Hi
I dont think its for making springs, its used to tension clock springs so they can be taken from and repaced in their holders safely.

cheers

Those clock mainsprings can easily break ones fingers!  :(

Hi Joe,
     I am going to make a mainspring like you designed. I having been working on clocks since I retired nine years ago. I first bought a Webster winder. Sold it and bought a Ollie Baker style, Needed three hands to operate. Sold Ollie Baker and purchased another Webster. I have a small machine shop. My questions are:

What is the width of the spacer board when you route the barrel teeth mortice?
 
What is the radius of the mortice cut in the clamps (H)?

What size flat head machine screws do you use for holding the spring while winding?
 
    Thanks

Very nice thanks for showing.  :clap:

Width of spacer = 1 1/2"
Radius of mortise = 1 3/8" (Depth = 3/16")
Flat head screws = 8-32 X 1/4"
