WTB driven gear(s)

WTB driven gear(s)
I just purchased a few of the old gear driven Cox car chassis and now I need at least one of the driven gears for the axles. These are the gears with a hex shaped hole in the center that connect to a hub on the inside of the right rear wheel.
Please feel free to message me or email at cal_leggett@hotmail.com.
I'm new to the forum but have been into various Cox vehicles off and on since I was a kid. Looking forward to all of the information I've yet to read on this forum!

Chicken teeth, sometimes you can find them. There looks to be one in this ebay listing: https://www.ebay.com/itm/Vintage-Cox-049-Engines-parts-Lot-car-parts/183484039315?hash=item2ab8804093:g:ve4AAOSwtFxboaEq

Re: WTB driven gear(s)
Yes, I found that auction as well. However the teeth on the gear appear to be pretty chewed up. If I can't find a Cox replacement I guess the next step will be trying to make one out of a comparable gear by cutting out the hex in the center.

If all else fails, you can break out the micrometer(or small rule), and try here.

They are easy to find. As per your descrîption, I think it's a Jerobee gear you need. Search on eBay under the name Jerobee or jomac, not Cox. You have to count the teeth as there are different types.

Re: WTB driven gear(s)
I can't find any of the Jerobee gears that fit however I think I have found one that could work with some modification:
https://www.mscdirect.com/product/details/03125424
As recommended, I got out the calipers and took some measurements to find a comparable gear. MSC wants $12.50 in shipping which is crazy, but I'm planning to contact them directly to see if they will work with me on that. I'm still looking for an original, but if I get one of these in and successfully make it work I'll post details in the model forum.

Re: WTB driven gear(s)
if its one of these models the gears come on eBay often, I've seen maybe 8 in the last year. If I see one Ill post it here. One just sold last week.

I think I have a Jerobee gear somewhere. When I get a chance I'll find it and take some measurements.

Re: WTB driven gear(s)
If you know the tooth pitch, thickness, and hex hole size I could 3D print them out of nylon. There are a couple of openscad gear generators on thingiverse that can be used to generate the gear then can import into tinkercad to make the hex hub.

Re: WTB driven gear(s)
That sounds like a great plan. I will contact you later today once I get back home with the measurements. Once we get one printed I will photo document the process of testing it on the car and create a post in the models section for others to follow. Sounds like this could be an interesting project!
