Hi,


It doesn't spray very well and i don't know why ;-(

What do you think, how can i go about making it work well?

I can spin the tube at 10000RPM+ without any fear of things flying apart.
It is hard to see where the drops impact, but it doesn't look like it is
enough.

How can i better see where the water is spraying and in which amounts?
I am reluctant to fill it with etchant and try, because a change to the
sprayer tube with etchant in it requires a careful cleaning each time i
want to make any changes.
