Thanks to TexasGunSmith I ended up with a MT3 test bar from India. It took so long to get here that I almost forgot I ordered it! Then I found this brown sausage wrapped parcel thingy with stickers all over it on my doorstep and I was...ahhh i did order one.
So fast forward to using it. It looks the business and fits nice in my tailsotck. I lubed it with a couple drops of spindle oil. I put an indicator on it, the non taper part is 10 inches long and about .970 dia.(caliper measure for giggles) I am thinking they precision ground it from 1.00 stock. The tapered end is actually internally threaded too which seems like an extra bonus although I didn't check the threads yet.
So no matter where I am on my 6ft bed it looks lie my TS is low toward the spindle by .008 over 10 inches. So that is wear I am assuming that needs to be addressed with shimming the TS? Actually that's not entirely right. The measured dip is .010 way out in the never use area...for me! but maybe @ Raritan or Pearl Harbor she was turning some really long material?
In the middle of the bed its about .009-.008 and then near the spindle a couple thou less give or take.
I am just taking a quick test of what I am looking at to get my TS aligned with the spindle better. I have been suspect that there was an issue due to irregularities between operations but now maybe I can dial it in a little better with this tool.
So.....
What is the best course of action from here?
