Great job :thumbup: I may need to make a similar Acme nut, in the not too distant future. May I ask how you went about the internal threading? A fully-profiled form tool which left you with a flat at the bottom of the valley when you got to full depth, or a tool with a 29o point which, once at full depth, you shuffled along with the topslide on successive passes to widen the valley?

Nice job. That's some sharp (lol) looking threads. Very very nice. Eric |

Hi, Rdg Tools have them for £8.51, I just gave another bloke from in the US the link the other day, he ordered 2 and cost him $55 US dollars delivered. http://www.rdgtools.co.uk/acatalog/ACME_TAPS__LEFT_HAND_.html Dave --- Quote from: kvom on August 08, 2010, 05:37:52 PM ---a 1/2-10LH tap only costs $100 or so at McMaster-Carr. Looks like you saved some bucks doing the internal threading on the lathe. :beer: --- End quote --- |

Hi Andy The thread is actually a square profile the tool was slightly narower than the finished thread once it was cut to depth i slowly widend it untill a good fit was achived. I was talking to rob wilson he sugested making a silver steel tap at the same settings as the screw this would be used to finish the internal thread :bow: :bow: :bow: :bow: John |
