The cutting jig for the wing hubs is simply a small table saw sled (16" long by 13" wide) made of 1/2" plywood. The 5 miter gage boards in the inside are 3/4" by 2 1/2 " set at 35 Degree angle to the center line (where the blade comes up in the middle). 7/8" hub blanks are clamped vertically to the 6 stations directly over the blade. It helps to glue a vertical support to hold the blanks (90 degrees) up right. You have to make two passes with each set of hubs. ( One one on each end of the blanks and of course you must flip them over after the first cut while being careful to keep them oriented the same way as the first cut. ( don't accidently flip them around or you will have the slots in the same direction.) Here's the video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FLTYotEvtOY.html
