A few months ago I located a good adapter to attach this sander to a small shop vac, should have purchased it then. I took a picture which I now can not find. I think I was looking at the questions on amazon but it may have been NCW. It is a standard plumbing fixture. I looked and HD had it in stock. It is packaged individually and cost around $5. I know this is a shot in the dark but I thought I might get lucky and someone may know what I am looking for. Unfortunately I can not go to HD, heart issue, and just look until I find it.
