Ahh, sorry Wilfried, I thought you were thinking of keys in the sides.

Well I got the picture right not in the side but in the face I just used the
ones in the side to express what I meant when I said I would go for the two
at 120 degrees. Whilst mounting the screws in-between axle and wheel you are
most likely to put some stress in which might upset the wheel alignment. Do
not know what size would be the best. If they show up at the front I would
go for a rather small one.

Wilfreid, I think Allen meant the key to go in to the face of the
wheel/axle, and not through the wheel into the axle.
-----------
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
