I've been PROMISING
this for awhile so here we go! This post will be on how to properly modify a longspring trap. Included in this post is how to take out the majority of the pan wobble and slop and how to impart a SET and CRISP pan tension! BEST PART..how to do it CHEEPLY and easily. There are "other ways",brazing,cutting welding etc that are great, but NOT cheep or easy OR easier to do!!
For this pictorial we will use a #4 Victor double longspring trap.
AND our necessary tools, a flat file, a XXX fine 3point file, vice grips or chanel locks,cutters and regular trapping wire.
The next two pictures show they typical dog/notch set up on many traps.. NASTY!!! STEP 1.
We need to square off the end of the dog, and square off not only the end of the pan, but square up the pan slot as well.
Notice the pan slow is fairly shallow, we need to make this DEEPER
in order to get the 3 point fine inside here.
The pan squared up.. STEP 2.
Using the 3 point (triangle shaped) file, we need to cut a slight groove across the end of the dog as CLOSE
to the end as possible(if it is back a bit one can file down the end of the dog to take the excess away)..you will end up with a "tooth" all the way across the dog on the end.
STEP 3. Now we take the 3 point file and cut a similar groove into the top EDGE
of the pan, this requires the notch in the pan to be slightly larger to facilitate the file.
Hook them together and you have what is called a MILES TRIGGER
, this feature allows you a CRISP
pan break with a set pan tension...something difficult to achieve on longsprings.NOTICE
the bite between the two!!
OK...now that we have the Miles trigger down..we STILL HAVE ISSUES!!!!
The pan still travels before it goes off..and the slop/wobble is HORRIBLE
as usual.. WHAT
can we do???FIX IT!!
To eliminate the pan travel you need to use a pair of channel locks or vice grips and close up the eye of the dog. The dog needs to move freely HOWEVER
if closed up properly it will NOT
move forwards at all.. NO pan creep!!! Problem solved!!
NOW for the slop..NASTY SLOP!!
We're gonna WIRE the trap!!
We start this by using regular trapping wire..you need to thread it THRU
the top of the pan eye..then UNDER
the bottom of the trap. Usually 3 wraps on a #3, 4 wraps on a #4. On this trap we get only 2 wraps as the eye was cut down in a feeble attempt to eliminate the wobble.
When you're done, twist it with a pair of pliers or similar.
NOW try the pan...90% of the pan slop...AND wobble are gone!!
[color=Red]You NOW HAVE a double longsping trap that's comprable to a coil WITH better holding ability!!! A set pan tension, NO pan creep, NO pan wobble. AND CHEEPLY done!!!
Hope this helps some people out.
