Just gonna repost my #3 long spring mod post.
So bout a bunch of Vicor and Blake & Lamb #3's. Most of them had lam jobs all ready done ,but where missing chains,and of course now way to adjust pan tension. So after a few head aches ,some cutting and some grinding I figured out a pretty good way to revamp the Old long springs.
DISCLAIMER : NO, you do not need to do these mods to catch animals. Heck alot of these still had fur in the jaws when I got them. This is simply or those who wish to.
Under Hump Pan Tension.
So with this method were not really fabbing anything. The base trap by the way is a Victor #3 this. Was already laminated before i got it.
So first we need to take the pan off. Easiest way I found is to flip the trap upside down. And wedge open the crimp on the pan. Personally I just use a pair of small cutters. Clamp down and twist . A flat head screw driver works too.
Now put the pan over to the side you'll need it later. Now we gotta got rid of the little bar that the pan crimped too. A hacksaw can work jus fine but I just used a cutting wheel on my grinder. . Takes a whole 30 seconds but try to keep the cut as clean and flush as possible.
Now we're actually going to need to cut this gap down power on the side opposite of the dog. This is goin to allow the pan to drop all the way down in the orientation we're going to put the pan. The white soap stone mark is where were grinding to. Again just using a cutting wheel to make the main cut.
And with a little file work after cutting we should have somthing like this.
Now back to the pan. First we need to close the crimp back.
Next were gonna weld the seam and grind every thing flush. Do t worry about the hole too much where going to redrill it.
