I'm a shop vac virgin who just bought a planer and it has a 2 1/4 inch vacuum port. The Ridgid shop vac I just bought has a much smaller hose. Three questions: Can I get an adapter? Is that OK for the Shop Vac? And is my 4 gallon shop vac too small for the board planer, which throws out a LOT of wood shavings? Thank you!
