I'm not sure, but isn't the current needed proportional to the surface area of the object that you are plating?  If so, large objects would need a power supply with a much large current capacity than smaller objects.

How much we talking? I have a 1-30V 40A max power supply..

you're a bad influence :o my kits are on their way...

I have a 12v 8amp power supply with a separate current control, plating takes around 0.1amp per 25mm square area, so even large prints shouldn’t need a lot of power.

Look forward to seeing your plated parts!

@ssangster is probably correct, but Caswell has some tech support info here:

and this power supply calculator here:

Another trial finished with brass brush plating.

Didn’t come out brilliant…don’t think I cleaned the part well enough after copper electroforming.

That's what I gathered from the posted links, but it looks like the requirements are ~0.1A/in^2, which means large pieces would still have pretty low total current requirements. 

Thanks all for posting - you guys find new ways for me to spend my money every day. It's okay though, eating is for the weak.
