hi, everyone, i've just started my career as a strings repairer. So i got this case, and i don't know what to do next.

i got a broken neck cello from a customer, the cracked was clean and easy, but after i glued it back in exactly where it was, then i put the strings on and the strings happenly too closed to the fingerboard, unable to play.

what could i do to fix it. thanks you in advance.

Not to be mean, but I feel sorry for your customers if you are starting a CAREER repairing string instruments WITHOUT A MENTOR!

If the neck isn't in the same position, you probably did something wrong, but of course you'll never know if you don't have a mentor helping you through the learning process. Instead, your learning process will involve ruining many customers' cherished instruments.

you're mean, but come on, how did you tell if i have a mentor or not, i do have a mentor for a year, but i've never faced this case ever since i started.
and the neck is in the same position, exactly where it's broke, glued and clamp, but i have no idea why the strings are lower than before. FYI the cello was dropped from the back of a car to the ground.

How can you say it's exactly the same if it is so different that the action changed?

Anyway, I'm surprised you don't know how to raise the action after a year with a mentor.

ok , well if the strings are lower , you either set the neck wrong, the bridge was never right , or the belly has lowered , the nut shrank, the fingerboard expanded, those are the only options I can think of

Are you unable to contact your mentor about this? Just seems odd that you are asking here and also that you don't know how to remedy a set-up like this. With all due respect, you may need more time with a mentor before going off on your own.

@kjb thank you for your contribute, I got no idea how and why it's lower.
@buckhenry its the only bridge my customer has and its an old bridge.
@Jimbeaux I 've just finish my course, and like I told you I'm never had a case like this when I with my mentor.

If the neck is straight on the back and the fingerboard is atttached to the neck correctly then there is another problem somewhere. KJB lists several possibilities. Download a list of cello measurements and start checking. Something somewhere is off. Also ask the owner if he or she played this cello before the instrument was brought to you for repair. It may be that the bridge provided never fit the instrument in question. R/

I'm loving this Mystery... Lots of questions...
Vinh, were you familiar with this instrument before the damage occured?
Could the neck block have been loosened ?
could the neck/block joint have come loose?
Is the post still in place?
Could the bridge have originally been closer to the top?
I sincerely hope you get this fixed..
Good Luck

It might be helpful to know exactly where the break was, and exactly how you repaired it. Also how high are the strings now? I guess measured at the end of the fingerboard.
I guess if you don't want to undo your repair, and the string height isn't too bad, you could make a new bridge, or even shim this one temporarily. I'm sure cello specifications are available online somewhere. Perhaps the instrument was damaged in some other way you haven't noticed.

I would assume that the nut is in place, except that, from your posts so far, I wouldn't assume anything. It is pretty obvious that something is out of line, but if you can't see that I don't know how we are supposed to.

@UsuallyPickin it's  the only bridge they have. sir. And i have friends who are bass, violin, cello pro players, they told me that there's no standard for instrumentals.
@TuneWeaver: i have lots of questions as well.
- I have never touch the cello before it's incident
- the break is at the neck block https://imgs.info/i/kgyGN
- soundpost still in it's place.
 thanks you, i decide to cut a higher bridge.
@DougD 
the string high is enough to make it  buzzing when you play even with finger. i decide to cut a higher bridge, and i put this thread on, because i want to learn how to prevent this to happen again in the future.
@captainhook if i can see what the problem was, i wouldn't put the case online for asking :D

It would be possible that the joint repair you made still is not as tight as you might think..Given the long length of the neck, even if the joint is the thickness off a sheet of paper, not tight enough on ONE side, could cause significant misalignment issues.. I'd double check the work you've already done, and possible redo it.. If possible, place the finger board in the desired angle and keep it there while the block is clamped....??

Yes. Its hard to tell from the photo, but the neck angle may be too far back. Also, what's all the red stuff at the joint? Or did you just highlight it for better visibility?

I would not just make a higher bridge; that neglects addressing the problem.

There is not a lot of information about the what the actual original issue, and lack of info or repair evaluation and procedure was. That  photo link doesn't provide much info as is it is clearly not the actual cello in question.

As Lee mentioned... it's likely due to the neck joint. It was a big jolt. Doesn't seem like it got properly inspected. One guess would be that the joint did not get evaluated or addressed correctly; properly cleaned; dry fit checked and/or properly re-glued... and thus might still be a problem. The jolt might have also knocked the block loose (unglued). The heel button should also be inspected, it plays an important part to neck angle stability.

A proper evaluation needs to done. The neck might have to come back off. Might take it to an proper repairman. (esp if not your instrument).

Hi you guys, sorry for the late responding. I figured why the strings are being low. I was trying to tune the cello,then there was weird noise from the back, I checked it there and saw that the back was being splitted (it's a 2 pieces back). So I glued it back in and everything is fine. Thanks you guys so much for helping.

Thanks for that response.. So you DID do  a good job of gluing the neck but failed to notice the back.. But you DID finally notice it... Congratulations!!!!! Are the blocks still in place?

You are better of to cut a higher bridge. But before doing that, you may have to look at any underlying issues. That will be more appropriate to do.
