The quality of the pictures are not so good, but i think you can see the meaning of it.
It’s so easy to make and it works.
You can replace the white plastic with a ball bearing like here below.
This idea is from Jaak Claesen. It’s to easy to think about it. I don’t know if it’s works , but the idea is good.
This leading can not made by your self. Ok the real hobby people can make it but not for this money. They are very cheap, but you need 4 for each ax. Oh i forgot something to say, please don’t get them out of the kitchen, you got a lot of trouble with your wife. I know it !
