Quorn Universal Tool & Cutter Grinder:  MK-I & MK-II

     The Quorn Universal Tool & Cutter Grinder is a superb addition to any work shop needing to sharpen not only lathe tools, but milling cutters, broaching tools, reamers, and even drill bits.
     Originally designed by the late Professor D. H. Chaddock in England, this extremely versatile tool handsomely repays the enjoyable hours required to build.
     There are two different versions of the Quorn: the MK-I and the MK-II. The MK-I (as seen at left) is the earlier version and is designed for motors with foot or side mounting. This unit was built by Reg Ingold and the mounting table contains a handy drawer to store the accessories and sharpening/grinding wheels.
     The MK-II is designed for flange or face mounting motors. The MK-II also has the addition of a guard over the belt. This guard and the two castings that make up the motor mount assembly are the only differences in the casting kits. The other 14 castings are identical in both casting kits.
     The book, "Quorn Universal Tool and Cutter Grinder", by Prof. D. H. Chaddock describes not only how to machine and build the Quorn but also includes the many sharpening and grinding operations it is capable of performing.
     Martin Model has accessories to make your Quorn easier to build and more versatile to use.

Universal Pillar Tool - Standard and/or Long Arm

     This tool was designed by George H. Thomas (GHT) and first described in a rather disjointed sequence of articles that appeared in the Model Engineer in the mid-1970's. All of these were later collected into a book titled "Building The Universal Pillar Tool". After being out of print for some years, it was combined with material describing GHT's Universal Dividing Head and printed as "Workshop Techniques". This is not a word-for-word reprint of the previous two books; it also contains additional useful material.
     Here are the casting sets and the book in one place.

Die  Filer

     This is an inexpensive casting set that will help you build all your other tooling and models. It is perfect for a beginner’s project. This die filer is a replica of a turn of the century (circa 1900) filing machine which originally was used for filing sheet metal dies. The die filer is used for deburring, filing at angles, general filing and cleaning. In addition to files, you can use saws and laps. Common files may be used with modifications.
     The die filer set consists of four fully annealed iron castings and drawings for machining and assembly. The finished table size is 6” by 6”; the file stroke is 3/4”; a typical file length is 3” to 6” with a maximum 3/8” diameter shank.

Strong Arm  Hand  Shaper

     This is an intermediate level project. The original purpose of a Strong Arm shaper (in the late 1800s) was to make flat surfaces. The finished tool is a bench-top hand-operated shaper which can be set up using a left or right arm. It has a 4” stroke and a 4” traverse. Use the shaper to cut metal, wood or plastic. In addition to flat surfaces, you can make profiles, grooves, vees, champers, keyways and splines. The tool can also be set up with an automatic crossfeed.
     This castings set consists of nine castings – seven fully annealed iron and two aluminum – with drawings for machining and assembly.

The following tools have been added to our growing list of casting kits. No "glossy" pictures or "grand" descriptions are available as yet - we've been too busy getting the patterns made and castings poured to get to that part. But they'll be up shortly. In the meantime you may order the castings for some of these useful additions to your shop by clicking on the "Printable ... Order Form" following each name and be assured that the castings will be of the traditional Martin Model & Pattern fine quality.
