It will either survive or get shoot.
I built a stand for a club chrono and it worked well , until they put the same make of chrono on the stand . It got shot with the first shot through it , no one told me the spare chrono did not have rubber feet on it
My thoughts on the clear tube was to not block out any light, if that's not an issue then yes a steel tube would be better. Maybe Ali to keep the weight down.
