Hi guys,
been away from the workshop for 6 months due to a family crisis but this forum when I have had access to a computer has contributed greatly to my sanity. Thank you one and all.
Now my problem. I have a very nice spiralling dividing head (make unknown) set up on the Bridgeport and it works fine but the banjo and change gears to drive it from the lead screw are missing. I could make these but to further complicate matters the part I need to make is hexagonal, tapered with a 14 degree included angle and spiralled at 1 turn in 3 inches so I need to tilt the dividing head upwards by 7 degrees which would I presume make a gear drive off the leadscrew difficult. I am wondering if it would be possible to mount a stepper motor on the dividing head with some sort of pick up on the leadscrew and a simple??? controller to set the ratios between the screw and the dividing head.
If this is possible can someone tell me or show me how and if not possible any other ideas on how to do it?
Regards
Richard.
