From this page you can download Jörg Hugel's spreadsheet investigating different drill grinding geometries, as well as a PDF document explaining how to use the spreadsheet.
This little topslide by D. Scroggins uses a novel approach to the dovetail slides. It first appeared in MEW issue 16, April/May 1993, more details can be found in the archive copy of this issue.
You can download the source code for Silly Old Duffer's Arduino Indicator system, featured in MEW 249, here.
A. Longworth describes a method of sharpening the end faces of end mills and slot drill for those who have no access to a tool and cutter grinder. Reprinted from Model Engineers' Workshop number 14.
This page hosts two free workshop Apps available to MEW readers and accompanied by articles in MEW issue 246 the 2016 Autumn Special.
Many amateur astronomers and some model engineers will be familiar with the friction-drive Crayford focuser used on may telescopes, which is typically far superior to rack and pinion arrangements. They may not be aware that its inventor, John Wall, named it after the Crayford House Astronomical Society, of which he was a member.
In MEW 240, April 2016, Alistair Sinclair revisits an old design by D.H. Downie.
This spreadsheet allows you to easily identify a suitable number of holes and turns for dividing with any indexing head.
This is a corrected table giving correct figures for dividing with the vertex HV6 dividing head.
David Thomas was interested to see the online '3D models' for a belt drive modification to an X3 Mill. He thought that his detailed model of L.C. Mason's Minnie traction engine design might provide further interest.
In MEW 236 we featured an article by David Thomas on converting an X3 mill to belt drive. You can download the 3D PDFs here. Subscribers Only
In the past climb milling was seen as bad practice, leading to broken cutters and spoiled work, but the advent of CNC and minimal backlash machines has seen it become a preferred approached under these circumstances.
Produced in response to a reader request, E. G. Hartwell proposed this method of converting a cross vice into a vertical slide. This free plan was first given away with issue 15 of Model Engineers' Workshop, February/March 1993.
This handy accessory by A Longworth was first published in MEW 14, December/January 1995. The particularly clever aspect is a simple setting device.
It's a sad fact that sooner or later we will all have to leave our workshops behind or sell them on. Roger Backhouse's 2014 MEW article on disposing of a workshop offers some sage advice that may make the process easier for us or our families and friends.
This intriguing device by W.B. Taylor, first published in MEW 13 October/November 2013, will serve little purpose other than to promote much discussion between all those who are shown it! It does, however, provide some interesting machining operations and could be made and finished to a high standard in which case it would make a nice Christmas present as an executive toy for that friend who otherwise has everything!
Take a photograph that sums up the spirit of home-workshop engineering. The subject can be anything that reflects what you achieve in your home workshop, from a home-made machine tool to the intense concentration on the face of someone carrying out a delicate machining operation. The challenge is to take a picture that captures the spirit of home workshop engineering, rather than just documenting a tool or a process.
Another design from Mt G. Gray. Following on from his lathe-mounted bandsaw this is a neat design for a filing machine that can also used with fretsaw blades. It first appeared in issue 12 of Model Engineers' Workshop, August/September 1992 - more details can be found by looking up this issue in the online archive*.
This article was previously published in Model Engineer No. 3557, March 1977, and was drawn to our attention by the letter below submitted to MEW by Alastair Sinclair. Given the high levels of interest in screwcutting clutches for modern lathes based on the Hardinge design in recent years, we felt that this article would be particularly useful for readers. This article is copyright My Time Media and the Author.
Please be warned, this article involves scenes of severe cruelty to a small lathe, and set-ups that are decidedly risky. The author produced the subject of the article many years ago and has since learned how lucky he was to get away with it... Right-click and 'view image' to see bigger pictures and plans.
