How to repair Orff Instruments

I noticed that many hits to the site were searches looking for "Orff instrument repair."  I also noticed that there is not a lot of information out there about the topic and it is a topic which all music teachers need to address in their classrooms.  So, here goes.  We'll cover

  • mallet repair
  • buzzing bars
  • Annual bar maintenance
  • felt and bumper repair
  • pin repair
  • tubing repair
  • other percussion repair





Fixing the Mallets
Materials:
Elmer's wood glue
sand paper
lemon oil
linseed oil
varnish

Rough Head:  Sand the head with medium grit sand paper then fine grit.  If it still splinters, replace the mallet.

If you had a slightly shiny but unvarnished original, rub lemon oil into the mallet head.

I suggest you not varnish the mallets if they were not originally varnished. If you desire the mallet to be varnished, wipe it with linseed oil and let dry.  Dip the mallet in varnish and allow to dry.  This MUST BE DONE IN A WELL VENTILATED AREA.  DO NOT DO THIS IN SCHOOL because the fumes are dangerous.

Head Fell Off: Put a few drops of wood glue into the head of the mallet.  Insert shaft of the mallet and squish it around so that the entire surface of the head's hole is covered with glue and attached to shaft.  Let dry.  Sand any excess dried glue.


Buzzing Bars, collected from the site Making Music Fun
Materials: 
Elmer's Wood Glue

If your Orff instrument is "buzzing" when played, there are two possible reasons. The problem could be either the bar or the resonator box. Here's how you can check it out. First, move the buzzing bar to another spot on the resonator box. If the bar still buzzes in its new spot, the bar might need to be replaced. If the buzzing bar does not buzz in its new spot, then the seams on the resonator box probably have dried out. To fix this problem, run a bead of wood glue along the seams of the box and let it stand until it is dry. When the seams are dry, place the bar back in its original position and try it out.
Felt and Bumper Repair
Pin repair


Annual Bar Maintenance
Materials:
Lemon oil (Lem Oil)
soft cloth (old T-shirts are great)


This treatment is NOT for metal or Palisono bars.  This treatment is for wooden bars only. If you don't have rosewood bars, don't bother with this treatment.  Save your money and energy and buy good, rosewood barred xylophones.  Life is too short to have bad sounding Orff instruments!






Apply a bit of lemon oil to a cloth and quickly rub it into the wooden bar.  This requires loads of elbow grease.  I suggest you have this be a project at the end of a semester or year for your kids.  A drop or two of lemon oil is good for a bar.  


You can get lemon oil at the music store.  This oil is used on fret boards and fingerboards.  It's good for any hard wood conditioning.  You can also find lemon oil in vitamin stores.  Check prices for the best deal.  


Pin Repair click here for a video on how to fix pins.  It did not embed, but it's so worth watching!
Tools
  • surgical tubing
  • drill and bits
  • hammer
  • pliers
  • nails 
  • wood glue 

To access a supply of surgical tubing, you must first develop a relationship with the school nurse or a medically occupied parent (researcher, doctor, nurse, etc.)  
  1. Get several samples of thin surgical tubing from your healthcare parent
  2. pry off one of the bent nails from your instrument, note that glockenspiels have thinner nails.
  3. Take a bar from the instrument you are repairing off    
  4.  Take the tubing and bent nails to the hardware store and find nails that match the size.  Buy a box so your whole district will have access to the nails
  5. fit tubing around the nail and try to get the bar to fit over it.  In this way, you'll find the right tubing.  Bars need to be a little loose to sound.
  6. Back at your school, cut tubing and apply to the nail, sliding it to the very head.  Have only the head and 1/4 inch covered by tubing.  Use a hairdryer to shrink the tubing to the nail.
  7. dip the sharp end of the pin in glue and nail into the instrument's nail hole, allow to dry
  8. replace the bar
  9. BE AN OGRE ABOUT MAKING STUDENT LIFT BARS STRAIGHT UP.  I generally save this for the older elementary grades and treat playing these metal pin instruments as a right of passage.    
If you have flexible pins, replace them with flexible pins.  They are pretty cheap, buy a bunch and be done.  The repair I describe above is for metal pins on old instruments. 

