sears used to sell a tool vac, don't know if they still do. it did a good job keeping up with a 4 and 5" orbital sander. feeds thru the side of the grinder shroud , you have to use discs with holes in them.

porter cable sells orbital sanders with holes in the disc backing plate just for this.

You can't see what your doing if you put those things on. Just hold the grinder in one hand and vacume in the other. If its big grinder work suit up and get into it.

Check out Festool: Power Tools, Sanders, HEPA Dust Extractors, Tracksaws, Jigsaws, Drills, Routers for Professionals - Festool Power Tools

Can't believe what I spent on this stuff but it works great and there is little or no dust. They used to make a nice grinder with a curved brush like a dust guard that would catch the dust and it could be rotated around the disk with a turn of the handle...don't think they make those any more but they do have a bunch of different sander/vacuum combos...these are all designed from scratch to collect dust, not just an "add on".

When working outside, I set up my leaf blower (electric) to either pick it up (suction mode) and blow it out a piece of dryer vent hose. Or just blow it away working with the wind.
Don't know what the neighbors think but I don't do it that often either.

I have a couple gas models and an electric so I could make quite a storm!

Neighbors all know i am nuts so that is already taken care of.

What do you do your grinding with?

Thats what I am looking for. I need to get down through paint and into the guts of some fiberglass to get to work and dont want to wait for some slow ass grinder to get there.

How about a little finer work? DA or orbital or something in between to take the first big bite after everything is cured?
I like these for grinding after the other wheels.. or for scratching before laying up additional layer or tabbing. These also last forever and blow away sanders. Get them at harborfreight fot 10 bucks though. I just cant find them online right now but they have them in the store.

just bought a couple of them. Thanks very much.

How about sanding? Some disc options from 60 to 80 or so? Thoughts?

I like 80 on my DA sander and go up from there. I use 36 on my soft pad for doing a large job like sanding the deck for new gelcoat, then hit with the da. Poly fair I take down quickly with a board sander and block. If you sand at the right time, (before its kicks all the way it hits this rubbery stage), you can take down the big spots quickly. Then da after it kicks all the way.
