I tried using Velcro straps to attach the table extension but it wasn’t a great option. I ended up using JB and 3 rare earth magnets attached to the underside of the table to secure the extension in transit. First, I located the spots I wanted to attach the magnets to the table. Second, I used 300 grit sandpaper to add texture to both the table bottom and the magnets. Third, I wiped away the debris. Finally a placed the magnets and let the JB weld cure overnight. The magnets are powerful enough that the extension holds in place under the table if I don’t decide to use it. NOTE: rare earth magnets are very strong so use extreme care and caution when working with them. I know these pictures are not great. Let me know if you would like additional photos.
