Then make a slingshot contained inside a black-painted PVC gun-looking shell.


Or just fill it with pinball machine parts. I think you've gotten about as much useful information as you're going to get out of NerfHaven users about t-shirt launchers. I would advise you to look into the spud gun links that have already been posted or search elsewhere. This is obviously not a job for a nerf gun.

You could either use this or this I would probably prefer the "paintball rocket launcher," but that's just me. Good luck.

I am defiantly not using a slingshot. I'm also not going pneumatic, because I'd get pricy and we have a budget. I have a prototype hamp design im testing at the moment. If small scale works well, I'll make a full scale one.


I would be very surprised if this works well. HAMPs work despite their lack of stored energy because nerf projectiles aren't particularly energetic. Although scaling up the PT diameter would allow you to maintain the leverage ratio needed for a high exit velocity per plunger velocity, anyone who's strong enough to fire it 30 feet could probably throw it 60 feet. You lose lots of energy in leaks, friction, and most of all the stop at the end of travel.

Really, unless you're going with a giant air tank or CO2, a slingshot is your best bet. If that lacks in "cool" factor, you could compensate by making the slingshot a pseudo crossbow with a gravity feed system.

Just an update for anyone who might care. I have made a normal sized hamp with a 1 inch size PVC barrel but I used bunnies cords, so all you have to do is pull the plunger back to shoot. And I'm Shooting rolled up weighted bandanas with about 27 feet. It's quite amazing what u can do in shop class with PVC and duct tape. My shop teacher would like a trigger on it, but I'll figure that out on Friday.

You could get a snap trigger and have it work similar to the snap carbine trigger in that it is down before it is primed and once it is primed, it will catch and look like a regular snap trigger. One thing you would have to incorporate is a hole in the bottom of the hamp and one in the plunger rod (I am not sure if it has different terminology in the hamp.) You could also put a snap on handle around the hamp where the CPT is.

That's exactly what I was thinking.

Just an update- the small scale prototype

The final design will be straight, or folded in half. I hate the 90 degree barrel on this. Hard to aim.

Just a quick question. Would this still be considered a hamp, or should I designate it as something else?
