Can you get any more vague?
Your Jig. You clamp spearshaft and drill a hole for the flopper pin at 90 degree angle to the drill press table. You use a set screw to hold the spear shaft.
Your drill jig is a rectangle or square, that means the corners are at 90 degrees.
Ok, now lets talk the Tricut point. All the way about a circle is 360 degrees , Divide by 3 sides for tricut so you have 120 degrees for each side as you go around the shaft.
The angle of the tricuts from surface to surface is 60 degrees. Looking down the shaft you see a triangle, a triangle has 180 degrees adding up all 3 angles. All 3 angles are the same so we got special triangle where all angles are equal and same for the sides.
If your jig was set at 60 degrees vs 90 degrees you are headed in right direction. You could also think about 30 degrees for 60 + 30 = 90.
Another special triangle in geometry is a 30-60-90 for angles. Take the 60-60-60 triangle and cut it in half to get this one.
120 + 60 = 180 , half of the 360.
If you wanted a QUADCUT point. Angles would be 90 degrees. a four sided jig like yours would work.
Hopefully this adds clarity.
