Adapting 16 inch colchester 3 jaw for my hb 575 CAZENUEVE

[stuarth44]

No chucks for the CAZENUEVE were readily available so TURNER PRECISION in Kunda Park gave me, for 300 dollars this 3000 Steel with bevel gearing , then I had to bore out the chuck back to fit my caz mounting faceplate, I used a very old fashioned calliper and cut a brass rod to fit that and crept up to the target 320mm, my Mitutoyo verniers stop at 300, but I was happy to hit the target, and pressed it home using the powerful tailstock feed, chuck weight 90kg, plus abt 25 for *caz mountings, my old 3 jaw was stuffed, back of the 1 -8 D camlock is fine grained cast iron held onto the chuck body by 6 9/16 fallen head screws
