| Looking to replace the tailstock (Proxxon PD400), need something more rigid |
| (1/3) > >> |
| Lester:
I've been running my PD 400 for several years now, generally very happy with it. The only ointment on the fly for me is the tailstock. I mainly turn aluminium, brass, and acetal for toy boats, and sometimes small stainless. The tailstock simply won't carry a 10 mm drill bit into aluminium without wobble. I think the rest of the lathe is up for this, so am looking to source a better tailstock. Does anyone know where I might look, please? Many thanks! |

Lester, Just been looking at the spec for that lathe, and the cost (£2000 +vat), so one would not expect it to wobble. Have you identified exactly where the wobble is occurring ? By that I mean is the whole tailstock moving or is it the tailstock quill ? Also, does it do this if you drill up to 10 mm incrementally ? I'm assuming it isn't something silly like a bent drill. Dave. |

Lester have you tried stub drills, after piloting it with a slocum type? The slow spiral aluminium drills work well but need lots of WD 40 to lubricate. |
| chipenter:
Iff a drill is not sharpened corectly it will wobble regardles of the tailstock , have you tried a new drill ? |

Is the tailstock accurately aligned with the spindle? I had a problem on different lathe where the centres did not align causing centre drill tips to break off ( the tiny ones). Also made my drilled holes oval. |
