I'd love to see what everyone uses for their min-diameter rocket launch towers (or towers for whatever rocket you happen to use them for). I have a few min-diameter rockets now and I'm getting going on tower designs. I have my first design done & assembly is almost complete. I've seen mostly old tiny little grainy pictures of towers here & a few other places online. It seems people use all kinds of structures: plywood, 2020 rails, T extrusions & more. I'm planning on designing & welding an adjustable all metal tower, but I haven't started on that project yet. For now, my v1.0 tower is fixed for 29mm rockets & it uses EMT conduit, some L extrusion and 3d printed end supports that slide onto a 2020 rail. The 3d printed parts are nearly solid & have metal bolts embedded as strengthening supports for the EMT conduit. I did a test fit of all the pieces tonight, but everything isn't pushed all the way together yet. Here are some photos of my tower - let's see yours!
