Hi all. Just a couple of pics of the finished crankcase. Or how to turn an expensive lump of aluminium into a hole :scratch: cheers Roy |

Roy, said it slightly tongue in cheek - I wouldn't trust my chinese mill dials either, except for over short distances ... the further I go, the larger the error gets, must be thread pitch error or something?! I haven't got around to installing a DRO either. I've always debated whether to spenda few hundred quid doing that or putting that money towards a better machine! I think a better machine would cost an awful lot though, unless I went down the older but better quality route like I have with the lathe. Anyway, looking very good so far! :bow: |

Thanks Nick. the trouble with my mill is for a start its an imperial one, they didn't have a metric version in stock. the dials go from zero to 6o thou then a 2.5 thou gap back to zero. so you go from 0 to 60, turn the dial to 0, go to 60, turn to 0, and on and on and......................... :doh: the measurement you want is in mm so convert to thou, divide by 60 for number of turns plus remainder. by the time I've done that for a distance ( and lost count ) I may as well measure the space with a wooden rule and a piece of chalk. :bang: :bang: silly bl##dy thing. Roy who will struggle on regardless :D |
