Hi,
So I have a star diamond 10" and just got a good deal on another that has auto feed. The problems now... The auto feed one, does not have a separate piece for the arbor/bearing etc it slides in or is fixed into the saw base. This must have been an older model. The saw works and everything seems good BUT the saw blade has wobble, and the blade has been check its dead straight. The bearing is tight and no movement, is it slightly bent in one direction making the blade appear to have a wobble? Any way to fix or replace this? Get someone to tap out the bearing and shaft to replace or check it for trueness?
The original saw- the newer model star diamond 10" has a separate Unit for the arbor assembly that comes out. I can feel now that the bearing is moving slightly, and just recently the cutting action is hammering and vibrating. It may be from a bent blade because I cut lots of agates by hand feed.
DOES ANYONE HAVE A REPLACEMENT STAR DIAMOND ARBOR ASSEMBLY? or HAS ANYONE HAD A MACHINE SHOP PUNCH OUT THE SHAFT AND REPLACE THE BEARING? From what I've gathered it seems that the bearings are permanently? pressed into and on the shaft. Any advice on a replacement or having a machine shop fix/replace the bearing on this saw.
I can upload pics if anyone needs. If anyone has an old star diamond 10" arbor assembly or the same saw only good for parts, any help would be appreciated. This 10" is my workhorse I cut tons of nodules on it a few times a week.
What is the hammering of a blade generally mean? that its bent in two different directions or the bearing slight wobble is making it do that?

Hum not sure, but it sounds like the older machine is a direct drive from the motor is that right? pics would definitely help. If I am correct about the direct drive the best way to remove shaft bearing would probably be using a gear puller. Some of the bearings on older machines are not only pressed on but have a small grove for a snap ring that works like a bearing collar. The other option may be an extended shaft on the motor with no 2cd bearing only the motor bearing which would mean that bearing would have to be pulled again Pics would be a great help because I'm merely speculating and waving my hands. As long as the shaft is good any bearing should be replaceable.
