Looking For Scale Clamshell Bucket Plans

[PittsfieldPete]

Hello:

This is my first post. I’d like to retrofit a Huina 1:14 scale RC tracked crane with a clamshell bucket. Preferably I’d like a bucket that opens & closes automatically, similar to the type used on Tonka & Nylint toy cranes. Apparently the toy buckets use a simple sliding mechanism that closes the bucket automatically when a load is lifted, then opens it when a release trigger on the bucket hits the boom at the top of its travel. The attached photos show details.

Tonka & Nylint buckets are too big & toylike to look right, plus they’re far too expensive to buy just to reverse engineer the open/close mechanism. Does anyone know if plans are available to build scale model buckets fitted with an automatic open/close mechanism? If so, please let me know.

Thanks,
Pete
