Most front doors feature a standard door knocker that consists of a piece of metal on a hinge. This piece of metal simply strikes the normal surface of the door creating an ugly clunking, rapping, clanking type sound.
The idea is a small inset modification set into the door at the spot where the knocker strikes the door surface. This could be in pre-built doors or a "kit" for retrofitting existing doors (saw out a square and insert the "Nice Knocker" kit..etc.)
Some kit options: Woodblock Kit- Uses a musical type "woodblock" so that the door knocker creates a pleasing "CHOCK CHOCK" sound.
Gong, or jamaican steel drum Kit- For a unique metallic sound
Christopher Walken Celebrity Endorsed Kit - Cowbell knocker tone-- Enjoyer, May 18 2004 [markedfordeletion] widely known to exist. This is not a DIY website.-- etherman, May 18 2004 [etherman]: Can you add a citation to back up your mfd, please?-- bristolz, May 18 2004 <sarcastic as hell> Well, seeing as how [etherman] has been here longer than anyone else, then maybe we should all listen to him. </sah>
I don't really see "this is not a DIY website" as even remotely valid grounds to MFD an idea. Its not a recipe, its not flavor, its an idea about giving door knockers a different sound.-- Letsbuildafort, May 18 2004 Clarified the idea a bit. I suppose it would be easy to confuse this idea with DIY because of the different options I gave for the "striking area". They are just variations on the central idea, which is a special inset into a door to create pleasing sounds when struck by a standard knocker.-- Enjoyer, May 18 2004 I thought this would be a door knocker in the shape of a breast (in which case I would have mentioned that I met someone who built that.)-- jutta, May 18 2004 wondering why they don't come in pairs?
also bothered why the woodblock differs from the wooden door.
doorknockers here have a metal knocking plate.-- po, May 18 2004 jutta: cute - could you post a picture? Enjoyer: chimes and xylophones are Baked as door knockers, though you are usually required to strike them with a hammer, rather than raise a knocker.-- DrCurry, May 18 2004 random, halfbakery
