I couldn't imagine someone cutting into the spindle with a boring tool and not realizing that they had gone too far.
After looking at a few spindles this morning it's obvious that some people don't listen to the machine while boring. 3 of 4 had been cut into. Here's a pic of the one I mentioned that has relief cut into it....now I'm wondering if this was factory or just user error. I inserted a MT3 center and it seems to seat well in the taper. The upside is: once you've had the spindle out it's only about a 30 min job to do it again. Anyone who forgot to put the spindle through the belt the first time knows this...LOL

I have decided to put new grease in this bearing cuz there's a little bit of clicking going on and then reinstall the much much much much better spindle. I have removed these back and forth in there is absolutely a gigantic difference in the run out. I want the old spindle back in no question about it.
I'm currently removing the old grease from the front bearing and I have a question. Anyone that's repack one of these bearing certainly must have dealt with the cage? They say Do not fill more than 1/3 on this particular bearing but how in the hell am I going to tell what a third is trying to squeeze grease down past the cage? Bending up all those little **** to take the top part of the cage off seems undoable as I would mess it up break at least one. How do people get around this simply guess?
This is the process of used up to this point
Hot Simple Green suspending the spindle just slightly off of the bottom of the container occasionally lifting it out and let it drip out in and out in and out in and out for an entire day I then rinsed it out with several cups of thinner there's no Clickety clicking anymore to prevent it from rusting I have it soaking in a narrow container in very thin oil non detergent. I was thinking of trying to estimate the volume of the bearing slightly warm up the bearing grease I'm going to use until it's liquidy pour it in and let it solidify some will leak out but eventually it'll stop itself up.
Please tell me if I'm doing anything wrong.
I know people think that I'm doing unnecessary things to this lathe but this is very important to me the run-out is so drastically different between these two spindles. It is absolutely 100% worth switching things out it does not take that much time is very easy process.
I am not without a lathe while doing this I have a hardinge
This whole business with accuracy is made me realize that I have to migrate to a much much better lathe I'm looking for a monarch at this point. You can find them fairly cheap in the Detroit area lots of old machine shops. Shyt you can buy a hardinge fully tool for $1,000
