    3D printed throw weights

    Yes, thanks. Always room for improvement though. The D ring is a good addition over the paracord. Flys well and high for 7.5oz. Moves through tree well. TPU provides resilient tough base without getting in the way ( higher friction ) so the low fiction ABS can slide around easily with being...

    3D printed throw weights

    New bigger model with D ring. Once adhesive drys (24hrs) I start testing.

    3D printed throw weights

    My next attempt will be with urethane adhesive ( Gorilla glue). I’ve also add key slots to the design at the adhesive site and Will be incorporating a special (read: secret) material internally to aid in the dead blow effect. I’ve also modified the TPU surface area for greater energy...

    3D printed throw weights

    Well at this point I think it’s probably impossible to tell that until I try the product. I don’t know how viscous it is or if I will need to use key slots (hollows to hold glue) to increase surface area. I tried looking at other manufacturers flexible epoxies and they’re all expensive.

    I requested a sample but I don’t think that’s going to Pan out.

    3M suggests this flexible epoxy DP100 Plus. 47$ For 50ml. Ouch >-:-<

    3D printed throw weights

    Apparently 3M is reporting that they are backed up pretty bad for inquiries so I’m anticipating a delay before they get back to me.

    3D printed throw weights

    I’ve used gorilla glue (urethane) to great success with ABS. My only concern is the flexibility of the TPU not playing nice with the gorilla glue. 3M has a very good spray adhesive I may try at least it’ll retain some flexibility.

    My rope launcher (pneumatic)

    Essentially yes. The ends being highly ductible while the core is stiff ABS sized to the tube diameter.

    3D printed throw weights

    Before it came apart it was flying well. moving through the bush well. I sent it right through a tangle of brambles and scrub brush and It didn’t get tangled coming out. The dead blow shots I made against the bole shows that that part needs tweaking though. Definitely could use more weight though.

    3D printed throw weights

    Ya know that’s a DAMN fine tip Tom, thank you! Now why didn’t I think of that. LOL. I’ll start looking up contact information right away.

    3D printed throw weights

    Well now I know RTV sealant is the wrong adhesive. So I have to find another flexible adhesive that’ll work with these polymers or the next option is a using a mechanical fit which means a complete design modification. So it’s Back to the drawing board. :-/ Anybody here have any experience in...

    3D printed throw weights

    Vapour smoothed. Feels good. Testing next. I’m sure I’m going to next make a 14oz with some design improvements with the TPU (green) part.

    My rope launcher (pneumatic)

    One idea Is to possibly use the flexible TPU on both the top and bottom. With ABS in the middle fitted to the diameter of the launch tube. Making a secure connection point to the flexible polymer (TPU) could be an interesting challenge but I have a few ideas on how to possibly overcome that...

    3D printed throw weights

    You’re right there’s a very little selection of fittings for schedule 80. I’m sorry you’re having friction problems with your throw bags. I guess that’s the benefit of printing my own, when they wear out I just replace them. Like you I made my launcher to completely disassemble. The primary...

    My rope launcher (pneumatic)

    The carrot was never designed for the Launcher it’s for hand throwing only. When I designed The Carrot I assume that most people did not have a pneumatic launcher. :) i’m happy with the launch weights I have now and how they operate but I will be reviewing that design in the future to see if I...

    3D printed throw weights

    I use a digital microcaliper to measure the barrel. Actually I’m a perfectionist so I measure everything. Lol I personally found the 16 oz commercial throw bag fit perfectly in my one and a half inch barrel. I made my barrels replaceable. They just screw off and I can screw another one on. So...

    3D printed throw weights

    Since I make my own weights with a 3-D printer I have an accuracy of 0.4 mm. Less if a 0.1 nozzle is used. So I haven’t needed wadding. The fit is tight enough that I actually have to use a tamping rod to push the weight to the bottom of the tube. When I initially made my first shot it was with...

    My rope launcher (pneumatic)

    Thanks to Mr. Newton the high mass and inertia i think Helps mitigate some of that.
