Jack - the excluders are easy to make. I make mine out of the plastic coated aluminum clothes line wire (I think it's #9). Put it in the funnel and hold it in place with four 1/4" hog rings, one on each corner of the excluder.
Thanks. That worked great. Got all my pots done today (10
). It sure was easier then trying to bend the wire around them like the guys do when building the pot. I'm thinking these might increase my catch too. I didn't realize how out of shape, round, the funnels have gotten.
