I got around to taking a few pictures, 1st and 2nd photos shows the internal frame, door and trigger.
As you can see the workings of the trap are not attached to the 5" PVC pipe but if you look closely, you will see a small hole drilled in the PVC near the edge. You bait the trap, set the trap and then slide the working part of the trap into the pipe and then secure with a short piece of tie wire around the round frame and through the hole. The trap itself is made from 3/16 round stock, some 1x1 wire for the door and the springs out of a victor rat trap.
There are pipe traps out there. So why did I make this trap? I wanted a trap I could gas the skunks in the trap without carrying a gas chamber. I used these in the woods, sometimes away from the truck so I didn't want to haul around a gas chamber. I have had troubles on here describing dispatch so I won't go into it but suffice to say gas will fill the pipe if it stands on end. All other pipe traps have holes and leak.
Humptulips. So you use Koro traps for skunks now? Interesting. Both spotted and striped skunks? How are you setting them and what baits work with them?
I have only spotted skunks here so no striped. I did try to upsize one for a friend that had striped, but it didn't work with the springs I had and never pursued it farther. Always beaver meat for bait, smellier the better.
As for the KOROs that is a longer story.
Here in WA we can only use "cage traps, box traps, suitcase live beaver traps and common rat and mouse traps". That is the exact words in the law. We were able to use the victor rat trap for weasels but when the KORO rodent trap came out, I took up the battle to get them approved. At first, they said no but after two years of battle/lobbying we finally got a paper saying we could use them but only the rodent trap. It is the smallest KORO makes and because it is sold as a rat trap it fits the legal description of traps we can use.
I spent a couple of years experimenting to get them to work. We cannot significantly alter them, or they wouldn't fit the description of "common" which is what I argued the intent of the law was. I use them in boxes just like they come from KORO, but they have to be set upside down to make them work well. I trap spotted skunks in them on run poles and they are consistently dead when I look at the traps. Smaller ones usually don't move the trap. Big ones pull out of the box and end up hanging. Set right side up they are inconsistent with a lot of misses and live animals in traps. Other trappers are having good luck with them for marten and muskrat.
This is a WA thing we are forced to use because of the law. Anyplace else I would use a conibear, but it is keeping us trapping.
