If I absolutely had to daisy-chain the poles, I'd look at using Dinse welding cable connectors to mechanically hold the lengths together. They are nice, tight twist-lock connectors and the price is entirely reasonable for what you get. |

However the tension cord prevents the user from separating the 2 halves should they require only a 5' pole. The tab and slot is where my thinking is going. Let's start with 2 - 3/4" Dia wood poles. Drill a hole for a 1/4" dowel into both. Remember, there is to bending force, only compression. Dado cut across the ends forming 2 slots and 2 tabs in both. Place loose fitting dowel with glue into 1. (You could start off with tubing and do the same.) Done! What do you think? |

They'd soon split and fall apart due to unforseen side pressures unless the slot was short and the doweling long. Why are you not buying standard, off-the-shelf light bulb tools? Another consideration is the spring-loaded dowel like pool skimmers use. It prevents twisting or pulling apart until the dowel is depressed.

Gotta twist off a hard to remove floodlight, etc. Swage one pipe so they slide together, "Wishbone" style pin lock like used on swimming pool vacuum poles. But I use a standard twist-to-lock painters roller style pole to change light bulbs all the time. If you have to put enough torque on the pole that overrides the locking tension on the pole sections, you've got bigger problems with either the lamps or the sockets. First, you have to define the REAL problem, then you can solve it. Cheap imported aluminum base lamps and cheap aluminum shell sockets are always bad separately, but when they are combined and you add any moisture at all and allow time for them to corrode to each other... Buy the better brass or nickel plated brass based lamps, and brass shell sockets. Then they'll come apart without a big fight. -- Bruce -- |

Dave Ford recommends it as a brake and caliper lube instead of the high- temp grease they used to sell. Be careful about using it in an electronics facility, though, because it can interfere with soldering. Silicones like this are prohibited on subs because the vapor creates abrasive SiC in the sparks of electric motor brushes. Jim Wilkins |
