Hi Youngmiller. Visit the site fourteen acre wood. John B's site (A couple of posts above this one in his signature). It will show you how to make one, thats when I stole his secret plans from.

 

One thing I learned that has not been mentioned (I think). When balancing the seesaw, put the lock wire on first and then balance it across a piece of dowel to determine where the balance rod should be stapled. Otherwise the seesaw will be back heavy (although I used galanised fence wire which is heavy), I adjusted mine recently and it works much better.

This is a 'basic' one that a friend of mine has just made as another test of the plans. This is good quality marine ply and he's very good at this sort of thing - has a garage full of powertools.

 

(Edited to add that when I say 'basic' I am not intending any sort of slur on H's trap. It's just to distinguish this one from the 'Improved' design with all the sliding doors.)

Looks a cracking job. Wish I had the proper tools to make a better job of things myself, I must be the worlds worst joiner...

I have found that using an old bit of laminate flooring for the actual seesaw gives a much better sensativity regarding the seesaw.......

i've knocked one of these up myself now - all to speck as far as i can see, as above mentioned sensitivity of the seesaw is my only concern -

- mine ' swings ' and locks with a little push - (make your own jokes!) but how sensitive does it need to be? (dont want it so that it's catching mice, but do want some of the bigger boys - rats and squirels!

 

sorry, difficult question to answer i imagine.

 

cheers anyway!

 

(ps, big thank you to johnb for earleir posts regarding seesaws - am going to make a xmas present to myself of your book me thinks!!)

Fish is right - you can fine tune the whole arrangement by adding small weights to the see-saw.

 

The problem with the see-saw is that it acts as a lever, so the further past the pivot the quarry gets, the more downwards push it with generate.

 

So when the little mouse gets right to the very end he could be generating a relatively large amount of downward force. If you set the see-saw with too much counterweight them mousey may not tip the see-saw fully but stands a chance of getting the back end off the ground and buggering up the locking 'U'.

 

More importantly even a rat will generate a relatively small down push as it first goes past the pivot. What you want to avoid at all cost is a counterweight so heavy that it's even a twentieth of the weight of the quarry because then the see-saw moves too slowly.

 

My personal preference is to have the see-saw balance so that the back end is just heavier enough to keep it firmly down in the set position. In fact the see-saw is pivoted dead centre and it's only the weight of the locking 'U' that keeps the down ramp, down. Once the quarry is a fraction more than half way past the pivot it tips and there's no messing about.

 

You sometimes get things you didn't intend, but that's the beauty of a live catch trap. yes.gif
