I did some redesigning on the top of the
stand. Here you see 3 1/2 inch lag bolts driven into the leg posts.
On a few of the bolts, they stripped out when I tightened them, since
redwood is soft, especially when you screw down into the grain, so I
used 4 1/2 to 5" bolts where that happened. Each joint was glued. The
lag bolt heads are recessed into the plywood enough so they don't stick
out. There is also a washer under each lag bolt head.
Here you see a sheet of 3/8 (11/32!!! lol) plywood that will be laminated
over the 5/8 plywood.
I just took a can of the urethane foam to use as glue. Then the board
was screwed down with short drywall screws.
The first side boards of 2x6 redwood are glued and then screwed with
3 1/2" (1/4") lag bolts to the legs. You can see a piece of 1" styrofoam
(which will probably change to 1/2", which I'll explain later), that
I used to check the height of the top side boards.
Edit 8-20-08. If I did it today, I would
use bolts/nuts instead of lag bolts, wherever possible.
Here the second set of 2x6 redwood sideboards are clamped and glued/screwed
on. I shaved an 1/8 inch off the bottom of the top board and the top
of the bottom board with a table saw, to make a flat joint between the
two.
And this is the finished stand.
I found this board at Home Depot, and thought it was a great find. Does
that look like a fish or what?...lol
Here's another neat find. I think that pattern looks a bit like waves......
I made a frame out of 1x1's as a template to place the holes for the
legs of the stand. You can see the legs of the existing tank in the
middle, and the legs of the filter stand to the left. You can also see
the tree trunk (barely) between the two.
Here you see the 1" styrofoam sheet insulation that I glued to the sides
of the hot part of the thermal mass with polyurethane foam.
I thought more mass was a 'good thing', so I'm going to fill each side
with some used cinder blocks that came from a wall demolition, and put
bricks in the holes of the blocks:
Edit 8-5-2004. Several people
said that this was not a good idea, since water supposedly holds heat
better than concrete. So I did a little experiment. I took 2 tin cans,
and filled one with just water, and the other with water and concrete
chunks. Then I heated them both to boiling, and checked to see which one
would cool down faster. Well it's counter intuitive, I know, but the can
with the concrete chunks in it cooled down FASTER. It also heated up faster.
SO, those people were RIGHT, and I took all the block out of the thermal
mass a few days ago..........
