The whole thing was wall mounted, maybe 4' by 2' and the fall of
the beans would be interrupted by pegs and blocks (all narrow
enough so no beans could be caught on top of the obstacles).<br>
<br>
That could maybe slow down a metric coffee-can dump of screws to
something that could be processed by one of the homemade
sorters. And you could probably set up a way to bet on it as one
would with actual pachinko.<br>

expensive, the benefit is lost. The cheapest E-bay unit I saw
(without the necessary stuff to sort wood screws) is around
$200.<br>

Then, I found some youtube home-made jobs. These seem more
practical for us. Though, they are not the type to just accept
a large dump of screws from the coffee tin (do they still sell
coffee that way?).<br>

Finally, this gentleman has made a rougher-hack, but he goes
into detail about each piece and how it works. Got to the
13minute mark for the real explanation about the size sorting.
Alas, like the others, it does not accept a large dump of
screws. I wonder if there is an easy way to more gradually
feed it.<br>
