It appears to have been made from a casting, either Bronze or GunMetal. Can anyone elighten me as to its use, it may not even be associated with the Quorn. thanks Graeme

My guess is that if it is 1.25" (the pillar that holds the motor and grinder spindle), It (might) fit under the power head, the long screw would fit in the spiral groove, the small screwto lock on the outer dia of the pillar. the longer bolt would be on the bottom side. Don't really know, I'v only got page three of the 1975 drawings (of three pages), I had a look but the nut arraingment is not on that page. Ian S C Having now looked at Chris's indicated site, I tend to agree with the between center boring bar idea. Edited By Ian S C on 24/10/2011 15:24:24
