If you have done your job in making high quality linings, this section will be a breeze for you.
Are the sides shaped or cut down and sanded to receive the arched back according to the respective Side Template?
Installing the Lining For The Top and Back Plates:
Preparation is the key word here and you should get all of your ducks in a row before you begin to glue. Also, check the sides for squareness by fitting them down in the Inside Form. Put the Spreader Jacks in place and look at the joint as it touches the bottom of the form. Mark any areas that may be high and sand these down with a Large Surface Sander. Repeat this process until the fit is perfect.
Dry Fit The Linings:
First, dry fit the first lining. Start tight against the tail block. Install a clamp as often as you need to keep the lining tight against the side. When you get to the head block, trim as close as you can with a Japanese Pull Saw. Now dry fit the other side in a similar way.
Clean and Prep The Woods:
Do any final sanding you need to do before installing the linings. If you haven’t already, clean the exotic wood sides with Acetone. Do final sanding on the side wood.
Assemble the Clamps:
There are two types of clamps that I would recommend for the lining. One would be small metal or resin spring clamps. You will need about 30 to 36 per side. The other is a homemade clamp made from wooden spring clothes pins and rubber bands wrapped around the jaws. You will need about 60 of each of these per side.
Spread the glue thinly on the glue surface of the lining only. Do not spread glue on the guitar side as this is too time consuming and too much of a mess to clean up. Spread out the glue with a flat piece of wood veneer so it is spread evenly over the entire surface.
Start to Clamp:
Start at the Tail Block end and line the lining up with the side. I like to glue the lining just a bit above the side. About 1/16″ or so. This give me a little extra sanding area to work with on the sides. Loosely clamp the lining around the sides to that the glue won’t mess up anything.
Place the clamps shoulder to shoulder and work your way around the entire side. Make sure things are tight and even every few clamps. If you have a stubborn area where the lining is not tight, use a small 1″ C clamp to tighten it up. Be sure to use a caul on the C clamp jaws.
Note: If you plan to install an Acoustic Guitar Top with a “free floating top” follow the procedure in the Installing Classical Guitar Linings Section.
