Compact Dob Base
I've seen a few Al or even stainless steel Dob mounts, going the heavy route to reduce the volume problem. All a rocker box it, really, is a way to fairly rigidly support those 4 teflon pads for the tube trunnion. Just needs a way to spin well in Az, and it's solved. (Easily said, of course) I seem to remember someone just having two Y-shaped steel pieces bolt onto a thick rockerbottom with some angle brackets to help secure it to the wood. Heavy, but when unassembled took up very little room, and nearly indestructable. Don't know costs and such....I expect a plywood collapsiing rocker base would be cheaper, but probably more vulnerable to wear and tear...
