For dust-collection match-ups, this tennis ball tip is an ace

Struggling to come up with a way to connect a shop vacuum to the odd-size port on a sander, I spotted a tennis ball installed as a rail-guide bumper on my bandsaw. Eureka!

Using hole saws the same diameter as the hose and tool ports, respectively, I drilled through a tennis ball to make a custom-fit adaptor. It works great!
