For the age of the original engine you are building, I believe tallow was the lubricant used.

The tallow would be put in the top bowl on top of the lubricator. Top pet cock would be opened and the tallow would go into the intermediate bowl. Top pet cock closed and lower pet cock opened to allow tallow to enter cylinder (or steam chest).

The pic will give you some idea of what I'm on about.

Thanks for that but the ones ive seen are just round pieces on top of the steam chest

OK, Don. Here are a couple of (poor quality) pics of the sort of thing you are looking for.

Same idea as earlier, but only one pet cock.

The above pic is taken from the Stuart Models catalogue. Should give you a better idea. Included angle for the two parts is commonly 7 degs.

Can anyone tell me whether the lubricator on the steamchest is a plain pot for oil or is it more involved
Thanks Don
