bracing with a radius dish
staring with a 25 foot radius someone made for me on a CNC machine .
I lay the same pattern out on a piece of 3/4 and 1/4 MDF.
using calculations and an article downloaded from the internet ,I figure out spacers.
next I drill holes and split the spacers
and glue them in place on the grid layout
once screwed down it creates the 25 foot radius
the dish now has the same curve as the back of the brace
now a full scale layout
then cut outs are made to make a layout template
this transfers to the soundboard
a homemade go-bar clamp I made a few weeks ago
3/8th dowels are spring loaded to glue braces in place
I glue in a few sections at a time
the arch is subtle
the arch will add strength and tonal value
next I’ll set up a spindle clamp work board and glue the top on
