Re: Chain vs. Belts?!?
I'll try and slip the DarkSoul tool in there, but most of the build members on my team are unwilling to try out #25 chain, due to strength and the fact that we have some #35 sprockets left over. I'm working on turning them to the DarkSide (bad joke, couldn't resist) and run #25 on at least manipulators and such, but we'll see how it goes.

I understand the concerns with #25, although we ran #25 on our shooter/intake and had zero issues, even with a master link. For context we ran 2 22T sprockets from VexPro driven by a MiniCIM with a 4:1 VersaPlanatary. In my opinion, it's a useful option to have where #35 would be overkill. |

I certainly understand; I designed our 2016 bot with #25 chain in mind for all of the sub-assemblies except drive, but the rest of the team was worried about it, so we went with #35. We had experience with #35 from 2015, and we already had the tools we needed, so it was the quicker option at the time. By the time Kickoff for 2017 rolls around, I hope to have the younger members trained and the shop outfitted so they feel comfortable using both and can determine which is better for different situations. |

Re: Chain vs. Belts?!?
A 4mm metric allen key is recommended( what it is designed for) which is handy for us being an Australian team and using a lot of metric( M5 and M6) hardware. In reality 5/32 inch is 3.97mm so there isn't exactly a big difference, probably not worth worrying about.

0.03mm is ~0.001" so it's well within the tolerance on the hex and on allen keys. |

Re: Chain vs. Belts?!?
I'm not the best person to answer this because I was just getting advice about the same part earlier, but I believe the distinct advantage with the tool GeeTwo and others were referring to is that you can use it to break and reform the chain. The threaded rods can be used to push the pins out or push the pins back in to create continuous chain loops without master links.

ONE VERY IMPORTANT NOTE!!! When breaking the chain with these tools DO NOT FULLY REMOVE THE PIN!! This makes re-assembling it nearly impossible. Its better to push it out until it is stuck in just the last thin piece of the chain. This keeps it aligned and in place to push back and re assemble when needed. |

Re: Chain vs. Belts?!?
This is anot extremely common questions on CD and TBH this thread is TL;DR.
My personal take on belt verses chain is dependent on where it is on the bot. If it is on the drive train I use Center to Center chain #25 and forget about it. In my experience the stretch is small enough that it has no noticeable impact on the bots performance. Everywhere else I use belts and put them in tub.

Never underestimate a CD thread's ability to get derailed. EDIT- Oh, and there's a brief excursion of people discussing polycord as an alternative to belts and chain. The more derailment, the better! Last edited by Cothron Theiss : 19-07-2016 at 15:21. |

Re: Chain vs. Belts?!?
I know for the past page and a half we have been talking about tools for chain. But back to the belts... What sizes would you recommend. I know 100% that the sizes may vary between years and robots. But I'm not sure on the standard belt sizes due to the inexperience with the topic.
Thanks, Drew Ps. This is very helpful and I appreciate it! |
