Frage von Frank B.:
I ask for help with an amateur stand Question: 
 I have never worked with professional tripods and have now the opportunity to acquire a possibly favorable. This tripod has a 100 mm bowl and a device for it. The head, which I will install it but do not turn half shell, but only one thread of 3 / 8 or 1 / 4 inch. 
 How can you adapt a thing? 
 Frank
 Antwort von  Charlinsky:

You need a leveling ball of 100mm, this takes the form of a half shell and a 'pen' with screw turn. In this bowl you can draufschrauben your head then.
