Concealed "Caddyshacker" Pneumatic (Design Posted)

Unread postAuthor: Not_Again » Sun Sep 14, 2008 9:02 pm

This might be a little farfetched, but with some time do you think it is within reason to try and develop a compact golf ball gun which:

1. Scare the poopers out of nearby golfers.
2. Haul a golfball atleast 250 yards.

AND!

3. Fit in a golf bag?

I think it would be pretty awesome.

And I realize that if I wanted to keep the noise down there would have to be limits on dimensions and other aspects..

Edit:

I am not exactly the spud king, I only have two guns :(.

It has been done except I think it was pneumatic.

i think that's a good way to get kicked out of a golf course. and yes you can go it, it would be very very easy.

I will try to upload some design options within the next days...

I am thinking 3" chamber @ 24" with the golf ball barrel poking noticeably out of the bag (I will just put a head cover on it).

Inline design probably.

I just suck at electronics. I know there are a whole bunch of tutorials on solenoid valves but it would be amazing if this were remote :D

Edit:
If I can develop an easy way to have multiple charges on hand without CO2 I would be fine with pneumatic.

And what about a hop up?

It would add mad backspin on landing if I am correct(?).

Well i'll just break a few things down for you...

1) You'll need regulated CO2 or a hand pump. Reg'd CO2 will set you back about $100 if you don't already have the equipment. And a hand or floor pump will be cheap, but you'll have to pump the gun up everytime which will seem very suspicious.

2) Do not use it to try and 'land a golfball near golfers' or to scare them, that's illegal and very dangerous.

3) A 3" chamber is way overkill. A simple 2" chamber 24" long will be more then enough to send a golfball 250yards with the right valve.

4) Inline, makes the gun less compact. If you use an 'over under' design, you can have a longer barrel, better valve etc.

5) Valve, i'd go for a 3/4" QEV minimum, possibly even a piston valve. Hell you could use a co-axial piston configuration with 300-350 yard performance.

A 3" chamber that doesn't extend out the bag and a 1.5" barrel that doesn't extend too far out will suffice. You should be able to get like a 3' or 4' barrel inside a bag with a little coming out the top.

6) Trigger, I'd go pneumatic for the performance increase and ease.

I think I am sold on Pneumatic now, so if a mod finds this post, I can rename it when/if they move it to pneumatic discussion.

On Mr. Crowley's part, thanks a lot.
I am trying to grasp some sort of an interchangeable tank option, for three or so shots, that should be suffice, you think?

For shooting people, thats a no, I would just want to test out my accuracy and have a great time with friends.

This was the valve I had my thoughts on, pretty basic.

I was thinking http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100098062&N=10000003+90457+501170

I think I would go with a blowgun and then a schrader valve for airing up.

I have an awesome design in mind and if I can I will scan it up tomorrow. I find it intriguing and unique, hopefully it hasn't been done yet :D.

Again, thanks to the community for helping me out with this one.

lol, that would be cool if there was a tube to the club (hallowed) with a fake head so the end has a hole, so the club is the barrel, would be a fat club though..

What?!?! PVC clubs arn't allowed?!?!

i can imagine that :wink:

Here is the design I drew up today (pending as it is currently as PDF)

The only design flaw I think I might run into is deals with the overlapping PVC. If you look towards the front of the barrel, there is a chamber that surrounds the barrel. I am not positive but wanted to give this a shot. I would use reduce bushing, and spindle sand the stop in the bushing.

The only thing that scares me at this point is the strength of that joint when glued, as I can only get the outside of the barrel to have the glue on it.

And if a mod stops by on this post, please move it to Pneumatics. Thanks for the help.
