  • Tailstock barrel depth measurement

    Tailstock barrel depth measurement

    by

    Background   Back in 1979, when my first lathe, a Myford ML7 gave way to a Colchester Bantam, one of the advantages that rapidly became apparent was the indexable micrometer ring graduated in thous on the tailstock hand wheel. This is a feature usually found on quality toolroom lathes and meant that at least in…

    A quick change hand turning rest

    by

    Background   I have considered for some time the use of a hand-held turning tool for awkward or final finishing operations on the lathe. I was somewhat put off by the fact that I am a ‘Sinister’ and these operations are awkward left-handed. I can do nothing controlled with my right hand. I even wind…

    This article originally appeared in Model engineers’ Workshop issue 129, September 2007. For repetitive work and rough turning a workpiece mounted in the chuck, a saddle-stop fitted to the lathe can save the worry of overshooting the length of a cut and so allow for more concentration on the diameter of the work. After the…

    Background To improve work holding on my milling machine, I have purchased a Soba precision vice from the Chronos catalogue. The vice is ground all over, allowing clamping on its sides or end.

    Fitting a digital readout to a Myford series 7 lathe

    by

    Link to Allendale Background We are often asked if it is possible to fit a DRO to small lathes, and in short it is possible to retrofit a DRO system to the majority of lathes and milling machines often found within the model engineers workshop. To go about demonstrating this, we acquired a 1954 Myford…

    A profile copier for the Unimat 3

    by

    A recent project required a number of caps similar in style to hubcaps and rather than having a plain surface, they needed a bit of simple ornamentation to be added. The fancy work was not to be any particular pattern, so there was no difficulty turning one of these in the lathe.   Reproducing the…
