For #25 chain, you can fit #4 screws through the gaps between the rollers to fix it to something, although I don't know if this is how 233 does it or not. Another method is to drill a hole in the fixed structure that one end of a masterlink fits through. |

233, in 2011 at least, machines a part that appears to 'look' like a #25 chain link at either end and uses that to fix the chain to the stages. Here's a few pictures on their flickr. http://www.flickr.com/photos/thepinkteam/5787028180/ http://www.flickr.com/photos/thepinkteam/5787033770/ http://www.flickr.com/photos/thepink...n/photostream/ Last edited by thefro526 : 21-10-2013 at 14:35. |

Re: 233 telescoping arms how do they work?
Has anyone tried using these to attach chain? Specifically the K-1 style connector.

Maybe fill it up with pressurized air (like a piston out) to make it longer, and have a spring retract it. Maybe that will work for light/medium loads

Re: 233 telescoping arms how do they work?
If you could get the thing air tight (which would be really tough) I don't think it would be legal per the 2013 rules. I know a team wanted to fill a balloon with air from the compressor, but they weren't allowed to.

Re: 233 telescoping arms how do they work?
Except that if you don't do that with a COTS pneumatic cylinder, you're in violation of the rules (specifically R76). I don't see the ban on non-COTS pneumatic items going away anytime within the next decade, if not century. On top of the large volume of air you'd need for any reasonable extension length, and the fun of fitting at least one cylinder that long inside the arm, which make for a very nasty engineering challenge between them...

Re: 233 telescoping arms how do they work?
Am I the only one that likes the lead screw method?
Its beautiful. If you ask, they're more then happy to share some drawings on that arm. I have them saved somewhere. To me, it seems a little more simple and solid then all these chain runs. Cons being I'm not sure how you'd have multiple stages. Last edited by Brandon_L : 22-10-2013 at 00:49. |

I suppose another disadvantage of the leadscrew would be it's expense and inefficiency. Of course, it does look like a very elegant solution in that situation. |

Re: 233 telescoping arms how do they work?
Stuff got moved around in my google drive, and the previous album link now does not work. I got a PM to repost the link so here it is: https://drive.google.com/folderview?...&usp=sha ring
I will have to try to find a more permanent solution for the future. |
