Machining and Angle Plate using a Cylindrical Square,  Harold Hall

Machining an angle plate casting without the use of another fully machined angle plate would appear a non starter. However, it can be achieved easily by using two cylindrical squares.

 

 

Angle plate machining using a cylindrical square.

The squares can be easily, and accurately, made in the workshop enabling a precision angle plate to be machined. The casting in the photograph (seen already machined) is supplied by The College Engineering Supply. Castings are though supplied, and in range of sizes, by a number of suppliers to the home workshop and the method would be equally appropriate for any of them.

 

 

 

The details for making the cylindrical square and the method

used  for machining the casting are published in my book
