How to fit this collet chuck to a lathe?

• To mount this collet chuck to your lathe it is necessary to add a backplate. (This doesn't apply to the New Super Mini Lathe / WM 180 - for these, a backplate is not required).

• Machining the backplate is best undertaken on your lathe to achieve maximum accuracy.

• To do this, secure the back plate to the spindle.

• Skim across the face to ensure squareness, then machine a spigot to match the register of the collet chuck.

• It is necessary to measure the PCD of the fixing holes in order to secure the chuck to the backplate.

*Note about compatibility with Mini Lathes

This collet chuck is directly compatible with the Warco Super Mini Lathe (Item No. 4900 & 4901) - the latest version only, which is the type supplied with a 100mm 3 jaw chuck when new. For the (non-Super) Mini Lathe and previous versions of the Super Mini Lathe (those supplied with an 80mm chuck when new), a backplate is still required.
