Although small, the lathe itself was quite evidently capable of some good work, but the irritation of disentangling the drive belt from itself, and all too frequently replacing them…
As editor, it’s one of my hopes to visit various Model Engineering societies and see their facilities for myself. Having visited a few already, it’s apparent that there is a great variation between them in facilities and the interests of members. What they all seem to have in common is a shared facility with good…
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…
