Gah…

Started thinking about the book storage facility. That’s right. I’ve thought about this problem before, never got anywhere, and note I’m back to nowhere.
The issue is that I have over (and this is off the top of my head, and being very discriminatory regarding what is a paperback book) 3 cubic feet of paperback books. Done on end, and now we’re looking at (mental arithmeticcing like a madman on the bus) over 20′, and this will only get worse.
So I need a train car that…
(Time passes)
Oo! I was taking out loud while a file processed.
Train car
Goes between two sets of shelves
Each set of shelves has a rail aligned with the shelf itself
Grabber on pivot
Grabber turns to desired book
Backside of grabber braces against rail
Arm grabs book
Arm pulls book in
Debrace (totes making up word again)
Grabber pivots inline with train
Roll out

Now I see how this is going to work, this is going to need to be my first trial. This is the thing that’ll make or break the deal.

Books aren’t too delicate, so I’ll start by building a grabber
Put grabber on an arm
Put arm on a pivot
Add brace to pivot
Add train under pivot
Add track under train
Add shelves to either side of train

3′ wide is probably the max on the shelves. If I have a derailment or standard maintenance, I don’t want to have to tear apart things.
