Thanks lads - I have to admit, I'm glad the holes are over & done with. Of all the machining I have to do to this thing, that was perhaps the most difficult bit... although I've got to measure up & make the plugs yet... so we're not totally out of the woods yet. Anyway, here's a bonus picture; I wasn't sure if the camera would do it, but - once again - the ol' Olympus just keeps on giving the goods: Yup, that's a picture of the bottom of the hole, with my test hole in it (and the camera successfully auto-focused on that, unbelievably). You can clearly see that the test hole is a little off-centre, maybe 1mm or 2mm tops. Depth of cut's not bad either, it looks like the tip of the drillbit is pretty much spot on the 483mm, that test hole should be 0.5mm short of the full length. I think I can basically pronounce myself happy with those results. Of course, whether I can convert this agricultural-sized machining success down to making tiny fiddly parts at a later date... well, that's a whole world of pain just waiting to happen I think... |

Ade, might it be worth drilling the remaining test holes (if you haven't already done them) with a small diameter drill so you can check if they are centralised, then (if near enough) open them up to full diameter or (if not quite right) adjust the table and then drill down with a slot drill of the full diameter, taking out the test hole in the process?
