Sieg C6 / SC6 Spindle Nose and Arc Euro Trade Chucks

My son wants to buy one of the self-centring 4-jaw 125mm chucks from Arc and as his new Chester uses the same mounting system (A rotating collar and 3 plug bolts) he wondered if he could use (or adapt) the Arc Backplate?

The Chester has a 50mm spindle nose and three 20mm holes on a 75mm P.C.D. Does anybody know if the C6/SC6 dimensions are the same?

Thanks

Brian

Hi Brian

I suggest you contact Arc direct, I'm sure Ketan or ian will be able to check for you.

Thanks Neil

I asked this morning but they don't have the information. Unless anybody with a C6 reads this he will have to make his own backplate.

EDIT:  Even without a positive result, getting a same-day reply from a supplier has to count as good service.

Just in case anybody finds this in a search sometime, the two are not the same as the Sieg has a larger spindle nose, but I was able to fit a Sieg SC6 backplate to a Chester DB10 Super by making a cast iron sleeve to fit inside the backplate.
