LOL, you kill me man. Why dont you tell me how I should throw a pointy steel weight up above my head for laughs, then spew some more hate everywhere you can about our products. You sound like a crazy person.

The APTA uses recognized NPT threading with scheduled aluminum and NPT fittings. Its what you call engineered.

You got it all wrong @bonner1040 . I don't hate any one.
The military had a death with a pneumatic launcher in regular duty.
What are the cycles to failure with the Apta. when should it be retired? Destruction testing?
Can you tell us anything quantitative.
My guess is you don't give a shit based on your significantly lacking and unscientific response.
Regarding the pointy steel weight, it works very well for many. I don,t sell throw bags to jam up or jam into an Launcher
a well engineered throw weight coupled with well engineered launcher is what is needed.
My guess is this is why TS sold to ST. When the shit hits the fan or explodes it will be the lawyers and corporate america to deal with the fall out at the expense of the worker/casualty.

What are cycles to failures on an air compressor, bicycle pump, 2x4 or truck tire? You can use all the buzz words you want and make veiled references to a military tool exploding but that doesn't mean anything.

The APTA is perfectly safe and the operating pressure is well below the SWLs set by the manufacturers of the standardized components that make it up.

I've been using lawn darts as throwweights anyway. Way cheaper than the rope knight, does the same thing too.

I have the APTA and have faith in it. I filled mine with aprox. 120psi. I left it in the back seat of my truck over night. Mid day I shot my 12oz bag straight up along side a Black Locust to judge the height. It easily hit 80'. There was no loss in pressure. I have knowledge of mechanical nature as I turned wrenches on cars and trucks in my 1st trade. I feel safe using this tool. I'm not knocking the crossbow method. I like it. I see advantages of each. If a line was to break I'd rather have a run away bag than a run away bolt. That could cause a huge problem ..... just sayin' :D

Lawn Darts ..... I remember those ...... briefly. Us kids were banned from touching them. We used to throw them straight up as high as we could, then we'd play chicken.:D
 
Show me a lawn dart that can do what a RopeKnight can and I'll buy your APTA and sing it's praises for years, in the same way I Had done for years for TreeStuff before you started.

The APTA is not considered a firearm or a destructive device and is protected by specific language in the Title 5 code. It is legal in all 50 states.

Are you aware of local regulations barring dedicated pneumatic line setting devices?? I am not.

I am not, either. I was just thinking that some things, like potato guns, for instance, were prohibited in certain places. I thought I also remembered reading about someone that had his spud gun confiscated by the police. But I think he might have been a younger kid, and not using it for line setting. I guess it would just be nice to be able to quote chapter and verse of the law that allows its use, for the time when the cops do show up wanting to take it away. When nervous people call the police, the police respond, and that is when you have your street trial. You have to be able to defend yourself well in this instance. Property seizure is different than a criminal charge, I think. You have to prove yourself innocent, or they can take it away, I think.

I am ignorant about the Title 5 Code. Could you tell us more about that, please? By the way, I am not a hater. I own the APTA and love how well it works. I just want to be able to keep it. Thanks in advance for any answers you choose to give.

Tim, the legal system does not like giving a simple and easy to understand answer to anything. That would put too many lawyers out of work.

Much about legality has to do with use, or more accurately, misuse. For instance, a baseball bat is not illegal unless being used as a weapon. A nail gun can be very dangerous yet is used legally all the time in residential areas.

If you are not shooting beer cans off the neighbor's fence or hunting squirrels with your APTA and are using it as intended, for setting lines in trees, there should be no legal confrontations.

Lawn Darts?

@Mastermind

Maybe he knows a Possible source for replacement parts.

What is the max operating pressure?


Rock On Bonner.

Basically it says that if you use something as a destructive device it is a destructive device. It also has clear definitions on muzzle diamaeter, propellant type (combustion vs air) , and manufacturer intent that classify the APTA as a Line Setting Device.

Potato guns, usually driven by an explosion are considered guns almost everywhere and are rarely built correctly or used legally.
 
lawn darts and Aptas in a crossbow thread? Cool!!!

If any of youse are visiting Montreal, be aware that they have a bylaw, and saying you are carrying a machete to go harvest some sugarcane ain't gonna help you.
  1. "No person carrying or having in his possession a knife, sword, machete or other similar weapon, without a reasonable excuse, may be in a public place, street, park, public square, on foot or in a transit vehicle.
    For the purposes of this article, self-defence does not constitute a reasonable excuse.

  2. Any person who contravenes this by-law is guilty of an offence and is liable: (1) for a first offence, to a fine of $150 to $300; (2) for a second offence, to a fine of $300 to $500; (3) for a subsequent offence, to a fine of $500 to $1000."

I'm not sure that's correct - the ATF in the US certainly doesn't. They've written several letters to this effect:

The Bureau has previously examined devices known as 'Spud Guns, Potato Guns, or Spudzookas' and have determined that such devices, in and of themselves, are not firearms ... However, any similar devices which can be determined to be weapons by reason of their design construction, intended use, actual use, ammunition or other factors may meet the definition of a firearm

26 U.S. Code § 5845 explicitly mentions line throwing devices:

The term “destructive device” shall not include any device which is neither designed nor redesigned for use as a weapon; any device, although originally designed for use as a weapon, which is redesigned for use as a signaling, pyrotechnic, line throwing, safety, or similar device

Some states and municipalities may ban launchers based on the flammability of the propellant, but most don't. Most people reading this can legally use Aquanet and a sketchy PVC launcher to get a throwline into a tree if it suits them.

I'm a bit disappointed by the tone of most of this thread. The 'Buzz is usually pretty chill about acknowledging that there are many ways to do things, and that different things work for different people.* There are a lot of other forums where you can find all sorts of attitude about The Right Way to do things, I don't think many people look for that here.

* (I use a DIY pneumatic launcher made out of 1" galvanized pipe, with an elastic-actuated ball valve. It weighs like 50 pounds too many, requires custom throw-bags, and its power is on the verge of being underwhelming. But - it was cheap, and works for me! )
