On my first pour I learned two things. 1. The next pour I was going to need more help. 2. A 2x4 was not going to cut it as screed board for a 17' wide pour. I got lucky and picked up two more volunteers. I also added 14" to each end of a 2x6x16 and a helper handle in the center. The first pic is of the guys who gave up their Friday to lend me a hand. You can also see the modified 2x6. The second shot you can see the screed board better.
