A 50 years old Yamaha - Wrapping Up
Continuing from my last blog entry, a layer of spruce was fitted to seal up the final gap on the guitar top.
To facilitate the next process, which is gluing the guitar neck to its body, the layer of spruce has to be flushed to the flatness of the guitar top. It was done by chiseling all protruded parts carefully.
Preparing the neck to be re-glued required a new angle to be set. This step is critical to the entire process. Setting a new angle required the neck joint to be recut on all three contact surfaces or sides. There was no jig to guide this cutting process except experiences. Steadily and gradually wood materials were chiseled away until a new angle is set.
With the guitar body and neck prepared, it was time to re-glue them back together. The gluing and clamping processes were not technically difficult as long as the preparation work has been done properly. The clamp was left on for at least 12 hours or overnight. The new neck joint was given another 24hrs to cure before applying stress on it.
The big day; setting the guitar for good playability. Usually a new saddle is needed because of the new neck angle. The new neck joint was stable and the guitar was set up in a breeze.
Resetting a new neck angle is technically demanding. This guitar has been given a new lease of life after many challenging processes. It was indeed a fulfilling restoration job.
Four videos documentation were done to record the mentioned work processes herein. Scroll down to view them.
Here are the brief summary of the videos.
1) Part 11 - Flush trimming the fingerboard tongue footprint
2) Part 12 - Resetting a new neck angle
3) Part 13 - Guitar neck to body re-gluing
4) Part 14 - Restoration set up
