Hi Ade. Been sort of quiet for some time. Where are you hiding? in piles of wax I think :lol: :lol: Me /we need some update on your great project. Crankshafter |
| AdeV:
I've been putting it off (see the keypad thread), because it's time to move to aluminium.... but before I start cutting I need to clean & tram the mill... so that'll be tonight's job, now that the keypad is done & I can't procrastinate any further! Hmph, 3 hours of cleaning and tramming.... no cutting tonight, you'll have to wait until tomorrow.... :dremel: |

Right. The adventure begins again, hurrah! First, I lobbed the aluminium onto the mill, got it reasonably square & in a position where the cutter can reach all four sides (not sure about the tabs, I think they're still out of reach, just). Milled some straight/square/smooth "index surfaces" onto the front corners; I can now use these to set my reference points: You can see the index surface, near the "0,0" legend (which, thanks to my very expensive medical education*, looks more like "p,v" in the photo). Current width is, approximately, 261mm. I'll remove 6mm from one side & 5mm from the other, to make best use of the tabs later on. The full length is 560mm, I'll take as little as possible from the front edge (just enough to make it square), the remainder from the back edge. The reason, again, is due to those tabs; because the piece was cut out of a disc, there's an angled edge on the front tab, I need to maximise the overall width there as best I can, so I don't have to make an add-on piece later. It's tricky to explain without a crap-o-cad... maybe I'll do one of those tomorrow instead of working... I found a use for the memofix too (well, I read it in the manual): Flick the memo switch to "stop when you get to the index mark and act all broken", move the table until x & y lights are lit, and write the numbers down (you can see them near the left-hand clamp). Now I can power off the mill as often as I like; when I start up again, just flick the memofix switch to "broken", move the table until the lights come on; type the numbers into the DRO & put the memofix switch back to "working": And presto, as the table crosses the index mark, the counter resumes. So now I don't have to edge-find every time I power the mill off. Nice one, Dr Heidenhain! Tomorrow: some cutting :) (* OK, I lie, I never had an expensive medical education. I just write like a doctor. Very very badly...) |

Ade, Do you have the horizontal attachment for the Bridgy ? John S. |
