Airplanes & Sewer Clamps
To All:
I recently mentioned laminating the bow of a rudder using 'sewer clamps.' (See: 'Whittle Your Own Airplane.') Standard stuff if you're building a wooden airplane. Wooden strips, eighth inch thick, slathered with glue, bent around some nails or form-blocks protected by waxed paper, clamped together and to the form blocks. SOP for making the curvey bits. Wing tips. Elevator. Rudder. Turtle deck bows. Lotsa curvey bits on a wooden airplane which is why making such bows is common stuff. Including the use of sewer clamps, which are nothing more than a 10' length of 4" diameter plastic soil pipe sliced into pieces three-quarters of an inch wide. After the slicing comes the slitting then cleaning off the furze. You end up with a ring of tough plastic, slit at some point so you can pry it open, clamp it onto things. Bandaw is the weapon of choice. Takes mebbe half an hour to make yourself about 150 clamps. Like a politician, sewer pipe clamps are cheap, easy and common :-) But obviously not as common as I thought. I've since received half a dozen queries wanting to know whathell a sewer clamp is. Nowyahno :-) Sewer clamps come in several sizes & flavors. Little ones, you make outta PVC water pipe, use them for making little stuff like ribs. Big ones you make outta BIG pipe, ABS, PVC or even fiberglas. You can even make yourself a pair of Sewer Clamp Pliers, allowing you to open and set the clamp with one hand. Need more pressure? Slice it thicker. Need more reach? Find a bigger pipe. Building on the Cheap, you can't just throw money at a probelm, you have to outwit that sucker. Sewer pipe clamps are a nice example of outwitability :-) -R.S.Hoover |

Old boatbuilder trick. Been there, done that, really works!
Used to be a bunch of boatbuilding sites with pictures of the entire process, but doing a cursory search of my favorites, these guys have abandoned their web-sites and probably are too busy building or sailing to accomodate pictures of the process. Try it, you'll like it! Drew |

outwit that sucker. Sewer pipe clamps are a nice example of outwitability :-) Great idea! I am always looking for the "poor man's way" of solving problems. |

For those who need pictures to understand things: http://www.hanalima.com/tooltips_pvcclamp.shtml Bob, gonna tell us more about the Sewer Clamp Pliers? I can picture what such a tool might be like, but you've done it, so, tell. I've also seen these clamps with two dowels stuck in holes about 160 and 200 degrees away from the slit; squeze the dowels together to open the clamp. |
