A Brief History of Finishes on American Guitars, by Jeff Jewitt
Finishes used on fretted instruments like guitars, lutes, and violins play a key role in the performance and quality of the instrument. While there are countless debates on whether finishes detract or add to the sound quality, the main purpose of a finish is to protect the instrument and add to its aesthetic appeal. Without finish, a wooden instrument would react more quickly to changes in humidity and eventually self-destruct. Plus, a finish deepens the color of the wood, and adds depth and luster which makes it visually more appealing and more playable.

The Major Advantages of Hide Glue
Hide glue is water-soluble, non-toxic, and forms strong, durable bonds that are easily reversible, making it ideal for repairs. Despite its thermal limitations and short open time, it is preferred for its ability to create precise joints, its capacity to be reheated and reused, and its compatibility with traditional woodworking techniques. Different gram strengths of hide glue cater to specific applications, with higher strengths favored for high-stress joints, especially in stringed instruments.

Transitional Arm Bevel Construction Notes, by Rolando Padron
These notes are just my personal observations that made making my second arm bevel easier than the first. It also incorporates some of the comments Kent made in the video as alternatives and also some that were so quick and subtle, that it is possible to not catch them while watching the video and appreciate the benefit of applying his comments in your bevel design. Please note, I want to respect Kent’s hard work on his video, and I am therefore not including design parameters and dimensions, as these are included on his dvd, and I highly recommend it to any who want to learn how to execute it into their builds.

Well Oiled with Adamson
Discover the art of achieving a flawless wood finish with Stewart Adamson, winner of the Henry Flack award for best finish at the Woodworker Show. In this detailed guide, Adamson demystifies oil finishing, presenting it as a simple yet highly effective alternative to traditional methods like French polish and spray finishes. His approach, perfected through years of crafting classical guitars, lutes, and balalaikas, addresses common finishing challenges and provides a step-by-step procedure adaptable to various woodworking projects. The article emphasizes the importance of meticulous surface preparation utilizing advanced abrasives like 'Micromesh,' originally developed for the aerospace industry, to yield ultra-smooth, scratch-free surfaces. Adamson also highlights the aesthetic benefits of oil finishes, such as a natural satin sheen and easy maintenance. Whether you're working on a delicate musical instrument or any woodworking piece, this method promises exceptional results without the hassle of weather-dependent conditions or complex setups.
UV Cured Finishing for Guitars, by Brian Howard
As a lifelong wood finisher and former contractor for small guitarmakers across North America, I've honed my skills with various sprayed finish systems such as Conversion Varnish, Epoxy Urethane, and Nitro. Yet, transitioning to UV-cured finishes posed new challenges despite my experience. Anticipating a shift in industry standards, where shops may soon rely solely on CA repairs and water-based systems (which are suboptimal for guitars) or transition to UV curing, I present this guide to navigating high-quality and suitably thin UV-cured guitar finishes.

The Heretic's Guide to Alternative Lutherie Woods, by John Calkin
Why do we even need alternative wood species for musical instruments? That's a perfectly valid question, and the answer is that we don't. Rosewood, mahogany and maple have served us well for centuries , we know what to expect of them, and our customers have already come to accept them as trustworthy and will pay for them. So why look further?
