: Small wooden dowels or toothpicks often act as pivot pins for the moving parts.
Most DIY rubber band launcher projects require basic workshop supplies:

Creating a rubber band launcher is a popular woodworking and craft project for hobbyists. Using a template in PDF format allows for precision when cutting the various components needed for the mechanism. These templates typically serve as a blueprint for the frame, the trigger, and the notched wheel that holds the rubber bands. Common Project Types Templates are available for various skill levels: Single-Shot Models
Remove the paper template with warm water (if using glue stick) or by sanding. Round over all sharp edges. A sharp edge will cut your rubber bands in half after five shots. Soft, rounded edges increase band life by 300%. : Small wooden dowels or toothpicks often act
: Sandpaper is essential to smooth the edges of the trigger and release mechanism to ensure the rubber bands do not snag. Working with PDF Templates
I’d recommend it with two caveats:
Instead of reloading one band at a time, modify a Gatling template to include a gravity-fed hopper. This requires cutting a vertical slot into the top barrel. (Search for "Hopper Fed PDF" on Etsy).
Drill the pivot holes for the trigger and hammer before you cut the internal slots. A wandering drill bit will ruin the trigger action. Using a template in PDF format allows for
