    Default need large flat spring for old playground toy

    I was wondering if anyone knows where i can have a spring made for an old playground toy that i restored for the kids. There is a place here in town but they have no interest in making me one or a couple of them. i’m guessing the spring is 5” wide, bent in a “U” shape with a couple mounting holes top and bottom. I can get specifics if i can find someone willing to make me a few. i included a pic of what the spring looks like on another toy. the part for the kids feet is a separate piece and i can easily make that.

    I have seen similar toys mounted on a tall coil spring. A flat spring is less likely to catch and crush little toes and fingers. The ones I have seen have more then 2-3 inches between the coils. I wonder if a coil over shock absorber spring would be too stiff. Can the spring force be reduced by tempering?

    Seems like a car's rear suspension leaf spring could be heated and bent to the correct shape. Maybe that place that doesnt want to make one would at least be willing to correctly apply the correct heat treatment.

    That would be my suggestion also. A full service spring shop has the ability to anneal, bend, punch mounting holes, and re-heat treat.

    A lot of farm tractors from the 40's and 50's had a similar spring for the seat suspension.

    Go to a local farm tractor repair facility and see what the head mechanic says. He could probably tell you which tractor that spring is from and be a good help on sourcing the spring.

    Some farm disks use them, can't think of what brand. Spring is used between gang and where it mounts to disk frame to give some flex when hitting rocks.

    Wouldn’t a 5 inch by 1/4 flat rolled to the curve work ? Cannot imagine a 50 pound kid could make it “yield” just keep the big kids off it

    Carts and wagons often have sprung bench "seats",suspended by two C springs.....as there is a huge resurgance of horsey stuff,I d ask a local horsey person for a guide.......One of the few spring works left here charges $200 for a single plain spring leaf ,out of budget for a toy.
