Hi again,
I bought a MagSwitch dial indicator, placed it on my miter gauge (which is tight) and after using a marker to mark one tooth I checked fore and aft. When the indicator is on the marked tooth at the fore edge of the saw it reads 4.25, but when I slide it back and measure from the same tooth it reads 4.5. So it’s off .25 (hundreds)?
It’s have a brand new Delta 46-460. I have read in many magazines about adjusting the trunnions. Is this easy to do or should I live with this? Is this a lot to be concerned about? I’ve never adjusted trunnions, even on my old Delta saw from 13 years ago when I had to stop woodworking.
I just had a look and both are held in place with two hex screws each on either side of the trunnion for a total of eight set screws.
Any help will be most appreciated. Thank you kindly.
Jack
PS: Hopefully I can enclose a photo.

That's funny a Delta 46-460 is a lathe, so what is the model # of your table saw
Darn it, I'm sorry, I have that lathe. I have the Delta 36-725T2 saw. Also, in all the magazine articles I read the trunnions are held on by four bolts, but I have eight set screws, two per ear. So I wonder how much wiggle room I'd have?
I'll lead off with the usual question; how does it cut? Are you seeing tooth marks along the edge when ripping a board? Are your miter gauge cuts clean and tearout free? If not, let's move ahead.
I have seen table mounted trunnions with 4, 5 and more screws. I think the article was just being generic. As to you .25 number; I would confirm that you are looking at hundredths or thousandths. I could not tell from the pic.
I try to get things on the tablesaw to within .001". If you are seeing .0025" most folks would live with that. If it is indeed .025" you could have a safety issue as your path is off by around 1/32". This could be a recipe for poor cut quality at best and kick back at worst.
Yes, tooth cuts. And yes, it’s a lot. .25. I saw a YT that shows how to adjust it by loosening the two set screws at the top of the cylindrical rod where the blade rides up and down. I’m gonna try it like the video because his was way off too and he got it to read zero on both ends.
