This is not a finished camera mount product, but the photos can easily show you how to make a GoPro (or other camera) mount for a Model A that should easily mount and be removed quickly when necessary.
I got this flashlight mount from Mac's (other vendors sell them too). I didn't need the flashlight, but instead I decided to add a 1 1/4" piece of pvc pipe to make a cheap diy camera mount with. I can cut the pipe at the length I wish. I can leave it round or flatten the end piece as it suits me. I can also make several for different applications if I wish. For security purposes, I can pull it out and take it with me or hide it somewhere else when i am done with it, too. I decided to paint over the white pvc plastic tube.
A 1/4X20" bolt can be added to the mount or you can use the flattened area to mount the stock GoPro plastic pieces to. You would have to flatten out a longer area though to do that, I suspect. Any rate, pvc is cheap so if you make a mistake it is easy to trim down another piece and start over.
Like say, I would have shot a photo of the holder and mount on the steering wheel of my pickup, but it is taking the paint too long to dry today because of the high humidity.
The black paint was drying slowly as we have a high humidity locally today. I am not such a fan of the color of the metal mount, so I may do something about that later, but as a quick and easy diy system, this should help anyone who is just looking for a different way to mount their camera to their Model A.
If it works well when i am done, I'll post and if I run into glitches I'll also post that. I just enjoy playing about with diy ideas that strike me as dooable and cheap.
Enjoy.
