I would like to see the process!! What you figure your cost per trap is after material

about $2 to build each one... maybe a little less and about an hour on each... i'm sure I'll get faster than that, but just haven't built a bunch of um yet

material list: #9 galvanized wire 2" OD x 3/16" wall aluminum pipe 4 small bolts with lock nuts (not sure what size i used, just had um lying around) piece of 2" x 1/8" flat bar some 1/2" aluminum round bar if you buy all this stuff at regular lengths, you'll end up with enough to build about 50 - 60 dp's The first thing I did was cut a piece of #9 galvanized wired to 28"... then make a mark at 9", 13", 15" and 19".... the 13" and 15" marks are where you will bend it to make your outside edges of the spring... the other two marks are only there as a guide while rolling the spring, to make sure you keep it at the 4" length when finished rolling...

use a vice grip, of any kind, to hold it down while you make your 90 degree bend Attachments:

next you will put a piece of round bar in your vice... the finished piece will be only 3" long...but you can start with a longer length to get a good grab in the vice.... you will mark your 3"... then mark 1/2" from both sides.... then mark 1 1/4 from each side..... this should leave you with 5 marks including your 3" mark where you will cut it off later... once you have these marks, you will need to drill a hole at each mark... i think i used a 5/32 bit.. it's just a hair bigger than the #9 wire whichever bit it is...

once you have your 4 holes drilled, you will slide the ends of the wire that you bent into the two inner holes and leave about a 1/2" to 3/4" sticking out the holes... put it back in the vice and grab the part of the wire that is closest to the round bar and start bending it around the round bar... when you are about 3/4" around on the first turn, take a hammer and beat the wire in tight to the round bar... this will make it more uniform and easier to keep bending.... now keep wrapping your wire around the round bar until you get to your other two marks (the 9" and 19" mark)... these two marks will leave you with a 4" over hang of wire left sticking out... and that to me is perfect Attachments:
