Re: Tubing for ball intake
What about orange urethane cord? Would that work well too?
We haven't built any intakes with urethane cord yet, but we have used in the past. From my experiences with it, it seems like it would work. It's also cheap and easy to build with. |

Re: Tubing for ball intake
To share our recent experience with the McMaster 1" belt:
http://www.harborfreight.com/130-wat...ife-60313.html This hot knife along with some clamped angle iron works wonders in joining the flat belts quickly. It's probably overkill for the solid core round tubing. Also, I've seen a ~10% length reduction recommended for proper tension. This may be feasible for the small diameter round tubing, but you might find that stretching the flat belts that much makes intake assembly, well, difficult. I'm finding that we have sufficient belt tension by simply ignoring roller diameters. |

Re: Tubing for ball intake
Is it just me or are people talking about 3 different things? The structural tube for a roller, gripping material to put on the roller, and urethane belting.

Re: Tubing for ball intake
No, there is definitely 3 different conversations in this thread.

Re: Tubing for ball intake
Yup, there are 3 different answers for an ambiguous question here...

You cannot pull it on at all. You will need to use compressed air and someone with a reasonably strong arm. Zip-tie/safety-wire one end of the tubing to an air nozzle so that you get a good seal. Next you must plug off your aluminum roller so that air can't flow through it. one person controls air flow, the other holds the tube and tubing and does the hard part. turn on the air and begin pushing the latex on to the aluminum, DO NOT FOR ANY REASON clamp your hand down on the aluminum tube underneath the latex(your hand should never be that far up anyway) or you will get a 100psi balloon animal with a desire to pop. Alternate the airflow on and off to let you move your grip lower on the latex. If you do not fully understand I can make a youtube video tutorial on Wednesday. |

Also I just ordered the components to try this out for myself... should be interesting. Last edited by Skyehawk : 30-01-2017 at 13:52. |

I will post a reminder in our team slack to put the video together during our next meeting on Wed. |

How do you adjust the ends of the rollers? i.e. move the last inch of the latex up to your mark on the Al tubing? |

Re: Tubing for ball intake
We would appreciate that video very much as we are putting our intake together this week with the same set up for the first time.

The "sticky when dry" caveat, however, should not be ignored. A 20" wide roller has only the two ends of the rubber tubing to facilitate evaporation. Four sections, each 5" wide, however, might allow for fairly rapid evaporation of the hairspray... |

Re: Tubing for ball intake
I might as well do a round belt welding video at the same time. What other intake and conveyor stuff would you like me to add to the to-do list?

Re: Tubing for ball intake
How to make poly round belts have identical tensions so they don't 'wander' on the rollers.
