We made great progress today. We set the manifold flange on the adjustable angle table (most big drill presses have this built in). A sketch showed I needed a 24 degree angle on the outer holes and 13.5 degree angle on the two inner runners. I used a dial protractor and buble level (the mill table is level) to set the angle on the work piece. We cut the first hole with only minor problems. A huge volume of chips was produced which we cleared by hand with the machine stopped or running. Neve do this by hand on steel chips. We got a nice clean hole with a good surface finish on the wall ready to be solvent welded to my 2 inch ABS tube runners. I did shoot a video. When I get it edited an shortened up I will post a link to it in my Journal. Can you do this on a big drill press. I think so. The Grizzly insdustrial bit was very sharp. Chip flow was good upward. I would clear chips every .050 inches without coolant.
