Loco Lubrication

Wow.....Many thanks for all your advice received yesterday, much appreciated.

I have some thinking to do if I want to mount (if possible) an oil tank below the footplate for a displacement lubricator given the pony truck is under there.
I saw on YouTube a drawing showing such an arrangement which is intended to give a much greater oil storage capacity but no actual video of such an arrangement.

I might take the boiler off the chassis again as its really easy to do at the moment.
Then I will be able to see what I can do within the chassis.

I was thinking of mounting a mechanical lubricator between the frames in front of the smokebox, seems to be enough room but I recall it was very difficult getting an operating rod to the lubricator arm.....will have another look shortly.

Just had a look through my model photos and found one of the cab end showing the pony truck etc......I think this negates any chance of mounting a reservoir in this area.
Included another of some boiler pipework in this area if your interested?

A bit tight but just enough room for the lubricator
Hard part running the link
Sorry for bad photo the lubricator is sat on a piece of wood on the bogie.

Jo:
I heard someone once asked why you need two hollow tube stays through a boiler:

1, For the blower.
2, For the Hydrostatic oil feed.

A follow on question if I may - how to size the lubricator or know how much oil is needed?  Is there a rule of thumb based on number of cylinders, and cylinder size, or boiler capacity or ?

Mike

Jo:
You start on a high oil feed rate and see how much oil is being sprayed up the chimney when you take the engine for a run. You then drop the flow back until you get an oily finger if you rub it round the inside of the chimney but not oil all over the driver's face.

I think I already mentioned: Too much oil is much better than too little.


Size of the oil tank depends on how much running you intend on doing between topping up the oil tank. More cylinders will use more oil.
