I quit building snares! I can't deal with it, too boring and by the time ive made a dozen ive not saved a dime, is just as cheap to order them pre made per my spec's from newt, rally or whoever.
I like the cam locks, with a loaded snare they are super fast, no tail catch's in these YET! Ive also started using a smaller loop in certain area's/sets, around a 8 inch loop, not as many dinky beaver make it through them and adults usually have the loop around the neck. Would cut down on your pelt damage.
Rubber whammy's are fine, ive used them and they work great. I since have just gone back to my twisted .14 ga. wire support as it's what im more familiar with and as said it's easier to work with than stiff .11 gauge wire.
Not sure why your making them 60 inch's long, will work but seems like a waste of cable to me. A 42-48 inch snare is plenty for beaver and like was said just cut the snare off and attach a new one to your extension cable.
Talking to you is like having to slap an old TV a few times to get the picture.
