Title: Repairing a Cub Lathe
Post by: Rob.Wilson on January 17, 2010, 01:41:16 PM
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,
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010508.JPG)
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
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010510.JPG)

I will have to do lots of head scratching to remember were all the bits go  :doh:
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010511.JPG)

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.
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010514.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010515.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010516.JPG)

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
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010517.JPG)

Take two, still requires the wood ruff key and the gear cut
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010520.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010519.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010518.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010521.JPG)

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:

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.

Yep Don , it won't be the last time ,i mess up . :lol: :lol: :lol:, it happens to us all  :doh: ,  i will just have to design a project that needs a R/H lead screw  ::)
Good one Anthony  :lol: :lol: :lol:
Bernd, i think you have lost it mate  :lol: :lol: :lol: :)

I know you prob just wanted it just right and all that, but couldn't you have just used RH for LH and LH for RH  :scratch:

New leadscrew nut as well of course.

btw, how hard it it to cut acme threads  :scratch:

Hi Lads

Tonight i thought i would put the apron back together ,just to refresh the brian cell and to see how bad things are ,  and they are BAD .

here is a shot of the gearing in the apron , the large gear dose not run in the correct position on the clutch gear.when saddle travel is selected. also there is a thrust bearing missing ,were you see the three washers , thats  how it was when i stripped it . :scratch:
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010534.JPG)

The repiar job that had been done to the clutch/gear, a loverly bit of welding . so i will have to make a new cone cluch with gear , so it lines up with the other gear.
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010539.JPG)

The rest of the apron gears

And i found some damage to  the 110 tooth  change wheel

Sorry Darren i posted at the same time .

 :doh: now why did i not think of that ,as i do have to make a new nut any way  :doh:

Cutting the tread was ok , it took about 1 hour to actually cut the thread , the rest of the time was spent turnning the bar to size ,i used the Myford , it did wear down  the arms a bit  on the travelling steady

Thanks for the reply Rob..practice makes perfect and all that  :clap:

Not that you seem to need it. I was just wondering if there was a reason the thread had to be handed the right way.

I have been told acme threads are almost impossible for us to cut with our machines, though I couldn't see why?
You have of course shown us this is not so  :bow:

Very nice progress, watching this thread with great interest  :thumbup:

Hi Darren

It has just come to me , i had a brain fart , The lead screw needs to be L/H so it matches the cross slide dial 0 to 125 , if it were R/H i would have to work backwards on the dial 120 to 0 when putting a cut on .

Cutting the thread was really no trouble , and i used EN24T for the leadscrew , you just have to go slow and use a traverling steady ,as it dose require allot of force at full thread dept .

Cheers Rob

Sometimes I think the Chinese chappies put an incorrectly handed feed screw on my lathe.  With the gear box set one way the carriage feeds towards the chuck but set like that the cross slide feeds outwards. :doh:

Yep thats normal mate , my Boxford and Myford lathe ,both do that , i just have to flip the tumbler reverse lever .

Hi Lads

I thought i would make a start on the gears today , then i realised i still had no way of indexing on the myford ,as i have put the indexer on hold, and i need to cut six 1/4" keyways in the change wheel boss.
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010533.JPG)

So this morning i made this , to index of the 60T bull wheel and lock the chuck in position
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010552.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010554.JPG)
Its made to fit so it dose not need removing from the lathe ,
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010556.JPG)

Now to make a 1/4 tool holder for my slotting attachment

Well i have made the 1/4 tool holder for the slotter, and my saw has finaly finished cutting through a 6" dia cast iron bar,after 4 hours,i must get some new blades ,poor saw,,, so now i have the gear blank for the 110 t gear.

Hi Lads

Thank's very much for your very kind comments , CHEERS  :nrocks:

Nothing to show tonight , all i managed was to turn up a gear blank , anyone who may want to cut some spur gears , may be interested in a copy of a gear data chart, i keep it around the shop , its a laminated ,scan from an old mag i have . I could not upload it to Madmodders , to large , if anyone could attach it here pleased do .

