Quick two hours for Dave. . .

 One 'punter' drops in his Soft-Tail frame and asks for a new back-bone with clean lines? I'll be back in a couple of hours, shouldn't take any longer than that?

 Frame is mounted to a jig and old spine removed. . .clock is ticking.

 New back-bone tacked in place and looking good. . .

 Dave lining up the neck and tack-welding supports in place. . . might line up straighter if he opens his eyes?

Everything in place and check fit for the motor.
Dave takes the rest of the two hours to finish all welds and neatly grind for a smooth finish.
Time taken?
