Welcome to Home Made Resonator Boxes 101, Version 2.0

 

Updated: Oct 26, 2012


NOTICE: This CBN discussion group now has open membership. No need to get pre-approved registration to access the information contained within.


If you have ever built your 'guitar' with a home made sound box, let us know about it! Post your photos, especially any interesting construction techniques you used.


Due to my mistake of using the word "Resonator" in the name of this group, there now appears to be two groups of contributors:

1.) People wanting to discuss basic sound box construction (my intended audience):
2.) People wanting to discus building resonator cigar box guitars using metal resonators like what Old Lowe is famous for making and selling:

About This Discussion Forum

 

For those folks interested in building Resonator CBGs and Resonator Parts, please enter your posts under the Discussion Forum under either the "Resonator parts" discussion, or the "Placing the Resonator" discussion. Also be sure to check out my "Useful Links" which includes links to some interesting Reso-CBG related topics and photos (see below).

 

Most of the rest of this Discussion Forum is dedicated to people interested in discussing the various methods and styles of box building, including woodworking techniques, joinery, decorating and the like. Maybe we can have a different discussion forum for each style of box (rectangular, circular, octagonal, etc.) We'll see how the group evolves.


Useful Links:

  1. Basic Woodworking
  2. Basic Box Building
    • Project #13 "Boxtrot - Anything I Can Do (you can do)" by Mag Ruffman, the ToolGirl. In this article she shows how to make small wooden boxes complete with box joints using just a small fine toothed saw, a chisel and a few other simple hand tools to cut the box joint "fingers" and "holes". This is a very interesting article.
    • Tom Hintz & TheNewWoodworker.com - Building Basic Boxes (using power tools). He has many other articles on woodworking, too.
    • Gluing the Box Frame: Here's a diagram showing how to use two lengths of angle iron, several clamps and a web clamp to glue-up a box so that it will be nice and square. Read more about it in the Comment Wall, below.
    • Harbour Freight also sells a nice web clamp ideal for box building. They describe it as a 1" x 15 ft. Ratcheting Band Clamp, Item # 66220, and it sells for only $5.99. Here's a photo: What's nice about this web clamp is that it includes 4 corner pieces which means you don't need the two pieces of angle iron used in the box jig above.
    • Tony Hyman's Cigar History Museum - Types of Cigar Boxes has a lot of interesting photos of old cigar boxes that makes for some interesting viewing & reading, especially if you decide you want to decorate you home- made wooden box like an old cigar box.
  3. Advanced Box Building
    • Testing a box for bridge placement - a link to an interesting Cigar Box Nation discussion in the Super Advanced Cigar Box Building group that was started by a question posed by John Maw. The best solution was the idea of building a diddly bow in which to test your boxes for sound quality and optimal bridge placement. [Fixed link, 9/19/2011]
    • Here's a challenging box design ideal for a real cool Cigar Box Guitar:
    • Sound boxes don't have to be square or rectangular.They can have any number of sides. But remember that the corner joints must be cut at an angle appropriate to the number of sides the box will have. Here is a summary of that data:
      Num. of Sides = Corner Angles
      3 sided = 60 degrees
      4 sided = 45 degrees
      5 sided = 36 degrees
      6 sided = 30 degrees
      7 sided = 25.71 degrees (26 is okay)
      8 sided = 22.5 degrees
      9 sided = 20 degrees
      10 sided = 18 degrees
      11 sided = 16.36 degrees (16 is okay)
      12 sided = 15 degrees
      15 sided = 12 degrees
      16 sided = 11.25 degrees (11 is okay)

      Much above 16 sides and you may as well go with a circle. What ever number of sides you decide upon, the angle size can always be calculated by dividing 180 by the number of sides you want to have.
    • How to bend wood to form rounded sound boxes? Check out these two web pages set up by Jim Varnum: "Travel Guitar"and "Appalachian Mountain Fiddle". Both articles describe in fair detail the process of bending wood by soaking them in near boiling water for 30 to 45 minutes.
    • Another good source of information about bending wood is the Veritas® Steam-Bending Instruction Booklet, which is a free download - just click on their link "View as PDF" near the bottom of the page.
    • The folks at buildyourguitar.com have a very extensive list of links for folks interested in building guitars. I'm sure there are a lot of techniques explained in these links that are applicable to building box guitars.

just found this group---I thought I would share this new build in progress---cedar frame with 1/4" maple plywood top and bottom, 10" dog bowl, maple neck, mahogany fretboard, 4-string "banjo"

Comment by Rand Moore on January 10, 2013 at 3:50pm

Hi Mark

Yeah, some builders seem to prefer to bolt (screw) everything together rather than to use a lot of glue. I believe bairfoot cajun is one of the leading proponents of this building method, and he is known for some very original builds. The other folks who build this way tend to be electronic CBG builders who do it so they can access the "electronics" inside their box fairly easily should some problem arise.

