I wish I had known about how to do this a while ago! I ended up having an oddball taper that I ended up having to buy an expensive reamer for. Good to know I could have just made one cheap enough :/

Pay dirt! Thank you! I was assuming something like this. I’m interested in making one and seeing how well it works.
