Help please.

Trying to make my axle pump for a Jubliee 3 -1/2 do not have a book on how too so would appreciate any sugestions on which one to buy.

Back to the pump this is a twin piston arangment . There is a 1/8 connection hole between the two outlets but does not show if a grove or hole is made into the 5/16*40 that tread into the top of the pump block blanking off the connection hole.

Second question is that the piston cylinders are a "push" fit, how much bigger does the cylinder need to be than the hole (7/16) it's going into

Thank you

In all honesty I wouldnt make this – they simply sap too much power from the loco. Its a few years now since I built this loco but I didnt fit one. What exactly do you mean "do not have a book on how to"….I dont think there is such a book?
