In this Tutorial we are creating a 16mm conduit breech for a 20mm conduit coupler. You may just use 16mm conduit inside 20mm conduit for a breech, but the seal created by the 16mm and 20mm alone is not great. You can use PETG with Electrical tape inside 20mm conduit as a alternative. However I have found in my experimentations that 16mm conduit is a better barrel material than PETG for my blaster I am using.
Materials (You can change materials around):
- 16mm Electrical Conduit
- 20mm Electrical Conduit
- 15mm PVC Pipe
- Electrical Tape
- Hot glue and Gun
- Heat Gun
- Pipe Cutters
Firstly cut a piece of 16mm and 20mm conduit the same size, approximately 5cm. This is so the breech can be attached using a 20mm conduit coupler. You may be using a different coupler, so please substitute materials to comply with this.
Using a heat gun, heat up a end of 15mm PVC pipe and slip the 20mm conduit (you cut previously) inside the 15mm PVC around half way. Now drill a hole through the 15mm PVC, 20mm Conduit and 16mm conduit and insert a screw. This will act as a dart stopper. Remember to hot glue and seal of any gaps, like the nail and around the 15mm PVC edge.
Measure and mark of where you would like the breech opening using a nerf clip. *See Picture Below*
Now cut the opening using a dremel or saw. Be careful.
Now cut a desired length of 16mm conduit (this is the barrel). Also cut the 15mm PVC to match the 16mm conduit barrel.
Cut around 10cm off the 15mm PVC, you may cut more or less to suit the size of your hand (this will act as the handle). Now attach the 16mm conduit barrel inside the 10cm length of 15mm PVC by E-taping the 16mm conduit. Hot glue the edges of the 16mm conduit and 15mm PVC.
Lastly, E-tape the other end of the 16mm conduit to create the seal. Make sure the seal is not too tight and not too loose but 100% air tight. Now lube the seal and inside the 15mm PVC.
Remember you can use any other materials to substitute any materials. eg. PETG and 20mm Conduit sliding Breech
