@@CReevesMakes here I am with a 90$ cordless ryobi sander that's backordered and a normal 10 gallon shop vac, although I could use the adapter that came with my Numatic henry since it's basically the same thing just like 2.5 gallons and dry only meant to be used as a normal vacuum lol.
Hey it’s all good! I started with a couple of RIDGID cordless orbitals and a 4 gal vac. I just started doing bigger projects that demanded lots of sanding. Good luck!
