Repairing a Cub Lathe
Rob.Wilson:
Hi ALL :nrocks:
I was given an old Churhill Redman Cub lathe a few years back ,i started fixing it up, but :proj: lead me a stray ,and its been sitting there for the past year or so.
And the fact that i did not have a power supply to run the lathe was always in the back of my mined ,so there was no real hurry , Well until now ,as luck would have it a member of Madmodder had a phase conveter for sale , so after a quick trip,its now in my shop :D cheers Rob .
The lathe ,I had to completly strip the head stock to repair the feed mechanisum,
The lathe came with 4 jaw (needs new jaws ) 3 jaw, 12"face plate ,catch plate and a TTA (some parts missing) , all the change wheels are there for metric and imperial
I will have to do lots of head scratching to remember were all the bits go :doh:
The cross slide and apron gearing are just a tad shagged , The cross slde lead screw was completly worn out and the gear had bent teeth.
Now for the head slapping moment, in my haste ,i set about making a new leadscrew , mesured up the thread ,turnned down the en24 bar to size , cut the correct pitch, :doh:
I cut a R/H thread , it should have been L/H :doh: what a waits of 3 hours , it now sits at the back of my lathe to remined me to pay attention :D
The old screw and the F*&d up screw
Take two, still requires the wood ruff key and the gear cut
So i am now going to put all other projects on hold and get cracking on with getting the lathe up and running.
Cheers Rob

Looks like you have a nice project going there to restore the lathe and looks like you have made a good start. Too bad about the lead screw but I think most of us have had something like that happen a few times in our past. I'll be watching as you get the rest of it into top shape. :ddb: :ddb:
Cheers :beer:

Hi Rob.
Nice job on the lead screw.
Your little mishap with the orientation of the screw reminds me of a blunder I made a few years ago. I am a pipe fitter /welder and I was working for this contractor for a chemical company, they had built this 400,000 sqft building and the heating coils were hung in the roof. The steam supply was in the air hanging 5ft lower that the coils and it was my job to pipe from the main supply to the coils, everything was generic so I made an isometric of every coil which took me about a day to complete.
In the fab shop I started to cut, mark and prep all my runs of pipe, that was about 2 days work, anyways everything cut and ready I started to fit my fittings and weld them up, I did this to everything, while planning certain ways I was going to field fit my piping I was building in my fits. Total time for everything was about 7 full work days.
I go to fit my first coil and I found it to be so so to high and so so too wide, scratching my head I went back to my prints then back to the coil, then I dawned on me I did not take off my end-to-center measurements of my fittings, I have been pipefitting for 20 years and this is one stupid thing you do while you are a rookie.
Feeling an ass I told the foreman in turn he told the boss, he came down to me and I thought he was going to kick me straight in the N*ts, but!!!!!!!!!!!! Just as he was reaming me a new one his son came flying round and a large piece of construction equipment and smashed into the new roller shutter doors they just installed that morning.
So! I kept my job and he lost a bundle!…….. Good luck with the rebuild. Anthony. :ddb:

Anthony,
Couldn't you have turned that lead screw around and used it that way? :lol: (sorry just can't resist moments like this)
I've done similar, not once but twice. Kind of like cutting a piece off and finding it's to short no matter how many times you cut it.
