How to Glue Guitar Sides to the Neck & End Blocks | Classical Guitar Build Step 9

(Building a Guitar, Step 9) Professional luthier Marshall Brune — with 30+ years building classical and flamenco guitars — shows you how to connect the guitar's sides to the neck block and end (tail) block using traditional hide glue, the step that turns bent sides into a guitar body. In this video: • Shaping the neck block and tail block (and why I run the tail-block grain horizontally to stop the shrinkage cracks I constantly repair on old Ramirez guitars) • Why I choose mahogany or Spanish cedar over spruce for dimensional stability • Chamfering the block edges with a chisel — and the safe way to hold the work • Trimming the block height to 94mm with a table-saw angle jig • Fitting the sides into the mold with flip-lever clamps • Marking to the line with a knife, not a pencil (a pencil line is 0.7mm of "insecurity") • Gluing the tail block with hide glue and clamping it all together Visit: https://www.mebrune.com/ To prevent cracks, use this! 2 Way Humidity Control https://amzn.to/4nx8Ion Support me on Patreon -   / marshallbrune   Use promo code: YOUTUBE to get $500 off your guitar purchase!