I prefer glue almost all of the time, but as I build more electrics I may change my mind and figure a way to access the electronics in the box.

You seem to have access to a nice wood working shop (with the table saw). I live in a flat (condo) so, I don't have the luxury of having a garage or shed that I can convert into a wood working shop. I still building on my desk which used to be my "guest room/home office", but is now my "wood shop". My wife won't allow me to buy a table saw or drill press, etc. So, I make do with hand tools and my electric hand drill.

Those boxes look like a good start for a couple of home-made box guitars. Good luck on your projects. Let us know how they turn out.

-Rand.

Heres a couple of photos of my latest boxes  builds 7&8 and possible 9 I use wood recscued from the wood recycling skip in work so far this has  been mostly mahoghany/sapele or parana pine my wood working skills are not that good so the boxes tend to be" screwed & glued" The sound deck and neck is usually bolted to the box frame using threaded inserts which means the deck can be readily taken off and on andtighten back up again without fear them getting slack

That's some really nice wood working there, Habanera Hal. Looks like you are well on your way to becoming a real luthier.

Comment by wormil on July 20, 2012 at 2:42am

I'll be using fretwire on my current (3rd) build because the neck is too narrow (1") for copper wire. I'm not sure whether to use small or medium fretwire though.

During vacation I stopped at a Dulcimer shop and goofed around with a McNally Strumstick and it played so much nicer than my first CBG; not necessarily because of the frets, it was just better built all around. Now that I have some idea of what I'm doing, I'm really trying to make this new instrument a real player... mahogany neck, zebra wood fretboard, solid wood box, and a 25" scale. And really paying attention to the details of construction. Going to stick with the copper wire side markers though, love those and simple to install.

Comment by Rand Moore on July 20, 2012 at 1:21am
Hi Wormil,
Your first little uke turned out very nicely. Hope is sounds good. Waiting to see the Video. I like the idea of your copper wire fret markers on the side of the neck. Maybe I'll try that on my next chromatically fretted instrument. It also seems your 14 gauge copper wire fretting is attracting a following, but I think I'm too spoiled by the ease of installing real fret wires to go back and try yet another alternate fretting technique. I did one CBG with bailing wire, which is probably stiffer and slightly more difficult to work with than copper, but basically the same technique. After doing the one, I switched to cut nail frets (glued in with 2-part epoxy), and built several of those before scoring some real fret wire, which I've used ever since (except one which used cut skewers... At a time when I had run out of real fret wire). Those bailing wire, cut nail and tie-wrap (zip tie) alternate fretting methods were done when I was first getting into CBG making just a 2 or 3 years ago. At that time I felt a bit intimidated by the idea of using real fret wire, but I found those fears unwarranted. I think most builder start off with one or more alternate fretting methods before they settle on using real fret wire. So, maybe consider using them on your next build.

Other than that, your build is a great first build. Keep up the good work!

-Rand

Every part built by me (except for strings and tuning pegs of course).

Comment by Rand Moore on October 30, 2011 at 2:13am

Hi Michael,

That's an interesting set of photos and an interesting way to attach the neck to the sound-box. But, I suspect there are easier ways to attach a neck to the box. You might want to check out some of the build photos on Cigar Box Nation (use the search box at the top-right corner of each page and use words like "neck attachment" for the search criteria. What do you see as the main benefits of building a CBG using this V-cut neck attachment technique? My main concerns would be to avoid using electric tools (other than a drill). So far, it looks like your technique could be done using simple hand tools. Well, let us know how your project turns out. If you plan to add many more photos, you might want to start a discussion in the section above, perhaps being general enough in scope to allow other techniques to be discussed -- like "Neck Attachment Techniques".

-Rand.
