My cyclone has a 125mm Pratt burnard 3 jaw chuck, just wondered if it is possible to mount a 160mm chuck. Obviously will need to machine a larger adapter plate.
Thought that I had read somewhere the maximum chuck size for a cyclone was 150mm but can't find any info now.

Should be possible to fit a larger chuck but the size fitted is set so that any internal tools do not hit the chuck jaws when parting off.

If you use a larger chuck you have to be sure the internal tools are clear of the jaws
