Nick, I would prefer not to swing the head to an angle. I would only do that if I had a lot of parts to make, all the same. Other than that I would use something like the digital one, or angle blocks or a sine bar. or even just a simple protractor will do. It all depends on what accuracy is called for on the job. Most of the angled stuff we do in the shop doesn't require super accuracy, near enough is usually good enough. But sometimes it has to be done spot on, hence all the different devices to achieve what is required. I am just finishing up digging out my shop, and the first thing I will do is retram the mill. It isn't far out, maybe only a couple of thou, but enough to cause me to change my machining techniques at this time. The tram got knocked out of wack when I was playing about with the horizontal milling attachment. So big machines can still be affected by cutting big chunks out of metal. John |

As I said, the first chance I get I will retram my mill. This first shot shows how far it was out, just over 0.1mm (0.004") over about 8" (200mm), not a lot, but enough to cause a problem. A couple of minutes later, it was back to spot on. Now a very happy Bogs. |

Hey John, would you explain how to use that tramming device please? I'm sure it's obvious but I must be really dense this morning. Milton, needing edjumacate'n...as usual. :scratch: |

Milton, If you want a short read on how to set up, go down this post a bit http://madmodder.net/index.php?topic=822.msg5591#msg5591 If you actually want to make one, read the topic from the beginning. http://madmodder.net/index.php?topic=822.0 Bogs |
