I just glued the bridge onto the skeleton ukulele.
I used the 433.05 ish measurement according to StewMac.com
Bridge placement for 431.000mm scale length
|Ukulele (Non-compensated bridge)|
Measurement is from the nut to the "break-point" of the string at the peak of the saddle.
I drew around the bridge with a pencil so I could put glue down on the body as well as the bridge itself.
In order to get the pencil lines off afterward I tried some prewash stain remover and a artists brush to clean it off and it worked like a charm. In the past removing graphite from plastic has been problematic for me.
