This may seem like an insignificant question but I'm asking anyway. I'm
building a high chair from one of Rocklers plans. It advises to predrill
for a dowel pin in the back post blank for attaching to seat at 90 degrees,
then cutting the bottom of post at 7 degrees. That requires drilling the
mating hole in the seat at 7 degrees. Why couldn't I just cut the post
first, clamp it in a vise with the bottom flush so I could just drill a 90
degree hole in both pieces?

The only problem I see with that is if the dowel post is small in diameter
and you cannot drill deep enough at 7 degrees relative to the post. If the
post is relative thick, you should be able to do it your way.
That said, ultimately it is probably going to be a stronger joint set up if
the pin enters the chair at 7 degrees vs. entering the post at 7 degrees.
I doubt the designer used 7 deg just for the complexity of it. I don't have
the plans to review but I would suggest visualizing the assembly completed,
perhaps from the completed picture and try to think of a reason 7 deg. is
used. Is 7 deg a good angle for the back tilt?
