Hey guys, so I got a few questions and hope it's ok to list them all and suss out whats going on. Some are just general questions, others will be help me

I'll start with general first I guess:

I read about the little see-saw mech that sounds like it's what helps run the balls into the plunger. Does this have to be reset at the start of every "game" I'll call. As in once all balls are plunged and you have no more, does it need to be reset. What about if you have 30 balls walk away, come back in a hour or longer? Then?

I'm putting the balls though my tumbler. I presume no problem to do this? Removes the rust and even exposes some colour on the Japanese writing. Only tumbling for around 6-8 hrs as I don't want to damage any of the intricate inscriptions.

Wall mount? Any tips. I have no back and am thinking it would be cool to wall mount it. How can I best do this without damaging the mechanics in the back.

Key!!?? Any chance of finding a key for the front at all??

Thanks guys.

I'll post Tech help in a new thread if that's ok with admin? So as not to jumble it up? Or best in one thread guys?