A couple of questions if I may?

Did you cut the teeth to full depth in one pass or several?

Is that ordinary mild steel?

How long did it take?

Thanks

Hi and thanks Darren , any time  , The gears were cut with a comercial gear cutter and its always good practice to cut to FULL depth ,in one pass , the cutters last longer . The gear is made from  high carbon  steel ,  the same as the original gear , i did a spark test on the old gear . it took about 1 1/4 hours to cut the teeth . I also had the coolant on for the steel gear , no coolant for the cast change wheel .

Thanks  Dave ,spot on , slow feed ,low rpm's , I used 120 rpm's for the 20 DP cutter ,on  larger DP i use 80 rpms or slower . I am thinking about make an attachment for the 626 mill so i can cut some skew gears.

Rob, thanks. Mine is just a little Centec 2A. Pretty small capacity really but well made and could probably do some useful jobs, will need to have a think.  :scratch:

Hi Nick

The Centec is well made machine , do you have any cutters for it ? you never no it my come in handy one day , and if its not taking up to much room in your shop i would keep hold of it  :)

Well Lads i have made a bit more progress , the gear cutting is finished  :ddb: :ddb: :ddb: :ddb: but still lots to do .
Cutting the gear on the cross slide lead screw ,i was lucky the screw just went through the divding head spindle
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010641.JPG)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010670.JPG)
I still have the wood ruff key to cut in the lead screw .

Next and last the clutch , as you can see the repair job on the clutch was not the best , the gears don't quite mess correctly  :scratch:
Photo shows them in the positon they would be in the apron
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010646.JPG)
So i need to cut the 20T gear right up to the back of the cone , well 3mm ,1/8". from it ,and the gear needs to be longer as when i stripped it ,i found there had been a few washers added to take up the slack on the shaft .

So i decided i would have to use the shaper for the job . So i spent a few hours looking for my bracket i had made up to fit the dividing head to the shape , un-able to fined it i had to set about making up a new one  :bang: a quick bit of sawing and welding ,some 1/2" plate

i just have to finish the rest of the clutch and i can put the apron back together .

Just as an aside, when I first started cutting metal on big machines as a hobby.... I had no idea the amount of time I would spend 'getting ready' to cut metal. A bracket for the shaper to hold the RT, a mandrel to hold this casting etc etc etc an on it goes....

You did a lovely job on that table extension... nice welds...  :clap:

First rate work on that last gear, Rob.  Everything you've done here is top end. 
I always wonder what I'm going to see next when I check your latest post.  Never disappointed,
that's for sure.

Did you grind your own cutter for the gear on the shaper?

Hello Rob,
An excellent series on your work. This questrion is a bit late in the course of events, but how did you get/make the cutter for the shaper to make the small pinion on the cone clutch. I have a possible similar job and it will need a 12T, 28dp? gear near enough up to a shoulder.
 
I can't see me grinding the tooth profile by hand.

Hi Richard

sorry for the late reply ,,,,,,, i ground up the tool by hand , i dressed up the grinding wheel ,with a radus on each corner , it makes it a bit easyer to get the correct shape .


Thanks Dave and CC ,,,,,,,,,CC i hope to make some chips on it soon  :)

Hi Lads

A bit of an update on this thread  :D ,, i thought it was aboot time i did a bit more work on the old lathe  :dremel: .. spent the past few nights on her . put the head stock end all back together , and finished off the screw cutting gear box repairs.
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030018.jpg)

Spent a shift scraping the saddle to get that back into shape and fitted the tapper turning attachment
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030016.jpg)

Finished off machining up the clutch and other parts for the apron gear box and rebuilt it  :dremel:

And tonight i fitted the apron back on the lathe  :)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030021.jpg)


