dread backs

[dan parsons]

 I have a tech question about dread backs.  ive been a finish carpenter for over thirty year and played guitar since the 8th grade. a few years ago i couldnt afford the guitar i wanted so i decide to make it.  Ive made 20 over the last 5 or 6 years, usually 4 at a time, every summer, because my shop isnt climate controlled.  Mostly handcarved archtops. and a couple dreads.  i started 4 dreads last year and ran out of warm weather so i put the 4 backs that i had braced away till spring. when spring came i bent my sides for 2 and put the backs on. then i notice the backs were actually bowing the other way against the braces. im guessing from humidity and temp and different woods. but will they go back or should i cut the bracing all off and start over.    thank dan
