Convention says RH crank leads, but doesn't really matter. On my Simplex I went for a very light, (not tight !) interference fit, smeared with Loctite 601. I did turn down a section of the length by 1 or 2 thou. to give clearance for the Loctite.
I added a "french key,". 1/8 inch dia. pin in hole drilled half in wheel hub, half in axle.
