Thread: Clarkson autolock chucks
08/10/2009 12:26:50
Hi Antony,
                  That's OK, my Clarkson came with the Thiel 158 mill I bought a few  years back. It was made for the Thiel tool mounting system so I understand your frustration in not being able to source a spare centre. Hopefully you will be as happy as I am.

I have a J&L self locking milling chuck and a Clarkson, both were in need of centres. J&L list a replacement for theirs should give you the page the part number is TOM 53002M. I gambled and ordered  three, the gamble paid off as they fit the Clarkson as well.
Should mention that these chucks are the size that take up to 5/8"/16mm collets.  A press was needed to remove the Clarkson centre. They only have 12 left in stock.
Thread: Nitride hardening

Hi Ian,
     Thanks for the lead will give them a try. Will have to get my head around this project again as it has been lingering for a while now being well into a Satra 0-440 which doesn't need such specialist input.

      For a few years now I have been building the Bob Roach 1/6 P&W  Wasp Junior.  The crankshaft and related parts have been made, as specified, in EN19T/SAE4140 and need to be Nitrided. There lies the problem, searching the web only seems to bring up companies who operate on a large scale.
Does anyone know of a firm which takes on small one off orders ? I'm not looking for a "back door,packet of fags"  type of deal just somewhere where it could be done properly without anything being lost.
