Alternatively, there is a black banner near the top with white font options. One is "Articles", and this may have you honed in on your needed resource very quickly.

Welcome to the forums. I suggest you go to the top of the page and click on Resources, then search for hollow core door, also might search for folding layouts. Should get a number of ideas, maybe even the one you remember. Good luck,
Good thing someone put the edit function in!
I should have added that you go to the Index of Magazines under Resources to search.
Good luck,
Years ago, there was an article in MR showing how to build a layout incorporating 2 hollow core doors. It folded up and would fit in the back of a station wagon.
Does anyone remember this? I would like to get a copy of the magazine or the article.
