Gorilla glue and grabber screws. This usually takes about 5 minutes and costs about $1.50. Do it today and mount it tomorrow. I do the Mikey P. method if I turn the head or something. I do the G.Roof method If I am out of Gorilla glue. You can have it done in less time than it takes to go to the store and buy the gorilla glue. There have got to be a million ways to do this. PS. That mannikin should have been cut at an angle and not straight across.
