Testimonials

“Thanks for continuing to strive for excellence in the many services you provide. The website looks great. The more streamlined look is less distracting and I think will make navigating the sight even better!

I have been using LMII as my main wood/parts supplier for almost 5 years now. LMII not only provides excellent products, but has been a link for me to gain access to a tremendous amount of expert knowledge and instruction on acoustic guitar building. Thanks for striving so hard to connect the dots for newer luthiers like myself to be able to benefit from the hard earned experience of the pros. I am now starting on my tenth guitar and have sold 6 of them. With each build, I strive to venture to new personal ground and it comforts me to know that LMII is always there and I can depend upon you guys for whatever I need, every step of the way."

Kerfing

ITBKerfing450

Kerfing (L-R): Reverse, small, standard, triangular, and unkerfed. 

Our kerfing is a full 32 inches long
as opposed to the 16" long kerfing found elsewhere.

 

PLEASE NOTE:
We are having trouble sourcing affordable spruce from which to produce spruce kerfing. While we continue our hunt, basswood kerfing is a good substitute.

 

Kerfing (or lining) provides a gluing surface for the joining of the backs, tops, and sides. Some builders use it with the kerf facing out, so the kerfs are visible, and others glue the kerfed face to the inside hiding the kerfs. Some builders choose the same type of wood as the soundboard for the kerfing along the top and sides.

5 profiles are offered in different woods:
  • The standard profile is the most traditional for steel string guitars and modern classicals.
  • The triangular profile is used if you have a smaller instrument, or binding and purfling scheme.
  • Our reverse kerfing is designed to give added stability to the sides. By gluing the kerfed face you effectively make the side that much thicker (and therefore more rigid) with little weight or mass added. With a radiused top edge, it presents a very clean look inside the body.
  • We offer unkerfed Basswood lining for more traditional classical guitars.
  • Ukulele, dulcimer and mandolin builders can use our small square kerfing.
