Just remember to measure each stud location individually before you cut them.. There is a 99.99% chance they all won't be the same length in an older home.
Already aware of a 1" difference 10 meters apart along a wall, which put me on gard. Though I didn't think of measure each stud location. Thanks for the heads up.
For connecting the tapcon'ed sole plate to the frame sole plate, can I use wood screws? I bought a box of 3 1/4" nails for my framing. I think they'll be slightly too long for the two sole plates.
