Metal Stem Tire Valve question
I am replacing the rubber stems/tubes on my 21" wheeled 1929 Roadster with metal valve stems/tubes. My question is: Does the metal stem require inside hardware to stabilize the stem? I used to have a '30. It had inside hardware for its metal stems. If so, any suggestions on where to locate a vendor?

That's funny, i am just about to prepare the same step... That's why i have all laid out and was able to take a photograph... see the photo. As i see it, and i am sure somebody will chime in to correct me if necessary, you need the angled piece of metal on the inside, straightening the valve. This is fixed with one off nut, this will be inside the tie. Outside, the valve is 'fixed' to the rim with another nut. |

Thanks! This confirms my suspicion. Now, to locate a vendor!

Re: Metal Stem Tire Valve question
There is no inside hardware required if you are referring to the inside of the inner tube. The only thing that goes inside is the round part of the valve stem about the size of a nickel. The nut above the odd shaped washer is firmly tightened to secure the valve stem to the inner tube. TominCologne's picture is correct.

In TomInCologne's picture above, you would not use the second bridge nut he has installed on the stem. You can see several sets of original stems on my current ad in the Model A ad section. |

Re: Metal Stem Tire Valve question
To put those metal stems in there don't you need; 1) all those pieces, 2) still need rim liners, 3) you cut a hole in a brand new tube to install those with glue. ???
Are tubes that great these days to start working on them? |

Re: Metal Stem Tire Valve question
The narrow rim liners are good whether using metal stems or not. If installing metal stems, you will carefully cut off the rubber stems, smooth out the surface around the hole, and install the metal stem, followed by the bridge washer and nut. Make sure to tighten the nut as tight as you can. I do not use glue.

Re: Metal Stem Tire Valve question
Just to clarify, I believe Mr. Karr in post 6 is referring to vulcanized metal stems already installed in vendors' tubes, not vulcanized rubber stems with dust covers ?

Re: Metal Stem Tire Valve question
coming back to this, if i may...
i was at my tireman this morning and this is what i found: - i had the thin rimliners available but we did not put them into the rims because they were all (except one) very smooth on the inside - one inside was corroded, that's being cleaned and coated with anti-corrosion and will spend the rest of its life as a spare wheel - the hole in the rim is quite a lot bigger than the outside of the metal valve. is one of those rim washers/dust covers A-1500C (Snyders number) supposed to go in there? Thanks in advance... |
