I believe there's a few different ways smiths will blueprint, that video uses tools which reduce much of the work that can be done without a lathe, though obviously some was still needed. If they had a tool to cut the face of the action a lathe would almost not be required at all.
ATR in Calgary blueprints actions and the cost I think runs around $500-750, and they don't like doing work on anything (rebarrel etc) unless they blueprint first. Other smiths do this work as well obviously.
If a guy had a couple actions they wanted done, I can see that having that kit and access to a lathe would be well worth the cost of the kit and their time, not that professional work and tooling isn't worth the costs in contrast.
One thing not mentioned in that video, is often when the barrel threads are re-tapped, they are tapped slightly larger than factory because of the alignment. If you plan to blueprint an action, keep this in mind as the barrel ordered should have threads cut to match the new threads, which may be thousands of an inch larger.
Edit: as much as I like Larry Potterfield, I think he may have made a mistake in that. If you skip to 3:30, look at the bushing he has used at the upper end, it slides down the shaft of the tap, the tap is no longer centered to the centerline and is chasing/following the threads. you can see it sliding down while he is tapping.
