Hi All, 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 plate. 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 around...) 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 to3/4" 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 much?. 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?
