Post subject:  Pinless bridge design

So once I finish the three electrics I am doing, I plan on doing my first acoustic guitar. I am planing on doing a pinless bridge and have been trying to decide which style to go with (Doolin or Breedlove/Ovation style). Then I came across this, and it really intrigues me. Has anyone tried anything like this?

That seems to be borrowed from Alvarez.

Why?

I haven't tried it, but I understand you'd probablly be reducing bridge weight substancially, which might be interesting. But if there is just a bridge plate under those holes, I'd be worry about them maintining such tension without eventually braking or being somewhat damaged considerably over time. I there is more than just a bridge plate, then I guess that sort of reduces the bridge weight reduction concept.

That really is an elegant design. I believe, by reading the description below the picture on the website: "....the aluminum reinforced keyways are located at distance to reduce sheer tension and increase down force...." that there is a strip of aluminum under the top.

Interesting design.
The Yairi bridge has pins,
and is interesting as well.http://www.yairi.com/gtrsktor/indv_dtl/dcb_info.html

That makes sense.

Eiichi Ishikawa in Vancouver does a pinless bridge like this. I first saw one there around 1989.

do you guys see a need for there to be an aluminum reinforcement under there? Would a normal bridge plate made out of ebony or rosewood work? Or, would it need to be thicker?

Except for the eyelets, that is the same as the Hana Lima tie-through bridge for ukuleles.

I have never heard of one pulling out.
