I set off to find replacement jaws, and to cut a long story short…eventually sourced a new old stock set from the US that are perfect – this leaves the jaws that came with the chuck redundant.

Hi,

I purchased a “new old stock” Pratt Burnerd 200mm 3 jaw chuck a few months ago, it came with both external and internal jaws. Unfortunately when I put it on the machine I found that the internal jaws were wrong.

Just to be clear here, the internal jaws are what I consider the “normal” chuck jaws.

The jaws look right and are the right “scale” for the chuck, but somehow they are not quite right being very stiff….I think the scroll form is different, the jaws perhaps being for a slightly larger or smaller chuck.

I set off to find replacement jaws, and to cut a long story short…eventually sourced a new old stock set from the US that are perfect – this leaves the jaws that came with the chuck redundant.

The jaws are unused as far as I can tell and look a quality job…if they would suit you, then let me know and they are yours for the cost of the postage or just come to Cheshire and pick them up. They are marked R148.
