Hello All,
Seems I remember that someone here had posted their build of a odometer car that used a bicycle computer. I searched but didn’t come up with the link. I am in the process of building one and the mechanics of the car are done and tested, now to build the details. Question is when programming the computer for the proper wheel size what does a G scale wheel scale out to in inches?? I don’t use any particular scale on my RR in that I run LGB, USAT and Bachmann all together so maybe 1:24 might be a compromise.
I remember the author of the post had used 27" for his wheel size.
Maybe someone has built one of these cars or knows a formula so I can figure the proper wheel size?
Thanks
Todd
Yep, Bruce Chandler did a nice one. Took a bit of digging to find it.

Thanks Bob that is the one I was thinking of. He did do a nice job on it. Mine is very similar except instead of a covering for the picnic table area I’m constructing a small shack for the back. I see that Bruce used the setting for a 26" wheel. I still have the question of what size does a 1:20 - 1:24 wheel scale out to be in real life? I suppose there are all sizes of wheels in the proto world so maybe I will reprogram the cycle computer for a 26" wheel and see what happens.

Todd, measure the diameter of the wheel on your car in inches. Then, multiply that by the scale you want, probably 22 would be a good compromise, and that will give you a good value for the computer. I just checked an old wheel I had laying around, and the diameter was 1.21 inches, so that would scale out to 26.62 inches. Good luck!
