Sawdust

I was considering a dust filter (like the basic Axminster one). I already have a Trend vacuum for extraction, although I can't hook it up to my tablesaw so wear a mask on those occasions. Anyone using a filter - do they do the trick, do they trap enough dust to make it worthwhile (rather than leaving it to all settle around the workshop)?

I'm a very unallergic person, yet even when wearing a dust mask, satinwood and rosewood dust will give me a fairly instant dirty throat which develops into a hideous head cold.

That DIY filter looks brilliant!

It's certainly not as readily-available as iroko or even olive but, if ever you come across any greenheart, I reckon you should look the other way! :? Seriously, if you don't take ALL the necessary precautions then the dust can give you a heart attack! :shock:

I'd second that - purple heart isnt much better , lovely wood but you really really need good dust protection. Also be very careful with yew when i was younger and more foolish (and poorer) than i am now i once gave myself taxine poisoning from breathing in too much yew dust - that required a trip to the hospital.

mind you that said breathing in any kind of wood dust, or indeed any kind of dust at all isnt great for your lungs and if you do it for long enough can make you seriously ill - I'd strongly recomend getting an air mask - you cant relly on a dust extractor alone as the majority of these only pick up down to 0.5 microns and its the really fine dust that does you the most damage.

Also on the subject of alergies some people are allergic to the fibres in bankasia nuts - for those i'd reccomend full face protection, long sleves , and latex surgical gloves (nb: i'm well aware of the dangers of wearing gloves near spinny things - thats why i said latex as it will tear if it gets caught rather than dragging your fingers in.)

Always wondered about that, I am sure I was told, at college, that MDF was not so available in USA as it is here. Maybe trying to underline the fact that it is dangerous in spite of its popularity.

Thanks Grindingone. Today I am going to set up the DE system in the workshop, as it is cold now I will be using the tools indoors more (used to drag 'em outside!!) so guess I have no choice.

PS - Bet we got more MDF than you!! :wink: :wink:

You guys may use more then we do but every store is piled high in that stuff and our stores are all over the towns,ask some of the guys who come over to visit....In the last 20 years I may have bought 2 sheets.Only because customer wanted it....

 

[Grinding One]

I should also say that a number of house builders here use the stuff because its cheap to make kitchen cabinets out of....The repeat business to install more cabinets later when the customer realizes that cheap was not the way to go.Stupid people do not look far enough down the road to see the benifit of buying the best first time..

If you don't want a dedicated dust extraction system due to space or complications, then I would like to recommend the Trend Air Shield, that'll help with filtering out all the crap:

It's also recommened for machining MDF so it's pretty darned good.

How did you get those photos there, Tom? And I've just noticed that mine isn't a Henry, its a David.....

Anyway, you can see that the principal is just the same as those cyclones you can buy, but this was just something I came up with 20 years ago to increase the capacity of the vacuum cleaner. The best thing about it was a bonus.......that no dust gets through the cleaner's filter and out into the air.

Blimey, I have one day in bed and you lot have really gone to town, haven't you? Next time I'll take the laptop!!!
Mike, as usual you have come up trumps, haven't you? I am sorely tempted to let the Rexon go. Thanks mate.

Wizer, I am still here, just, but I wouldn't fancy being in one of my lungs right now!

I have been in touch with a fella today who has just sold an elumatec, which I missed, but think he has another similar, folks - is it any good (should start new thread?).

The Mrs and bebe are still fine, no probs, so I think maybe it was the wood. And the **** don't help, eh?

Does anyone else have any suggestions for the Henry (David?) DE, I wondered about fitting it to the ceiling as I have a pitched roof in the workshop. Maybe if it only has to be emptied once or twice a year it'll be ok, Mike?
My henry managed to suck up a sock a few days ago (used as a rag for applying stain) which it had away without my noticing, only to be retrieved a few hours later amongst the shavings etc... They are VERY good, aren't they? I dunno if I would need anything bigger, I don't honestly think I will be sucking up many things sock-size from any tools, so....

Again, thanks a lot, all suggestions and advice duly noted.

Is that the Royal Wee, John? I can be pedantic as you like, but that isn't pedantry, it is just English. Really is a different word from real. If you mean real, say real. If you mean really, it's only another two letters, and it saves one from sounding like one of those damn colonial types - or worse, someone who *wants* to emulate GWB.

In summary - it real, real annoys me.

Neil, be aware that most of the problems with wood allergies and exposure arise from the very fine dust and the chemicals (toxins) released from the woods, so it is not necessarily the dust/chippings you can see that is the problem.

Standard vacuum cleaners will not filter out the dangerous particles, and certainly provide no protection from the toxic chemicals, in fact the majority of units sold for DIY shop use only serve to spread the fine particles and chemicals around.

Sounds to me you were hit by the Olive Wood, but Oak can be obnoxious too especially if very dry and producing fine dust.

Surely someone has spotted that there is no need for a comma between "which" and "we"..............

Of course you can. I can imagine 'god', some old dude with a beard etc.. but I don't believe there is one.

 

[neilyweely]

OK, fine dust. How much will the henry pick up if I rig it up to something like Mikes? I do not think the Rexon (150quid in screwfix) will do much of a job either, so what should I do? CAn I do anything with the Rexon to improve it? If not does anyone want to buy it!!!?? :lol: :lol: :roll:

Thanks everone again.

Something like Mike's 'trap bin' will certainly save having to empty the main extractor bag/bin so often, in fact I use basically the same on my lathe system, it will not however do anything to capture the fine dust; note the amount of it adhering to the statically charged cleaner plastic etc.

I don't think anything less than a fine cartridge filter is going to get you down to workable levels if you are becoming sensitized, even then a full air fed mask to En12941:1999 TH 2 P would be in order.

Best option is to arrange for your dust collection system to be outside the workshop so that as much as possible is dumped outside. Ambient air filtration in the shop and a mask then stand a chance of nailing what is left.

One tip, have a shower immediately you finish anything producing fine dust or covering you liberally with shavings, it can save you hours of reaction discomfort.

far be it from me to disagree chas , but my inclination would be to leave the shop, and remove my clothing before having a shower rather than doing it "immediately" but each to his own
