Homemade Mini Coaxial Airgun

Step 2 Putting parts together

Time to thread some of the parts together.
Make sure to add atleast 4 layers of Teflon tape to each joint before threading it in.
Take your 3/4in female adaptor(pvc) and thread your 3/4in to 1/2in bushing into it. Make sure not to overtighten here, you don't want to crack the pvc.
Next take your 1/2in to 1/4in bushing and thread it into the 3/4in to 1/2in bushing. Tighten this one as hard as you can, you don't need to worry about cracking the metal that much.
And then repeat what you did with your first female adaptor with the second female adaptor. Then with the second female adaptor thread a 1/4in nipple into the 1/2in to 1/4in bushing. Then thread a 1/4in tee to that. Thread a 1/4in nipple to one side of the tee and a schrader valve to the other side. Then thread the 1/4in ball valve to the 1/4in nipple.

And thats it for now
