Has anyone ever tried a drywall lift for attaching/detaching himax wings?
Seems to me like a viable solution to one-person wing rigging. angle is adjustable as well as height. And on castors as well.
Sure, one person would have to make a few steps back and forth to get the spar pins lined up but far more easy to adjust as needed than a sawhorse.
Pretty cheap @ Harbor Freight      

there is an example of this on line somewhere, dig around and you will find it, guy who did it was happy with his arrangement, I thought the part that would prove problematic would be the castor wheels on grass, that is a lot different than on cement.  Persist in your internet searches and you will find it.  Another man even went to the length of a video of his arrangement, used pvc and lumber and put it all on wheels, you probably can find that one on Youtube, they may even both be on this site if you did around

Thanks kfb, I did indeed find the videos you recommended. And you're right, castors are next to useless on grass.

could change the casters for those massive castors with pneumatic tires....

Hiya Puff, Yeah that could be done. Pretty easily too actually. After your reply, I got to surfing the net and found some pneumatic castors that would be easy to modify. Thank you.
