Bench grinder collection bags?

[kunkernator]

We have these canvas bags at work, i want a set for a grinder at home. Tried Google, no luck. Anyone know a source?

Doesn't look like anything unique or purpose made? Just get a bag and put a band clamp on it?

It is hard to describe, but the neck (where it fits on the bench grinder) is the same size as the grinder outlet, while the bag is large. So it does look purpose made.

You could look at the collection bags you get with belt sanders or electric planers. They are smaller than that though.

What about these Bosch ones for their table saw

I got old socks on my stuff because I didn't find the nice canvas ones with a little google.

The socks work surprisingly well, (just look stupid and I hate it.) Just change out every so often.

I bet Baldor can sell you the bags. Probably have to call and ask.

Make yourself a collector with PVC that fires it down into a 5 gal bucket. cut a hole in the bucket for the pipe to stick through maybe even fill it with water if you want. I bet it will trap just as much as the bags do, you'd only have to worry about the real fine dust.

Those are exactly the style that I want the Bosch logo kinda pisses me off, but I may have to give them a try!

Good idea, but grinder shavings dont burn thru the socks?

If the bag thing doesnt pan out, i will probably do something like this.

I ordered one of these. If it fits, i will grab another.

Do you know someone that has a sewing machine?

So how did those Bosch collection bags work out on your grinder? I need something similar.

 

[Mickey O]

Use old vacuum cleaner bags, pick them up at garage sales cheap.

I do, and I'm going to be making one of those before I use my grinder next, but first I have to decide what to make it out of.

I'd prefer a fire resistant fabric. Either I'll look on eBay for cheap nomex socks, or I'll be soaking a ragged old tee in boric acid/borax...

 

[Oregon rock crusher]

Definitely need a flameproofed bag. This one was provided with an old Acme saw sharpener. Not that I have a source for a new one but I sure like the old logo on this one. Ed.

I've been looking into the idea of Nomex socks as a collection bag. According to the Dupont site, The Nomex material is heat and flame resistant. Nomex socks are typically worn by firefighters, race car drivers etc. Sounds like a good choice to catch hot grindings. Looking on ebay, a pair of Nomex socks can be had for under $20. Has anyone tried these on a grinder?

 

[torqueman2002]

I tried vacuum cleaner bags, but there is a fire hazard to consider.

I now use Kevlar Protective Arm Sleeves / Cut And Heat Resistant.
$22 from Amazon.

You could use a mortar/grout bag from Home Depot. Just need to close the one end somehow.

I rigged up a 5 gallon vacuum cleaner connected to my grinders via metallic dryer venting. I use a separate switch for the vac as I have it connected to two different grinders.

 

[tatra]

As mentioned, 5 gallon pail and some ducting . Half full , replace with a new pail . Used this system at work for years , most have been disconnected and **** everywhere. When in use did a good job .

I don't think those are fire resistant. I wouldn't want hot sparks catching them on fire.

I don't see why this wouldn't work, but I think that something bigger than a sock would work better. A grinder moves a good bit of air out the port, but a grinding wheel is a pretty inefficient turbine. Any back pressure will stop the airflow, and the collection bag/sock is effectively acting like a filter. A larger surface area will give less restriction that a smaller one. Along those lines, I've purchased several pairs of airforce surplus nomex thermals on eBay for well under $10 a piece in years past, and an arm or a leg cut from one of those would do much better than a sock.

Kevlar is even more fire resistant than nomex, but either is fine. Treated cotton would be ok, as would wool. Other synthetics would be bad.

I see two small problems with the arm sleeves, but neither is a deal breaker.
1) Kevlar is a ***** to sew and cut (nomex is a much more friendly textile).
2) Kevlar sleeves (at least the ones I own) use two layers, and the thinner the fabric, the more air will pass through it, so you'd probably want to cut the hem off of them and open them up (doubling the length).

Aside from not being fire resistant (which can be fixed by treatment), these are a tightly woven fabric (a heavy canvas) that will resist airflow. Sparks thrown in there will certainly be stopped, but you'll catch a lot more if your bag allows air to flow through it.

Looks similar in size to the canvas bags lead shot come in.

For normal (quick) grinding tasks I don't really worry about the particles but for sustained grinding tasks I do hook up my shop vac to the Grinders rear vent. I also do this when truing up or cleaning the wheels with a diamond tool.

 

[WWheeler]

Rather than reinvent the wheel, here's a post of mine from a recent similar thread ....

I've been looking at different ideas for this. For now I'm keeping it in the garage with wheels on two of the three feet of the grinder stand so it can be tilted and rolled outside to do my grinding - weather permitting - and then tucked out of the way when in use, but I am looking to do something a little cleaner to keep a pair of grinders in the shop.

Here are some other's bench grinder dust collection solutions I've found elsewhere (links below) that may give you some ideas. The first just vents to a coffee-can canister with stove hood exhaust filters, second a DIY downdraft out of a garbage can, and the third ducts to a can filled with sand...

[TreePointer]

I'm thinking collection bags for a handheld leaf blower-vac would be spark/fire resistant.

 

[ndnchf]

A lot of great ideas here. I just picked up my Baldor last night. I won't be using it in an industrial setting, just my home shop for occasional use. So I think a bag/sock will work. If not, I'll look at a more robust system.

 

[ndnchf]

I wanted to follow up on the collection bags I made. I decided to go with Nomex since its a fire retardant material. The easiest and cheapest route was to buy a pair of Nomex long johns off ebay for about $10 including shipping. I cut the legs off at the knees, and then sewed the bottom shut. It was then a simple job to attached them to the angle duct piece with hose clamps. They seem to breathe very well too. This photo is of the grinder running. You can see that the bags are only slightly inflated by the air flow. So they breathe well. I did a little grinding and checked for hot spots or singing - nothing.

So I'm pretty pleased with them. Under 10 bucks and I still have enough long johns remaining to make another set if I need it. Or use them as long john Bermuda shorts!

 

[nczo6]

That's a nice clean looking set up there, price is right too.

 

[ndnchf]

While I was at it I installed new grinding wheels, made new eye shield lenses, installed LED lights and fabricated a water pot. It's a pretty nice little grinder now.

 

[scooternut]

Nice job on the socks, hope this works out safely for you.

I have a new to me Baldor as well, quite the machine. I'm jealous of your light shields and tool rests though. My tool rests are factory Baldor, but they are not as HD as yours, and do not wrap around the wheel. I like yours better.

Those differences are what are some of what are different between and the standard and deluxe version of the grinder. They added a lot to the cost too.

Yep - that's why I made mine - under $10 and I have enough material to make a second set if needed.

I no this is a old thread, but I thought I'd show you guys what I'm gonna do for my bench grinder , I'm gonna get a few sets of these welding sleeves and sew the larger end closed and use a clamp on the other end to attach it to my grinder outtake port , should work pretty good

Those sleeves are pretty tight weave and after adding a fire resistant coating, they won't pass much air. I would try to find something more porous.

 

[PCustoms]

Old thread, but this is nuts to have a cloth bag (treated or not) on a grinder.

Metal flex pipe into a metal bucket with a couple inches of water.
