Default Re: 90 ton 1/14 metal excavator scratch build w/embedded PC

I've tried to construct a bucket without welding. It looks pretty ok and feels strong even if I've just printed it in ABS for now. I'll mill these parts in 10mm aluminum shortly. But I just had to print one to see how it fit. I think it's a little wide, so I believe I will make it a 5-teeth one instead of a 6-teeth one.

The construction uses a center slice that is tapped with M3 thread. All the other parts just have a 3.18mm hole in them.

10 M3 60mm long countersunk bolts are then inserted from each side, and bolt into the threaded center slice.

Bolts are added to odd-number holes on the one side and even-number holes on the other side.

The good thing about this approach, is that the width of the bucket can easily be changed. It would also be super simple to create a sifting bucket.
