I keep an eye on the steel scrap dumpster at work and one day I spied a sign holder that was destined to be scrapped. One look at it and it was obvious what it could be used it for. (don't you agree?)
I cut the 1/2" pipe off that held the sign, rethreaded the end and screwed a 1/2" floor flange onto the stub. The deflector was again made out of stainless steel scrap and bolted to the flange. Two holes drilled in the pipe were threaded to 1/4x20 and bolts screwed into the pipe holds up to 1/2" launch rods dropped into the pipe. The steel is 3/16".
If a person had a welder it would be easy to fab. It is bulky but makes a great launch pad.
