Re: 145 is D-O-N-E
 

We're using 8020 and the way it's set up makes it somewhat difficult to run the tubing 100% effectively. We have a pretty good setup right now, but we all would feel more secure with a better tubing set-up.

Re: 145 is D-O-N-E
 

In that case a coil might be your best option. Be sure to used different colored tubing for the open and close valves so you'll be able to tell which is which.

Re: 145 is D-O-N-E
 

Yeah, we have figured that out. we have two cylinders that lft about 7' so the self coinling would just help to keep everything in line and prevent it from getting caught up in the actal lift. thanks for the help.

Re: 145 is D-O-N-E
 

On 375 we've always used Bosch extrusion, and the way we used to run our tubing was running it through one of the unused side "channels."

Re: 145 is D-O-N-E
 

But in our situation, we have a three stage lift that we can't really do that on. I think we will just try and figure out how to use a coil.

Oh dear. GDC has said that's illegal: http://forums.usfirst.org/showthread.php?t=8802

I'd suggest you buy some coiled tube so you can replace it at your first regional.

we have dont it in the past, and many teams have done it.

This is what <R87> states

Additional pneumatic system items specifically permitted on 2008 FRC ROBOTS include:

One or two additional Clippard air storage tanks (Clippard Part Number AVT-32-16),
equivalent to those provided in the kit. This means that up to four, and no more, Clippard air
storage tanks can be used on the ROBOT.

Pneumatic pressure relief valves identical to those provided in the Kit Of Parts (Parker Part
Number PV609-2).

Prior year FIRST Kit Of Parts solenoid valves, and pneumatic tubing may be used in
addition to those provided in the 2008 Kit Of Parts. Their costs must be accounted for as
explained in Section 8.3.3 Budget Constraints.

Additional 0.160” inch inside diameter pneumatic tubing functionally equivalent to that
provided in the Kit Of Parts, with the pressure rating clearly factory-printed on the exterior of
the tubing (note: alternate tubing colors are acceptable).

Pressure transducers may be used as long as they are rated to at least 125psi.

For the purposes of the FIRST competition, a device that creates a vacuum is not
considered to be a pneumatic device and is allowed. This includes, but is not limited to,
venturi-type vacuum generators and off-the-shelf vacuum devices (as long as they are
powered by provided or permitted motors).

For the purposes of the FIRST competition, closed-loop pneumatic (gas) shocks are not
considered pneumatic devices, and are permitted additions to the ROBOT.


It states nothing about heat treating the tubing
