An update on my milling machine. I completed it over two years ago and it has seen some use since then, not daily but quite often. Most of my work has been with aluminium but strangely enough it seems to be more accurate when I am cutting steel. (maybe I am being more careful?) One thing that has pleased me is that I have not had to adjust the squareness of the head. I have always worried that when I am rather ambitious with the cut that I take and the cutter jams in the work that it will pull the head out of "tram" . That does not seem to have happened, The marks left by the cutter seem to be square. The biggest problem is the Z axis. For coarse adjustment I move the table and for fine adjustment can use the slide on the head. The leadscrew appears to be approx. 2mm pitch (note "approx.") I need to fit a digital readout to it but finances restrict my options. Overall I am very pleased with my efforts, Definitely worth it! |

Great to hear Norman. It's a fine thing to use a machine that you built yourself! :beer: |
| NormanV:
Yes, it certainly does feel good. |

Honestly? Collecting surface rust on all that hand scraping. Buried under bits and pieces of odd stuff like old lawnmower parts, house wire, trowels, etc. :doh: |

Oh woe is me! After two years of using my milling machine I have a problem. Twice in the past when taking a heavy cut the motor has cut out. I assumed this was a thermal cut-out in the speed controller as it sprang to life after leaving for some time to cool down. Today it happened again, I have left it for a few hours but it refuses to work again. Wiring this up was at the limit of my knowledge, trouble shooting it is a whole new ball game! It is so frustrating, I am working on a new project that has come to a complete standstill. Wish me luck. |
