Quoted from KYBingo:On another thread, this scan was posted that showed all the component parts and their location/orientation to each other.
In this image, #49 is the bolt that mounts the switch to the bottom of the ball lifter assemble. What size is that bolt? I am missing one and can't identify the thread and length. I took the ball lifter assembly with me to two hardware stores and just returned from a trip to Fastenal. What they said was know it isn't a 4-40 or a 6-32. Looking into metrics, it isn't a standard #3 or #4.
What is the description of bolt #49. If I know this, I will be able to order an assortment of lengths. Many switches....Thanks for your assistance in this bingo matter.
By the way, what was that image from?
The image is from the 'Bally Bingo Games' or "The Green Book" as referred to by bingo guys. It was made for the Safari bingo but a lot of the parts are the same as a lot of bingos. It is the only manual that I know of that has exploded view images of bingos.
I reprinted it in 1996. I have a few copies left if you would like one. By this time it is probably on-line.
I do not know the bolt size you are looking for but I'm sure someone here will know.
