To be the strut joining the roof and floor of the truss

Got a couple students over to give me a hand today. They didn't like the idea of blocking up the carrying timber unless if more people came, so Kat and Dave came over, but by the time they got their my grandfather had showed up and pretty much said- put the fing thing up. God he's great.
Yesterday went to Durgin and Crowell for subfloor- not what I really wanted but the price was right. Then grandpa and I worked on the mill. He had cut out most of the joists- we loaded them, then cut 2x4's and 6's- reloaded onto my truck that night, unfortunately everyone left by the time I needed to unload the truck onto the house, but hey- all the joists are there, the timber is in place- one bathroom wall framed in, and straightened one wall. So straighten the other, joists go up. But I am going to bed.
