I like John's description...a futile endeavor it is for sure...but it knocked a couple of things off my list of "want to do's" I think the kids will like it at the shows too...it should be relative indestructable and can still be easily turned by hand.

That will most assuredly be a huge hit for the kids at shows, Bill. Even some of the adults too, at least the younger-at-heart individuals. Any drawings you do would sure go a long way towards the beginning of building a better mousetrap.  :noidea:

Bill,
That is such a cool little contraption!  I love it!  I think I'm going to have to build one of those someday too.
Thanks for sharing your work with us!

Just saw the video.  What a wonderfull toy Bill. :NotWorthy: :NotWorthy:

Apart from making the top cover transparent how about making the side where the balls climb up also transparent so one can see it working from the side and also see the cam.  Just a suggestion.

Thanks Vince.  I have thought about a clear back plate for greater visibility just as you mention. It would be easy enough to do since that plate is just rectangular with 8 counterbored holes for the SHCS's that mount it to the two end plates. I may give it a try yet. My only concern is how the clear acrylic or Lexan would wear with the steps riding up and down against it, but only one way to tell and that is  to try it. I suppose even if that was a problem, one could occasionally pull the back plate off and repolish the inner surface.  Acrylic will for sure buff out very nicely as I have tried that before. Thanks for an excellent suggestion!!

You don't need to enclose it. Most of the others I've seen only had one side but you don't even need that:

I was wondering the same about using a clear back as well as the probable wear on it.
How about keeping it clear from just above the ladder? Cut at an angle to follow the stairs?
That would minimize the wear and you could get a good view to the inside.

I thought it would be neat to see the ball return too. But instead of clear plastic...maybe just a slot too small for the ball to pass through but big enough to see the ball pass by?

I just saw Arbalest's post. Also a possibility.

I'm seriously thinking of this as a gift. I'd like to make it smaller though. And I would have it enclosed so the player doesn't have to worry about losing anything. I think Bill, you mentioned plans? I'll be interested.

I wonder if actual glass would be better material than perspex ?
