    Dual Lathe Tool Height Setting Aid

    Another lathe tool height setting aid. Not very elegant, but simple and quick to make. The base was cut off a piece of 30mm bms round bar, drilled and tapped for M6. The two tabs are 22 mm lengths of 20 x 5mm bms flat bar, each drilled through 6mm near one end. The gauge was assembled with 6mm threaded rod, nuts and washers as per Photo 1. The assembly is adjusted until the junction of the two pieces of flat bar is exactly at the lathe center height from whatever datum you choose (mine rests on the lathe saddle).
    The bottom of the top tab is used to set the height of tools held in the front tool post (Photo 2) and the top of the bottom tab is used to set tools mounted upside down in the rear tool post (Photo 3).

    Inelegant? Not really, a better term is 'functional'.
    Especially when compared to fancy boogers sold by all the supply houses, attracting the gotta-have-it crowd as a conversation piece. This one-ups most center line gauges by representing both upper and lower planes.
    I'll re-recommend finding centerline accurately, procedure that works if decent flat surfaces occupy the carriage.
    Chuck and dial in or turn round stock of stout diameter, measure resulting size, divide that in half and record.
    With height gauge, or depth mic and 1-2-3 blocks, 4-way caliper; find height from flat datum(s).
    Subtract the half diameter from height just measured.
    Centerline found!
    Sincerely,

    Thank you for this useful tip Toolmaker 51. In the past I relied on the dimensions provided by the lathe manufacturer, but I am sure your method is going to be more accurate as my lathe is 42 years old.

    Ingenious! If it's inelegant and it works, it ain't inelegant!

    The only thing I would change is maybe use a 2" magnet for the base, but it's durn near perfect the way it sits. Kudos and attaboys!

    Thanks Fast.Eddie the magnet is a great idea. Will drill into the base from below, add magnets & see how it works.

    Love this

    This is going to be the first tool I make from HOMEMADETOOLS.NET as its simplicity makes it truly a beautiful piece of work.
    Thank you for sharing it with all of us here. It's an absolute gem of an idea.
    Cheers, Al.

    I built one just like it years ago... super-useful. Mine is set so that I can just set it on a flat part of the ways of my lathe and adjust a tool right in the QC holder. Two best features are that you can set up a new tool without interfering with anything that might already be in the lathe chuck, and you can set up upside-down cutters like my cut-off blades.