I still have a good bit of work left to do  :dremel:  ,, and there is still a bit of green hammershite paint to be removed from the tail stock and cross slide  :bang: :bang:

Looking mighty fine Rob, looks like its not far away from creating some swarf  :thumbup: I fancy painting my old Victoria horizontal miller, Do you use a primer at all? I have a couple of tins of Johnsons floor paint (good old grey) that I could use on it, I'm just wondering if I could get away with just sanding the machine surfaces down and then whop some paint on  :scratch:

I agree,  especially a machine tool that is lovingly restored.  I cherish every part that comes off of my lathe.  I had a much  smaller rebuild job as I  was able to  order replacement  gears for the  shattered ones and the most significant work was in  replacing the head bearings.  That  said,  it just makes the  parts that  come off the lathe now, that  much  better knowing that I bought the lathe  as scrap.

Nice work in all of the steel work shown here, very impressive!

Hi Lads

I had a bit of a slow ,chilled weekend in the shop  :med:  ,,, Knocked up a bracket for the phase converter so i could get it off the floor and up on the wall out the way . then i thought i would finish off the cross slide lead screw ,, it just needs a woodruff seat cutting easy ,,,,,,,,,,, nope did not have a cutter the correct size  ::)  ,,, so when i was at John /doubleboost shop this morning i scrounged an old 3MT drill bit to make one from  :dremel:

(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030028.jpg)

Cut off the soft tapper ,,,,,,,,, binned the rest
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030029.jpg)

Cleaned up the centre in the tange
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030031.jpg)

Stuck it in the lathe and rough it down to just over 5/8
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030032.jpg)
Turned the shank and a short length to bang on 5/8
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030034.jpg)
Reduced the shank at the cutting end and set the top slide to 88 deg to give the side of the cutter some relief
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030037.jpg)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030036.jpg)
Parted off
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030038.jpg)
Spun around and faced to a midges dick over 1/8 , then with the aid of some marker pen so i could see what was going on the front face was given some relief as before
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030039.jpg)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030040.jpg)

Then the cutter blank was stuck on the mill and 12 teeth mill using a 60 deg cutter ,, dovetail cutter would do
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030041.jpg)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030042.jpg)

Then the cutting edge was machined on ,with a side and face cutter,end mill would do  i just rolled the dividing head around a turn and started indexing from there
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030043.jpg)
Then the end off the shank was finished off ,, done correctly the cutter should be machined up a few thous over size for grinding ,, but i dont have a TCG YET
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030044.jpg)

Then the cutter was heated up very hot and quenched in oil ,, (hydraulic oil) ,,,,,,,,,,,,,, this not the correct way to harden  HSS but it dose work
After hardening and a clean up of the shank
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030045.jpg)

The test  :D job done
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030047.jpg)

There is still life left in old drill bits  :med:

Cheers lads  :thumbup:


Spot on Nick ,, it is 5/8 ACME ,,,,,,,,, I use the bench grinder and a screw cutting tool gage ,,, it is easier to start with a length of tool steel first as this makes it easier to hold when grinding .... grinding one side at a time ,, with the tool steel not in the bar .
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030081.jpg)

Then put the tool steel in the bar and lock it up , then you can use the bar as a reference .
 (http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030082.jpg)

Then grinned the other side ,, and cut off the bit you need ,,, i use the good old dremel  :dremel:
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030083.jpg)

Thought i would stick this in ,,,,,,,, just because the HSS comes straight ,,,, it dose not have to stay that way , just heat it up and bend it to suit the job in hand  :med:

Again very nicely done! How did you treat the HSS when bending? Did you bend it first, then heat treat and quench?

Yer an inspiration Rob; I'm a'luvin' this thread! :beer:

I noticed in the pic of the finished 2-piece bronze nut that there are 2 allen setscrews and 2 SHCS's.  Is this how the backlash is adjusted?  The 2 setscrews are adjusted to spread the pieces apart to take out the slack then the SHCS's are locked down to hold it?

