Churchill CUB Lathe

[RobWilson]

Afternoon Lads 


Well I decided to fix some of the bugs on the ye oldie CUB lathe today , this is an ongoing project I do a bit here and there ,mainly when something breaks  

A bit background on the machine  ,it was made local to me by a company called Churchill's ,made quite badly as well ,well it did for its time have some innovative features .
I payed £60 for the lathe and a 6 bottles of Brown ale to have it dropped at the door . 

 

The lathe has had a hard life ,been abused and not well maintained and coupled with the poor build quality it came to me rather shagged , but cant complain for 60 quid lol 


Jobs completed to date are made a complete set of apron gears and cross slide leadscrew . 

A few before shots  , note the clutch gear is not quite right , it is in the apron though lol  and the three washers where a thrust should be 




nice weld 




new parts made.




No welding on my clutch gear 




New leadscrew and nut 






So today due to the feeds packing in I decided to make a start fixing the head stock problems , and there be a few 






The cir clip and thrust should be on this shaft 




Clutch forks need replacing /made 



And the clutch shaft end is a bit buggered 




The selector arm pivots need a re think  as the peined over shaft ends are crap , lack friction ,this causes gear selection problems . top left of photo .



had to cut ends off to remove arms . 




And there is a wee problem with the front spindle bearing ,,,,,,,,,,,,,,,,, it is showing signs of wear 






Great stuff

Nice work by the way...

That lathe surely was abused Rob. It's in capable hands now though.

Ooooohhhh... i am SO stealing that design when I have to make a new nut for my lathe! Saving that pic for later reference. THANK YOU Rob!

#3) You forgot to reinforce your gear with the proper weld fillet for added strength. I'm surprised you let a detail like that get past you Rob.

Dam do you think it will matter Willie  , I was out of High Hydrogen bubble rods 
So I just went for a one piece solid job 


I hope it holds  
The screw nut was there original design , I just made one change, to use two different size  thread sizes , reason 1 , so vibration does not affect them and reason 2 so they all use the same allen size key 
Original ,worn out nut 

My new one .

and installed 

Thanks for the comments Lads    
Cheers Rob
