Welcome to Home Made Resonator Boxes 101, Version 2.0

Updated: May 15, 2015

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.

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.
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.
- Block Rim Construction is a series of YouTube videos produced by Richard Brown (aka "bordertownbrown") detailing how to build round bodies as for banjos and similar instruments. Many of the techniques he shows are also applicable to the regular polygonal sound boxes described above. There are 7 or 8 videos and all the video files are named "block rim video partX.mp4" where "X" is the part number between 1 and 8. Use the search feature on the YouTube website to search for the additional videos of the series.
- 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.
- Also, on the Friends of the Mountain Dulcimer (FOTMD) website, there's a discussion entitled "American Cittern (Strummer) Building Discussions " which details how one builder (Bobby Ratliff) builds his round bodied stick dulcimers. It includes photos of the form he uses and mentions that he uses a propane torch to heat and bend his red oak sides; rather than soaking them in steam or water).
- 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.

Comment by Thomas "Duck" Petry on June 24, 2014 at 6:42am: I have done a couple of home printed labels on regular paper on CBGs that I finished with lacquer. Sprayed a wet coat of lacquer on the box and paper and stuck it to the box. after it all dries a sprayed a final coat of lacquer over it to seal the edges in. Worked well.

Comment by Robert Dawkins on June 24, 2014 at 5:17am: I just did a Google search last night on that very thing (Mod Podge), and learned that decoupage methods have changed somewhat from when I was a kid in school.

I typically do my own artwork, and am looking for a way to transfer the imagery to the box, but I want it to be a "thin" transfer (kind of like water-slide), and not have the thickness of the art paper to deal with. I'll try the Mod Podge method on some photocopies of my artwork on a scrap box, and see how it works.

Comment by TN Twang on June 24, 2014 at 5:08am: I like the Avery label idea for a quick highlight, but decoupage ain't all that hard. Use "Mod Podge." I know it's a stupid name, but it's from a company in Georgia that seems to OWN decoupage nowadays.

Go to Hobby Lobby or Michael's and buy a jar of "Mod Podge" and a can of spray laquer like artists use to protect charcoal drawings. Lacquer your label to make it not absorb moisture. Then spread the Mod Podge on back of the label and roll it out flat with a glass jar (Mod Podge comes in a round jar!). Get it good and flat so it won't peel.

Spread more of the Mod Podge over the top of the label to protect it. Let it dry and then varnish the whole sound board (or headstock or whatever) for a consistent outer surface.

In a different vein, note that 19th and early 20th-century builders steamed off the paper and threw it away. It was the WOOD that they valued--not the fancy lithography,

Comment by Redbelly on June 24, 2014 at 1:00am: You Can Buy Cigar Box Lables on ebay. They are very good.

Comment by Robert Dawkins on June 23, 2014 at 1:26pm: That's a great idea, Gary...I've got some artwork I want to use on my first CBG, but wasn't sure the best way to do it, but this hits the nail on the head; decoupage is a lost art, and way too messy for me to want to get into!

Comment by gary sheldon on June 23, 2014 at 12:22pm: Cigar Box Art:

I love the graphics and artwork on these cigar boxes. But, I have taken to making my own "fake" boxes so I can make them larger and select the wood myself.

Today, I bit the bullet and spent $30 on 25 Avery shipping labels. These are clear 8 1/2 X 11 with a backing.

I scan the artwork, print on the label, remove the backing, and self stick it to my box.

Here is my first try:

Comment by gary sheldon on June 23, 2014 at 5:31am: Make that 1 1/2 mile from the ferry.

Comment by gary sheldon on June 23, 2014 at 5:30am: Rand,

Yes, Marin County opted out of BART when it was first proposed, so our transportation is Golden Gate Transid and ferries.

I am about 1/12 mi from the ferry terminal. It would be lots of walking.

Anyway, maybe I could meet you at MacBeaths sometime, then I could bring you over here and then drop you off at some transportation. There is a ferry here and one in Larkspur Landing.

I am off most days, but have some classes at night. I take salsa dancing and Tango. Occasionally I have work doing home repairs.

Comment by Rand Moore on June 23, 2014 at 4:38am: Hi Gary,

Sausalito. Yeah, that's not a BART destination. Hmm... Isn't there a ferry service nearby? I could BART to the Embarcaderro and walk to where? The Ferry Building? and catch the Ferry to Sausalito.

Yeah, I haven't owned a car since I moved to China; it's not worth having one if you are only going to use it 2 or 3 months a year. I can sometimes borrow a car, but usually for local driving. However, I will be helping them (my wife's sister and husband) by driving their kids to San Diego and back this week, so maybe I'll have earned enough good credit for another "intra-regional" trip. They are already on vacation (we're baby sitting) and they will meet us there and we'll be going to the Zoo and Sea World, etc. They'll be flying back as well. So, it's kind of a working vacation for me and my wife, but sometimes you have to do this kind of thing to stay in grace with the in-laws. My "flying" funds are depleted flying from China to the States and back each year.

-Rand.
