I already have a very solid tripod and don't really want/need another. Thanks. Post Extras:       Agatha professor emeritus Reged: 06/04/12 Loc: Minneapolis, MN Re: Vixen Porta II head - 3/8" bolt?

Depending on the top surface of your tripod, make sure that there is plenty of bolt threads that turn into the Porta base. Also, it is always a good thing to make sure all threads are clean of any metal debris, etc. I always like to put a hint of grease on clean threads also. It spins easier and pulls tighter easier and will even help protect threads. I like at least 4 full turns of a bolt into a mount head. It simply gives more holding power and less likely to strip the threads. And if you have a spare 3/8-16 bolt just by itself, do hand thread that into the Porta first just to make sure threads are good. Best, Linda B.

[Re: Thomas Karpf]       #5616679 - 01/11/13 04:28 AM Edit   Reply   Quote Quick Reply   Tom, Oh dear. David is absolutely right. I just seemed to remember the number 3/8 being thrown around when the Porta II came out. I liked my original Porta so much I purchased another one (Porta II). I've never had it on a different tripod. So, just now at 3:30 in the morning , I went and removed the head and checked the threads. Yes indeed. Definitely 10mm. So, Tom, if possible, do change your tripod mount bolt to a 10mm X 1.5 A 3/8 will fit BUT it will be loose. The 10mm is correct and a proper fit. Sorry for the confusion. Best, Linda B.

I'm usually very particular with bolt threads, etc. I just went by what I remember hearing. I still am surprised that the Tak Teegul uses a 3/8. At least, that is how it is described. A good reason to always check. Thanks again. Best, Linda B.
