Johnny - if imitation is the ultimate compliment, then I guess you get some accolades today!
I did find my end caps, but 2" so I didn't pitch what I thought I had. These are 3" PVC @ 14" long, and 1" coupler holders @ 3".
I was eager enough to do it, that I cut it all with my NEW 80T trim blade on my NEW miter saw!
I'm not using caps yet, but want to put my suction pump in one of them, and figuring out a way to make it so it doesn't fall through, since no handle. Might just wrap it with copper ground wire, and make a hook.....
Too friggin' hot and humid out there to do anymore just yet...
