Can't say for sure due to the angle of the photo but, it looks like you've got quite a bit of stick-out on the TS RAM. Draw it in as close as you can because everything flexes under pressure -everything. The TS RAM is probably flexing just a tiny bit. If I were you, I'd call it a day and check again after a few weeks of use. Also be aware that your garage/shop floor expands and contracts with temperature and moisture variances throughout the days, weeks and seasons so, absolute perfection/stability is only something to dream about -and is not really attainable.
Also, rarely ever does the full length of a shaft require that level of precision -and when it does, a different shop tool is used to do the work. Critical shaft dimensions are usually for bearing beds etc. which are rarely ever more than 1.25" in length.
Moral of the story: Quit before you drive yourself nuts or get a backache.
