How can I keep the sound post standing?
How can I keep the sound post standing, if I am working to check my pegs?
Strings are expected to unwind. How can I make sure that the sound post won't move?
Thank you in advance!!
Pass a soft belt around the corpus between the bridge and fingerboard, putting a small and benign object (perhaps your rosin in its box?) under it below the E string. Tighten to compress the table under the strings. You can now release the strings with less anxiety.
I have long used that technique successfully when changing a tailpiece, but without Peter's thoughtful "benign object". I must try that useful addition next time.
You just need a set of these babies:
If you work on one peg at a time and leave the other strings at tension, the post will stay in place.
OP writes, "strings are expected to unwind"
Easy, just drip some glue down in there.
Cotton, PLEASE don’t make potentially destructive jokes. Not everyone reading this forum has the background knowledge to differentiate good suggestions from bad ideas.
Hi thank you for your input everyone!!
No, the post will not, and should not, just fall when all the tension is taken away. I've done this many times when doing things like adjusting the tailpiece and never had an issue.
But why loosen all four strings at the same time if you don’t have to? One at a time is safer.
"So, it means that if I loosen all the strings, the post is expected to fall, unless I belt the body up and maintain the pressure?"
I once met a "fiddler" (I'm using the word most pejoratively in this instance) in a pub session who proudly showed us how he'd prevented his sound post from falling over when he replaced strings. He had fixed it in place with a small nail through the back of the fiddle! The only thing I can say in his defense is that he had done it very accurately. Another violinist in the session, a local luthier, saw it and made some apposite remarks that I regret I am unable to repeat here ;)
One peg at a time is good advice. I wouldn't belt the body. When I want to drop a post quickly, I squeeze the c-bouts, just like the belt. Putting something in place of the bridge may help, but I can drop a post in a tuned up violin this way if I want to. The belters are just lucky. . . . so far.
Michael makes a good point about the contour of the violin and what happens if you squeeze on the C bouts.
I don't think it's a given that the sound post will fall if all strings are slack. Certainly I've never had it happen. Nevertheless, I prefer to work on one string at a time. (If all strings are slack, forget the sound post - it's a dead certainty that your bridge will fall down.)
