Hi ROyce.
Don't know yet. I am still trying to find a regulator that I can use
for this and don't have time for the "Search" yet. I am hoping this
weekend I will get some time to finish it up.
I did notice though an interesting thing (I am only using water at the
moment). There does seem to be a bias as to how the water flows and
circulates in the tank.
For example, if there are more bubbles on the left side, the flow of
water is in a circular, clockwise rotation. This draws the bubbles
from the right bottom and pulls them towards the left side as they
rise up. What I am not sure of is if the bubbles actually do
the "Scrubbing" or is the "Scubbing" simply a function of the flow of
etchant.
If the bubbles are doing something, I will be getting some uneven
etching. I am going to try and modify the baffle a bit so that the
flow is back to front as opposed to left to right. I believe this
would even out the etching.
