Figure 1: I actually didn't use that exact layout
because I made mine from scraps. This would be a simple layout if you were
to make 16" diameter traps with 2 center braces 12" large. You'll need to
make 8 large circles, and 16 smaller circles to make 4 traps.
Figure 2: Here my friend
Steffen made a simple circle jig that fits on a band saw. It involves a
single screw that I put in the center of the circle. (Remember to mark the
center with a cross). We made two holes in the jig, one for a 12" diameter
circle, and the other for a 16" diameter. This proved to be very effective
in making circles, It was also easier and way less messier than using a
Figure 3: I had to cut about
24 circles but it didn't take that long considering how fast the jig pumped
Figure 4: Here we see the
circles and Makita hand drill I used. The nail gun will be used to shoot
some brads when gluing the smaller disc to the larger disc. (For the end
Figure 5: Using a jigsaw and
no clamps I just rotated the disc by hand making inner circles in the
smaller discs (To allow air to pass through the braces to form one big
chamber). Since we'll be using 2 inner braces for each trap, I made 8 of
the smaller circles into these donut shaped braces. I cut a 6" hole in the
12" circles so that left a 3" border which is plenty strong. With the
remaining 8 smaller circles you do not have to cut inner braces in them but
you could as it might cut the weight down of the tubes a bit. I just glued
them and nailed them in the center of the end caps. To find the center I
drilled a hole in the middle of the small disc and matched it with the
center of the large disc.
Figure 6: Remember to cut
1.5" from the inner hog wire because the end caps are both 3/4". If you
don't then the outer hog wire won't be able to staple to anything. Save the
scrap from the top as it can come in very handy when cut into "U" pieces
that can be used as clamps for holding the hog wire to itself as seen in
figure 9. Also, be careful with the hog wire as it is very sharp and
springy. I didn't wear gloves or pants like I should and ended up a few
Figure 7: Staple the braces
in place, it's easy if you rest it on the wire as shown. My friend and I
built these together to save time.
Figure 8: Cut the fiberglass
into sections to be wrapped around the wire. They should not overlap but
should bunch closely together to form a seal around the inner chamber. I
used two strands of twine I wrapped around the cylinder, tied, and trimmed.
Three sections will not cover the 4 foot length so I cut one section in half
for the top as seen in figure 8. When applying the 2nd layer, put the half
cut section at the bottom instead of the top again, and make the seam on the
Figure 9: We cut the excess
hog wire into "U" shaped pieces that were then bent to be used as clamps
that held the hog wire to itself. We did this because we had no wire but
will probably use this on the other traps as it worked very well. See the
first picture for where we put the clamps, it took one person to pull the
wire together and the other to bend the clamp in place.
I really think it's optional to seal the top part and
places where fiberglass meets with caulk. The fiberglass ends up being
bunched up pretty well so I only caulked one of the traps as an example for
those wondering what it would look like.
Figure 10: Wrap the outer hog
wire fence around the fiberglass. Then use the excess wire you cut from the
top as "U" clamps. The excess wire will make plenty of these clamps but you
could always make more with the extra fence. These will hold very strong if
you chose a strong welded fence.
What I did was staple the wire a few times on the sides
touching the floor in (figure 10), and then pull the wire together and
clamp. Put about 7 clamps up the seam, it's easy with the trap on its side
with one hand pulling the wire together and the other hand bending the clamp
in place. If you spiral wound the fiberglass tight this will be no problem.
Figure 11: Next, cut the
string if it's too tight and let if fluff out. Cut the polyester into 4
equal sections and wrap the outside with it and tape the ends. Sew the
burlap into four 4.5ft high x 5.0 ft sections and then wrap the traps and
sew down the seam. (May need a woman's help with this one). Staple the
burlap on top of the disc, and then you can add another decorative end cap
to cover the staples, or finish the trap however you wish.
