I just finished the prototype tooling used to bend new chuck springs for the Ryther’s patent chucks as found on the Millers Falls eggbeater drills. There are 3 springs per chuck. The set of springs at the top in the pic above is the new set made using my tooling. The set at the bottom is an original set.
In the pic above you see the prototype jigs made from hard maple and the tools used to bend the new springs. After producing a quantity of springs and learning the strengths and weakness of the jigs I will design new ones to be made out of mild steel.
These springs are available for sale. If you need a set please contact me at my email HARDWARECITYTOOLS@gmail.com
As always thanks for stopping by and please feel free to leave a comment.
