Wood Insulators |
Although uncommon, there are a number of insulator styles made from wood. The best known and most desirable wood insulators were made from the dense wood lignum vitae for the San Francisco trolley system. There is an excellent book about these available "Wood Amongst the Wires - The Temporary Solution" by Fred Padgett and Walter P. Ruedrich.
Here are two cable styles from the San Francisco trolley system. Two different base styles are shown, one with an inner skirt. There is also a version that does not have a saddle groove (Not Pictured) These were made on a lathe and have standard threads. |
Here is a strain insulator made from a wooden rod with metal ends. |
