This is the current design for the chainsaw drive and pivot. The middle arbour will be stationary, the centre shaft will carry the chain sprocket and the outer arbour will be where the bar mounts and pivots from.

The previous parts were the outer section and the shaft.
The lathe work is complete now to drill some holes for the bar adaptor and sprocket mount.

The centre section was 2 3/4 x 2 inch bore DOM, spun it between the 3 jaw main chuck and rotating tailstock chuck to surface it.

Then into the four jaw to bore it for the bearings.
