Step 1: Get the stuff
5' of 1/2" schedule 40 (cheap stuff) PVC
2 1/2" PVC 45 degree bends
5' of 1/16" steel wire
2 #8 fender washers
2 sheet metal screws or similar wood screws
2 screw-on rubber bumpers or hammer-in plastic feet for stools (1/2" to 3/4" diameter)
1 48" wooden dowel 1/4" or 5/16" diameter
1. The rubber bumpers are heavier and make higher performance arrows. For tots you might use the lighter plastic feet.
2. To cut the wire use diagonal cutting wire clippers like the kind built into needle nose pliers . Anything else will leave undesirable sharp frayed ends. (Remind the hardware store employee who cuts your length of wire.)
3. If the rubber bumpers come with fat stubby screws, you will want to replace them with longer thinner wood screws (see picture).
