To do many of those projects I assumed I would need to buy a bunch of bar clamps. While I inherited a good starter stash of c-clamps from my grandfather, he didn't have any big-'ol-bar-clamps. And you can never have too many clamps.
Enter some bar clamps made out of scrap wood, from the Izzy Swan channel.
Looks good to me. I don't like spending money, and I'm really in this hobby to have things to work on and develop the fundamentals.
