Thanks Bart.
This video is of a tinkered vendstar coin slot. Not what final product will be. As you can see it does accept 50¢ and was pretty easy to configure, however, it is not perfect and wouldn't be easy to duplicate the exact requirements on so many coin slots. Instead I am having that particular part replicated with a couple adjustments so that it will turn more comfortably and protect the integrity of original coin op
Are these single quarter vending machines soon to be like the 5¢ and 10¢ machines of the past. I hope not.
