I am in the middle of finishing my basement–I have all the walls framed. I am going to start building the 45 degree bar and tie it into a wall on one side. Can I start building and tie it directly into the wall studs or should I drywall first? It would be a lot easier to drywall later so i can run pluming and electrical. Additionally. I am going to build the bar back and would like to tie it directly into the wall studs as well. What do you think?
