Hi,
Well thanks that explains alot I was wondering if I was going mad with the acid figures.
I have one more question that is not really related but im waiting for my air pump for my ano tank to come but I got a bit impatient and started to have a go at anodising without it.
The problem I have found is the 720 calculator works great it tells me what constant current and voltage to set up, but when anodising I leave it untill the required time it says to do 1mil thick by the calculator but my power supply never reaches the max volts setting? and I have even run the power supply for an extra half hour and no difference,it just sits in current limit?
Can you shed any light on that for me as I would say the part is sort of anodised but im not happy as it dont seem right I can scratch of the colour easy ie its not durable at all.
Best Regards
Richard and thanks for your help
