Ok guys, I've been a lurker around here for quite a while, figured this was a good time to start posting. I just made up a couple of these with some older GHG Great Buy Mallards and figured I show them off.
First off, I got the weasel balls from here: http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 1107753459
The seller will combine shipping. 5 of them shipped cost me $19.
Now after weighing my options on how to mount this I opted for attaching the ball to the underside of the flap I cut in the decoy with a screw, straight through the back of the deke into the side of the ball with the motor attached assuming that the higher I make the center of gravity the more motion. I cut the hole in the back just large enough for the ball to fit in but made the cuts go all the way to the neck of the decoy so the flap lifts easily for turning on/off, changing batteries, etc... When you cut the flap the decoy deforms just a little bit so you can push the flap down inside the body and it stays closed, when you want to open it just push down on the tail a little and the flap pops right open.
I put the screw right through the the mark on the ball left from being molded which brings the screw through right next to the attachment point of the motor. I also painted over the head of the screw with black and gave it a coat of the same krylon flat clear I use on the decoys to protect paint.
I only posted pictures of the hen but I did both a hen and a drake (with the great buy mallards the two are differently shaped and move a bit different). Here is a video of the first test run in the bath tub:http://www.youtube.com/watch?v=SCKgApe5 ... ontext-chv
