Stupid question...

A hook ..a set of weights and a kitchen or coin scales

[ChrisB]

Weights on a hook, I understand. What are the scales for?

[zzr1100]

So you can verify the weights !

[zzr1100]

Oh .. And weigh the hook

[Dave 101]

The cheapest way is to tie a piece of string to a plastic bottle , tie the other end to the trigger and fill the bottle with water from a cookery jug so you know the amount of water used till the trigger fires .

For as long as I can remember I have used a tin can with a wire hook and fill with sand 'till the trigger breaks then weigh the can, hook and sand on a set of balance scales measuring lbs and ozs.

Cheers guys. Will have a play.

I would try this but I can only buy metric sand. Will it make a difference?
