I like to install a Honduran rosewood heel plate delineated by a piece of maple veneer on my Pinecones.
First I saw I nice straight cut from the head of the back for the plate to rest against. I use an exacto saw blade. They have very very fine teeth and cut very nicely. I really like exacto tools, reasonable, sharp as can be, and easily replaced when dull.
Now to clean up the area with this super sharp old English chisel, one of my favorite tools.
Here are the parts and pieces, the maple veneer is glued to the neck, the rosewood end cap is glued on top of that. When the glue is dried the whittling and final shaping begins.
Here it is all clamped and drying. We will see what we have in the morning
The fretboards are all glued on now. I took no pictures of the process but it is simple, The key is this little brass brad that is driven through the hole drilled in the two empty fret slots. You just position your fretboard carefully and tap the brads down to mark the position on the neck below. Then take the fret board off, apply the glue and re-locate the brad holes on the neck. Tap the brads in a bit and apply the clamps. The brads hold the fretboard in just the position that you wanted them. Really very simple.
