I made this dished holding fixture to match the back radius and used vacuum to hold the back in place while I glued the top/side assembly to the back.
Final tap tuning and shaping of the bracing on a top.
Gluing the neck block and linings. I use a potter’s wheel with a dished work board to sand the sides to the same radius as the back braces. The wheel can be run very slowly with plenty of torque and safely does a very nice job sanding a radius into the sides and blocks.
