| 10) We thought we could dowel liners in position. No dowel yet conceived by RR has been satisfactory. Either liners stay put by shrink fit, or not at all. [Diagram A] Fiendishly expensive. Cannot be locked Breaks smooth surface of drum. [Diagram B - BIT OF LINER and KEY] Looks all right but it called upon to take torque promptly. Breaks liner in corner. No dowels now used. Much cheaper. 11) Crackling. We never solved this trouble. It appears to be due to axial movement of liner relative to case. The dowels type A seemed fairly good but too expensive. We noticed the surface of the liner next the alum. corroded resulting in bad temp. grade. Plating was introduced to stop this. Dowels on 'open' side of drum caused weakness & failure of case. Liner could be made in series of rings - never tried. | ||
