Intake cord
 

What kind of polycord does everyone like to use? Like to find something easy to work with.

Re: Intake cord
 

Polycord is a very popular choice among FRC teams. Do a google search or a forum search to find more information to help you out. If you need help on the easiest way to join Polycord without any special tooling, PM me.

Note that Polycord is a brand name, and these cords you see on most intakes are known as urethane belts.
We source our cord from McMaster-Carr.

We also source our cord from McMaster as the lead times are nice and short. As to the easiest cord to use, it all depends on how exactly you want to use the cord.

This is the most popular orange belting for intakes that most teams use.

Round belting:

Flat belting:

For belting this together I find this video very useful from Triple Helix 2363!
It's about how to connect them together if you buy the belting on a roll.

The linked video shows some good tips for joining the belt except DON'T use a flame to heat the urethane. Apart from the general hazard of fire (and that you can't use a flame at competition) BURNING URETHANE PRODUCES TOXIC FUMES.

Simple solution: USE A HEAT GUN instead. Shield areas you don't want to heat with a piece of aluminium. Careful, that will get hot too.

What is the practical difference between the hollow core and solid core belts? Are solid core more commonly used? Do the hollow core deform more easily or do they have a tenancy to "flatten"?

Re: Intake cord
 

The hollow core has the advantage or disadvantage of a mechanical joining system. It hard to push the barb into the tube & you have to be careful not to damage the hose barbs. The solid ones have to be welded. We have always used the hollow ones.

Has anyone done any testing with different shores?
