Thanks Skatol,
That seems to be the consensus from a couple others close to home. I'm thrilled with the quick change aspect now that a tedious two days of work is over. Have added screw clamps to three recepticals so branches stay in place and removed the excess hight of the vertical tube. My projects take form based on scrap I have (nothing purchased) and my welding experience, but I'm sure the same idea could be accomplished by a handiman another way. Sure has made me more enthusiastic - all thanks to CR folk! 
Here's one of the side props and a shot of the clamp.

Sweet stuff, man! I love those little branch holders. That welding skill of yours is incredibly handy!
One recommendation...try creating some of those holders such that you can hold branches parallel to the ground. Well, not exactly parallel...pointed upwards by a small angle, maybe 10-20°. The general idea with setups is that you create the perch the birds will rest on, then you surround that one perch with more stuff to create an interesting depth of field.
Lets take a pine branch with multiple fronds, held maybe 12° above parallel to the ground, a few feet up. You then either place that maybe 10-15 feet or so in front of actual pine trees for a nice blurry pine-green backdrop, or if you don't have that option, then you could use your vertical branch holders and a bunch more pine branches to create that backdrop. Array them out in a cone behind your branch, at a great enough distance to appropriately blur into creamy pine-green boke...and there you have it. Perfect chickadee perch!
Oh, and the real trick is to get the Chickadees to land just on your perch. There are a few things you need to do in order to encourage that. First, close off or take indoors ALL your other feeders. Then, set up some small open tray feeders a foot or so below your horizontal branch(es). You might want to set out a few feeders with different types of seed underneath multiple branches of differing kinds with different background setups to attract a wider variety of birds to a greater variety of perch setups. Since you have these small trays, preferably with covers that have a small hole cut into them that would effectively only allow one bird at a time to find and pull out a seed...you force the birds to queue up on the branches, waiting their turn. THOSE are your moments, when the birds are all queued up.
(It is actually quite amazing, birds are EXCELLENT at waiting patiently for their turn and sharing! Of course, every so often a squabble erupts, but then they go right back to patiently waiting on your setup branches until they have their turn at the feeder trays.
