Frequently Asked Questions regarding Tedrow Concertinas

Q:  How long did it take you to learn to build concertinas?

A:  Honestly, I am still learning!  Most of the instruments that I build have subtle differences in the dimensions.  I pay  close attention to small details in construction and  am willing to go back to the drawing board at the drop of a hat, or screw or pad or hammer or tongs.  I built my first musical instrument, a banjo in high school in the late 60's.  So the answer is.....over 30 years?  If you would like to have some additional background on me or the shop look here



Q: Do you build those concertinas from a kit?

A:  No, there are no concertina “kits” available.  Each instrument begins with properly dried woods selected for their utility and appearance.  The wood is resawn and dimensioned here in the shop, as evidenced by the copious saw dust in the shop. 



Q: ”Do you use a laser to cut those  fancy ends?”

A:   I believe I’ll take that as a compliment, but no,  I cut the  all my concertina ends by hand with a  Hegner  scroll saw.  And yes, it does take a long time as each cut requires the saw blade to be removed and replaced through a small hole in the top.  Hand cut fretwork requires many many hours of practice, but it is worth the effort when it produces a little piece of art.



Q: How long does it take you to make a concertina?

A:  One week (without distractions!) for a concertina with traditional Italian reeds.  Much (much!) longer for an instrument with traditional English reeds.



Q: Can you make a concertina from my wood?  I have a piece of my grandmothers cupboard.

A:  Oh yes.  I can almost always find a way to incorporate your family history into an instrument for you.




Q How do you make the bellows?

A:   Like this I build traditional cut card bellows of  leather and a neutral Ph cotton ragboard. That means each individual trapezoid is hinged with  linen and leather.  Bellows properly built in this manner play beautifully when brand new and will retain their utility for one hundred years. Other than the obvious financial benefit, I can see no advantage building with a contiguously folded cardboard.


 
Q: Do you make all those little parts inside the concertina?

A:   I make the springs by hand with a lovely little spring making jig that I built.  The buttons are turned by hand on a miniature lathe.  English felt bushings are cut and installed by hand. The levers and posts are hand riveted, measured and installed by hand.


Q: What kind of reeds do you use on your concertinas.

A:  I use traditional Italian steel reeds for my Standard Tedrow concertinas.  I build traditional English style reeds  for custom instruments.


Q: How do you tune a reed?

A:  reeds and reedframes are carefully hand profiled to a desired pitch and  fine tuned using hard steel files and  a stroboscope.   That is a succinct description of a complicated and  lengthy process.   It easily takes as much time to build a set of reeds as the entire balance of the concertina!
