Gear shift knobs

Yesterday I went to Industrial metal supply and picked up 2"x12" round aluminium bar stock. Today spent most of the morning cleaning and oiling my dad's lathe, which had not been used in about 30 years. Then I chucked the bar up and turned out 2 different gear shift knobs. I have a pilot hole, but have to wait until I get home to make sure I use the correct drill and tap for the shift lever. I don't know yet which one I prefer.
