I think it is probably harder to get a consistent plating with the brush and have considered going over to tank plating, I just need more space for it. Yes I have also done etching after your tutorial and have great plans for that. It's a shame your site isn't up any more it was a great resource all in one place.
I have had some serious pieces of titanium sitting around for ages to make into pens and I want to anodise them, but need to get a better power supply.
