The Crappernater - a spider bridge square neck resophonic guitar

Top view .

Side view. The spider will sit on the black plate, acoustically coupling its edge to the cone. The very edge of the black plate will sit on a retaining ring attached to the top of the guitar.

The top, with retaining rings and spacers, spider, and cone.

The spider in place.

The cone in place.

Retaining ring (that the periphery of the cone sits on) in place.

This is the top of the guitar - so everything is upside down here.

 

[crazydoc]

Drilled a hole in the cone, and glued on a nut.

Which will accept this screw down through the bridge and into the cone. Adjusting the screw will change the tension between the bridge and the cone, and thus the tone of the guitar somewhat.

Tuners are piano pins (I got an almost full box of 250 at a garage sale for 75 cents.)

The nut.

Not happy when I told him I needed his bone.

Sawed .

Shaped .

I decided to use the bone nut for another guitar, and, in keeping with the nature of this project, made a crappy wooden one. I made a tailpiece out of some scrap copy machine metal.

This is the initial string up. I was happy that the spider didn't cave in.

Assembled with deck screws.

I tried to make a cover from a pizza pan. Made a pattern to center punch the holes.

 

[crazydoc]

Tore them out when I tried to enlarge the center ones.

 

[crazydoc]

I thought I'd try it anyway, to see how the idea worked. It didn't - the metal was too thin and rattled.

Looks like a fun build, but don't let the guys in the drum forum get wind of it- they will rip you a new one, and say that if it ain't made by some "instrument company," it ain't a musical instrument.

Greg L is the worst of the bunch.

I'd rename the cone "the composter".
This looks like you're having fun.
Poor doggy!
Keep the snaps coming please.
What could you do with a urinal?
