So someone I know has me making some parts for his 66 mustang, one of witch is the stearing wheel, compleat with finger grips. So I started with a circle jig for the out side of the wheel. Then comes the jig for the finger grips. First step is figuring out the spacing of the finger grips, then the math to lay out the center lines of the finger grips on the wheel blank. Then I drew a straight line from these marks to the center hole from the circle jig, then a mark 3” in from the edge, and drill a hole. Now we can put the blank in the jig, it consists of a pice of ply wood spacers the same size as the blank a router slead. There is a nail though the slead the blank and the plywood, there is also a nail through the hole in the blank on the center line. Now all that is left is to router in about an inch or so, move the pull the nail on the center line spin to the next line repin and repeat. When this is done now you go back to the circle jig and cut the inside of the wheel, and sand. This is the first wheel Ive made and it was a challenge but fun. Just waiting to get the metal back from cromers to finish it.
