Acme 7/8-6 tap threading questions

[Illinoyance]

In my many years in the shop, I have never used an Acme tap or die. I always found single pointing to be easier.

If you can get the part in your lathe, single point the threads. Make the threading tool.

I'll stipulate that is way above my pay grade, but, I'm working on it

If you have cut other internal threads, the only real difference is the tool shape. Set your compound at 14 deg. off perpendicular.

I found a part that I think will work for me, if it does, no need to reinvent the (mariners) wheel .

While I don't specifically need a shaft collar, the one below from Ruland has the correct threaded bore, and near-perfect external dimensions. I won't be able to add 4 spokes to the wheel, but I can add 3 spokes which is fine for this application.
