Kondia FV-1 Head disassembly

[Mayhem]

OK - some progress!

1. Closer inspection of the back gears shows a little wear on the tops of the teeth of the counter shaft gear.  When I initially replaced the bearings in this, the selector shaft was bent.  I straightened it but after pulling it apart I either didn't do a good job or it has bent again (albeit ever so slightly).  Perhaps I did something stupid and not disengage it properly when shifting back to high range...  I'll straighten it again and will probably make a new guide shaft as the old on is pitted and I think it is slightly worn.  Without the cover on it allows the selector fork to canter a little.
   
   
2. I pulled the quill feed drive shaft and gear cluster and found that the shaft is very tight (to the point of locking up) in the top bush.  I actually had to use my slide hammer to separate the two and the bush is scored around the circumference at the top of the bore.  I'd not separated the two previously but will now polish the bore and the shaft as necessary to get a nice fit again.  
   
   
3. Dropsa have informed me that the D mark on all eight metered oilers indicates a flow rate of 4 drops of oil with a
   viscosity of 100 CST at 40°C.  Interesting, as the Bridgeport mills spec different flow rates for the nuts and slideways.  Given that one is still blocked solid and the others demonstrate variable rates of flow, I am going to replace them all and be done with it.  At less than $15 each, I look at it as cheap insurance.
   
   

I'm on the other side of the country over the weekend and Monday, so I hope to get some time before next weekend to make some further progress.
