||Before you bypass this article thinking
it is too complicated, let me assure
you it is no more difficult than building
any other piece of furniture. My wife and I
build aquariums in many shapes and sizes.
The 75-gallon corner unit in this article,
similar to the one pictured here, is one of
the easiest to build and one of the most
practical to own.
First, we’ll build the frame and waterproof
the tank. You’ll be amazed at how
well the waterproofing process works,
and how beautiful the result can be. Then
we’ll craft a lid, install the glass, finish the
entire unit and add the plumbing for your
beautiful piece of living art. The pump,
associated aquarium apparatus, the fish
and their care will be up to you.
Cutting the frame
The aquarium will have a substantial, durable
frame that will require some muscle to
cut and assemble. Handling 4' x 8' sheets of
1"-thick plywood requires an assistant or a
good set of roller stands (Fig. 1).
Cut both sheets of plywood to 65".
23" from the long side of one
piece, or set your fence to 23" and rip the
back left side. Mark or reset your fence to
24" and rip the remainder of that sheet
for the back right side. It’s important to
save all the offcuts for later use.
To cut the front panel,
lay the board with its best side down. Mark lines 9"
and 18" from one side; from the other
side, mark in 22". Rip the line you drew
at 18". Now set the saw to 45° and, with
the best side down, rip the 18" piece at
the 9" line.
Leaving the saw angled, cut the
remaining 30" at 22", making sure the
best side is down. You may need to set
up a fence to keep the angled board
straight. Turn the 22" board around and
rip the other side, keeping the best side
down, so that both sides are cut at 45°.
The best side should be the wider one.
Dadoes and windows
