Assembly Instructions
A NOTE ABOUT GLUE
We recommend assembling this kit with standard woodworker’s glue (such as Elmer’s Carpenters Glue or Titebond Wood Glue). Don’t use Hotmelt glue, Superglue, 5-minute Epoxy, or the plain white School Glue for assembling the major wood parts -- they are not strong enough for a musical instrument. There is no need to look for any special violin-maker’s adhesive. You may, however, see epoxy or superglue recommended occasionally for installing non-wood parts.
Every time you use wood glue on this project, it is wise to have a damp rag handy for cleaning up afterwards. It is always best to scrub away any excess glue that squeezes out of the joints before it dries, especially on the outside of the instrument. Keep your hands and workbench as clean as possible too. Glue smudges will show up vividly on the finished instrument.
ASSEMBLY INSTRUCTIONS
_____1. CAUTION: PLEASE DO NOT OPEN THE SEALED PLASTIC BAG CONTAINING THE FRONT AND BACK PANELS UNTIL YOU REACH STEP #14. These two parts need to be kept very dry until you glue the braces on them. Check over your kit parts to make sure you find everything listed (see fig. 1 above). Contact us right away if you are missing anything so we can rectify the problem without causing too much delay for you. We also recommend checking off each step in the directions as you finish it. You might be skipping forward to another part of the assembly while waiting for something to dry, and it helps to keep track of where you left off.
2.
GLUING THE BODY FRAME
It is smart to skim through the entire directions before beginning, just to get an overview of the project. You may need to gather more tools or purchase a few optional decorations or accessories to enhance the finished instrument. Now is a good time to make those plans so you can avoid delays later. Here are a few of the small items you’ll want to have on hand:
sharp chisel wire cutter 8 spring clamps 2 long-reach clamps for braces masking tape (blue) clothes pins 8 small c-clamps 40 ft bungee cord (3/16” dia) carpet tape razor knife triangle file router with flush-trim & inlay bits straight-edge 6” rat tail file flat mill file wood filler (mahogany color)
_____2. You will find it very helpful to make yourself a perfectly flat work surface out of 3/4” thick plywood or particle board for use as a flat clamping pad under the body of the instrument. If you cut it about 1” larger than the shape of the soundboard, you will be able to easily fit clamps all the way around the perimeter of the instrument (fig 2a).

Clamping Board
3/4” thick
perfectly f lat
about 22” X 28”
Another idea that works well is to use a rectangular piece about 22” X 28” (fig 2b) so you can clamp with bungee cords, as shown in steps 21 and 31. We use both types, as you will see in various photos. Just make sure the clamping pads are good and flat.

Fig 2b
CAUTION: IT IS POSSIBLE TO ASSEMBLE THE FRAME PARTS U PSIDE DOWN OR BACKWARDS!
_____3. Carefully arrange the side pieces, corner blocks, heel block and tail block on your plywood clamping board to see how they fit together (Fig 3).
CAUTION: Orient all parts so the front edges face down­ward on your flat clamping board. Notice that we have marked each side piece, and heel & tail blocks, indicating the proper orientation.
All front edges are marked “SB” for soundboard, and the back edges are marked “B”.
The corner blocks do not have a front or back, but they are numbered C-1 or C-2 to fit the corners with those numbers. Please take the time to study this carefully so your parts will fit properly.
ORIENT ALL PARTS WITH FRONT ED GES FACING DOWN

_____4. Begin by gluing and clamp­ing the four corner blocks to the two side ribs, taking care to orient them at the correct ends, as printed on the wood (each side rib gets a C1 at one end and a C2 at the other end).
CAUTION: The larger part of the corner blocks will face the inside of the body, as shown in fig 3. Don’t
Fig 4a
glue them to the outside of the sides!
Clamping wedges are provided to help compensate for the angles of the parts, as shown in fig 4b. HINT: If you cover the wedges with Scotch tape, they won’t get stuck to the other parts when clamped.
Use either spring clamps or small c-clamps for this step (fig 4c), mak­ing sure the parts are fully seated together and flat on the edges. Use a wet rag to clean off excess glue that squeezes out. This helps you see the joints clearly, as well as prevent messy glue spots on the instrument.

