Using a TAP as Thread Boring Tool

  • Published on: 21 February 2021
  • Using a tap to cut threads?! I know, crazy, right? But just you watch!

    In a pinch you can use a smaller tap of the right pitch to thread larger bores than the tap was intended for.

    I watch some foreign video's where the craftsman uses a thread tap they use on a drill press. Are those a regular bolt tap, ran slow, or something special you can buy. Thank You

    That's pretty cool I don't know that I would've thought of that.I can appreciate all the effort it takes for you to make the videos as well as you do. With the pandemic going on. I've had to make videos for my students and found that's a lot harder than one would think.

    Hi Tony. I have an unrelated question. Is it practical to do some limited milling on a lathe. I imagine some mechanism to hold work and move it horizontally through the cutting mechanism. How about the ability of the lathe to hold a cutting head?

    Anyone notice the Big Bolt with Rolled Threads used as a prop to talk about cutting threads?

    Hi, you mention a few times that your lathe cuts a bit of a taper, is there any way to fix it? And if so can you make a video?

    Add even more to that, note this: Take a 36 tpi tap, set the lathe to 36 tpi speed - and you get a single thread... set the lathe e.g. at 9 tpi and cut with the 36 tpi tap - and you get a 4 start thread.

    Hi Tony, I recently found your channel and have gone back in time and watched every video you have made so far. I hope to watch the ones that you have already made in the future some day! Not all of us can move as freely through time as you can. Really love your sense of humor and amazing skill set. I recently acquired my second lathe and my first knee mill and have been going crazy buying tooling and trying to get it all up and running. I would love to send you some photos of my setup sometime.

    @3:40, you say, '. . .but the business end of these are exactly the same as the external threading tool.'...You make 1 of 2 errors. The first choice is a subject to verb number error: '. . . the business end of these are . . .' should be, '. . . but the business end of these is . . .'...The business end is singular and needs a singular verb. That would be is....The other possible error is more logical. It's a subject of a later pronoun to verb number error. You should say, '. . . but the business ends of these . . . ' These is the key word here. These is a plural pronoun and logically should follow a plural reference, which here should be the plural 'ends,' not the singular 'end.'...All of this might seem nitpicky and pompous of me, but think about it: English is ever-so-much-better when correct. You should correct this.
