As an aside, I have seen websites which deal with home-brewed anodizing; although they deal with mostly small items (camera and telescope fittings), perhaps the techniques can be scaled up. One hint: When working by hand with whatever abrasive you chose, either run the abrasive off the end of the workpiece or lift it as you near the end of your stroke. Starting and stopping your stroke along the length of a workpiece will result in a brushed patina which has a lot of "J" patterns instead of lines which are consistent. Any unwanted patterns are hard to remove without stepping back to an abrasive coarser than the one which established them. Please make sure to note that Alistair said "RANDOM orbital sander". I've seen ORBITAL sanders RUIN many a beautiful thing. George |
