Why do guys buy new traps and for wat ever reason think they wouldnt need too adjust the pan tension? I mean really do you think the guys at MTP or FnT know wat you want or need it set at? Lets get real
LOL I don't think anyone who has posted thinks that. I'm the guy who 2 years ago posted about this problem of pan tension adjustment and I've been at this a long time. Here are my expectations with any trap, I need for the very reasons you mentioned, be able to adjust the pan tension to what I WANT and have it STAY THERE! When I set a pan tension at 3# say, I expect that pan tension to stay at 3#'s until something pyhsical happens to that trap to change it! My Bridgers do and my Dukes do!
Here's the scenario-
I receive 4 doz MB650's and I like the trap. I play a little with them to get their "feel" and do all my prep work to get them ready to use. The last thing I do is remove the wax from the trigger and pan edge and set the trap pan tension the day before I'm going to start setting for the year. I do this and have all pans set at 2.5#-3# and I'm ready to rock & roll. I start setting my line and I'm having about every 4th trap fire BEFORE I walk back to my truck, maybe 20'!!

As the day wears on these quick-firing traps are really aggravating me so I turn around and pull the days work. As I'm pulling I find I've got a few traps fired sitting in their beds AND a few that must have had well over 5# pan tension on them!

I start doing some fact finding on the traps ASAP when I got home. The next morning I'm out resetting the line with my Bridgers and Dukes and that night I'm still working on finding out what the deal is with the 650's. I found the problem, as simple as it was BUT I had to spend considerable time proof-testing the fix on maybe 6-10 more traps before I was satisfied enough that I'd found the problem and my solution worked then I had to rework all 4 doz. In my opinion, apparently this trap is designed to need quite close tolerances and when 1 or 2 of it's component's tolerances are off, the dynamics of the trap's system is compromised. The fix is a very simple but nevertheless, a fact-finding fix was certainly necessary and that cost me time and time is $$.
