Specs on coil point spring?

Post by KWTownsend » Tue Jan 16, 2024 3:29 pm

Last fall I picked up a bunch of rusty coil hardware and have been cleaning it up, chasing threads etc. Unfortunately most of the springs are bent or rusted beyond use. If I can find the specifications, I’m sure I can find some new spring for a reasonable price on line.

Does anybody have the specifications for the vibrator adjusting bolt spring, part T-6726?

I’ve tried several springs from McMaster and some from hardware stores and nothing was nearly as good as the Model T coil spring from Snyders. Everything else is too long, too short, too stiff, or to soft. The proper spring from a T parts vendor is relatively expensive compared to buying bulk from a manufacturer but is the best way to go. For what it’s worth, I’ve rebuilt over a thousand coils and this was my experience.

Keith, I agree with Adam.

I’ve found that more often than not the correct hardware is less from a vendor than trying to source them yourself. If, say, McMaster Carr has them you’d have to buy a hundred and pay probably 12 bucks shipping.

Keith, number of turns, free height and diameter of the wire should put you in the ball park. Once they are adjusted for gap, all the spring is doing is keeping the upper from moving. If you look at the newer KW coils, that spring is a lot lighter.
I know the voices aren't real but damn they have some good ideas! :shock:

If you want to save all the old coil hardware, cut yourself a length of clothes hanger wire, put the springs, standoffs, and nuts on the wire and then polish up on a wire wheel. Once cleaned, those old springs can be extended by outward pressure to fit your needs on coil rebuilding.
