Great stuff, thanks for the help. :thumbup: |

Interresting specs. They say international, yet I don't see a spec for 6061 plate. I've attached a pic of the 1/4" plate I have. It's just for point of interest. Bernd |

Bernd - I believe 6061 is an ISO designation; but 6063 - I was told when I spoke to Mersey Metals last - supercedes 6062 which, in turn, superceded 6061. I presume the formulations are very subtly different, but I can't tell for sure. If you want, I can ask a specific question or two of them on Monday, when I go to pick up a bit of steel I've ordered. |

Good grief, what's up with you lot .. :scratch: Took me about 30 secs. to find this ... not that I have any real interest .. http://aluminium.matter.org.uk/aluselect/05_fabrication_browse.asp I've selected the stuff I have on the LH column. sez 6082T6 is 'good' for machinability .. Dave BC |

Managed to get a few hours in the workshop today. Spent 2 hrs figuring out how to mill a radius using the dro, then realised I wasnt taking into account the dia of the tool DOH! Had one misshap, fortunately, no damage to the mill or tool, just some dints on the work piece oh and I escaped injury! What happened, got my climb milling and conventional milling mixed up. Ripped the brass out of the vice and sent it across the workshop - lesson learnt! ( it was only a 0.2mm cut as well!) Anyway, the pics show some brass hacked out of a length of round bar, first into rectangular blocks, and then into 2 croosheads - only 2 more to make now :thumbup: |
