to cut the bottoms out. Wanting to get at least one house done without
waiting another week I picked the one that I would not want to use a
router on. Had run one test box with a couple of pounds of sand (real
sand) mixed in with the 13 pounds of plastic powder. Goal here is two
fold, test if bats can cling to this roughened surface. (Think they can)
And to eliminate one wooden baffle.
Since the inside of the outer shell has such a rough texture there is no
need for the inner and outer 'rough on only one side' baffles. Replacing
these two with one more double sided baffle.

As you can see it looks like a light weight 5 chamber house. Looks can be
deceiving since the recycled pallet wood I used for this test box is
quite dense. Noticed the box getting heavy as I slid the last few
partition slats in, so I got out the scale and weighed it. 50 pounds!

Will need something to keep the baffles from sliding out while in use. My
first thought was a simple block of wood and a few screws. Will
galvanized be good enough in this application? Or since these will be the
only four screws holding the house together try to source some stainless
steel screws? Stainless bolts are are easy to find but quite expensive.
