Return Spring For a 1/2 Ton Arbor Press

Post by pollys1dad »

I bought a 1/2 ton arbor press to use as a fret press for guitar making. The red one has a return spring on the side, so when the handle is lowered, when released will return to its starting position.
The other photos show the one I bought, it has a shaft collar and grub screw no return spring.
I Googled return spring all I could find was motorbike kickstart return spring.
The red arbor press I don't think he has the return springs machined up but buys them ready made, perhaps they are used on other devices.
If this is the case any idea where I could get a suitable return spring and what would I have to do on mine to fit it. What you can see on the side of the shaft, those aren't threads.
Cheers.

Probably the same spring motor as is used on drill presses.

A counterweight also works.

Commonly called a "clock spring" this side of the pond.

Yes. That is the way for Mr. Red. Heck. There is more. Heavy clock spring segment attached to top of ram (one hole drilled and threaded). Spring secured by clamping fixture at frame web.
