Q: What do I do if I blow out a reed?

A: If you are careful, with needle-nosed pliers you can pull out the soft metal plug that holds the reed to the plate. You may have to start this by pushing the plug out from the underside of the plate. A jeweler's hammer and awl can be used for pushing. The plug should come off with the reed attached. Pull out your blown reed the same way. You can transplant the assembly--plug and reed--to another plate by pressing the plug into the new plate. Press the replacement reed into place by hand, then use the tip of the pliers to make sure that the reed is flush with the plate--do this without squeezing the plug.

Once you have it in place, gently crush the plug from above and below the plate with the pliers. This causes it to expand and grip the plate. Finally, make sure that the reed tip rests above but close enough to the plate for vibration to work. I've repaired several harps this way, always replacing reeds with the same reed from a spare-parts harp by the same manufacturer. Using a different reed and cutting or shaving it down to size will almost always fail.

Downsides: This will typically last half as long as the original reed. The replacement reed will have slightly different tonal qualities. It's easy to mash the plug in wrong. I didn't really get it right until my third repair. -- "BLOWN REEDS -- how to repair" 7 Jan 93 MB


>From " Replacing bad reeds" 7 Jan 93 DA:

Don't throw those away! You can replace the individual reed if you are handy with small tools and can re-tune reeds with an electronic tuner.

First punch out the bad reed rivet from the bottom. Then select a reed from your "parts harp" to replace it with. The reed you replace it with should be the same tone or lower than the original reed and the same length or longer so that you can tune it up by filing or scraping on the free end. (If the replacement is higher in frequency, you have to file on the rivet end to lower the pitch and this weakens the reed considerably.)

The replacement reed and rivet will stay together as you punch the rivet out with an awl or pin punch. Take this reed to the reed plate you are replacing and line it up with the slot in the plate and the hole for the rivet. (I use scotch tape to keep everything in alignment while I tap the rivet into the hole with a small hammer and set the rivet by light tapping until everything is solid.) Don't tap too much or you will flatten the rivet and the reed will be loose.

You now have a reed attached to the reed plate of the harp in question, but the fun is about to begin. First adjust the alignment of the reed by holding the reed plate up to the light and gently twisting on the rivet end of the reed until you see light through the slot on both sides of the reed.

If the replacement reed is too long, just get some small diagonal cutters or a flat (not curved) set of toe nail clippers and take off a little from the length until the reed will swing through the slot. Work slowly here because if you take too much, the reed will sound very airy.

Test the reed by plucking it with a small knife or screwdriver. If it doesn't swing freely, look for problems like improper alignment or a bent rivet which doesn't center the reed in the slot.

Now set the "action" of the reed to about 1 to 2 thicknesses of the reed from the reed plate. If this offset is too much, it will be hard to get the reed started. If the offset is too little, the reed may not start vibrating when you blow.

You now have a new reed installed which will sound when you blow into the harp, but it is probably a wrong note especially if you used a lower tone reed than the original, but this too can be fixed. Get out your electronic tuner and reed files/scrapers and go to work. I have been able to tune reeds up by more than 2 whole steps and get a reliable and good sounding tone. This takes practice.

I have found that the new kit from Lee Oskar contains some helpful advice and a new tool which I hadn't used before and which I now find indispensable in tuning reeds, the Reed Scraper. This tool is a scalpel like chisel which is used to scrape material from the reed tip. Using this tool, I have been able to remove material evenly from the reeds and get a very smooth finish. Again, this takes patience but the reward is yet to come.

When you have that new reed tuned up. Why stop there? I find that I really enjoy playing on a harp that is in tune so I continue to check and re-tune all the reeds that need it. Have you ever wondered why those new harps sound so good right out of the box? For me, the reason was tuning. When you get the whole thing in tune with itself, it will sound like new.

The best part of this is that I have done this to 4 of my better harps, 2 Golden Melodies and 2 Meisterklasses and the repairs are holding up very well. In fact, I can't tell which reeds I replaced unless I open the covers and look at the rivet and scrape marks on the reeds.

Don't avoid this because you think it might be hard. Folks have been telling me this was hard for years, but when I tried it, I was successful my first 4 out of 4 tries. And... I'm not into hock to Mr. Hohner for 4 new harps -- " Replacing bad reeds" 7 Jan 93 DA


From "RE; ReedMods" 4 Jan 94 JE:

If they imply you should throw away your broken harps - DON'T. One of these days you'll learn how to repair them and/or pirate parts from one to fix another. Throw them in a "bone box" and keep them for a rainy day.

>From reading some of the postings already I see that I actually have to >Break In my new Harp...Also, on the Lee Oscar, I understand that they >aren't usually in tune to begin with and modifications are necessary. >(I have to become a technician too 8-( ) ahhhh).

Lots of pros and cons on this - I don't break in my harps - probably because I'm a relatively "soft" player - If I need loud I let the mic do the work. But in general it is probably a good idea to break them in.

I can't comment on out of tune harps - I have never found a new harp to be seriously out of tune. What does that say about my ear? Of course you have to realize too - I am a government worker. I have had new harps in need of some tweaking to improve response.


>As a beginner I'm missing a whack of tools in my tool kit. HOW DOES ONE >MODIFY the reeds to give it the proper tone?

I can recommend two excellent books - One is just recently available from Dick Gardner. I haven't seen this one yet but my co-editor gives it a thumbs up! - send $10.00 to Dick at...

7024 Jocelyn Ave. S. Cottage Grove, MN 55016-3640 (612) 458-1193

The other is from Dr. Harp (aka BSHC's Richard Smith) Write...

Buckeye State Harmonica Club 4532 Benderton Ct. Columbus, OH 43220

Oh, this one is $5.00 -- I recommend both. If you only buy one, get Gardner's - the humor alone is worth it.

TOOLS-- Lee Oskar sells a nifty little repair kit in a roll up pouch for around $25 list. It is designed for L. O. harps - so it only contains a Phillips screwdriver. Add a small flat head and you're equipped to do minor repairs - read adjustment, tuning. etc. A how to sheet is included.

F & R Farrell Co. - has various harmonica repair tools. call 1-800-438-3543 or 1-800-438-3544 & ask for a catalog.

Finally, most people who get half way serious about harmonica repair end up populating their own tool kits with stock tools and sometimes homemade tools.

Here are some things to look for... a) Precision screwdrivers - flat & Phillips. b) A GOOD set of forceps with angled or curved tips. c) Fine file d) Sharp scraping tool (razor blade, Exacto, etc.) e) Soft tooth brush f) 91% Isopropyl alcohol g) Feeler gauge material or thin metal strip h) Tooth picks i) Soda straw (cut to approx. 2" - makes a nice reed setting tool). j) Small pliers k) Light weight hammer. l) Ask your dentist if he will save some old dental tools for you.

Now dig up an old harmonica (one you don't care about) and go to it. Hint for #1 project - Retune the draw 5 reed up 1/2 step (F to F# on a C harp). You do this by scraping or filing small amounts off the free end of the reed. Use the gauge material to slide under the reed for support. File/Scrape a little at a time and test often. You will probably have to adjust the reed set after you get the pitch right. If you have any luck at all you will have a quick and dirty country tuned harp.

That's just a start - I'm sure you'll get more ideas from this list and from the repair manuals mentioned above. -- "RE; ReedMods" 4 Jan 94 JE
