Re: [WISPA] bare conduits
Yes Mrlon, Pulling cable in NoCAL, we made a 'y' for the compressor, Air in one side sponge-on-line in the straight side. Gave it to the guys, one was a careful guy. A little while later I pulled up to the site and the guys were all laughing, watch this ron!, they set it up for a 300' 'blow' and opened the air valve. That sponge flew about 30' in the air. Can be very dangerous,thou. -Original Message- From: Marlon K.

RE: [WISPA] bare conduits
get a shop vac. get a box of pull string or a long enough piece of lightweight string. get a tennis ball (or whiffle ball) and tie the string to it. Turn on shop vac. Suck the ball through. Don't laugh. It'll work! -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Butch Evans Sent: Friday, December 01, 2006 4:55 PM To: [EMAIL PROTECTED]; WISPA General List Subject: Re: [WISPA] bare conduits On Fri, 1 Dec 2006, chris cooper wrote: Im looking at a project that requires connectivity between multiple buildings on the same campus.

If the conduit is dry, you can sometimes use a vacuum on one end and it will pull a small string through. You may, also, try to use a pull ribbon. When you do get something in there, be sure to pull through another ribbon/string to use to pull with next time. -- Butch Evans Network Engineering and Security Consulting 573-276-2879 http://www.butchevans.com/ Mikrotik Certified Consultant (http://www.mikrotik.com/consultants.html) -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
RE: [WISPA] bare conduits
Chris, First, if there is an open 4 conduit, you'd never want to run a cable by itself --that'd be considered a major waste of the conduit investment in place. Instead, the proper thing would be to install 3 to 4 PVC innerducts. These are generally about 1.5 OD and can be ordered with pull string. You can also install innerduct without string, then blow string in or use long fish tape or fiber glass router to thread the duct. Blowing requires a little tool, but one can be fashioned with a good shop vac. You'll need a mouse, which is a foam and plastic piece with an eye to thread a lightweight line. Blow or suck the mouse through with the line attached, then use the light line to pull in the heavier pull string or rope.

Re: [WISPA] bare conduits
I have heard of people using something resembling a ping pong ball, pressure on one end and vacuum on the other to push a small string/ribbon through. Once that is done you just pull bigger string until you get the size you want.
