 ```Gerald's note prompts me to ask a related question: What techniques are folks using for the first pull through a conduit? Background: Like Gerald, I plan to have a 400ft+ run of 4 inch corrugated irrigation tubing. A 400ft fish tape would be hard to find/expensive, but I need to get a pull rope through the conduit before I can do the first cable pull (LDF5-50) How? 73 David G3WGN WJ6O ------------------------------ Date: Sun, 6 May 2012 15:13:42 -0300 From: "VE1DT-Towertalk" Subject: [TowerTalk] Wire Soap - How Much? To: Message-ID: <001801cd2bb3\$f96e2ce0\$ec4a86a0\$@seaside.ns.ca> Content-Type: text/plain; charset="us-ascii" I've no experience in running cables through conduit, but I do know that I want to use a cable lube. I can get Klein #15028 1 quart bottles locally, but I don't know how much I will need. Also, I know I don't want to run out part way. In browsing through the archives, the answer I keep seeing is "lots". In my case, I am using 4" diameter corrugated irrigation tubing for a couple of LMR600 cables, a couple rotator cables and a few CAT5 cables. Total length is 400 feet. Worst case would be the volume of the conduit. Using the formula, pi *r^2 *length tells me about 30 gallons. I am not planning on doing that. Polywater http://www.youtube.com/watch?v=kr87VQcJeK8 says to use this formula for PolywaterJ: Gallons = 0.0015 * Diameter(inches) * Length(feet). This comes out to 2.4 gallons. Using 1 quart bottles, this comes to about \$150 here. Grainger also sells larger 1 gallon containers of 3M WL lube at about the same price as two of the Klein one quart squeeze bottles. Does 3 gallons sound about right? -- Gerald Boutin, VE1DT ******************************** _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
