A while ago I picked up a nice SIP P1-2 20mm tilting rotary table. This is an opportunity to thank Chuck of this parish for sending me a copy of the manual and to show you my indexing adaption.
I had a couple of double sided index plates and a set of sector arms so while under house arrest for some thing I'm supposed to have done to Pam Demick (I swear I don't know the woman!), I thought I'd fit them to the RoTab.
There's no where to mount an adapter other than into the dial shield casting , so I made the adapter a slip fit and registered it against the fiducial quadrant - which isn't the 90 degrees that I assumed it was! hence the bronze shim/clamp (it adjusts out with a tapered grub screw from behind the plates.)
The handle was a major pain , since all I had to make it out of was some unknown stainless steel. When first assembled - it gauled and seized after a couple of turns , so i had to add a bunch of fiddle-arse bronze bearings .
