When is a hole not a hole?

[shamus]

Just finished the access hole for my Badger Creek. I made the access using 3ply and drilled and inserted 1/2" brass tube in the four corners. For the top, again 3ply with Mod-rock (Plaster babdage) topped with a light covering of plaster. Under the board are four 3/8" bolts which locate into the brass tube.

Shamus,
I was wondering, back when I first saw your new track plan, whether or not you had included access in that deep section of benchwork.
One question though...Where do you set that thing down after you've popped up through it?

Hmmm... It looks like something out of a James Bond movie or a U.S. Cold War project. A hill that disappears, revealing a secret passage!

Charlie,
I can lift it off from the rear and set it down (Without the trees)
