I am building a 5" V2 to the Michael Breeze drawings and they show one mechanical lubricator between the frames driven from the crank axle eccentric. But with three steam pipes to supply I am not sure if that is a good idea.

A single Reeves standard pump is called up, but there are no actual details of the lubricator or pipes. I assume there would be a single manifold with three supplies. If one of those pipes gets starved you would never know it and the risk of imbalance may be high. Has anyone come across this or am I worrying unnecessarily?

Maybe a three piston pump is the answer, but there is not a lot of room where the lubricator is drawn?

Any advice wold be appreciated.

Thanks

John

If you go 3 pipes from one I would make all the pipes the same length, same bends

I am building the Breeze A1 and it has the same arrangement. I have chosen to make my pipes from the splitter all the same length as near as possible. Like you I am concerned about starvation as if there is a problem its a boiler off job to get at the feeds. Of course the non return valves could also be a cause for unbalanced flow.. They too are inaccessible once the boiler is on. My choice means its try it and see and keep fingers crossed!

Why not put a twin pump lubricator supplying the outside cylinders and a single pump lubricator supplying the inside cylinder, or how about hydrostatic lubrication.

Never had much luck with my 5" gauge modified Speedy feeding both cylinders from a single lubricator. Solution was a tank divided in two with a pump in each half. I can now monitor easilly both cylinders are getting oil in roughly the same amounts. I don't see why you couldn't make a three element lubricator in a single divided box? Would give confidence and peace of mind!

Greetings John, I never had much success using 2 pumps to feed my 3 cylinder A3, so replaced them with this which is 3 Ewins type pumps in 3 separate compartments in one tank using roller clutch motion feed. been fine for 6 years now and each cylinder enjoys oil.

Regards

Brian

Thank you all for your replies. Most helpful.

I think if I can squeeze the tank in I will try what Brian has suggested. It looks a good solution. Did you make the pump unit yourself, if so are drawings available? It looks like your tank is across the frame. Where have you taken your drive from?

Hi John, drive is taken from an excentric on the RHS of the crankshaft, to an intermediate rocking lever on the front stretcher, which via another arm in the middle of the loco drives the lubricator arm, thus there is also plenty of adjustment available what with hole in three arms.

Drawing of the lubricator has been published on the is website.

Regards

Thanks again Brian. Have found drawings in archived ME articles and they can be adapted. They do not give details of spring below ball. Is there an off the shelf one that can be used?
