Hello,
I just found two rear wheels wood ..... The first is a Kelsey with rounded edges ....... The second gift I do not know the brand of sharp edges.
When I look at it (the second) I see that the offset to the outside of the rim is much more important than the Kelsey.
Is this normal?
What art do you think?
Olivier
The first, Kelsey.
The second with an offset outside more important.
Looks like one is dished and one not. I found this in an old thread:
"Only the earliest wood felloe wheels were dished both front and rear. Later wood felloe wheels were dished at the front only. Demountable wheels do not have dished spokes.
The spokes and felloe both are involved in providing the dishing with the spokes being slightly slanted from outside at rim to inside at hub. The spokes then have the hub area flat but the spoke lengths angle out a wee bit to meet the felloe and the felloe is either drilled at an angle or cut at an angle to accommodate the angled spoke. It is a lot of work for a very small difference but the early wheel makers thought it was absolutely necessary so they did it. The original wheels on my 1911 touring car were dished about 3/8-1/2" on the front and not dished on the back. John Regan"

Same as mentioned in this adv for Kelsey steel rim demountable.
The wooden felloe early wheels were dished.
Ken Kopsky had posted this 1910 Ford drawing of the front wheel last week, no dishing that I can see.
Olivier,
First, The way you are measuring is not accurate. The fellies are not always centered on the rim. To measure the amount of dish on the wheel you must measure across the hub from the felly. Also, you need to measure relative to the spoke at the hub (or hub flange) and not on the flanges themselves because the inner and outer flanges may be different thickness.
Second, From a basic standpoint, U.S. T wheels at least, the rounded felly is earlier. They were mostly all rounded through 1917 with crossover showing up on some cars for a couple years. Square fellies started showing up in 1918 (or so I have heard on this forum). By 1920, nearly all U.S. production nondemountable T wheels were square felly. After-market wheels, such as Firestone or Perlman, could have been either way at any time.
Third, A minor amount of dishing sometimes occurs with age or other related effects just as wheel wobble has developed in many wheels over the years. Minor dishing has little effect on safety. severe dishing is not acceptable. Concave dishing mostly looks bad, but could be dangerous if severe. Convex dishing is far more dangerous because the predominate stress on the outer wheel during a high speed turn is very likely to collapse a wheel.
Most importantly. It is good to hear from you again. How are you and your family doing?

Olivier, that first wheel photo, if it is a dished wheel, looks to be back to front, hub needs turning around.
I thought the front wheels were dished so the bottom of the tire was directly under the hub, accounting for the camber in the spindles. Isn't this correct?
Thank you for your answers.
I'll use the first wheel "Kelsey" on my 1912. The other will remain on the shelf for a future Ford T.
Wayne,
My family is better, my wife left her trolley in favor of crutches, which is easier to move around the house. It will take a few months for it to be completely cured.
Olivier
Olivier,
I am pleased to hear that the family is better. You, as well, I hope. I did recall that your wife's injuries would take awhile. It sounds as if she is doing well, however.
I am also pleased to hear that you are working on the 1912. It is a very special automobile, having survived so long in an area that has been through so much in the past hundred years. I wish you, and your family, well.
I also hope to continue hearing from you on this forum.
Drive carefully, and enjoy the holidays! W2
