Look at almost any modern hobby lathe, and you will see that it is fitted with a square block toolpost, capable of holding four tools. In practice, you can usually tell anyone who has tried to run their lathe with four tools fitted by the plasters on their hands! Dave Lammas came up with a simple and elegant solution – the three way toolpost, a design that doesn’t leave you with a tool pointing straight out at the lathe operator. Dave Lammas was a prolific writer in Model Engineer and Model Engineers’ Workshop, covering subjects ranging from quirky models to an advanced hardness tester. The three-way toolpost originally appeared in ME in 1985, and the design was so effective it became really popular and universally known as the ‘Lammas Toolpost’, and can be made in a size to suit any lathe. In 1995 a posthumous article in MEW introduced the idea to MEW readers. It’s possible to carve one out of a solid block of steel or cast iron, but three sizes of casting are available from Blackgates Engineering that make machining a relatively straightforward exercise. -Neil Wyatt Subscribers Only

Chris Gill describes two phone apps he has created to help in the home workshop. The apps are designed to run on the phone operating systems (Android, Windows) or in a standard desktop browser. The apps are Geometry, which handles several calculations in plane geometry and MetalBender, which makes calculations for using a bending brake.
This free plan designed by Neil Wyatt first appeared in MEW 239, March 2016. It has been 3D modelled in Alibre Atom3D for us by Alibre.
This article by Chris Farnell first appeared in 'Maker World' magazine. Apologies for the radical header photo! Let's hope it's lead-free solder, eh?
This horizontal milling attachment by J. Neave is designed to overcome the shortcomings of running a milling arbour between centres. The design used two castings but these could be replaced by triangular blocks of suitable material.
This design by Bill Morris is an excellent test of your skill in working to tight tolerances.
John Olsen improves the drive arrangements of this well made benchtop lathe.
Here is a very useful table of different wire gauge systems.
Featured in MEW 258 and following issues, this ingenious attachment allows both ordinary spur gears and helical gears to be made on a Myford lathe.
