My slots on this pylon lantern project aren’t great. I started searching for other peoples designs to learn from, and I found that several have this odd two sized slot designs. In the image below the slot has a larger upper section (Red arrows) and a smaller bottom section (Green arrows) .
Anyone have any idea why they created the slot like this? and what benefit it would provide ?
@funvill, I am going to hazard a guess that the top, wider portion is a clearance fit to allow easy insertion, while the narrower, bottom portion is a light press fit (pressing the tabs down into the slot) to lock the tabs so they are less likely to come apart.
After making the hundreds of bookshelves 2 years ago with slots like this
you want the finally assembled joints to be tight which makes initial
insertion difficult so therefore one makes the initial opening wider.
