Tim - thanks for sharing all the photos. I've tinkered with building a few electric guitars, and hope to make the move up to an acoustic in the next year or so.

Two photos caught my eye - the body mold pic - it looks as though the turnbuckles are "loose" - held in place by the compression from the sides?

And the pic showing the top bracing ... the double brace on the neck side of the soundhole - did you follow an established bracing layout, or is the pattern your own? I'm wondering why the two braces so close together - my understanding is that the less bracing (within reason), the more volume.

Again - nice work ... could probably ask a hundred questions

Hi Carl, thanks for commenting.

The turnbuckles hold the sides firmly into the body mold until the back and soundboard are glued on. I take everything out via the soundhole after the top is attached.

Concerning the bracing. the body shape and bracing is of my design and has evolved to this for this body shape. The double brace you are referring is called the upper transverse brace or UTB and needs to be very strong. The string pull will force the body down under the fingerboard extension. The double brace is a long story but I'm not the only one taking this approach, Jim Olson is a very notable builder doing something similar. This part of the top contributes almost nil to sound production, it is the part below the soundhole that really matters.

Hi Tim,

I love the design and details on this instrument and I can imagine the tone is equal to the esthetic given the rosewood/spruce combination.

Like Carl, I too was curious about the double bracing near the sound hole...I hope you achieve what you are seeking with that design and I applaud your ingenuity and creativity.

The instrument is beautiful and if I were to see this guitar on the wall of my favorite guitar shop, it would be the first one I would sample!

Congratulations and kindest regards, Ken.

Thanks Ken,

That's alot of complements!

I've have taken this very, even obsessively serious since my first. I am really pleased with the tone of my last 2 guitars. If you are interested there are 4 sound samples of this guitar at

I wish I had 1/10th of your talent.

That's beautiful work. I just happened to have toured the Martin Guitar factory the other day. While they have automated a lot of steps, there is still a fair amount of careful hand work. You've probably only shown 1/4 of the many steps that went into it. Great job--I want to play the darn thing!

Posted By: hank     [01/18/2015]
that finish is flawless - what did you use?

Posted By: tim minkkinen     [01/19/2015]
Thanks Tony, I've never toured a big factory and would certainly enjoy it. Yes there are many steps. One of the first thing I did after 2 or 3 guitars was list the steps in an outline. It really helps keep my head straight and not forget any of the really important angles or measurements.

Thanks Hank, the finish is ICA 5051 polyester, a fantastic product that enables the user a durable, thin, light weight guitar finish that is relatively easy to use and polishes very well. I have also used shellac and precat lacquer, but the poly definitely is easier and more durable and faster. Tim

What sanding grids steps and polishing did you take to bring such beauty in the mirror imagine.

FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator
    (return to top).

    Carefully review your message before clicking on the "Send Message" button - you will not be able to revise the message once it has been sent.

    You will be notified of responses to the message(s) you posted via email. Be sure to enter your email address correctly.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
