Re: Fuel leaves behind a thin film
Embrace the residue. Let the residue become part of your shooter wheels. Then you never have to worry about cleaning it off

Re: Fuel leaves behind a thin film
That would be okay if it weren't polyethylene.

Re: Fuel leaves behind a thin film
Sounds like you might want to make your shooter so it works well after you shoot 200 or so balls with it. That's the point he's trying to make.....if you set up your shooter so it can just barely make the shots when the wheel is new, then you're going to have trouble. You want to set it up so it shoots too far when the wheel is used and has turned yellow, and dial it back a little.

Re: Fuel leaves behind a thin film
We have not seen this in any of our testing.

Re: Fuel leaves behind a thin film
I suspect this starts cropping up when you move from gravity feeding into a shooter wheel to controlled conveyor feeding. If you don't get the spacing right, the conveyor is still holding the fuel when it contacts the shooter wheel, and the shooter wheel slips until it gets enough grip to rip the fuel out of the conveyor. At least, that's my experience from multiwheel frisbee shooters.
Basically, anything where physics is going to force the wheel to slip at high speed on the fuel for a prolonged time is probably going to melt some of it off. |

Re: Fuel leaves behind a thin film
This is an issue for every single kind of shooter wheel, intake mechanism, etc. that we've tested. Some tips:
1. Coarse sandpaper, with pressure and motion applied parallel to the axis of rotation (i.e. left to right) will quickly (albeit, not easily) strip off this material. 2. Some material retains their traction qualities better than others when coated with this clear stuff. Think about the different factors that cause adhesion beyond just if the rubber is grippy or not, such as compliance. Big hint there. 3. Get the RPM right for your wheels. The more slippage between the ball and the wheel, the worse the wear is going to be. Everyone who did Frisbees in 2013 knows this. So if you're relying on over-driving your wheel open-loop and just taking the speed loss, you're doing it wrong. 4. Load the shooter as fast as your mechanism can justify. The less speed differential between your ball speed at the indexer and your ball speed at the shooter, the less material gets stuck due to lower slippage. (Of course, there may be more material on your indexer surface, but that's less of a big deal) 5. Pick kids for pit crew who love sanding things. |

Re: Fuel leaves behind a thin film
QFT. If you can get a student who's excited about maintenance in your pit, the'll make sure it gets looked after between each match.

Re: Fuel leaves behind a thin film
Is there any prolonged effect of the polyethylene buildup on the shooter wheels even after scraping it all off every match? How often are we all going to have to replace our shooter wheels?
From testing shooter prototypes in the snow, even a little bit of ice or water buildup reduces shooter speed far more significantly than I ever would have thought. |

Re: Fuel leaves behind a thin film
We have not seen this in our testing either. Our compression is fairly low so that could be part of it.

Re: Fuel leaves behind a thin film
Same here, though we'll be looking out for it now...
