Install the purflings The top and back are routed for body purflings, but you will need to complete the “points” of the channels, connect the channels at the neck end, and clean out any burrs left dur- ing manufacture. Use an X-acto knife and small micro-chisel to cut the points, clean up the corners, shape the channel and clean the bottom (top photo).
For the tight curves, create your own bending iron using a (Traditional violin makers use heated Hide Glue, but it’s dif- piece of copper plumbing pipe and a propane torch (above ficult to use because it cools and sets very quickly. For these photo).
Here’s a neat trick used by many builders. Clamp the bass bar Once you feel sure of your alignment, clamp the bass bar in in place above the curved top, then roll a flat washer along place without gluing it. With a pencil, lightly mark its location the top with a pencil point drawing the line of the curve onto on the top.
Clamp the top in place and drill a small hole (approx. 1/8"/3.175mm) through the top into the neck block (photo above). Drill a second hole through the top into the tail block. At the butt end, drill the hole within the area where the saddle will be notched into the top later (see "Install the tailgut saddle").
The fingerboard edges are already good straight lines, so ��������� ��� ����� ����� shape the neck to match these edges where the two meet. However, the fingerboard may need to be shaped to fit the neck if it is wider and its edges overhang. Smooth the neck/fingerboard so their edges are flush.

Cutting the mortise The heel of the neck will be glued into a mortise cut into the body. Cut this mortise following the marks you made by tracing the shape of the neck heel onto the body. Cut inside the lines; it’s easy to enlarge the mortise, but you don’t want it to be oversize.
Install the tailgut saddle The tailgut saddle supports the plastic tailpiece fastener and keeps it from damaging the softer wood of the violin’s top. Professional makers don’t cut and fit the saddle until the violin is finished and buffed, but we recommend that you do it now.
To hold the saddle for carving, use a scrap of wood with a Once the saddle is shaped and fits the notch well, set it aside. raised stop on one end that you can butt the saddle against. It will be glued in after finishing the violin. This will keep your fingers safely away from the cutting tools.
well sealed. Even with no color added, the varnish brings out a great color in the wood. After your sealer coat is dry, use a light touch to remove any lint or dust with 400-grit sandpaper (we prefer 3M Gold Fre- Cut®...
Level-sanding When the last coat of varnish applied is dry, carefully level it with 320- and/or 400-grit sandpaper. The high parts of the finish will be flattened by the sanding, and become dull. That leaves the low areas which are still shiny (shown in the photo).
Final-finish the neck Traditionally, the color of the violin covers the peghead and to find the color you want. We used ColorTone Amber and heel of the neck, but feathers away to an almost-bare playing Medium Brown, in tiny amounts, added to Behkol solvent surface on the back of the neck.
Slot the nut The nut blank comes roughly shaped to the correct size. Be The bottom of each string slot should be 1/64" (0.3mm) sure the bottom is flat, as well as the front wall that glues above the fingerboard (slightly less than the thickness of a to the fingerboard.
Fit the bridge The bridge’s taller side is for the bass strings, with the treble strings sitting slightly lower and closer to the fingerboard. The bridge will need final height adjustment and fitting. Flatten the bridge by sanding it on a flat surface. Do this sanding on the back of the bridge (the side with a logo stamped on it).
Before The bridge can be further reduced in weight by beveling the After sides and the edges of the cutaway holes, and thinning the feet if they are too thick. Raising the bottom arch between the feet reduces mass, and looks good, too. The string notches will be cut later, when the strings are on.
