How to Install the Asguard APD. First, remember that these are meant only for 1/4-inch diameter solid fiberglass rod.  If your APDs are for crossbow bolts, you probably need to remove the built in nocks.  Simply cut the tines off with a pair of sharp scissors or a sharp knife.  If your APDs are for arrows, be careful not to damage the tines of the nocks when you push the APD onto the shaft.  I do this by using the edge of a chair.  Place the large round hole of the APD on the chair with the tines off the edge of the chair.  The fiberglass shaft will be vertical. Lightly sand the end of your fiberglass shaft with sandpaper or a file.  Be careful of the fiberglass dust.  It will make your skin itch and burn.  Now, make sure the shaft is clean and dry of dirt or fiberglass dust.  Wipe the shafts with acetone (not nail polish remover) and a paper towel.  For the absolute best results, rough up the inside of the hole of the APD where the shaft is inserted.  A wire bore brush works great for this.  I use only GOOP brand adhesives.  They work the best of all I have tested.  A tube costs about 4 bucks and will be enough to glue a couple hundred APDs.  I use mostly Plumbers GOOP in the purple tube as it is the easiest to find. Put a generous blob of glue over the shaft hole of the APD.  Push the APD onto the shaft until it touches the bottom of the hole and the glue oozes or spurts out of the APD hole.  Push hard. Push the shaft in with a twisting motion to distribute the glue evenly.  OK, one more time!  Pull the shaft out and repeat the procedure. The Asgard APDs usually fit the 1/4-inch shafts very snugly.  So snugly, that the shaft will push all the glue down to the bottom of the shaft hole. You must push the shaft in hard enough to get the glue to distribute between the shaft and the APD.  You must also twist the shaft. If the glue creates a bulge at the bottom of the shaft, you can poke a small hole in the bulge with a thumbtack.  This is a lot of fun because the glue will spurt out suddenly and make a mess.  So cover up that nice dining room table you are working on.  Set the freshly glued APD and shaft aside for a minute, then push it on again to make sure it is not being slowly pushed off by an air bubble in the bottom.  If it is being pushed off, try the thumbtack pinprick trick previously described.  Watch for spurting glue as you push the APD on again.  Getting GOOP adhesive out of carpeting is icky. Let it set for 7 days, without moving it.  I am not exaggerating!  7 days!  I have had APDs ready in 2 days, but not always.  Do yourself a favor and learn from my experience.  It’s no fun to have a marshal fail one APD after another after another… Test the APD to make sure it is secure before shooting it.  Test it by grasping it and trying to pull it off.  It you can pull it off, or twist it around the shaft, re-glue it.
