Churchill CUB Lathe - RobWilson - 10-18-2015

Afternoon Lads  Big Grin


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 Slaphead 

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  Slaphead, note the clutch gear is not quite right , it is in the apron though lol  and the three washers where a thrust should be  Bash

The cir clip and thrust should be on this shaft

Clutch forks need replacing /made

And the clutch shaft end is a bit buggered 

[Image: P1100443_zpsity0vczy.jpg]


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 .

Wow - this lathe may have been owned by the people who owned my mill Slaphead

Nice work by the way...

#1)   You Suck

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.   Chin   Rotfl  Rotfl  Rotfl

I hope it holds   Rotfl
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  Cool
Original ,worn out nut
