I got tired of the flimsy Monkeyfist jigs available from large suppliers and made my own instead! This is the perfect tool for making monkeyfists with a machine cut steel base 6mm thick, and four movable 6 mm stainless steel rods fastened by 8 m6 nuts.
The base measures 8x8 cm and the rods are 18 cm long to fit everything from a one inch marble to a full sized pool ball.
You will not find anything this well made and useful on the market. Made by paracorders for paracorders.
