Picked up the lubricator build over the last couple of days.

I wasn't too happy with the O ring on the piston, I'd seen another build where the chap had fitted a small stuffing box on the cylinder, so I re-made the cylinder to this design and used PTFE tape to stuff the gland, it seems to work Ok, finished off the other bits so this is it all together.

Fabricated an oil tank up, my first attemp from copper was a disaster I think the copper was too thick to get nice neat bends, so re-made out of some nice thin brass I had, this is the lubricator squeezed into the the tank.

I'll give it a try in a couple of days powered with a drill, I'll probably have to do a bit of :hammer: but we'll just have to see how it goes, cant connect it up to the loco as I drop one of the slip bearing into this lot :doh: and I don't fancy clearing my shop out just yet has its been simply hissing down.

There we go

Have fun

How do you expect it to work when oil is dripping from a leak at the bottom. :lol:

Thanks for taking the trouble to give some feed back John even if it was a p**** take.

Actually it started to pump no problem I was half expecting to have to fiddle with it but no it kicked in straight away, don't know how it will perform with the ratchets under power from the loco but I won't try that until I've got the water pump made, then I can strip it all down and fit the both pumps at the same time. I used some of that magic PTFE gasket sheeting stuff you gave me John to make sealing washer under the bolts on the tank they seem to be working OK left the tank full of oil this afternoon and there doesn't seem to be any leaks.

Have fun

Stew
