I cut away one of the black "loops" that connect to the arm socket. I went with the left arm but don't think it matters. I then positioned that socket to be in line with the other. You can check this by inserting the arms. Now turn the "walker" on it's side. Mix up some 2-part epoxy and put just enough in the arm socket to cover the axel head. Let it dry , turn over and repeat with the other side. This will lock the sockets in place and move dr shrieks arms in unison.
Now I sure could use some help with the molding issues in my other thread. A clean copy of the dr shriek instructions would be awesome, can anyone help a guy out?
