Also, as to "round keys", would two 5-40 (5 BA) screws
installed 180 degrees apart be proper for a 1/2" shaft
with half the hole in the wheel and half in the shaft?

Just an opinion but I think this is asking for some wobble afterwards.=20
I was always told NEVER to fix a pulley, handwheel or whatever to a =
shaft
using one or two opposite positioned setscrews but instead to place =
always
two at 120=B0. The reason is that the direction of the pull is on the =
opposite
side from them nicely in-between the remaining 240=B0. Giving a sort of
fixture equal to the tree legged milk chair.
Since you fix the two screws in-between the axle and the wheel and =
probably
in doing so put some stress, drilling and tapping, in that place I would
rather like to seen then at 120=B0
Don=92t know off hand the size of 5 Ba but one looks sufficient for a =
12.7mm
axle.=20
