SUGGESTION:  As you are applying the first coat of finish, watch carefully for glue residue 
that prevents the finish from penetrating the wood.  Take the time to sand or scrape the 
glue off, before proceeding further with the finish.  Scraping a sharp chisel across the 
area usually does the trick without adding deep scratches in the surface.  Yes, this can get 
messy, but you’ll be glad you took the time to do it.  Nothing looks more amateurish than a 
woodworking project with glue spots still showing.

OIL or WAX

 -- Oil finishes will give your wood a low luster appearance, bringing out the nat-

ural color of the grain, but it tends to soak into the wood and appear dry and “thirsty” after 
awhile.  Some people are fond of a beeswax finish for a natural look, but it can show water 
spots if it gets wet, so you may end up needing to re-wax or touch up the surface in the future.  

POLYURETHANE VARNISH

 -- Any regular varnish will work fine on this project, but we 

think a wipe-on polyurethane is the easiest to apply because it does not drip or sag -- just wipe 
on a thin coat and wipe off the excess.   The advantages of this finish are its simple application, 
minimal odor, good durability, and deep, soft luster.  

LACQUER

 -- Many professional instrument makers use lacquer for their finish. The most 

readily available lacquer is called Deft Clear Wood Finish.  It is best to purchase a can of liquid 
to brush on as a sealer coat first, and then use an aerosol can of the same product to spray on 
the final coats. The advantage of this finish is its quick drying time, but the disadvantage is the 
strong odor of the toxic lacquer fumes. 

FINAL ASSEMBLY AND STRINGING

When the finish is dry, you can begin assembling 
the parts with the hardware provided.  First thing 
is to make sure the t-nuts are installed in the tang 
of the neck and inside the body.

We should have already installed a t-nut in the 
tang of the neck (fig 14, pg 5).  If it is not there 
yet, then press it in carefully (don’t pound with a 
hammer) so as not to crack the wood.

Then you’ll need to unscrew the back ring from 
the body to check for seven t-nuts inside there.  
Install them carefully by pressing them in against 
a flat table so as not to crack the wood. (fig 15) A 
drill press (turned off) works great as a pressing 
tool. 

FIG. 15

SUGGESTION:  Sometimes the threads get a little misshapen on the t-nuts, making it hard 
to start the cap-screws into them.  It is helpful to take a moment now to drive a cap-screw 
through each t-nut from the inside of the back ring, just to clear out any burrs or straighten 
the threads.  Then you’ll have an easier time with the cap screws later.  Don’t leave the 
screw in the t-nut though.  Just thread it in and back out again to clear the threads.
