Greetings All, I'm in the process of restoring an old 20" saw. I have replaced the spindle bearings and took some measurements. I think I'm OK but this is my first 20" saw so I'm not certain. I would appreciate your opinion.
I measured blade run out. 1-1/2" from the edge, I got a total of .016" of run out.
I measured the blade/vise carriage alignment and found that across about 16" I am .004" out of alignment.
I know the closer the better but will I see any real gain in cut quality if I improving that .004" misalignment?
Thanks Glen

I've got an old frantom and it's dialed to .003 in 18 inches and it cuts perfect slabs. If you think about only going 9 or 10 onches into the blade on a cut that's .002 that should be darn near perfect

I looks like I jumped the gun a bit. My saw was not all the way together. After I finished assembly I checked and I was out .020" in 17". YUK. I added a .0045" strip of aluminum tape to one side of my spindle mount and WALAH!!! Less than .001" across 18". YEA! That eliminates that concern!
