Is chamfer for thread lead in totally broken now?

Hello, just trying to do very simple G-1/8 (BSP) threads, but I can't seem to get a lead in chamfer. I've found the multiple work arounds here and on YT, but none of them seem to work. 

I've tried:

Using the threaded hole tool with chamfered hole selected.

Making a hole, then chamfering it, then threading it.

Making a threaded hole, then offsetting the threads, and chamfering the offset round part on top of the threads.

Turning off Modeling of threads, chamfering, turning modeling back on. 

The last three were solutions in youtube videos that I watch them do, and they work in the videos when they do them, but all the videos are a few years old. Did Autodesk break even these workarounds? 

I saw a method of using Revolve with a triangle which I will try next, but that seem way too overly complicated for something that should just be a setting (that works, since it is already a setting under threaded hole, but doesn't cut the threads into the chamfer).

Your attempts are failing because BSP (whitworth form) have filleted peaks on the thread. The only way to chamfer a modeled BSP thread is to use a sketch and revolve cut.

Something like this.

Another thought if you have a lot of holes to chamfer is use another hole feature. Set the depth very shallow like 0.01mm and a 90° point. I complained about this 10 years ago and made a request on the old idea station but someone suggested the other workarounds so it was marked as solved, I pointed out it doesn't work on BSP threads but only silence! Doesn't seem to be something support are interested in.

Thanks Mark, that worked. It's crazy that they haven't added a seemingly simple feature like this, especially when it's critical for 3d printing which has grown exponentially over the past 5-10 years.
