A simple jig to allow grinding of four facet tips on drills up to about 6mm (1/4 inch). The device is a fabricated construction and involves no castings. The design is based on a design in Model Engineer Magazine from about 1990, adapted to work with my particular grinder and to use materials...

OK, I'm sorry that I've only just thought of posting this project here - it has been under construction for some time now. The background: During his National Service (in the 1940's) my father had an "experience" with a Sten gun. The incident became part of the family folk law and in a rash...

I have seen many designs for jigs and fixtures to assist with accurate cross drilling but apart from the fact that you end up building a special tool for the task, most designs use guide bushes and so a different sized bush is required for each size hole that you need. The following method...

This is really just a mounting method, so I don't know if it actually counts as a 'tool' but here goes: Some years ago I bought a job lot of old tools and amongst them was a metric micrometer covering the range 150-175mm. This is way bigger than anything I would ever need and so I would...

Like most lathes, my lathe has a morse taper tailstock. As a result, I find I have often made tools, fittings, etc. requiring a morse taper to fit the tailstock. Whenever I get the opportunity I buy odd damaged or worn drills with the appropriate taper from surplus or secondhand tool...

My old Drummond lathe uses change wheels to cut threads but this arrangement cannot give enough reduction in feed to be used as an auto feed. There are solutions to this problem - trying to make the reduction gear train longer, making very large compound gears, making a worm reduction gear...
