Graham Meek Myford Super 7 Screw Cutting Clutch

[KWILParticipant @kwil]

Andrew,

Yes the disengagement does use the Myford Tumbler lower selection holes.

This shot shows the experimental setup used to determine the angles etc. The main block is modified to allow rotation (bottom right). Many more in my Album if you want see them.

Work was done using my second S7. Both S7s have full DRO and are generally unworn status.

PM me if you need further info.

Hello Ken, many thanks for your reply, I think I have the grasped the concept, I assume that this device also eliminates anti-rotation pin. I have an old selector handle from an ML7 which I will try to incorporate into the design if it doesn't involve too much carving of the gear cover.

Best regards,

Andy.
