I have done a video on how to use the quick stick but don't have it on my site yet. May have to do some editing.
I get an old shaft and heat the back of the cube and push the shaft in to make it like a lolli pop. I then set out a doz. inserts and heat the block as I rotate it. Take the inserts one at a time and roll the bottom 1/4" or so in the glue and set them down on a piece of wood or hard plastic (something that can take the heat). When done, you can put away the glue and re heat each insert one at a time being careful not to overheat them. Twist while inserting them into the shaft to spread glue as you insert.
When the inserts are seated, I let them cool before picking off the excess glure, you you may wipe the with a rag if you prefer. you may shoot them by the time you put in a point and get to the bag.
good luck, bigjim
