| BOXFORD IMPERIAL DIAL |

Griff, if imperial then they're most definitely Acme thread form, most likely 10 tpi single start(100 thou per rev). The metric screws will be Trapezoidal (TR) thread form. OZ. |
| GRIFFIN:
Thanks for that Oz, That's one less bit of homework to do, I'll get a thread gauge for the dimensions and either buy or grind a tool and have a bit of practice on some scrap. Cheers, Griff. |
| Manxmodder:
Griff, these inserts and tools are what I use for Acme threads,and a good number of other forms. http://www.shop-apt.co.uk/acme-29-external-threading-inserts.html Tools to hold inserts. http://www.shop-apt.co.uk/ser-external-threading-tools-apt.html 16 ER insert and suitably sized tool shank to fit your toolpost,I generally use as big a tool shank as my tool post/centre height will allow. On the Harrison that is 25mm square. OZ. |
