Does anybody know of battery operated floor sweeper suitable for wood shops? It would be preferable to have a small cyclone upstream from the filter. I often wonder how many man hours we spend sweeping the shop. We have dust collection, but it just doesn't get all of the sawdust.

How clean are you looking to get?

I've got decent dust collection on equipment. Sanding is done at either a downdraft table or with a vacuum.

Unless somebody makes a disaster, we generally don't touch a broom until Friday. Everybody spends an hour picking things up, organizing, and cleaning. There is four of us so we spend about 4 hours a week cleaning. Or 2.5% of the work week. That also includes taking all garbage, sawdust, and scrap/drops to the dumpster.

I've found that one you get a shop clean, it's pretty easy to maintain it. Habits need to be altered. Slobs need to have their slob ways beaten out of them. After a while, everyone gets used to it and it becomes self managing and they prefer working in a clean environment rather than some dirty dump.
We usually take one day in the spring and another in the fall where all we do is clean. Blow off all the dust collection pipes, clean windows, open up covers on equipment and blow out nooks and crannies. Things like that. Basically making it ready for auction.

The rest of the time we blow off work areas and just sweep up. In the heating months I'll chase the floor with sweeping compound to pick up the ultra fine stuff the broom can miss. Sometimes damp sawdust which helps bump the humidity up. 40" wide brooms cover area quickly too.

When it's nice out and the doors can be opened, 8k ft³ takes half an hour or less by one man after being swept to blow everything out with a leaf blower and works extremely well.

I regularly have salesman tell me I have the cleanest shop they call on.
I regularly have other cabinet shop owners make fun of me. I ask them how a dirty shop has a better return than a clean one. Haven't gotten an answer yet.
Cleaner is healthier, safer, and it breeds a mindset that is difficult to achieve otherwise.

I think it is time well spent.

Karl,
Your shop organization is impressive! I’m sure it pays dividends.

Using a leaf blower in a wood shop is a very dangerous undertaking. Ask the fire marshal about it. With a leaf blower you are creating the dust cloud and the blower is the ignition source.

There are many battery floor sweepers available. They save an incredible amount of time. Keep an eye on the used market. They are not perfect but very fast.

It's dangerous in your woodshop.

Not in mine.

I'd have to have enough dust to reach a duration level high enough for it to be combustible.

Ok sure, but you suggested it on an open forum. It is a dangerous thing to suggest.

I would like to see your shop operate. What do you make?

Dangerous? Virtue signal much?
I get it. You're a superior human to me. Congratulations Bill.
I make money in my shop by building cabinets.

You understand dust is explosive. Although your shop has no dust most others do. I am trying to warn the rest that your process is dangerous. Do you disagree?

5/4/24       #10: shop vac ...
Bill

Correction, that part of your process.

I fully understand you are pretending you are enlightened and superior by overstating the dangers of dust exploding.

Have you ever intentionally tried to get dust to explode? It's harder than you think. That AFR is tough to hit even with an open flame. If your shop is so filthy that you can hit that mix with a leaf blower, than you aren't looking to clean anyways. Plua, you're in trouble if you use compressed air or even open a door. So if you've cleaned your shop as I said and use a leaf blower to get the last bit ushered out the door, the risk of something grenading on you is pretty well non-existent. You take far greater risks at the grocery store.

Do you use vacuums? Do you understand the dangers of rapid decompression? That is an equivalent level of virtue signaling thought process.

Wow Karl, strong feelings on this. I communicated I believe it’s a dangerous practice. Not a personal attack on you. Lighten up.

Followed by the typical gaslight.

Strong feelings? No. Just tired of absurd claims made by people trying take some high ground that doesn't exist.

5/6/24       #14: shop vac ...
Bill

Ok, personal attacks are not needed. We disagree.
High ground, virtue signaling, superior human?
Kind of extreme don’t you think?

Have we had some prior interaction I don’t recall?

Didnt he ask about a battery shop vac?

I was not going to point out that Karl, from his high perch never answered the question. but since you brought it up. I believe what he did was in his words virtue signaling. Too funny.

I use a leaf blower all the to get the fine dust out, whats so hard about turning off the "ignition " source when you do? Also one problem with older manual machines they weren't designed with very good dust collection ports. My slider has a captive dust shroud around the blade and in the guard. My Rockwell 12/14 cabinet saw has a cabinet the size of a washing machine with one 1-4" port on the bottom back, and with a powerfeeder you have to mickey mouse something on top.

Bill

Yes it’s not a problem until conditions are just right. Very rare but catastrophic.

The blower itself is the ignition source.

Dust collectors have spark detection, extinguisher systems and abort gates for a reason.

I am out. The horse has been beat twice death.

Now THAT'S fleshing out an opinion!
I get what Bill is saying...it could happen in the vacuum of space 🤣 I guess.
Seriously I suppose it could happen once you hit
that threshold which seems pretty high
An enclosed dust collector system seems a different animal
Karl- I like your style
Very impressive shop keeping

I'm With Karl, I don't think I could even get the finish room to explode with a leaf blower...I wouldn't try it, but definitely I could not get a dust explosion in the shop using a leaf blower.

Boys, boys. Quiet down. Like his writing style or shop habits or not, Karl spent a lot of time responding to the OP. Karl probably has 5-6 words to Bill's one.

It is not easy to respond as Karl did. Bill only threw stones, with no solid information added to the mix.

I think it reasonable to think that no shop owner wants any kind of fire in his shop. That is baseline fact.

Karl has provided a photo of a professional shop, while Bill has not shown anything.

I retired 2 years ago after 52 years as a professional woodworker. One thing I can say for sure is that there are a lot of shop owners that act as if they do challenging work for their daily bread. Not that Bill is a pretender, but the only skin he has in the above dialog is verbal.

I agree that became unproductive.

Here are a few photos. I can’t find one of the collector at the correct angle to show the abort gate. It has full fire suppression though.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards.
