Masterchuck Features and Specification
- Four steel self centering jaws which grip both internally (expand into 70mm recess) and externally (compress onto 38mm "spigot").
- Jaw movement is 7mm change in diameter.
- Jaws provided with fixing holes for attaching steel extension jaws or home-made wooden jaws of various sizes and shapes.
- The chuck is opened and closed by rotating the outer ring with the aid of a tommy bar.
- For safety, the outer ring of the chuck is smooth with no T slots or projecting jaw sliders. The outer ring is 80mm diameter giving a very compact chuck.
- Locking ring, also 80mm diameter, is provided to lock the chuck solid and eliminate vibration in use.
- Easily changed threaded inserts enable the chuck to fit almost any lathe thread up to 1,1/2" diameter.
- Extensive 32 page instruction manual and quality tool set provided.
The Masterchuck offers a dependable versatile chuck at reasonable cost. It has just as good a grip as the more expensive scroll chucks and will do the same job. In some ways it is more versatile as it has the unique ability to freeze the jaws solid to facilitate making your own home-made wooden chuck jaws any size you like at little cost. The jaw movement is only 1/4" so you have to be careful to turn the workpiece to fit the jaws, but this process is easy with the aid of a simple gauge. The chuck is easy to use and, if you ever have to take it apart to clean it (some users never do this!) you will find that there are no fiddly springs or small parts to frustrate you and definitely no rubber bands.
