Tell me this isn't sexy:
Several weeks ago I saw one of these Speedotron 22" reflectors on display at B&H. What caught my eye was the fact that the Speedotron mount was fastened to the dish with four small bolts. The mount itself looked like any other flanged speedring component with the exception of having four holes drilled in its periphery.
So, to adapt the dish to the Elinchrom mount:
1. Remove the 4 bolts (plus washers, lockwashers, and nuts) to release the Speedotron mount.
2. Get youself a suitable Elinchrom-compatible ring (in my case, I used the Norman ring I had on hand).
3. Clamp the Speedotron and the new ring together flange-to-flange like so:
4. Using the existing holes in the Speedotron ring as a guide, drill 4 holes in the Elinchrom ring:
5. The hard part is now done! Bolt your newly perforated Elinchrom mount to the back of the Speedotron dish:
6. Done! Now mount it to the light and admire your handiwork:
Some other views:
So, that's it. The Speedotron dish is $124 at B&H and a Norman Elinchrom-compatible ring is about $19. Resist the urge to get the $10 SP ring; its diameter is too small for this application.
And before anyone asks, yes, the Calumet modeling light most definitely is a problem (again).
