Hi,
New to me 400l appears to have out of aligned tailstock. Tried to fix by altering gib, but seems to only move one axis. Am about to grind the piece of spacer material between the two parts of the stock, is this the correct thing to do?

Section E (or section 5, if numbered) of the Instruction manual has the procedure to re-align the tailstock.
Only do the procedure after checking that the Spindle does not allow for a taper in a cylindrical cut.
If taper exists, fix that first, or you will be doing another alignment right after.

I am having the same problem th my tailstock , I have aligned the head stock , but I am not sure what screws on the tailstock body are the push and pull bolt to adjust it .The instruction manual does not have anything on alignment only on setting the postition of quill etc... Is there a procedure on alignment like the one for the head stock ?
hy michael, i have no experience with your machine type, but i have aligned tailstock on okuma's
if you wish for a few sugestions, pls share a few photos with your tailstock, so to see if it looks familiar
some models allow the tailstock to be aligned after the spindle, while others require the spindle to be aligned after the tailstock / kindly

Manual tailstock or programmable?

hy a fully programable tailstock can do all these from code :this machine has a programmable not manual ..are they the same??
... clamping/unclamping the part
... traveling to home position ( far right )
... traveling to approach position ( pretty close to part face, thus clearance position )
a manual type requires to be moved by the operator, maybe assited by the turret
if your tailstock looks like the one from attachement, and if after removing all those blue-screws, then is possible to rotate/translate it, then i can help you to align it at least in the plane that is paralel to the guidesI am not sure what screws on the tailstock body are the push and pull bolt to adjust it
if the tailstock needs to be raised / lowered, thus if it needs alignment in a plane that is perpendicular to the guides, then it would help if you would have an excentric sleeve inside your tailstock, and that, again, i don't know, maybe dhardt can provide a few ideas about how to do that on your machine
however, in some cases, the alignment in the plane that is perpendicular to the guides is required only if the head-stock was not re-aligned properly : thus if the headstock and the tailstock do not align in the plane that is perpendicular to the tailstock guide, and if there is needed to raise the tailstock, then maybe you should lower the head-stock instead ...
you have aligned the headstock, but do you know how far you are now from the original position ? for example, if your tailstock can be aligned in the plane that is perpendicular to the guides, only for 0.6mm, and your headstock is out of that field, then you are a bit in a tiny trap
to answer all those, is needed to align the tailstock axis at least paralel to spindle axis, and i can help you with this; after that, using a coax, you could see how far are those 2 lines from being coincident / kindly
