Still waiting on my mini end mills to come, so that I can fix my Index Stop Pin (702). They should be here tomorrow, but I have a 12 hour shift........
Progress, I looked into the Spindle Stop (706 & 707). I noticed a detent in the 706 portion but no springs or brass on any of this. So I made springs & a brass 'bullet'. Having 'clocked' the spur gear to get the detent to function properly, I find the handle is pointing the wrong way. Gonna take heat to get the screw loose so that it can be turned around.
Moving forward, the Worm Shaft Pinion Knob & Nut (717 & 716) apparently came with the nut locked down by a small dowel into the main body & the knob had 4 set screws holding it tight to the nut. Somebody wanted the Index permanently engaged.
Same pics, The forward Spiral Gear Guard (no number) is Brass & is cleaning up nicely!
Now the other WHY? I have for now is the Worm Shaft Adjusting Screw (703). It will be interesting to see why a bolt was added to it.
