Selecting Tube Size

All our Silicone Rubber Tubing is specially made for us. The sizes quoted are internal diameters (“i.d.”), and are those most commonly found in the Player Piano. To select the right size, either measure the internal diameter of the existing tubing in the middle of a piece and select the nearest size from the above, or measure the outside diameter of the fixed metal tubes and select the next size down from the above in order to get a secure fit. If you are still unsure, send us a sample of the existing tubing and we will recommend the best size. The  small “Tracker Bar” tubing is 3.4mm (1/8″), our catalogue number T1,  on the majority of Player Pianos, but some did use larger sizes – always check as above.

NEW AMPICO Transmission Frame to replace the notorious ‘Pot Metal’ original that often is distorted, which leads to seizure of the drive shafts. In many cases, this has the effect of erratic roll tempo, and – more seriously – to rolls being damaged during re-roll due to the take-up spool binding. We offer a replacement service whereby you send us the complete original frame, and we transfer the gears and drive shafts to a brand new alloy frame. Please contact us for prices and availability.
