I am reworking the frame rails for my crawler, but, it has a twist in it. Here is a short video that should explain what I mean.

Part of the reason I wanted to rebuild these parts was the same twist in the old parts.

I tried to carefully drill the two sides while clamped together in the mill vise.

I tried to carefully turn the spacers in the lathe. The order was...

Chuck the stock in the 3 jaw, center drill, drill center clearance hole to size.
Turn outside diameter down just enough T to make it round and concentric to the center hole.
Part off. I faced one of them to match the length of the first.

I DIDNT machine the inside mating surfaces of the bar stock.

If I loosen the clamping screws a bit and tweak it as I tighten it is better but I want to try and figure
out what I might be doing wrong.
