Warhammer 40k Frag Grenades
To make a frag grenade I cut down some 1.5" diameter PVC and sliced a coupler into rings. The rings were glued to the tube with some space between then grooves were cut into them.
To cap the ends I cut circles from .08 sheet styrene. For added strength a wooden dowel was glued in the center and screwed down.
A belt clip was made from a bent strip of aluminum.
The top ring was made from an eye screw with a ring inserted. This was then screwed into the wooden dowel.
After painting the belt clip was attached with pop rivets and the top ring was screwed in. A washer was glued to the bottom around the screw so the grenade could sit upright.
Overall they aren't hard to make but cutting the rings and grooves is a bit time consuming.
