Series of offset holes meeting at an angle, set up and machined them to continuous holes to improve product flow. These rings are from a hopper system to pour product into a pail with a liner.
First two rings were straight so not as complicated to set up, but last one (shown pictured) was angled so required an angle plate as well as the rotary table.
Dial indicator to make sure that ring was rotating true to centreline axis. Rod dropped through holes and angle adjusted til rod was centred top and bottom holes.
Side view showing rotary table mounted to angle plate. Note to self, need to get or make a larger angle plate!
End view of rotary table mounted to angel plate, yup, still need a bigger angle plate.
Another view of setting the angle and making sure that ring was concentric to table.
Final reamer size to make sure that everything cleared. Had to drill out in a few stages, 3/4, 7/8 then reamed to just under 1 inch.
All three rings, first two the holes were straight, so did not need to mount on angle plate, third was offset and had a jog where the holes met, so had to drill at an angle to give a straight hole, although at a slight angle.
