Springs for allwins

Post by geofflove »

I need some very small extension springs and can’t find a reasonable source. There are lots of mixed spring sets on eBay but all too big.

The ones I need are the light ones which return the penny trip lever on Oli Whales machines and also the spring on the ratchet lug.

Ideally a mixed set of tinys would be great as I know I’ll need various ones in time but if not if anyone know the rough spec and source of these particular springs it would be very helpful.
Cheers

I recently needed a long, weak spring for a Sega jackpot, & got one from here.

Took a couple of weeks to arrive, but was cheap & what I wanted.

I have made my own and it's easier than you might think using piano wire. It is the thickness of the wire and the spring diameter that determine the strength and you can get these dimensions from the one you want to replace. It takes a bit of experimenting to get the size of the mandrel right as the spring is always bigger once the tension is released. All you need is a speed controlled electric drill to turn the mandrel slowly while you feed the wire onto it wearing leather gloves to protect you hand. The mandrel doesn't have to be anything sophisticated - I used an old nail.

If you need an exactly specified spring, try Flexo Springs who have an enormous range to choose from and supply from stock in a day or two. Not as cheap as making your own but a top quality product. Their website is at flexosprings.com

Thanks. I’ve ordered some piano wire so once that comes I’ll give it a try. How hard can it be?! Lol.

It's officially documented that J&M use hardened piano wire for their skill system and main springs in the '30s. :cool:
