To All:
I had a job this week where I had to drill a hole 14.7 degrees to the
base on a curved surface. It sometimes is easy to edge find from a
corner but if the corner has been filed, or had a chamfer put on it,
the edge finding of course won't be accurate. I used to have a corner
cylinder for doing this, but I couldn't find it. I was going to make
another one like the following, but decided it wouldn't be worth it for
just one part. Perhaps someone might make use of the idea for themselves.

Could have used it today on an angled fixture part I was
doing .Instead I left extra material, drilled a hole in the extra
material, reamed the hole and then stuck a gage pin in it. Then I used
the pinned hole to pick up my tool height for the next operations. I
also indicated the pinned hole with my Zero It (pin was parallel with
the Y axis) and then moved the known distance (which I determined in
Mastercam X2 MR2) to the chamfered edge and set my x origin.

Jon:
I believe I've mentioned before that an assortment of Tooling Balls
can sometimes be beneficial in single angle (and especially compound
angle work).

Please log in for more thread options May not be exactly the same situation but I sometimes use a different way to
pick up datum's for angled or compound angled holes. I take a ballnose and
plunge a dimple in the surface of a part with the center of the ball being
my 0 point on the surface. Then I put a ball bearing in the dimple and
indicate it with the head under desired angle. Works perfect.

Jerry:
That's pretty ingenious. It would work especially well when you can't
drill a hole for a tooling ball but have enough material coming off
your surface to make your "detent". I suppose you could super glue the
ball in the dimple for indicating at an angle (so you wouldn't have to
hold it in place), and just whack it free when you're done.
