I really needed a spine tester to evaluate my wooden arrows. So I built one up on Saturday out of bits that were lying around.
It's a bit on the rudimentary side, but it does work. I am going to modify it slightly to bring the pivot point, and hence the zero angle, down a bit. So the scale is not so canted up in the air.
It's made from a lump of 4x2, some brass rod and tube and a bit of 1/4" dowell. I used some lead wheels as a counter balance and a bag of metal toy soldiers as my 908gram mass, suspended by a bit of bent coathanger from the centre line.
I also had a go at creating my own scale, but eventually found the one pictured on the internet.
