Tenor Guitar and 'Ukulele Necks

I built 2 tenor guitar necks with the same process as I use for tenor 'ukuleles that have a Spanish Heel joint to the body.

This is not a typical construction method that I have found online, so I am kinda hoping for the best. The tenor guitar necks will also have a one-way truss rod installed for future neck adjustments.

*** Note about neck joints....... on steel string instruments, the most common neck joint to the body would be either a dovetail, mortise and tenon or bolt-on attachment.

The Spanish heel joint is commonly found on classical guitars with nylon strings, hence, my "hoping for the best" result.

I chose this method because this is the only method I have used in the past....  The third tenor guitar I build will have a dovetail joint.

 First, I cut my stock into the following pieces;
1) Main neck
2) 2 Heel blocks that measure in hieght-3"
3) Tail block
4) 2 ears for the headstock

Using a neck scarf joint jig, I cut the main neck block at a 15° angle.

 Making sure the joint is tight I sanded the scarf joint flat.

Glued the scarf joint then the heels blocks together.

Here are the three rough shaped necks side by side.
