Bowens Mount Lug Position

Jerry: I'm fairly sure that the answer is no, it's not at 12 0'clock. I can't access my units at the moment but I'll get a definite reply first thing in the morning (or, as you would call it, allowing for the time difference - the middle of the night).
Is this any good to you or too slow?

That would be great! I appreciate the help.
I am mounting the bowens mount to my 45 inch beauty reflector for a customer and since the flash head mounts to the bracket I need to make sure that this insert is in the right position. if I remember right it's slightly towards 1 o'clock but I cannot seem to find my notes.

First thing in the morning then. I'd worked out why you needed to know and obviously that's why it's important - the customer is King. I just didn't know your time-frame.

Never mind the notes, I'll strip a genuine Bowens flash down a little bit and work it out that way. I wonder if your notes are in that same special 'safe place' where I keep putting things - then can't find again for months!

I have Bowens GM500Rs and GM250'Rs.
Sorry packed in car for early shoot, almost certain not at 12.00 will check tomorrow on shoot Sorry no internet access there on location.
Will confirm tomorrow.

The lugs are 180 degrees from what you are showing for mounting on Calumet / Bowens! Hope this helps!

Hi, Jerry! Unfortunately, the answer is "it depends". On a genuine Bowens flash, the three lug openings in the mount are located a 2, 6, and 10 o'clock positions:

Thanks Dave for taking the time to explain.
I was waiting on a response/image from the customers when I posted.
Here is the image of the customers flash (Genuine Bowens) Looks like I need to line up one of the lugs up at the 6 o'clock position for this unit. Great to know they are not standard to all flashes with a Bowens mount. It will save me making a mistake in the future if I do not verify with a image and brand.

Jerry: As is always the way in this wonderful world - things aren't as straightforward as they appear. Here's an older version of genuine Bowens flash unit with Photoflex spreedring installed. Guess what - the bloomin' thing apparently turns the opposite way on the newer model shown in previous posts. Oh deep joy!

With so many variations on mount orientation, it would certainly make things easier if the Bowens (or any other) insert position were infinitely adjustable as it would be when installed in a conventional speed ring. However, I suppose that would require new molds for Jerry's 45" dish so not a particularly "constructive" suggestion at this point.

Using a compression ring, like the bigger Mola dishes do, might work assuming the mounting area is large enough to accomodate a compression ring.

Thanks guys.
I should have just waited for the customers image.

on my Strobies mounts which use the bowen mount the lug is at 12 oclock so I guess if one lug is at 6 ir 12 you would be safe.

I typically mount my Bowens accessories using a 24 hour clock, not 12 hour one. This methodology gives me and additional 12 hours to rectify attachment issues.

This extra 12 hours is typically sufficient, but a few times even 12 hours was not enough. In those cases and I had to quickly fly away hoping to reach the international dateline (netting an additional 24 hours).

So far, getting that extra 12 hours by using a 24 hours clock and additional 24 hours afforded by chasing the international dateline has provided sufficient relief to solve all Bowens modifier connection issues.

Enjoy! Lon
