adjusting the trunnions. I'm thinking of loosening 3 bolts and pivoting it into adjustment. Guess I'll check the other adjustments as well. Any advice?

I routinely use a thin-kerf blade and wonder if the flex in it is was enough to allow ripped stock to come out the back a little closer to the desired width than a regular blade would have. Wow, imagine how much better the joints on my last few projects could have been!
