Cello sound post extractor ?


~ Ben Conover

Recommended Posts

I bought that type for violin and cello over 20 years ago and find them very useful.  And I made one for basses after I got tired of shaking bassses upside down above my head.

I also have both, and find them very useful. It saves needing to push or roll the post around until the stab mark is accessible.

Try one of these. I have one, and the head diameter is about 9mm. I don't have any full size cellos around, but it should fit. It's a tiny bit too big to go through the f slot of a 1/8 cello. but it will fit through the lower eye.

Try one of these...

 

I used to use one of those because it's shown in the Weisshaar book, but I abandoned it in favor of the one linked to in the original post.  The one you show is great for fishing bolts out of engines, but a cello sound post retriever works much better for retrieving cello sound posts.

Below - made from one piece of "SilValoy - Excel 15" brazing rod.  Comes 28 sticks to a pack, so you might ask a local welder for a piece as they are 15% silver so you may have to pay a buck or two.   Or try another type of brazing rod, but this one works super. Cut one 20" stick  into two pieces, bent to shape the ends, ground the tips a bit to ensure it wraps around the post, then solder it about 3" back to give it some flexibility.  Its like spring steel, .050" thick and 1/8" wide.  Made a perfect extractor.  Of course, you could just order one from Howard Core for $12.  But its more fun to make my own.

For cellos I use a laparoscopic grasper like this one. The type of jaws that bend inward at the tip give a good grip on round stock. They're also handy anytime you need to pick up something inside the instrument. I've actually managed to pick up an endpin that fell into the body and maneuver it back out the hole in the plug without having to take the strings off.

You can just use 20cm needle file.

 

Screw the tip of the file into the notch of the loosened sound post. You will have total control when you get the sound post out without any worry it will fall off. Make sure you unscrew the tip of the the file when taking it out of the sound post - or you will break it. Ask how I know it :rolleyes:

Ok, so that's two more Irish makers posting here, no name. 

 

Ben, Caoimhín is my name... ;)

 

(I did actually ask the admins if I could change it to the English version of my full name cos for some reason my account wouldn't let me, but I never heard back)

I have one of these for violin and it's very useful, if a little bit crude.

Anyone found a 'better' one for Cello ?

OOOOPS,  I SEE THAT OTHERS BEAT ME TO IT.    I WILL LEAVE WHAT I WROTE AS A VOTE FOR IT.

 

 

The autoparts stores sell one that is a flexible steel shaft of wound wire.  Inside are four springy things that terminate into four claws at the business end and a push-button at the other.  One can cut off two of the spring-fingers and it works great.  (The autoparts connection is that it is intended to retrieve screws dropped into engine cases,  I assume.)  And it is cheaper than those shown.
