Right on Collin!
I have seen many draw bore scenarios (by others) go badly but like anything: if you get it you get it.
Draw bore in pre-assembly works well if you do not have the experience/confidence to do it on the horses. Scribers will wait to pre-assemble but square rulers following precise rules have succeeded for a couple of centuries.
There are lots of tricks and techniques and none are wrong as long as they work.
