I need to do the same thing. I have a thread where I was tuning all summer with frustration. Could not get it right. where did you get the spinal fluted tap? What size and and part number?

Amazon is where I bought the tap. It’s a 6-32 size. I’m sure there plenty of other places to buy from. Just take your time with the tap. I used some cutting oil and went forward just a little then backed it out a bunch, back and forth I didn’t want to break the tap off. But it went well and was fairly easy.
