Jack, I'd be embarrassed to admit to how many experiments I have performed in illumination and diffusion. I came to the same point that you have arrived at which is experimenting with studio strobes for the same reasons.

I used 160-watt strobes and they worked pretty well, except that they were inexpensive with no cooling fan. Making a short story shorter...they pooped out on me and that was the end of them. I believe that if you can find ones that are fan cooled and rated for high usage they should perform the way that you would hope.

My thought on vibration is that it becomes an issue when either the camera or the subject moves independently of the other. When they are moving in unison, the centerline between them does not change which is why I am a proponent of mounting the subject and the camera on the same sub straight.

Thanks for those thoughts and suggestions Sippyjug. I think your're right about having everything moving together. I thought I had it solved with the heavy tripod and geared head but I'm not that confident about the geared head being absolutely stable. I think my large (55mm) ball head will be rock solid once tightened and I can use the threaded legs on the Platypod for aiming the lens. If it works, I'll probably stay with my LED lights.

the A/B strobes on 1/32 power should hold up pretty well and at that power they will have to be diffused quite a bit At the aperture you are using.
Paul C Buff has always had a great warranty and Customer service.


Thanks Frank, I will keep Alien Bee in mind if I go that route.

Would you be willing to try one of your A/Bs at 1/32 power for 150 flashes at minimum recycle time, and tell us if it survives?

Actually I responded to the OP,

So in a word NO. My strobes are old and I have nothing to gain.

Yikes, that's quite a rig. Thanks, Dik, for sending the pic.

Up to now, I've been using a heavy tripod (Bogen 3033 with geared head) to hold the WeMacro, next to a heavy metal desk holding the subject, both resting on my concrete basement floor. Today I'm doing some tests using a Platypod type plate with a heavy ballhead to hold the WeMacro, with both it and the subject on the metal table. I hope to see one or more stacking worms to see how straight the movement is. I plan to take at least 100 pics at 5 micron increments for each test.

Just a question: Do you have any safety cables in case one of the bungy cords were to break?

No, the bungies are very strong. Very lightly loaded for their capacity.

your gear!!
I wouldn't trust my gear on a bunch of rubber bands without some backup.

The external framework on which the bungees hang, has cross bars just a few inches below the camera rig. Even if all bungees let go, the rig would only drop those few inches.

The camera is MUCH safer in this rig than in any tripod or handheld use.

Now if you want to talk about gear at risk, look at my BIF Boom Gimbal Chair Tripod in my profile picture. Many points of potential failure that would cause huge equipment damage and personal injury. But I think I built it strong enough.

You are right about the being on a tripod, and the setup is quite innovative for beating vibration, I just don't trust any bungy cords!!
I don't have any trouble with vibration in my area other than a sonic boom once or twice a year so my setup sitting on concrete is great (for my work).
