You will find many pages of discussion on this subject as well as some neat designs.

I used a thin (.010") sheet of teflon between mating surfaces. Works well, very smooth. |

I hope that there will be no undue criticisms but in Model Engineering Clearing House we have just had a surprisingly similar discussion. I raised the point that an adjustable boring head( the main subject) could be used just as easily as a very good ball turning tool. It does require a change of tool bit but that is all. You might want to have Two for the price of or building one. |
| PeterE:
I can only agree with Fergus above. The similarity between the two tools becomes very obvious when looking at the George H Thomas designs for each: (Links to the Hemingway kit pages for each tool.) The Boring tool: http://www.hemingwaykits.com/acatalog/info_HK%201030.html and the ball turning tool: http://www.hemingwaykits.com/acatalog/info_HK1160.html It also becomes obvious that with different shanks and different tool bits we get a very versatile tool with much use. :headbang: BR /Peter |
