To anyone who wishes to help:

Is 18" too tall for the main support with the Lehman?

Has anyone used a piece of threaded rod for the boom,  or is it better to
stick with an aluminum dowel,  say 1/2" in dia. ?

Is the angle of the boom support wire, in relationship to the boom,  a
critical item,  or is it just desirable to keep it somewhere around 30
degrees?

Thanks,  and sorry for the elementary questions.
