Aligning a blade on 90’s Delta Tilting Arbor Saw
http://www.vintagemachinery.org/pubs/1141/25417.pdf
I have this saw, and can’t for the life of me figure out how to align the blade. It’s off just enough to be a concern. Anyone got a similar saw who has figured out how to calibrate the alignment of the blade?

you have to unscrew the tabletop and move it into alignment. There should be bolts on each corner, underneath.
I believe that saw has the same internal mechanism as the Delta contractor's saw of the same vintage.
There should be 4 bolts that hold the trunnions to the underside of the cast iron top. Loosening these bolts allows the trunnions to move in relation to the table, which adjusts the position of the blade.
Google the Delta contractor's saw 34-444 and see if the interior images look like the insides of your saw. I'm pretty sure they will.

I have the same saw and have aligned the blade, process is as described by the other 2 replies. It's a knuckle banging job as access to the 4 bolts is not great
I think the 2 replies are slightly different! This morning, I tried unbolting the table as treylek suggested (via the bolts in the far corners underneath the table top), and wasn't having much luck getting the table top to move.
Mike's suggestion is what I'll try next, which is to adjust the bolts that hold the trunnions to the cast iron top.
Which method did you use? I'm assuming trying to unscrew the table top since that's been a knuckle banging job so far.
The trunion and all that is leading to the arbor holding the blade are attached to the underside of the table. Moving the table on the frame will do nothing about the problem at hand. Loosening and moving the bolts tied to the underside of the cast table as mentioned is how you can modify the blade angle to the table and it also has to be verified in the fore and aft direction with the blade angled at 45 degrees and using shims between the trunion and table.