QUESTION
Have you checked to make sure you are still gluing the parts in the correct positions? If you  nd a corner block glued to the wrong end of a rib, you’ll need to correct it now, before proceeding further. You can so en the dried glue by getting the seam wet to allow the parts to be separated without breaking anything. Be patient with this process. It may take 10-20 minutes for water to penetrate far enough into the seam to so en the glue.
_____5. While the corner blocks are drying, you can work on the tail end of the body. Use tape to hold the tail ribs together as shown in fig 5a.
Find the center of the tail block and mark it clearly (fig 5b).
Smear glue on the flat face of the tail block (fig 5c) and place it inside the seam, as shown in fig 5d. Find a scrap of wood to use as a clamping pad for the outside of the joint, and add clamps, making sure the block is oriented correctly and nicely centered on the seam (fig 5e).
IMPORTANT: Make sure the free ends of the tail ribs can be pushed down to the work surface (fig 5e). If not, then you may have to release the clamps and slide the parts into better alignment.

_____6. Now you can move to the heel end of the instrument. Mark the center of the heel block, on the end marked “Back” (fig 6a).
Glue this heel block to one heel rib for now, aligning it to the centerline, as shown in fig 6b.
Clean up excess glue with a wet rag, as usual.
Fig 5d Fig 5e
IMPORTANT: Leave the other heel rib for later. That will be the last step in clos­ing the frame.

_____7. When the corner blocks are dry, you can re­move the clamps and glue the C2 blocks to the tail ribs, as shown in fig 7a.
Make sure you can press the C1 corner blocks down

against the work surface when the side ribs are clamped to the tail ribs. This

ensures a flat frame for glu­ing the front (soundboard) in place later.

the open C1 corner, as shown in fig 7b. Leave clamps in place for several hours to make sure the glue has cured to full strength.
PAUSE AND DOUBLE-CHECK
Before going further, double-check to make sure your parts are still in the correct positions. Do you see “Back” written on the same edge of all the parts around the frame? If you find something oriented upside-down or back­wards, you’ll need to correct it now, before proceeding further. You can soften the dried glue by getting the seam wet to allow the parts to be separated without breaking anything. If the glue is fully cured, it may take 10-20 min­utes for water to penetrate far enough into the seam to soften the adhesive.
_____8. When the four corner joints have dried fully, use tape to pull the last heel rib into place at the heel block as shown in fig 8a.
Remove the tape so you can apply glue, and then tape the parts together again as you clamp this last joint together permanently (fig 8b).
Fig 8a
_____9. Once the frame is closed and the glue is dry, you can install the long spacer block between the heel and tail blocks as shown in fig 9. This piece will be removed later, but you need it now to hold the frame to the correct size. Note that the ends of the spacer will fit into the pre-cut grooves of the heel and tail blocks. Use a clamp at each end to make sure the heel and tail blocks are held firmly in alignment.

_____10. Flip the instrument over (soundboard edge up) so you can fit kerfing inside the frame. Cut a length of kerfing to fit between the corners and blocks inside each rib (fig 10a & 10b). We like to cut these strips a little oversize and then sand them to fit nicely into the corners, as shown in fig 10c and 10d. CAUTION: Be sure to orient the kerfing with the flat side up. level with the top edge of the ribs.
Fig 10a
Fig 10c
CHECK-POINT: You should be installing the kerfing on
the soundboard edge of the frame. You should see “S.B.” written on the ribs at this edge of the frame all around.
We use spring-type clothes pins to clamp the kerfing in place (fig 10e), but you may find some other small clamps to pinch the parts together while you glue these kerfing strips in place. If necessary, you can increase the clamping pressure by wrap­ping rubber bands around the clamps as we have.
Work your way around the soundboard edge of the frame with the kerfing, but don’t do the back edge yet -- that will be easier to do later.

_____11. OPTIONAL: You can reduce the weight of your guitar a little by trimming off the large inside corners of the corner blocks, as shown in fig 11a. This step is optional, but it is recommended.
The illustration shows a chisel, but we use a power drum sander to do this job more quickly. You’ll want the corners to be trimmed so they blend in with the thickness of the kerfing, as shown in fig 11b.
NOTE: If you decide to leave the corner blocks full size, you should at least bevel the tops of the inside corners by sand-
ing them at an angle so they won’t touch the soundboard (fig 11c). This helps prevent cracks in the soundboard later, and allows for a little more vibration in the top.

_____12. This is a good time to open up the slot for the tenon in the heel block so it looks like fig 12a below. You could do this by hand with a sharp chisel and/or razor knife, but we use a router with a flush trim bit (fig 12b). The goal is to trim away all rib material that covers the pre-cut slot in the heel block.
Fig 12a Fig 12b
_____13. Make yourself a long sanding block now, us­ing a flat board about 2-3” wide and at least 16” long.
Apply double-stick carpet tape to the flat face of the sanding block, covering the face the full 16” length (fig 13a).
Cut coarse sandpaper (60 grit) to match the width of the board and press the clean side down against the tape (fig 13b). You can add to the length of the sandpaper by pressing a second piece in place at the end of the first.

