commercial lumber isn't straight in any direction. it can be close to straight sometimes, but you have to pick through your lumber to start. depending on how the boards are cut they will cut or warp, and if there's a big knot like you had in one of your bottom cords, there is not board there any more on one side. you can fix this by picking through your lumber to find the straightest boards and then from that set pick the ones that are closest to quarter-sawn, free of heart. Or you can run the boards through a thickness planer twice to make them square as they are then, and hope they don't warp too much as they age. i wouldn't have used the board with the knot to make the truss. when i'm using lumber for floor joists I'm always having to shave some of them a little here or there to account for variations in the boards.
Impressive that your kids help so much. That is awesome. Thanks again for the video content
They're young and have a lot of activities so they don't get involved that often but when they do they are a tremendous help.
There are a lot of people that, like you, I don't see using feather/finger boards on the table saw when ripping long boards. Just wondering why. 😮 ❤
I do when I'm cutting something that I'm uncomfortable with but usually don't use one.
Thought you might plane 🤔 the top of that truss to flatten it. Not comfortable using a saw that way.😮❤
It's all about your comfort level.
Do you have a laser level, or pull a string all the way across the top to see if there are any other variations.😊
I used a 4' level to check 3-4 trusses at a time and eyeballed down them to check as well.

Thanks for the advice. Always learning.
Is it possible that the board on the wall that you fasten the truss to is bowed? Could that cause the problem?😮
Towards the end of the video I found that the bottom cord was warped which caused the whole truss to push up.
IF YOU DON'T KNOW WHAT YOU'RE DOING DON'T DO IT
If that was the case, then no one would ever do anything.
