ROB ROY Lubricator

Which book are you using?

In mine (Rob Roy/William) it has several drawings of the lubricator o p57. The boiler fitting seem tobe weel covered too.

It has a description on page 57, but no drawing on the lubricator itself, only drawing of the box it is mounted in. I can't work out how to make it from only the description

The book I have does not have an ISBN no anywhere and it is by Model and Allied pubs. It is only for Rob Roy as well not William. I think I may look to get that book.

Just to be sure we're talking about a different set of drawings; my p5

has five drawings, the whole set rotated 90deg anticlockwise. Viewe this way, top left is a cross-section through the lubricator showin all the working parts. Next is a small cross-section of the 'hollow piston. Then an outside view of the lever, pawls and ratchet wheel Next an end view. Last, on a new line a top view with the lid removed.

Hope that helps

Hi Dave Many Years ago I built a Rob Roy and had the same problem as you. I actually found what I believe to be the Rob Roy Lubricator on P142 of"Model Steam Locomotive Construction" by Martin Evans. This also has designs for crosshead feed pumps.

Unfortunately this book is out of print and second hand copies sell for upwards of £50. However, drawings for these parts were issued separately to the locomotive drawings. LO 34 covers the lubricator and LO 36 covers the handpump. They are available from many of our suppliers but I know that Blackgates have them.

I beleive that many people replace the ratchet on the lubricator with a sort of unidirectional roller race but I don't have any details.

For what it's worth, I'm currently half way through the construction of a three-and-a-half inch gauge 'Lion' - or 'Titfield Thunderbolt' if you prefer the alternative name. I took one look at the lubricator drawing and decided that life was too short to spend it in watchmaking the ratchets and pawls and suchlike as designed by LBSC. I subsequently bought a lubricator from

It uses the unidirectional roller race clutch which Russell describes and operates a small piston which pumps an (adjustable) quantity of oil via a one-way ball valve. I believe they also sell the components for self-assembly if you prefer. I found them extremely helpful and patient when I sought advice on repackaging the components into a small tank to suit my own particular requirements.

I have no connection with

Bad form, I know, to reply to one's own post but it has been pointed out to me that the book is available much cheaper at
