-olympic coke bottle
-bit of paper to stop vice from scratching bottle top
-a coin of your choice to check the thickness of the neck
Step 1: Shaping the Neck
With my piece of paper between both sides of the neck and the vice, i gradually adjusted the vice until i could feel the bottle neck forming into shape - checking every so often with a pound coin in the neck until i was comfortable with the shape.
Step 2: Finished
I made mines to hold all types of british coin except for the £2 and £1 coins - be creative and have fun!!
