    One of the tools/excercises in the apprentice school was a height gauge
    Machined base,spring loaded rocker arm for fine adjustment etc
    Long gone now and made obsolete by the vernier or digital height gauge
    When I fitted dro glass scales to the mill I removed a 300mm dro scale from the Z axis
    First thought was to fit it to the lathe,but I am happy with dials on the lathe
    So although I have only limited use for one and it would not cost me anything
    I decided to use it to make a digital height gauge. Here are the first steps[​IMG][​IMG][​IMG]

    Further progress.Machined some basic shape to the base,made and fitted
    support plate and a clamp type toolholder for 5mm sq HSS
    Still to make a lock for the readhead and a fine feed screw adjustment[​IMG][​IMG]

    An enjoyable exercise.Always wanted one but never thought I would have
    enough use to warrant buying one.Main thing was not allowing the digital scale
    to sit unused in the drawer,and its cost nothing to make.Made a couple of knurled adjust/locking screws and spent a pleasant hour scraping the base
    Ground up a piece of 6mm sq HSS and made fitted a fi adjusting screw
    Looks and works good,now to uses for marking out etc[​IMG] [​IMG][​IMG][​IMG][​IMG][​IMG]

    Unquestionably a very fine project which will be in constant use.

    Barry, Somewhere in my 'down load' to you, there is something similar from a cheap Chinese vernier. .



    Might I suggest that a slip of carbide either brazed or silver soldered would add the usefulness? Mine ,a classical vernier design-- has two scribers but isn't as readable because I have to use my watchmaker's glass to set it.

    Best wishes

    Norman

    Thanks Norm,i have a few verniers but gave up using them when
    digital readout became affordable.Still prefer a std mike tho if working
    in imperial.I can still see and feel a thou.Have to think about 0.02mm
    I like to use a digital mike when switching between imperial and metric
    Mainly use the digital vernier but don't trust it for close tolerances due
    to springing/out of square etc. Keep well Regards barry

    Nice piece of work Bazmark.

    The funny thing here is moments before I finished watching a series of video on youtube from mrpete. There is did a much simpler height gage. That put a smile on my face.