Nice looking bit of kit there Rob, very interesting stuff with the repairs.... Things to try to remember (or at least remember where I saw them!)

You really do have too many skills... I think you need to send some more of them over the airwaves!  :dremel:






Just a bit of an odd question..... You said it just needs some paint... Why are all these machines covered in that bloody awful colour (whatever it is???)


What's the matter with something a little more, well, lively?

Turquoise!?!?  I suppose that's meant to be one of them feminine shades I hear about?   I'm thinking about using bold solid colours... you know, ones men can see!  ::)

Well i have had a very slow couple of weeks ,,,,,,,,,naff all done really  ::) ,,but i did make the splash back
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030161.jpg)
Not very interesting ,i no , just a bit of metal bending ,,,but the method of welding the parts together may be of interest to  someone .
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030151.jpg)
Plug welded ........with the MIG welder ,,,,,just like a spot weld ,,, also good for fixing thin sheet to say heavy box section
Here is how on a couple of scrap bit of sheet ,,, punch /drill hole in one part
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1030153.jpg)
position and clamp parts together,,,,,,,,, position MIG touch over hole with wire in the centre of hole

Rob.

Nice job on the splash guard.  I made one similar out of stainless steel and I was pleased with it but there was an unexpected factor with it, I found it captures light and bathes the back of my lathe making my sight a lot easier. Hope it has the same effect for you.

John, I reckon the elephants are Geordie units of time. If roasting beef, weigh it and then sit by the oven and count out aloud.

Count up to 1,200 elephants per pound weight, plus an extra 1,200, then take it out of the oven.

I'm hoping I can count on a few members to pass on some tips from time to time

Rob you makes it look so easy like "I'll just slip out the back and knock up a lead screw with a spur gear on it, just before elevensies"

I''ll have to come back and read this thread again when my project is all going Murphy's way

I know this thread is a bit old, but I came across it as I recently acquired a MK 3 CUB.  Looks pretty much the same as yours.

I had to register here to say I was blown away at your work!  I started stripping mine down and luckily, everything looks to be in fairly amazing shape.

The only 3 things that I want to replace:

  1.) The Apron's Pinion Drive gear (still in functioning shape, but since it is apart...) - the Mating gear strip on the Bed is fine
  2.) The lockout pin setup is missing that prevent you from engaging the Apron's Feeds at the same time
  3.) a few bushings

Again, amazing work here.

Also, didn't get some of the attachments like teh rests and the taper attachment, but oh well.

Hi and welcome sdezego  :wave:



Wow that lathe is along way from from the banks of the Tyne were it was made  :clap: :clap:

Looks in good shape too , i would not worry about not  having the CUB steadies  , i had a set in my hands and they are abysmal , better off making your own .



Thanks Rob

Haha, indeed it is a bit away.  Sunny Florida is a bit of a journey and I feel a bit guilty at the $450 it commanded :laugh:  Been searching for the right rig for years and Right time at the right place I guess.  Just know it is quite at home as I fancy good pint of Bodingtons, Guinness the occasional taste of Meade :D

In all seriousness though. it is a steller machine.  All gears are tip top (sans the one apron pinion gear/shaft mentioned) and the worst part is merely the fascia and the 12 coats of paint thru the years.


I realize this is 360* from what this forum is about , but here is my current project (since my Harley(s) have been done for years)  http://forums.vwvortex.com/showthread.php?2805002 (http://forums.vwvortex.com/showthread.php?2805002)

I am more of a mechanic/fabricator than a machinist, so I have no facility to cut gears and what not, but your thread is a true inspiration.  Not sure what I will do about the Apron Pinion yet, but if you are interested in fabbing up that piece, I very well may be interested.  I looked at getting a Gear and cutting down the shaft/gear to fit, but I am not sure that is the best route.

Cheers,
Shawn
