Pinless bridge troubles X30
One of my strings keeps wanting to come loose from my pinless bridge. I threw it through a little washer for the moment, but I think I'm going to 3D print this part in aluminum and glue it under the bridge. Weighs the same as the 6 bridge pins supplied by Emerald. We're looking at it from inside the guitar, so the string will come down through the hole and then catch against the little ramp there. Thoughts?

This guitar was originally supplied with bridge pins? It is the one where you've been inserting the bridge pins from inside?

Seems a good approach. First however, have you asked Alastair about what is going on?

Separate question...would such a part work on a non-pinless bridge too?

That's a great design effort. What CAD program do you use? I have a few regular PLA type 3D printers. I do see a couple of things you may want to think about.
The inside bevel where the string goes through the base hole appears to be backwards and may tend to cut into the string. The gap between the uprights are currently the same for all strings. That measurement will be critical to accommodating various string diameters while excluding the eyes. The uprights may be a little stronger if those gaps were graduated. I would add more meat to the forward side of the uprights. There's a lot of force pulling forward.

I'm more curious about why one string keeps coming loose. What's different about the bridge in that position?

Along with the slight PITA of getting it to come loose for string changes, I worry that this one might at some point wear farther (further?) and start to slip. Should this happen I would likely just send it back and have Alistair convert it to a pin type bridge (assuming this can be done) and also have the bridge tinted at the same time. But I'm getting way ahead of myself. I've only done the one string change so far and don't do them all that often as I typically only change strings 3-4 times a year, if that. But I would like to hear more details about the how the slippage issue came to be. |

I think it's Brazilian but maybe Emerald should make a CF version so that you can travel with it?

How about A dome with a center cut to make the two posts so that the string ball end stays secure.
with a big enough hole in the back for entry into the core. Last edited by Gitaman; 02-23-2019 at 02:18 PM. |

or just curl the posts up and back like horns... All the way to the base leaving just enough space for the string to pass by. It will be tough to incidentally slide back out.

Nice design...seems like it should work.
I've slotted wooden guitar's bridges using tabletop jigsaw blades (by hand)...maybe a slightly deeper slot would fix it. Though IMO, "stock" pinless bridges, especially with CF, shouldn't slip or fail ever. Have you contacted Emerald? |

Ovation has an excellent pinless bridge design. Never had one fail in owning many guitars of the brand over many years. Maybe Emerald could adapt a variation of the Ovation design?

Can you draw a picture of what you're describing so we can see it?
