No probs. Thanks for that cooling info. Earth wires are green with abit of yellow over this way. I've got the dimmer wired in and it seams fine but I have anodised for 90 mins at 4.5A/sqft and the colour is taking well but is not deep enough even after being in the colour bath for 45 mins.
My previous experiences make me think that this is a result of the anoditic layer being too thin - anodising at higher current densities gave much deeper colours so my natural reaction would be to increase the current density but this would seam to contradict your advice as it would create smaller pores. What would you recommend?
The only other thing I can think is I am using the same concentration of acid as for the previous anodising system and maybe its be erroding the layer - The acid currently has an S.G. of 1.100 (I know you don't really think S.G. is important but I have changed the acid concentration so many times fine tuning it for the previous system that it is the only rough measurement I have of the acid concentration).
Other parameters are: acid temp 57deg. F. Voltage 8.6v
