having got my L5, and re-motored etc it so i can now use it I came to
the question of alignment. It is not on the usual harrison cabinet, but
rather a big box leg under the headstock, and a A leg under the
tailstock end. It was a training lathe, an early mk3 from the serial
number and looks of it (from lathes.co.uk :) speeds 22-480rpm on the
I have turned a test piece on it, but im not sure how to interpret
it... help please:
the test bar was 3/4" dot matrix printer carrage guide ( lying
chucked 2.5" in the 3 jaw, with 4" sticking out. turned a dumbell shape
as follows: a light skim to clean up, then 1/2" from the real end to
3/4" from the chuck waisted by about 50 thou. touched up the tool and
then took a 5 thou (indicated on the cross slice dial) cut fron one end
to the other, which obviously didnt cut the middle bit.
When measured with my mike the end away from the chuck is 2.5thou
smaller in diameter, in 4".
Firstly should I worry about this? ( i think i should)
secondly is my test piece 'solid' enough? I only have a 1" mike, so
cannot really go much bigger, the 'ends' are 1/2" long, is this to
lastly which way do i shim the tailstock? none of my setup books tell
you, they just say "as appropriate" :( I think its the rear leg?
