Speedometer gear install

I need to mount the Stewart gear on the wheel of my 1911. Has anyone made a tool to center the gear on the wheel? Would someone have one I can borrow? Thanks, Art

Art
the two tools used are found here:

the first one is the one that would be used in your case.
Perhaps you can now have someone cluge something up quickly now that you know what it looks like...

I used Kim's tool for my '25 and it's perfect. It's made by Stewart. I don't recall if it will work for your 1911 though. Your car probably uses a #22. I just lay the gear over the hub, and that pretty much centers it as I recall.

I just received Kims tool, Can some one explain how to use it? I just aint seeeing it. There are four mounting holes in the gear. Art

Art, the earlier gears do have four mounting holes. It looks like Kim's tool is for the three hole gear which came later. I have in my bits, a 4 hole gear which has never been drilled at the mounting bosses. It is drilled elsewhere with just the three holes, so it looks like Stewart were also not wasting older materials.
You may still be able to use Kim's tool. The whole idea of the tool is to fit the gear concentrically to the hub so the swivel gear meshes constantly. If you mark just one point with the tool, it will be at the correct spot. Let the gear tell you where the opposite one needs to be and let the tool tell you how far it needs to be located out from the hub. Then the other two should fall into line in the same way.
This might help.

Try the tool in the three holes in your road gear I marked below.
Be sure the three slight "marks" you make on the spokes with the tool are just
outside the wheel hub so the spacers sit vertical to the spoke right next to the hub.
I used the four hole in the 1322 gear on my car.
With the spacers, they fit just outside the wheel hub
and can be done easy enough without the tool.
In any case, lay the wheel horizontal, set the spacers on the wheel and the gear on
top of the spacers to be sure it fits before drilling.

That helps a lot. Thank you. Do you line it up with the three holes and then mark the four holes to mount it? Art

Art,
I believe you are correct. Be nice if someone would chime in.
I've mounted the road gears but didn't have the tool, however.... see if this approach aligns the road gear.
Lay the wheel horizontal with the hub cap side down and supported so it doesn't wobble.
With the inner bearing in the hub, set several spacers on a few spokes. The bearing lines the tool up on the wheel.
Run the three pins in the tool down an equal amount. I assume they are threaded and coned to line up the road gear.
Then set the tool on top of the road gear with the pins in the three tool alignment holes.
Take some wire ties, rubber bands or string, and attach the road gear to the tool at the three pins*.
Set the "tool/road gear" into the hub inner bearing and down on the rough positioned spacers.
Move the spacers in proper position under the four "bossed" mounting hole locations.
Mark the hole location on the four spokes.
*Would be easier to shift back and forth to get the spacers where you want them
with the tool "attached" to the road gear.
The four holes in my original 1913 Prudden wheels are centered in the spoke base at the hub.
I am running a script Stewart 1322 road gear. I have a block letter Stewart like yours which I believe is the earlier
but the gear and hole spacing is the same.

Please let me know if I'm all wet!!

Thanks for the advice. I just finished getting the gear installed. Now I need to find a metal driven gear for the swivel. Art

Art, sorry I didn't see this earlier, but looks like you figured it out. The metal 1911 gear is hard to find, I've seen both original steel and fiber gears used in 1911, so either would be correct.

Kim, I have the fiber gear I got from you so I will use it. Thanks for the use of your tool. Art
