Got my stearing wheel last week, but needed a boss to mount it so turned one up on my lathe and milled the hex in on my dads cnc, also needed to drill the wheel so marked it on his cnc so I new it was right, real happy with this as it not like you can buy them off the shelf
I copied the tapered hexigan from the standard sierra wheel
A stainless cover tube to hide the column, still not 100 percent how I'm finishing this bit yet
