tutorial-countersunk hole in cylinder

[BikeGuy]

Somewhere there was a post about creating a hole in a curved surface. While it's not too difficult to create a sketch anywhere along the hole and extrude, it's more time consuming if you want a countersunk hole since there's no reference for the beginning of the hole.

So for this part, I simply created a plane along the centerline of the hole and created a cross-section of the hole. Then I revolved the sketch around it's edge. Let me know if you want to know more about this.

Why not just create a workplane tangent to the surface and use the hole tool?

im assuming you are not actually doing a countersink hole but a counterbore hole right? you will not get a countersink hole right on a curved surface. If you define a plane above your surface that is perpendicular to your current hole, the hole button has a counterbore and countersink option. here are a few screen shots. the first pic i actually redefined the plane .

yeah you're right. counter bore is the correct term.

The reason that I didn't just create a plane and use the hole function is because I felt that the revolved section gives more control over the location of the hole transition. I guess if you're accurate with your plane and counter bore depth then that would work too.
