Once i got back to it a month ago or so i started building the base of the boom and working to figure that out. I picked this tank turrett unit up for rotation hoping its strong enough to do the job

And my first attempt at the base was unsuccessful

Not strong enough

Then i went down to my snow plow buddies shop and got this bearing

And a one inch bolt i center drilled to hold all the wires in the middle of the rotation

This is overkill but i like to work that way! haha
Then i cut a piece of thicker aluminum to fit the gear and mounted it to the chassis

And it actually works haha. Surprised myself a little bit.
Then i started cutting and bending sheet metal to build the boom base.
