It give the inch equivalents for the following systems: The reason wire (and sheet metal) gauges get smaller as the number increases is that the originated as the number of times a wire was pulled through a die to make it thinner (or sheets run through rollers). 18 gauge wire originally meant it had been…
The ingenious design requires rather less effort to construct than a "Jacob's" style hobber, but naturally it does occupy the lathe meaning you can't easily use it for other tasks. It is probably best to make all you blanks and shafts before you set it up to make gears. In principle, the design could be…

At the very least, those seeking to run their lathe regularly at higher speeds may wish to consider this roller-bearing conversion described by Ken Willson. You may download the article HERE This article originally appeared in the Model Engineers Workshop issue 175 April 2011.
While it only covers a selection of the many brands and price points available, hopefully, it provides some objective comparisons and some idea of the differences between cheaper and more expensive calipers. www.model-engineer.co.uk/wp-content/uploads/sites/4/documents/digital_caliper_review.pdf
Intended for use on the Unimat 3, it should not be difficult to adapt the design for use on any other small lathe. Perhaps one could even make a small vertical slide using the same design principles. Download side 1 of the plan as PDF Download side 2 of the plan as PDF
