How did you determine where the axis of rotation relative to the firewall and aft bulkhead should be?

I lined up the bottom of the engine stand plate with the bottom of the firewall. So the access of rotation would mimic rolling the fuselage on flat table. I then laid the aft end of the fuselage on an adjustable height sawhorse I bought from Lowe's. Whenever I rotated the fuselage the aft end would just roll a few inches on the sawhorse.
You can see the sawhorse at the aft end of the fuselage in the pic below

Really? Seems to me if you rigidly attach an engine stand with a single degree of freedom (roll) at both ends of the aircraft and the axis of rotation does not accurately align and go through both, then you run the risk of tweaking/bending the fuselage. If you only attach an engine stand at one end, presumably at the firewall, and simply let the aft end rotate on an adjustable height table or saw horse, then I would agree with you that there isn't much thought that needs to go into how to align the rotation axis.
Although now that I think about it some more, you can have a single degree of freedom on one end, but you will need 3 degrees of freedom on the aft end, hence the offset attachment from the OP's photos.

If you don't feel like building one, but one of these. I have one and it's awesome.

That's why is left the back of the fuselage on a saw horse
