    3D printed throw weights

    What did you before? The typical fabric bag? What weighs do you prefer using? I’m modifying my design for the most common weights and resilience. Cheers

    My rope launcher (pneumatic)

    Thanks. I appreciate your feedback! If you ever want to build one yourself give me a shout. It was a fun project. It was no great savings in money especially with the solenoid and laser. But I don’t care about that as I’m a ‘builder’. I also make throw weights with my 3-D printer which is in...

    My rope launcher (pneumatic)

    Good idea. There certainly is such a circuit and i left space in the main handle under the grips for additional circuitry if needed. Now why didn’t I think of that first. Lol

    I never heard if it but Its always a good day when you can say such things.

    3D printed throw weights

    Makes for little margin for a 16oz weight. I think I left a link to the price of tungsten above somewhere.

    3D printed throw weights

    I’ll add this rare earth capture magnet which I’ll make a printed cover for similar in shape to the fatter ones. Subtract 7gm for the pedestal it’s sitting on. Scale won’t work with a magnet sitting on it it reads four times more. Lol

    3D printed throw weights

    This is with steel shot. A previous post in this thread has the calculations for different fill. The ABS is so light it only accounts for a few grams so not important.

    Thanks for the info. I’m Always looking to become better informed. The only problem with the hair trigger on the solenoid is the natural reaction to let go the trigger before the pressure chamber is completely evacuated. So then you need to burp the system afterward. I need to get it in my head...

    3D printed throw weights

    They do have tungsten shot though. Unfortunately once again it’s not a financially variable alternative.

    3D printed throw weights

    Why add the lead at all if its at such small percentages. Nonetheless it’s still lead in the environment. The website even labels it as toxic.

    3D printed throw weights

    I’m a rec climber so no stumper available. Be a great idea if i had one lying around though. Cheers

    3D printed throw weights

    Lol. If my choices are mercury over lead I’ll use lead. Jk. I’m pretty sure it’ll be steel all the way unless something nontoxic and heavier shows up that doesn’t break the bank like tungsten seems to. Pity that.

    Sorry that’s all pretty much over my head. Lol. I didn’t need to shoot to 300’. I was aiming for accuracy over distance.

    My rope launcher (pneumatic)

    Sobrobotics and hydraulics huh? I guess that means you could make a pretty cool automated log splitter/sorter. I’m actually looking at getting a log splitter and I’m already thinking about how I can hack it.

    Ottawa/Gatineau area rec climbers?

    Ugh, I hate FB. I’ll look into it though thanks.

    My rope launcher (pneumatic)

    No meaningful specs on Solinoid. That’s what you get out of China these days. No data sheets available. Its 1Mpa 12v. I Have a void in handle under grip for additional electronics if required. If I could’ve thought of the purpose for a Leonardo (Arduino) I would’ve put one there. Yeah I’ll keep...
