Hi Phil,
Thanks for the pictures and explanations. nicely done.
I wonder if one of those rubber strap type jar screw lid removers would have worked to remove that shell ?Best Regards:

The trouble with those rubber strap things is that they stretch and so for tight items, don't work all that well (at least the ones I've used when trying not to damage the chrome finish on tapware). I did use a Ridgid brand cloth strap wrench that worked better (less stretch) but my favourite is a Vice-grip chain wrench. Phil's solution is probably the best as the wall thickness on the lubricator may not be much and spreading the load would be critical to avoid more disappointment...
Phil, I have 5/16" BSF taps and dies in one of my sets if you need one.

I know I still have the making of the levers but I couldn't resist and made a short clip of the pump in action.
Lovely to see it run as slow as it did.

Thanks for the video clip, a fascinating piece of machinery. I don't know what it is about old stuff like that, that is so mesmerizing.

I finally found a couple of the missing pics. I located them in what is called a 'cloud'.
All I can say is it must have been a very cloudy day when I saved them as I somehow have amassed several 'clouds'.
Due to some errors (surprisingly not mine this time), I will be machining two more spools and one more lever but I suppose 'practise makes perfect'

Gee Phil - the shaft in that last picture looks a bit beat up, and those glands could do with a tidy up too... ()

Another little aside job came up during all this and that was the needle out of one of the drip feed lubricators broke off.
This one was fun fun fun

[QUOTE=Steamwhisperer;1925808] Phil IMG_9182 copy.JPG QUOTE]
Hi Phil, this might sound a DUMB question. But if a disc of say 75 mm diameter were placed in between the 2 points and then eyeballed to being level.
Would that be dead on centre? Similar to a rule being placed on a round bar for drilling in the centre of the bar.
Just asking as I'm still learning this type of work.
Thanks

Now I know I'm going to get flamed for this but seeing as sometimes there is discussion about the virtues of Loctite. I thought I would show how stuff was held together etc. before Loctite was around.
Bearings and bushes that I have to renew are machined according to the 'Limits Fits and Tolerances' table and still work well.
Flame away and I will try to come back with a suitable answer.

Hi Phil,
Thanks for the great photos. In your job you would be in all sorts of trouble if some of those shafts were locited, as you have to do maitainance every so often the old proven ways of fixing are more suitable. You can get away with a lot larger tolerances with loctite and it saves time on production jobs, time is money these days.
