It calls for 3/8" mortises for all the 30 spindles plus a couple other
parts. Don't have a mortiser so how do I drill square holds without one?

Drill it out with a 3/8" Forstner bit then clean it up with chisels. The
first m & t project I had called for about 50 joints and that is what I did.
.. It is possible to use a router and square it or make rounded tenons.
