Nice job! Question, what purpose does having those horizonal braces half way up the wall studs serve? I assume it makes the studs more stable and also eats up a lot of your time as they have to be hand nailed in on each end? I did not see a nail gun? Also, those have any effect on fire code? My walls are bare studs too and I wondered about this, the insulation goes in Monday...PLMK
The main reason I put the blocking between the studs was to help prevent warping or twisting of the studs. I use the book "The complete guide to home carpentry" by Black and Decker for reference. This book calls these blocks "fireblocking" and says its required by local code. I hammer in 10d 3" nails on each end of the blocks after drilling a pilot hole for the nails. I don't need a nail gun as I am in no great rush to get done. I really like how stiff the studs feel after the blocking is in place.
