Here's a link to an article by Jose Rodriguez that may
be helpful. Also some info by Rick Kruger

Good Morning Frank,

I am turning 1/2" dia 6061 aluminum and 1/2"
12L14 stock. Using
a dial indicator on the carriage, I am seeing .010"
reading from the
chuck (standard 3 jaw) to the ts, measuring against
the rear of the
stock. On the top of the stock, I am seeing a 020"
from the chuck to
the ts, with the live center bearing on the stock,
or not. Is it
possible the hs is not correctly aligned with the
bed, and ts height?
I am a former machinist, although that was many
years ago, and am
just getting back into it as a hobby. I was thinking
that either
shimming the hs to the ts height to correct the
difference, and
perhaps some judicial filing of the hs base to
correct the
parallelism to the bed. Any tricks you could provide
would be greatly
appreciated. Best regards, Nick

It seems unlikely to me that the HS is out of

it
close enough for most work by simply turning a
point
onto a piece of stock using the compound and
bringing
the point of a dead center mounted in the TS to
meet
it (see photo).

What diameter stock are you turning and how are
you
holding it?

Good Morning All:

Having trouble setting up a Homier 7X12
lathe
recently
purchased. This lathe is turning a taper from
tailstock to headstock
no matter how much adjustment I make to correct
tailstock setover. Is
it possible that the tail and head are not set
parallel to eachother?
Has anyone else run across the same difficulty?
Any
advice on this
problem, with methods to correct it would be
greatly
appreciated, as
this little unit appears to be a good value for
the
money. Best
regards, Nick
