This post will be of interest to a pretty small audience. However, if you own an Avenger A660 or A665, here's an easy way to add to its utility:
A nice feature of the Avenger A660 lightstand is that its fold out castered legs sit perfectly parallel to the floor when deployed. That's nice because, if you have the need and are so inclined, you can easily fabricate a neat little platform that sits on these legs and can support, for example, an Elinchrom Ranger or other battery pack/flash generator. With the pack on the platform, the stand and light become truly mobile.
This is what the base of an A660 looks like close up:
As the annotation says, a standard piece of 1x2 lumber will fit perfectly along the legs and between the arms of the central casting. Like so:
Two 9-1/2" pieces of 1x2 and an appropriately shaped piece of plywood can be assembled into this:
And the topside with adhesive-backed cork sheet appied:
The platform can now be seated on the legs like so:
And it's ready to do its job:
The whole enchilada (the enchilada being the A660, platform, D570 extension arm with swivel pin, counterweight, D200 grip head, Westcott shoot-through umbrella, and 600WS battery powered flash with ringlight head):
(Sorry about the quality of the last photo. We made an ISO 1600 faux pas).
Now if a Ranger ever enters my life, it'll have a place to sit.
