I needed to make some very small springs that are hard to find. It was too expensive to try and source these compression springs.
This tool will allow you to make very small compression springs.
I'm using a hand drill to run the screw. But you can use your hand, screwdriver, Allen key, etc.
It is designed for 3.8mm diameter spring using .009 Steel Music Wire.
You will need:
(2) M3x30mm Screw (Holds pressure plate)
(1) M3x50mm Screw (Main spring winding screw)
(4) M3x10x5mm Threaded inserts
(3) 22x22x3mm Aluminum plates with through holes drilled where shown
(Or you can just simply use the 3d printed pressure plates. They work just as good.)
This rig can be modified for anysize spring. Simply drill out the holes to be larger and insert larger nuts or threaded inserts. Use appropriate screw for type of spring you want!
This is a work in progress as I will be adding a hand crank version, a motorized version, and maybe a version that has different sizes built in.
