That's looking damned fine there, Rob.  Hmmm... projectitus.... I seem to recall somebody had started a traction engine....

Cheers, Joe

I sure like your grey shop!

You weren't in the military were you Rob?  As that't the exact colour they used to paint the Landrover engines in that we used to get in the re-manufacturers.... a real pain to shot blast off!



Very tidy and well presented machines they are too   :clap:



Looking forward to seeing what you get out of them over the next few how longs   :thumbup:

I know its  :offtopic:   but I was thinking along similar lines - you weren't perchance in the "Grey Funnel Line" (RN) as that's a bit similar to "Weatherwork Grey" ....?

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.

Cheers
Richard

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  :)


Cheers Rob

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.


Spent a shift scraping the saddle to get that back into shape and fitted the tapper turning attachment
 

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  :)



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:

Nice job Rob  :D - just love those gears :clap: :clap:  :thumbup:

 :scratch: I thought you were getting closer to done now, but there's no fresh grey paint on the apron or gearbox :poke:  :lol:
Have to be careful with that blue stuff as well; seems like it contaminated the bed  ::)

I have seen this lathe for myself, not many people whould have taken on such a project. :bow: :bow: :bow: :bow:
Rest assured the gears and shafts rob has made  actually look better in real life .
It is nice that a machine destined for the scrap man will be once again working. :) :) :) :)

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:



Cut off the soft tapper ,,,,,,,,, binned the rest


Cleaned up the centre in the tange


Stuck it in the lathe and rough it down to just over 5/8

Turned the shank and a short length to bang on 5/8
 
Reduced the shank at the cutting end and set the top slide to 88 deg to give the side of the cutter some relief


Parted off

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
 


Then the cutter blank was stuck on the mill and 12 teeth mill using a 60 deg cutter ,, dovetail cutter would do



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

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


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
 

The test  :D job done


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

Rob
