EX-4: Bridge Position / Scale length problem

[MoSch]

Sooo, it's been a while... job and health ain't friends of my bass project ;-)

But meanwhile i got myself a japanese saw and dowels and practiced on cutting boards (i also used those to practice shaping the headstock). Well... some more training until i feel fully prepared, but it gets more promising.
Also I practiced with the cheap drill press - that won't work, I will find someone with the real thing.

Nevertheless I startet thinking about the bushings to mount the bridge.
Especially if I want to drill suitable holes I want to understand how they are working first. So I got some more questions:

1. Are the bushings basically blind rivet nuts that are tightened by deformation by the screw or is it a press-fitted ferrule? In the latter case the dimesnions of the hole would be even more important...
I cannot find proper descriptions of those bushings (and the Babicz homepage isn't too helpful either: https://www.fullcontacthardware.com/...g-body-inserts )

2. Is there a reason why the bridge isn't mountet with the screws through the whole body and sleeve nuts on the back? This seemed to me a very strong connection?

It's this one. I have found that calling or emailing the mfg sometimes gets you the info better than searching web pages. Babicz wrote back the one time I asked them a question... FWIW.

Not that I have ever seen written. I think it may be to keep the back as clean as possible, but Danelectros have screws in the back. I also think that is why some three point bridges are string-through. To help keep the bridge in place.

Hello :-)

short update:
I finally had the guts to fill the wrong bridge holes!











I'm quite happy with the result of my first try :-)

I first made some fitting dowels by putting by putting wooden bars in my drill and using a file while rotating until they were thin enough (the holes seemed not to be of metric measure so I couldn't find suitable dowels here).

Then I glued those sticks into the wrong holes.

Next day I cut them with the japanese saw (indeed a very interesting tool that I didn't know before!).

And finally sandpaper.

It wasn't as bad as expected! Thank you for the encouragement!!!
