| Contd. To EH. from H.{Arthur M. Hanbury - Head Complaints} Care must be taken that some insulation be introduced so that the armouring at the ends of the wires to keep it away from the actual conductors leading into the lamp connections. I suggest a piece of ebonite tubing of some sort or ferrule to replace the armouring near the end. With reference to the leakage of the pistons, it may be that the cylinders are not in perfect condition for the new pistons, that is, the cylinders were neither ground to receive the pistons not the pistons lapped with the cylinders otherwise there is no reason for the leaky pistons, except that setting the little ends to twist the ppiston would prevent the joints in the rings being sealed by the piston resting against the cylinder walls. | ||
