How to model and machine a pocket for this?

[fritter63]

I know that there has been discussion about modeling tapered pipe threads, but wondering if there is a way around it for this?

This is a threaded insert for wood. It is tapered slightly towards the bottom.

I've already been able to model it as a 3D body, then use that to cut the target body to create and accurate pocket for it. This works except that without the threads cut, I need to install it using a special jig I made to keep it straight while starting the threads. Otherwise it can end up a little crooked.

So, it there any way to model a tool path with a thread cutter to have it cut those threads (even if it's not F360 threads?). It's 9 TPI, very coarse.

Thanks.

If you get the right thread mill I don't see why you wouldn't be able to thread mill it.

Also I created a screencast of creating tapered threads for anyone in the future who might find this post.

Thanks @XanderLuciano

This was very helpfull

Although, I was actually able to machine the threads by simply using a 2D thread op, selecting the tapered hole, and just specifying the right thread pitch. I didn't realize it would

work on tapered geometries like that!

After machining, the threaded inserts just screw in nice and straight without have to use any kind of a guide.
