Golf ball launcher

Unread postAuthor: Sohail_L » Mon Jun 04, 2018 10:57 am

I’m building an air powered golf ball launcher. My barrel is 2inches and it’s too big so the air escapes around the golf ball. I can’t find the right size pipe. Is there any way I can work with what I have? I was thinking about glueing Bristol board around the inside of the barrel.

Sdr21 pvc pipe has an ID that's perfect for golf balls. I had to call around a few hardware stores to find one that carries it however (Canada). As mentioned, sabots are good but take time to make. I usually use Styrofoam cut with a hole saw that matches my barrel ID or simply rags stuffed around the projectile

1.5" EMT Electrical Conduit Pipe usually fits a golf ball pretty well. You'll need to make an adapter of some form for it to work though.

European 50mm PN16 PVC pipe has an inner diameter of 42.6mm while a golfball has a diameter of 42.67mm. A nice snug fit

I fold a double layer of T-shirt material over the front of the golf balls. Works well with the 44mm internal diameter of my barrel. :lol:

That's pretty nice damage!
Could you share the design of your launcher?

Another good barrel is 1.5" sch 10 pipe. ID = 1.682"

It's pricey, but it's absolutely perfect.

That would make a good barrel, lite weight for easy aiming.

Related to tubing for barrels, when looking into this myself I found these which would be great for those that don’t have access to welding. I had contacted them And was told the pressure rating is 1500 psi so would be suitable for even higher mix hybrids.

that link took me to a 1/4: " flare...

I made a barrel by sleeving 2-1/2 with 2" I cut a piece out of. It worked great but I do not encourage anyone to ever build one. It was way to much work. I probably meesed up the pressure rating of the sleeve too.

Huh, link works for me. Picture looks kinda like a general one of a smaller fitting but they have them in both 1-1/2” and 2” sizes as well as the typical smaller sizes. They’re compression type fittings.
