can some one tell me how long a steel valve stem on the inner tube should be for a wood fellow wheel I have some but they range from 2.5 to 4.0 inches long. Some are schrader no 725
Colin, I have yet to see a steel valve stem. The Schrader stems with which I am familiar have all been nickel plated brass. All the inserts in rubber stems are also brass.
The most common length I come across are 3", give or take a bit. Some of these are too fat to go through the hole in the wooden felloe.
Hope this helps,
Allan from down under.
No such thing as a steel valve stem! They are all brass, or nickel plated brass. You want a Schrader 777 or 888, or Dill or Bridgeport equivalent. They can also say TR-16. 2 3/4- 3" is all you want. We have to consider wheel balance these days. Back when no one went over 25 mph it wasn't an issue. You don't want the fat ones they sell now days. They are made for trucks and big cars, and are vulcanized to the tube which is incorrect.
Thank You gentleman and yes they are nickel plated brass. Well of my collection I have only one that is correct so I will go on the hunt, after all the fun is in the hunt.
