I also used 1/2" EMT but since I am only using 1/2 of a flexstrip per leg I cut them off at about 7.5 ft Painted mine with rustoleum green paint and then smashed one end in a vice. Drilled a hole in the smashed end and am hanging them on cup hooks screwed into my tree topper that I made a couple of years ago. Seems to work ok. I was trying to figure out the best way to close up the bottom of the pipe so now I will pick up some dowel and try that out. The place I will put the tree outside will not be flat so I have to find a way to hold the flare at the bottom. It is great fun having it set up in my screen room and playing with nutcracker effects live. The only thing I haven't been able to do so far is to get my ED talking via the wireless connection.
for the bottom of my tree i bent 3/4" emt into a half circle. i will drive 1/2" rebar into the ground and clamp the 20' long half circle a few inches above the ground. I then will use my bungee cord around this 1/2 circle on one end and the eye hooks that are in the dowels in the ends of my emt. since my tree is 18' off the ground , but the sides are 14', i have a few feet of bungee to provide the connection. it handles any variations on the ground.
glad the nutcracker effects are working for you.
why dont you try a project? Like christmas sarajevo (Only has 21 phrases). Just select effects you currently have , use the same one multiple times if you like. select an output vixen,lor,hls r lsp.
press button and see what it does. really starting to work well.
