This is my (UK) version of Rock-n H Woodshop’s Exploding Bank – see

In the UK, one of the longest-lived mousetraps is the Little Nipper, and one of these is ideal for this project.
However, the dimensions are slightly different to Drew’s, so the sizes of the components need to be changed slightly (assuming 1/4 inch ply used):
Base 4 3/4 x 3 1/4
Sides 5 1/2 ( 4 1/2) x 3 1/4 (The slope IS pretty close to 15 degrees)
Back 2 3/8 x 4 1/2
Front 2 3/8 x 5 1/2
Top 3 x 5 3/4

2 off 1 3/4 x 1/4 (6 mm)

2 off 5/8 x 1/2 (8 mm) (I drilled 1/8 deep holes in the sides to improve glueing)

2 off 4 1/2 x 1/4 (6 mm)

The design of the Little Nipper has no doubt been tweaked over the years to its most efficient, but I found that a slight upward bend on the end 1/8 inch of the trap retainer bar made setting easier, whilst still triggering effectively with a coin (but larger than a 5p !). I also trimmed the sides of the cheese-mounting platform with a chisel so that they did not rub against the sides of the Bank.

Drew provided a great attention-getter with this project, and it has surprised and delighted a number of my friends. It will be given to my grandchildren as an extra Christmas gift, to use on their friends.
