What are the issues with stainless lanes. It looks like very nice trap.
The rubber padding falls out when the trap fires, the levers get jammed in the closed position, the pan breaks off, the swivel attachment breaks off the base, pan tension is very hard to adjust, there is no way to make fine tuning adjustments with the trap (like levelling the pan)...
Also I see when you made that set with the lanes rubber jaw trap you have the springs stuck straight out. Is designed to set that way. Most longs you crank the spring towards the dog to get the loose jaw to lay flat. Can you not set the lanes this way?
They are reasonably forgiving with which way the springs can be placed. I vary where they go based on the set - to avoid rocks/tree roots/ hard ground, to reduce the chance of the target stepping on the spring and maybe noticing something not right, to keep natural guiding in place...
I've got hold of a steel jaw lanes to trade. It's got a bit of surface rust but I will get a wire brush onto it and it should come up fine. Straight from a large cattle station up north. (Station = ranch)
