A guide to designing and building a 3
bank of enclosures.
About 18 months ago I had the need for
some new yearling python enclosures. Initially I thought about
purchasing ready-made tanks, and then just adapting them to my needs.
After lots of looking around, I (like most reptile keepers before me)
came to the general conclusion that pre-fabricated reptile specific
vivariums are extremely over priced, and more often than not
inadequate in their design. So after some deliberation, I decided that
I would attempt to make my own. A decision that I was extremely happy
about upon completion of these new enclosures. What follows here is a
step by step guide, showing how I designed, then created this 3 bank
of enclosures.
Firstly, lets
consider the advantages of a home made enclosure:
-
The size is made to
your specifications - It is the size that you want, so it
fits in that tight space between the wall cabinet and the lounge (or
in my case the wall and another set of existing enclosures). It
is also a suitable size for the species that you plan on housing
within it.
-
It is finished in
the colour that you want - and therefore fits in with other
pre-existing pieces of furniture in your house.
-
It has all
the electrical wiring (for heating, lighting, UVA/B and thermostatic
controls) that you desire. Some people don't like the idea of an
incandescent bulb flashing on and off because of a thermostat, while
they're trying to sit and watch the TV. So you can wire in a heat
mat, a heat cord or a non light emitting ceramic bulb as you see
fit.
-
Any enclosure that
is built by yourself is going to cost a hell of a lot less than
one that has been marked up by a manufacturer or retailer.
-
And of course, you
will have the satisfaction of knowing that your animals are happily
abiding in an enclosure that you have built yourself!
|
Alright, now lets
get down to the nitty gritty. The 3 bank of enclosures that I
built is approx. 180cm high by 72cm wide by 51cm deep. Each
individual enclosure is approx. 55cm high. As soon as I decided on these
dimensions I sketched out a 3D drawing - just using MS paint.
Sketching it out like this helps you to visualise things a bit
better. As soon as I sketched this up, I printed it off, and added
in the dimensions.
For me, the
timber of choice was furniture grade ply wood. I used different
|
 |
|
thicknesses for
each part of this unit. The exterior sides are 12mm ply, each
"shelf" is 9mm ply, and the backing was made out of 7mm ply. These
thicknesses made for an extremely strong unit. There is no give in
it anywhere, and by using these lesser thicknesses where I could,
I saved a few pennies. I purchased the bulk of my wood as well as iron on
veneer which is used to complete the cut edges of the ply, from
Mr.
Ply&Wood. They also cut it all up to my specifications. This was
the hardest part done for me, and the most expensive part
concluded. |
My next trip was to
Bunnings. There I purchased all of my screws, glue, the lengths of
timber used for making the top and bottom lip of each individual
enclosure, a few lengths of 12mm x 12mm quad which were used as supports
for each shelf, as well as the pre-routed timber moulding that I used
to finish the the top and bottom of the completed unit. Finally I
grabbed a couple of bits of timber that were used to finish off and
hide the gaps between each individual enclosure (more on that later),
and of course some stain and varnish.
Now on to the fun
stuff! Using a dry iron set almost on the hottest setting, I ironed on
the veneer edging. This stuff is made with a heat sensitive glue that
melts and binds to your timber at high temperatures. It is extremely
easy to apply, and dries very quickly. I then used a sanding block and
a sharp utility knife to cut and then sand back the excess veneer. I
only bothered to apply the veneer to any edging that I would be able
to see when the unit was complete.
|
Once I was happy with the edges, I
then took the 2 side boards, and starting from the top of each
piece, measured 9mm down (remember each shelf is 9mm thick), made
a mark and attached a pre-cut length of quad using screws and wood
glue. From there I measured 55cm down,
attached another length of quad, and repeated this twice more.
You'll notice that at the very bottom, there is a small gap
remaining. This is because I prefer my enclosures to not sit
directly on the floor, and so they are all raised up 3 - 5cm. |
 |
Each shelf
was attached directly to the quad using screws and wood glue. You
can see here that rather than having one piece of wood between
each enclosure, I made a gap between the bottom and middle
enclosure, and another between the middle and top enclosures. This
I did for a couple of reasons: |
|
1. All the electrics for
heating, and thermostats could be easily hidden. 2. I could put
foam insulation between each enclosure, allowing different
temperatures to be more easily maintained so that I could house
different species in each enclosure.
At this point I also
attached the top and bottom lips. The bottom lip is most necessary. It
prevents substrate from falling out every time you open the glass
doors, and also helps to stop it from building up in the tracks that
the glass runs in.
The top lip is just a personal preference. the timber for this was
cheap, and I figured that the more I used, the less I would have to
spend on glass, which is more expensive.
|
The gaps at the front of the unit
and between each enclosure were then finished off with a couple of
lengths of timber that I cut down and then nailed over each gap.
The two lengths of timber moulding cost me around $15.00 each.
these were measured and mitre cut using a drop saw to create an attractive finish
at the top and bottom of the unit. These were just nailed and
glued into place. |
 |
|
Each individual
enclosure has its own backing. By maintaining those gaps at the
back, I could access all the wiring for the heat lights and
thermostats that were to go in down the track. Each individual
piece of backing timber was attached with a combination of screws
nails and glue.
|

|
Finally the unit
was structurally finished. At this point all of the screw and nail
holes were puttied up and the entire unit was sanded back (fun!).
Getting to this point took me less than a day, doing most of it by
myself and not rushing at all. |
|
By far the
slowest part was staining and varnishing the unit. 6 coats of
stain and varnish were applied over about a 3 week period. On top
of this I applied two coats of clear estapol to the interior of
each enclosure. |
 |
Somewhere in the
interim I made another trip to Bunnings. This time I bought plastic
tracks for the glass, liquid nails, plastic vents and some clear
silastic.
|
For ventilation I
used a hole saw and cut a couple of equidistant holes in the
top-back of each enclosure. These were then covered with plastic
vents, that were screwed into place. Glass tracks were attached
using only liquid nails. This stuff - as the name suggests bonds
tightly, and is more than adequate for this purpose. Finally, each
join within each enclosure was sealed using a bathroom grade
silastic. |
 |
The measurements for
the glass were made as per the guide that comes with the plastic
tracks. these were then taken to my local glass cutter who cut up, and
ground down the edges of 6 pieces of glass, which when I took home,
magically fit into place. the heat lights and thermostats were
installed by myself. This sort of thing should be done by a qualified
electrician under normal circumstances unless you are completely
confident with what you are doing.
The pictures below illustrate the final
product. For approx. $400.00 I have three custom built enclosures
that are fully wired up, and in my opinion look fantastic! I use Oz Black ceramic globes hooked up to a seperate
mechanical thermostat for each enclosure. The light cages were made
from stainless steel security door mesh, which were a royal pain in
the rear to make. The top enclosure houses a yearling male M.
bredli, the middle enclosure has a female of the same species, and
the bottom enclosure has a yearling diamond python (M. spilota).
