An easy way to evenly space the 6 rivet holes around the control pushrods is screw a 6 sided bolt into the end and use a square to line a flat up perpendicular to the table of your drill press, and drill the hole, then just index it to the next flat. If you have your control tube set in a V block, you can also set a stop for the head of the bolt to rest against so all the holes are the same distance from the end.
an old machinist trick
