I finally got it all together and did one. The discussion started in this thread: http://castboolits.gunloads.com/show...hlight=anodize
For those of you who were interested, here's a pic of the results. It came out a bit dark but is quite nice. The oxide layer didn't amount to much, it looks like this mould will be about a half-thousandth smaller by the parting line and about the same perpendicular to it. I did dress the alignment "Vee" notches and the faces slightly beforehand in anticipation of the added thickness "Beagling" the mould slightly, which it did.
When I get it put back together and get a chance to cast with it I'll give a full report.
