i have used that dust shroud sold by cd larue for over 5 years, it fits on a 7 inch grinder and works incredible well.. It does not lock down on the floor like other shrouds. they just came out with a 4 inch one, and i plan to buy that one as well..those plastic ones alot of people sell are pure unadulterated worthless junk..The metal band cuts through the plastic and the screws vibrate out. I have my shroud on a variable speed milwaukee grinder and it is one of my favorite tools to use. To properly use the black dry vac sold by dustless technologies, you need to also buy their clothe dust bag as well, otherwise the dust will collect on the canvas filter and you will lose all the vaccum lift. you should still wear a dust mask as well..We used to dry grind and polish concrete, i am well verse on the subject dust , believe me..That is why whenever possible i wet grind..

by the way, several companies recently came out with a powder you can add to the slurry, which turns it into a gel so the slurry can just be bagged up..you just add it to your slurry in your wet vac.

Might also try contacting Sherwin Williams. I know they sell the Dustless HEPA vac. They may have some accessories like the shrouds.

Baird,

Dust buddy is a shroud that attaches to some hand grinders and perhaps some polishers. You attach that to a true HEPA vacuum to keep the dust down to a minimum.

Google Dust Buddy but I think the website is Dustless something or other.

Thanks guys. This edge work is a pain in the butt. Stuart, what is a dust buddy?  You mean like a dirt devil kind of thing?

Five inch sandpaper should work well for you in this case. Good luck.

Linseed oil has a low very low flash point and unless you soak the applicator in water with some type cleaner you can run a HIGH RISK of catching a truck , your warehouse or wherever this applicator end up on FIRE !!!
