I do violin and viola repair for local high school  and middle school orchestras… just the basics, new bridges, nut shaping, new pegs and the occasional crack. I’ve worked on five student grade violins over the past month and found that three of them had end pins that were 2mm - 3mm to the right of the fingerboard center line when viewing from the pin end of the instrument. The misalignment torques the tailpiece and puts lateral pressure on the bridge. On two of the violins, I plugged the hole and re-drilled & reamed it to be on center. Has anyone noticed this as a common issue with the inexpensive Chinese violins?

Good morning

i have and student violin that is about 120 yrs old. i  noticed tail peg pulled upward. 

i am not sure if the hole was mis-drilled, or if the pressure over time deformed the hole. i am new to the world of violin repair , so i thought to try my hand at repairing the tail peg. i am also concerned that the tail block may have been damaged over time, because where the two walls meet, there is a slight deformation.

i am open to any suggestions.

Hi Rosco, Bob,  I have noticed the end pin being pulled up and eventually out of the hole because of weak wood.  But because of their using jigs for everything to speed up production, its hard to think of why a hole would be off-center.  To fix my end hole, I mixed a soup of titebond and shavings from a bridge I was making.  It has held for 18 months so far.
I would enjoy hearing about your work with the schools and the brand name of the off-center violins.

also a Bob.
