My first try at a laminar flow nozzle

I've been lurking on this forum for several years, intending to try my hand at a laminar flow nozzle when time premitted.  Well, recently time did permit, so I've built my first nozzle.

I used 4" diameter PVC, two feet long (that was already cut at Lowe's), and inside I have the fairly usual scrub pads and bundle of drinking straws.  My outlet is just a 1/2" hole bored in a plastic test plug with a spade bit and smoothed a little with some steel wool - certainly needs improvement.  My inlet is straight into the back, not a tangential one, so that's clearly another thing to improve.  I simply hooked it up to a 1/2" garden hose to see what might happen and the video at the link below shows the result.  I was pleasantly surprised.

I can make a tangential setup pretty easily, I think, but I'm wondering if anyone can help me get a proper "standard brass outlet" that so many of you use.

My intent is first to plumb it to my pool pump (may require a damper to smooth the flow) and then to add light.  A cutter is not high on my list right now.

I'd welcome comments, suggestions, etc.
