Drilling Steam Passages
Eccentric Engineer posted on Facebook, December 2015:
- When cross drilling steam passages... It seems it's much easier to mill at an angle than it is to drill at an angle. Mill out the pocket at the same angle as your drill angle. Will save your drill from wandering.
Eccentric Engineer showing poor results from trying to drill steam passages at an angle.
Eccentric Engineer showing much improved work when the port face is first milled at the correct angle, then passages are drilled at 90 degree angle to face.
