Hi Chris

Excellent idea on the lead screws and workmanship. I’ll be following your build with interest as I think an excavator will be my next project.

Good luck

Getting the rest of the cylinders assembled, couple more set screws to go...

Got the last bits on the cylinders done, time to start working on the booms. This morning got the side panels cut from some 1/8" aluminum plate:

And started riveting on the angle stock to hold the top/bottom panels. Those will be screwed on, with screw blocks inside the angles since the angles are just aluminum. This will let me access the insides to get at the gearmotors.

Its coming along nicely!

any reason for using aluminium?

how do you know your rams will act fast enough? can you speed them up if required with more voltage?

keep up the good work !
