Hello,
I have an item that could be used as a 'control wheel' that is 10" dia. . The center hole is maybe 3/4" , threaded.
I believe it may have been used to operate a flow gate for irrigation ? It is heavy cast iron, but you could prob use some of that plastic /rubber dip on it they sell at hardware stores so you don't get bit. Let me know. I can send a photo. Free, just pay shipping.

Reason being is that the turning of the combined 4 variacs while smooth, does offer significant resistance to overcome the friction of turning the rotating guts of 4 large units. I'm sure the factory 7" outer diamter control wheels that Powerstats come with are more designed for operating a single variac unit and not multiple units. (Multiple units are typically operated with a remote control motorized drive). I can run the variac thru its range simply enough, but to do so comfortably pretty much requires both hands. So, I'm kind of looking for something a bit larger, say in the 10" to 13" diameter range, or maybe just 8" diameter if it had one of those "suicide knob" type handles on the wheel, like a lathe
