Lower Tenor Bridge "apron" crack

[Roger Jolly]

Hi John,
                  You have loose bridge pins right along the speaking 
length of the bridge.   Drop the tension, pull the strings to the side, 
(looks as if those pins will just pull out with needle nose pliers.) Swab 
the holes with epoxy, and reinstall pins.   ( new bridge pins may be an idea)

With the tension off the bridge check to make sure that both the apron and 
root are glued to the board.  Repair as required. Fill crack with epoxy.

5 min epoxy will work OK if you heat it with a hair drier, it will run like 
water.   Makes for a speedy repair. 24 hr West Systems epoxy is stronger, 
if you want to make it a 2day job.

Regards Roger
