That’s true, Splint. Too bad I can’t get the lumberyard to let me pay for only the parts of wood that remain at the end. Yep, the mass drilling is done. And yes, the magnets are there to keep the spool blocks upright. The spool blocks aren’t likely to tilt out when the cart is rolling, because the two racks on each side are face to face when the racks are closed. But they could tilt out when she unfolds the racks or just bumps them when they’re open. 

Barb, I’m guilty as charged. The projects I do for my wife usually are a lot of work, but it’s a tiny fraction of all the work she does all the time. 

This project really makes me respect Kumiko woodworkers, who cut hundreds of tiny parts that fit together perfectly. Same for the wood model builders.
