I need to make a model of a device I am inventing. I want a nonfunctioning
model, but something that has everything the real one has, just not working,
and not down to the tiniest detail. Are there stores or sites that sell
model builders supplies? I imagine a lot of this I can cut out of regular
wood and dowels and plywood, etc, but would like a few of the pieces to look
realistic.

Thanks

Steve
