So rabident asked me to come down for a day to supervise the drywalling process. Coordinating with the builder and his subs was not easy, to get them to commit to an exact date was a challenge so I was kind of on standby for the assignment. I got there Monday night and we found two walls without channel so Rabident and I finished what we could with the channel on hand but we were still 3 rows short on one wall. An emergency delivery of another bundle in the morning solved that and by 9:45 am the room was ready to rock. It took awhile to get the guys to down from working on the other floors And we started about 10:15
This is how we started 3 guys, no lift just a couple of ladders. One superman on stilts. One guy on the ground would hand the end up to the guy on stilts another guy would climb a ladder. Holding the drywall up with one hand and with a screw gun in the other the superman fasten his end then walked over and fastened the other. To start the first row they were having problems positioning the first sheet so it wasn't touching the framing and they wanted to do the walls first. So I suggested sliding pieces of drywall as blocking under the channel, installing the drywall then removing the blocking. That worked and everyone was happy.
I started out putting on the Green Glue but it must have looked like fun because by the end of the day all 6 members of the crew (including superman) wanted to take a turn so they could add that to their resume, I was happy to oblige as my hand was getting stiff.
Throughout the day a big concern was were they using the right screws, 1 1/4 for the first layer and 2 inches for the second. First and second layers were going up at the same time in different areas of the room and we kept looking over there shoulders and reminding them and as a final test we pushed the walls to see if they would move without being bound to a stud. It was in this process that I discovered that I could set up a standing wave in the 12 x 30 wall at about 80-100 cycles per minute. When I pushed in the far end would come out and if I did it repeatedly at the right frequency it would oscillate. It did however stop immediately if I stopped pushing.
I think the main room was done by 5pm, basically 6 hours for a 3 man crew before lunch and 6 guys after. The most interesting thing I saw was a kid who couldn't have been more than 150 lbs carrying a full sheet (4x12) in by himself.Edited by BIGmouthinDC - 9/28/12 at 5:33am
