So I bought a used Jet Proshop hybrid saw about a year ago and am finding that my blade isn’t aligned with the miter slot. It’s about .035” closer to slot at back side. I get the manual out to see how to align the blade and it says to turn saw over on its top to loosen trunion bolts. Turn the saw over really? Does anyone know a better way to do this than turning the dang saw over on its top? See photos for what I’m looking at inside

Not sure, but if you do find that you can reach them all as it is, leave one of the bolts snugged up, so you are essentially pivoting on the one that is still tight. I would loosen the two at the back and one of the front bolts then just partially loosen the remaining front bolt, so you don’t have the front and back moving at the same time. Then if possible use a clamp to move the trunion incrementally in the direction you want to go. Banging with a wood block never worked to well for me.

Edit:

You will probably find that tightening the bolts affect the alignment as well, so don’t be surprised if setting it back to alignment then tightening moves it as well, you may find that you only move .015 then tightening the trunion bolts moves it toward zero.

Well after about two hours getting 5 of the six bolts loosened with the saw standing on it’s feet I think I’ve got the blade a lot more aligned than it was. Jeeze they need to make that an easier task. On that particular saw anyway.

I don’t suppose the table is attached to the case with bolts?

I recently realigned my Delta contractor for the first time in 15 or so years and thank goodness that job is done. After the adjustment I had it within .0005 of the miter slot but after using it for an hour it moved to about .002, close enough.
