Green Dome Top Build

[vc_row][vc_column width=”2/3″][vc_single_image image=”3034″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]I really enjoyed building this guitar: the client’s wood choices were spectacular, the green finish was intriguing to me, and Dome Tops are just fun!

The radius on a D style guitar back is about 15 feet and tops are 25 to as flat as 52 feet. I call these guitars Dome Tops for a reason. The back AND top hold a 7 foot radius. These guitars are visibly dome shaped.

Here you can see just how curved the back(and sound board) will be.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3067″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]This is the back in the ‘Go Bar’ deck. If you look under the back you’ll see a circular piece of MDF. That is called a radius dish and it is carved out to the desired radius. In this case convex 7 feet. If you can picture a ball with a14  foot diameter it would fit in that dish perfectly. In this case we place the back in it and apply our 7 foot radius braces. The fiberglass rods apply pressure to bend and hold the back to shape while the glue dries.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3068″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]Here I’ve mapped out the brace pattern on the inside of the soundboard.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3069″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]Setting up the elliptical soundhole.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3070″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]The channel for the double bound Koa rosette.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3071″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]Nice pic of the rosette installed and level sanded.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3072″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]Here’s a great pic of just how much arc there is in a Dome Top.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3073″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]Check out the scalloped ladder brace![/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3074″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]The completed top after bracing! The ladder brace is set at scale length. That mean the floating bridge will mount above it and transfer string energy efficiently to the soundboard.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3076″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]The bent sides are clamped and glued up in a jig to make the rim.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”2/3″][vc_single_image image=”3075″ img_size=”full”][/vc_column][vc_column width=”1/3″][vc_column_text]Here is the completed rim with kerfing radiused to 7 feet.

To me closing up the body is one of those.
