Review on Enhancing Woodworking Breadboard: Alignment Extension Furniture for Perfect Precision by Ryo Flora

These pegs are used to replace (or align) table tops. If the existing pins are broken, missing or damaged AND if they are centered correctly (not cheap Chinese junk) you can use the Dowl-It to center and drill out the bad pin and replace it with a new USA made blade to replace pen. This way you don't have to spend $1000++++ on a new dining/kitchen table. Inexpensive solution if you have the tools and knowledge how to do it. And when you put in the spare pens, none of that hot melt goo will be left behind.
