Hello Fellows! I have these rocker towers about half done. There are 44 pcs in all so enough for a 18 or 2 - 9 cylinders. The pieces still need the slot on top and the base to be profiled. You would just need to make a fixture with a 1/8 inch pin and 2 - #2-56 threaded holes to finish up on the mill. I did ream the threads almost out of he hole in the center of the tower thinking I would do it that way. I have changed the way I'm going to do the rockers so if you want a head start on this part, they are yours for the cost of shipping. If more than one person wants them, I will send 22 to each person. Act now, garbage day is Wednesday night.
