I am trying to raise the voltage to 240 V so that I can power two computers with 1300 watts, each on ONE 15 ampere circuit.
I power four 15-A circuits in my shop via a 60 ampere breaker I keep in my main panel. I came ought to that 60 ampere breaker with three #6 wires (two hots + neutral) and a #10 ground.
Each of my PCs is 1300 watts.
So, all I need to do is wire the existing neutrals that are already on the bus bar (those neutrals which originate from each applicable circuit. In my case, the only ones on the bar), remove these from the bar, and place the neutral in another 2 pole 15-A breaker. Is this right? Will this allow me to connect 2600 watts to one circuit? Is all I need to do to add a two-pole breaker and move the neutral to it?

Hire an electrician before you burn your shop down with all those computers in it.
While I can try to educate you, the fact that there's PLENTY of information already available and yet you clearly have done no research or just don't understand your power system makes the above my succinct advice.
In short, neutral has nothing to do with a 240V (only) circuit in the USA/Canada system.
You replace two 15A one-space breakers with one 15 amp two-space breaker, and both legs are hot. You need to replace the receptacles on the circuits as well.
Alternatively just add 4 more single-pole 15A breakers and wire new 120VAC circuits to them.
Please hire an electrician rather than forge ahead half-understanding; or take a good long time to actually understand before you touch a wire.
