as a side issue to an earlier thread is there a book / chart that i can look at that tells you the sizes you have to machine to put a thread on or into pipes particulary into pipes/ tubes new to this not engineering trained i'm only an engraver by trade so this is new i have used taps n dies but that is cheating thanks polecat |

If you download the Exel file from here you can sort the columns. External threads are just about nominal size or thereabouts, internal depends on the pitch, thread angle, and % of thread depth to derive the appropriate tapping drill / bore. There are loads of books / charts to download, you just need to search for the species of thread. Dave. Edit .... I'll try putting the link in .... pillock :bang: http://www.watchman.dsl.pipex.com/thread.html |