Fig 13b
Then use your flat sander to level the entire front edge of the frame. Keep the sanding block flat by always having both ends resting across the instrument, as shown in fig 13d.
The pencil marks should all be cleaned off by this sanding work. Keep sanding until they are all removed.

PREPARING THE SOUNDBOARD
_____14. Now you can open the sealed bag and begin working on the soundboard. First thing is to outline the inside of the frame on the inside face of the soundboard so you know how to trim the braces.
We have marked the location of most of the braces in pencil, but there are a few things you need to draw. Begin with making a line 4” from the sound hole and perpendicular to the center line, as shown in fig 14a.
Center the frame of the guitar on the centerline of the soundboard, lining up the heel end with your pencil mark (fig 14b).
Then draw a pencil line around the inside of the frame to show where the kerfing touches the soundboard (fig 14c).

_____15. Find the two X braces and connect them together in the middle. Note that there is a wrong orientation for these braces (fig 15a). When properly oriented, the X will match the outline on the soundboard, as shown in fig 15b. Center the X on the soundboard and mark where the ends of the braces cross your outline of the frame.
WRONG RIGHT
POINT OF INTEREST
Some purists will leave these braces long enough to fit into “pockets” that they cut into the kerfing. This is difficult to do well, but helps prevent a brace from breaking free at one end due to future abuse. We pro­vide bracing long enough to al­low you to choose this method if you wish, but it will increase your working time a bit.

_____16. Before gluing the X braces in place, test your clamp­ing system without glue to make sure you have sufficient pressure everywhere. You want even pressure across the full length of the braces. Make sure that the ends will be pressed fully against the soundboard. You don’t want these braces to come loose!
When all is ready, glue and clamp them in place to the sound­board, pressing them against your flat clamping board. NOTE: be sure to put glue in the notch where the two braces intersect.
Use the spacer block (or other long scrap) across the soundboard to press the intersection firmly (fig 16).
Wipe off excess glue and leave the clamps in place for 3-4 hours until dry.
_____17. When the braces are dry, use a chisel to clip a 1/4” end of the thin flat back bracing material to use for a patch across the intersection of the X braces, as shown below (fig 17a).
Glue and clamp this patch across the intersection forming a “bridge” to tie the bracing together firmly (fig 17b).

_____18. Mark and trim all but the three shortest braces, and glue them in place where they are marked on the soundboard (fig 18).

NOTE: Hold off on the three short soundhole braces for now. It is easier to shape and sand the larger braces be­fore installing the short ones.

GLUING THE SOUNDBOARD
_____21. Be sure to keep the spac­er block firmly clamped to the frame for this operation! This will help hold the shape of the body as you apply clamps.
Test-fit the frame on top of the soundboard without glue first, to see how the braces fit inside the kerfing. Trim the braces as necessary.
NOTE: If you plan to cut pockets into the kerfing for the ends of the main X braces, this will take some time for trial and error fitting.
Plan out your clamping method and assemble enough clamps (or Bun­gee cording) to do the job before you begin.
spacer block
We show two ways to clamp the body down against the soundboard:
20 clamps, as shown in fig 21a, or 20 feet of light bungee cord­ing (available from Musicmakers), as shown in fig 21b.
If using the Bungee cord method, put screws around your flat work surface at an angle, about 2-3” apart, for wrapping the cord. If you didn’t make a 22” X 28” clamping board, you can put the screws in the edge of your smaller plywood instead of 4” away from the guitar as shown.
When ready, spread glue all around the edge of the guitar frame (including the kerfing), and put the frame back on the sound­board, making sure there are no obstructions preventing a nice flat fit.
If using Bungee cord, tie a loop at one end, hook it on a nail and work your away cross the instrument in spider web fashion to press the entire frame down firmly against the soundboard (fig 21b).

Fig 21b
PREPARING THE BACK
_____22. When the soundboard is dry, remove the clamps and turn the instrument over so you can start working on kerfing for the back edge. Begin by leveling the edges of the ribs and corner blocks, using your long flat sanding block (fig 22).
The goal is to eliminate glue blobs and other irregularities that will interfere with a good fit of the back panel. You’ll be sand­ing more after the kerfing is installed, but you’ll use a curved sanding block next time.
HINT: Leave the spacer block in to stablize the frame as you sand, until you get to the heel and tail blocks. You’ll need to remove the clamps in order to sand those areas.