Tubing Replacement
Surgical tubing works great and is much cheaper than buying official Orff instrument tubing, but works just as well.  Make sure that it is thin enough or the bars will bounce off the instrument and drive you nuts. 

Sand Blocks
Materials
wood glue
Upholstery tacs
course or medium grit, heavy duty sand paper
pliers or screw driver
hammer

Using the hammer, take out the old staples from the sand block. 

Repair the handle of the block by putting a few drops of wood glue into the hole and then firmly inserting the handle in the hole.  If the handle's male part is too smooth, sand it with course paper first.  Allow to dry.

 Cut a piece of sand paper to fit the block's surface and curl up around the edge.  Placing the sand paper on the block, secure it with upholstery tacs.  

Trim excess sand paper with scissors.

Here's another idea for making sand blocks.  This man puts drawer liner between the block and the paper.  You might want to try this.  

Claves

Treat claves with lem oil as your would rosewood bars (see above).  If your claves splinter, you got a cheap set.  You can either repair them as you  would a rough mallet head, or just get a more expensive pair.  The difference of price is the quality of wood used.

Thanks for the practical post! What diameter of surgical tubing do you recommend for sopranos/altos/basses?

D, Popsicle Stick and Paper Plate Kalimba!

Back to the Orffabet! Today's letter is D, the shape of the popsicle prongs on a homemade Kalimba!

Lisa Lehmberg of the University of Massachusetts, has agreed to share this portion of her book chapter. Hurray, Lisa! Let's make a Kalimba out of popsicle sticks, paper plates, and some scrap wood!
You'll need: two small, sturdy paper platesone wood block (3cm x 7cm* x 1cm) To convert to inches click here.  This block is inside the plates and keeps them from collapsing.7 cm* piece of thin plywood five flat popsicle sticks7 cm* strip of flimsy wood moldingbrads or small screws (optional)paper gluewood glue*the length is determined by the size of the paper plates. These measurements are for the structural stability of the instrument, NOT the intonation. Just eyeball or loosely measure the wood.
Glue a block of wood to a paper plate near its edge. Glue another paper plate (plates facing each other) to the original plate and the wood block. Spread glue on both the rims of the…

Liquid Ass

So we've had another school shooting. By the time I post this, we will have had a few more. The NRA and President Bone Spurs would like us to arm teachers. Shooting another human being is not natural. Killing is not natural. Self-defense only feels natural when hand to hand combat is involved. Guns, even in the heat of  battle, are abstract. Perhaps the primary reason the United States has a volunteer army instead of a drafted one is that drafted soldiers are far less likely to actually fire at the enemy when the time comes. The kill instinct has to be trained into a soldier. It isn't natural, and it takes its toll on the soul. Plus, you'll probably miss and shoot an innocent student and die anyway.

So I offer a humble alternative. Well, maybe two, but one of them is actually entertaining.

1. ALICE training. Click on this. It's helpful.
2. Liquid Ass


Developed as a joke product, Liquid Ass makes an excellent deterrent to the progress of a shooter. Shooters expect thei…

Teaching Survivors of Trauma

Dr. Nadine Burke Harris wrote a wonderful, accessible book, The Deepest Well. This post is a review of the book and a reflection of its contents.

I teach children who have been through a variety of traumas. From physical, psychological, sexual, and emotional abuse to poverty, war, transience, and neglect. I teach foster kids, kids who live in battered women's shelters or homeless shelters, kids who need backpacks of food sent home every week. 18 of my 350+ students have no risk factors for lower academic achievement.

Our principal is dedicated to a school culture that gives these children a safe, peaceful place at school. If you ever interview to teach in a high-needs school, make sure you interview them right back. Make sure they have a dynamite principal. If they don't, don't take the job. You can't save the world alone. You definitely can't help the kids if you are slowly losing your own mind. I have an awesome principal. I am safe to find out what I don't kno…
