Okay #woodworking people, I have a gripe. Why is it near impossible to find a simple vacuum hose adapter for a shop vac? I bought a low profile dust extractor and the ports are 2 1/2 in. My vacuum hose 1 7/8. I look on Amazon and I see them all over, but try to find them locally? I think I'd have an easier time finding the Holy Grail. Any ideas?
