Welcome to WaGuns, CarlMc!
Great instructions, thank you.
My targets are similar to what you describe except I use larger pipe (2", I think?) so the furring strips can just drop into the vertical pipe. My vertical pipes are longer (same length as the lower pipes), so the target still stays upright. I also cut mine in shorter lengths; if I remember offhand, they're more like 13" each.
I carry two targets in a duffel bag, though I've started trying to keep the base partly assembled. I might add some glue at some point so that the stand will be only six pieces, which I think will be a good compromise:
- Each horizontal end pipe plus two elbows, glued together
- Each horizontal side section, consisting of two pipes with a tee in the middle, glued together
- Each vertical pipe
