I do not make out to be an expert on cross drilling jigs but do know there have been many designs for carrying out what appears, though falsely, a simple operation. Having made and used this item in this article. Photo 1, I can confirm that it performs the task with considerable ease and to a high standard that must make it amongst the best available. The kit of parts, available from Hemingway kits (ref. 1), comprises very clear A3 drawings, all materials, hardware and a sheet giving brief instructions for manufacture. In the spirit of the "Lathe Only" series, I am proposing different methods for machining some of the parts. Even if you have a well-equipped workshop then this would still be a worthwhile project to undertake, especially in view of the ease of use of the finished article.
