I have one 21" rim on a 26 that has the valve stem in the wrong place. I noticed that someone had bored an extra hole in the fellow for it. Any guess what kind of rim this is, stovebolt?
Most likely Chev, but other makes may also have similar valve placements.
In Australia the nickname 'stovebolt' is used to describe the 6 cylinder Chev motor, ie 'a stovebolt 6'. From where does the term stovebolt originate?
As an aside, by the time the 6 cylinder Chev came along, the rims were more likely to be smaller than 21"
Allan from down under.
My understanding is that "stovebolt" comes from the bolts used on the engines of early Chevrolet 6 cylinder cars. They were hex head with a screwdriver slot. Apparently many home stoves were put together with the same appearing bolt heads.
Yes the last 4 cylinder Chevrolet used 21" and the new 1929 6 cylinder used 20".
If your rim is a Hayes #310, it was used on:
Chevrolet Superior 1924-1925
Overland 90,96 1925-1926
Star M,R 1924-1926
The stove bolt was a round or counter sunk headed slotted 1/4-20 screw, they come in other sizes but the 1/4-20 was the most common.
