Installing metal valve stems

[HalcyonDays]

To follow up on my original post. It turned out the metal valve stems I had installed were not the cause of the leaking tube. While installing the tire on the rim I inadvertently ripped the tube. The rip was not close to the valve stem but when the tire was inflated the air was coming out around the valve stem. The big lesson for me was how to install tires on rims using a plastic bag and zip ties, much easier than what I had been doing. Metal valve stems now have been installed on new tubes and tire on rims no leaks.
