Extruding at an angle

[joe0121]

Supressor.pdfI am making a muzzle device. I used extrude to create square port in the muzzle break but they are 90 degrees perpendicular to the face I'd like them to at 30 degrees. In other words the port would vent the gas towards the back of the muzzle device.

Extrude from angled workplane

or

add Face Draft. (you might have to Split Face if you intend to angle the "doughnut" faces, not sure which end is front and which end is back)

Added a PDF for more context. The front would be the .600 round part ahead of the threads with the square holes.

What if you simply extrude a chevron shaped sketch?

That is the perfect shape. I'll play with it when I get home from church.

How is this feature going to be manufactured? I think you are going to have to change to a cylindrical drilled hole.

I guess maybe you could make it as a cast part and then finish machine the cylindrical features.

I was going to put the piece in a manual mill and try a few tricks mention here http://www.practicalmachinist.com/vb/general/drilling-angle-193342/. It would end up having rounded edges which is fine I was just being lazy and creating a work plane than a square and then extruding the square.

I worked out on the shop floor for 8 yrs as a machinist. Model features for manufacturability.

Fair enough. I do most of the work on a buddies old South bend heavy ten and vertical end mill. I was out there Saturday and quickly learned Parts are much easier made on the computer than they are on the mill.
