jet test 1
with no template this is not exact but lets me know it works
i drilled 2mm holes into the acrylic and superglued 2mm brass tubes into each hole.
then cut all the tubes to the same length and made sure there was nothing blocking them.
after cutting a chamber into the top and also making a little funnel shape at the top of each hole you can see it works very well
next to make a template and make sure it's spaced correctly.
i need to do some practice runs drilling the holes close together into a copper base.
