Source for Pratt Burnerd (or compatible) chuck jaws?

[m_c]

I could do with a set of outside jaws for my Lathe, which has a Pratt Burnerd 160mm chuck (this model - http://www.rotagriponline.com/index...flypage&pop=0&option=com_virtuemart&Itemid=29 )

The part number I'm looking for is 8210-17602, but the cheapest I've found so far is £140 delivered. If they were going to get lots of use, I'd pay that, but I only need them for a single job.

Does anybody know of anybody of any other sources, or what would be compatible?

@brightspark not for this lathe. It's a CNC lathe that normally only has to handle up to 20mm bar, but I'm needing to make some pulleys from some 4 1/2" bar.

@grim_d that is an option, but I'm not sure if they'd grip well enough for what I'd like to achieve.

I have however just realised I could get a standard accuracy chuck from Rotagrip for £250 + delivery, which would include both sets of jaws, and the jaws are identical to the super accuracy. How can they justify £120 for a set of jaws, when you can get a complete a chuck with both sets for less than the cost of two sets of jaws?
Plus it would give me a chuck for another project.
