Headstock alignment is a critical point in every lathe, in this video I show how I've done it for my home made benchtop precision mini lathe.
Before going through the actual installation I've performed some simulations of the whole process. The headstock is installed using leveling paste that allows only small corrections once it is set. The headstock is equipped with compressing and expanding screws to let adjustments over the vertical plane and lateral screws to let adjustments over the horizontal plane.
DISCLAIMER: In the video some items show their brand because due to limitations of my editing skills I was unable to remove them. So I clarify here that there are NO SPONSORSHIPS, I DO NOT ENDORSE NOR DISAPPROVE THOSE BRANDS THAT ARE INCIDENTALLY VISIBLE IN THE VIDEO. Products are visible in the video because they are necessary for the purpose of the work shown and because I found them fitting my personal purposes, not because sponsorship or paid placement. In future videos I will try to overlay a message that clarify this point when brands appear too prominently.
Video is composed by the following sections:
0:00 Intro; 1:00 simulations; 1:42 the problem of test bar deflection; 3:40 ball-tip dial indicator may lead to erroneous readings; 4:54 counterweighting; 6:20 preparing leveling paste; 7:28 headstock installation; 8:02 alignment operations; 12:30 double check with a square and final considerations.
