I'm ready to start building the lubricator up again so I went for a furtle and dragged my spares together.
First thing was to check that the sight tube gaskets were the right size. Notice that two of the delivery pumps are missing, these had been disused for a long time and I stripped them out to refurbish them.
The same gaskets fit the top fittings that hold the sight glasses.
The blokes who put these together in the old days at Kirkham's would know all the wrinkles and would have had specialised tools. I had to re-invent the method and play it by ear as I went on. Not as easy as it looks!
It took me over an hour to get here. All four pumps are operational again.
As I progressed more and more tackle magically appeared on the bench... But I'm making progress, all the bottom sight glass gaskets in place and the pump drive re-installed, tightened up and packed.
All the pump chamber covers are in place, all the ball valves and springs have been renewed and the delivery nozzles fitted. The screwed fitting stood on the top is one of the four stop valves, one for each pump. I have one of these missing and two lock nuts so I shall have to make them..
I could have gone on with the build but decided to finish the bottom chamber before adding any more components. I measured the stop valve up. I told you that brass finishers were a law unto themselves when it came to thread sizes. Anything that is 3/8" diameter is actually 1/8" BSP, 28tpi! So I had a putting tackle away session, found the correct tap and die and knocked off until tomorrow...
