Thread: How noisy are dust extractors?

Hi Charleville, the latest Australian Wood Review has excellent articles on noise of workshop tools, showing loudness for each, plus an article on shop vacs

Thanks Jill.

I was going to buy a machine on Tuesday but then the weather encouraged me to go and engage in my other hobby on the day with results as follows ....

The air quality experienced whilst engaged in that hobby was magnificent! (As were the noise levels.)


The ongoing discussion in this thread has been very interesting, though.

killing fish, destroying trees, whatever turns you on ..... he he he

As it says below my avatar, "primeval and nocturnal."

I was out on the water at 2.15 am to catch those. Very quiet then. My four-stroke outboard motor is also very quiet.

Now, of only I could get a dust collector with real grunt that was also quiet....



.

I have seen a highly effective dust collector for a Makita SCMS in a sawmill where it was used indoors to dock special species timber for orders. In effect it was a sheet metal box oblong on the front and tapered to a 125 pipe at the back connected to a 1200 cfm/min dust extractor. The whole SCMS was enclosed back from the docking table. Level of dust escape appeared to be negligible.

I have the same saw as you mounted in a precision docking bench but regrettably I haven't got the space behind it to go with the above approach. I have a Festool vac. connected as required to the machine outlet but I doubt the level of capture of dust as a % of that generated would exceed 5 to 10%. I rely on wearing a quality dust mask with primary and cartridge filters to make up the difference.

I try to keep the machining of MDF on the SCMS to an absolute minimum. It's a nightmare to me in a non-industrial situation.

Cheers Old Pete

Thanks Old Pete.

A very useful contribution.

Many thanks.

Nice catch, do I see trevally with some odd looking bream. Did you use plastics to catch them?

The catch comprises grass sweetlip (delicious!), bream and the trevally.

I have never kept trevally before and did not know that one should bleed them on capture so they are in the freezer and will be used as crab-pot bait.

Just as there are machine dovetailers and those who still prefer to practice the black art of hand cut dovetails, in the recreational fishing community the divide is bait fishos versus lure fishos, in particular soft plastics. I fall into the former category of fishos who still like to practice the black art of using bait. In this case, the fish were caught on pilchards and prawns.

Charleville, one thing about the Carbatec 2Hp dusty is that the vanes in the hoop support and accumulate dust. When one starts the dusty, this dust is stirred up into the filter and probably reduces its efficiency. I have opted to have the the hoop modified by Gregory's Machinery to reduce the amount of dust being blown into the filter cannister. Gregorys will modify the hoop and supply a pleated filter as a kit. I have yet to fully test the dusty after the modification, however there are forumites out there that are quite happy with this modification. If you are going to do this modification, then keep in mind you will be buying the pleated filter from Gregorys

Thanks Zelk.

I am starting to think that I should not rush into buying my dusty because every now and then someone adds more useful info into the thread.

You have given me an excuse to have a look at Gregorys though. They are a fair way from my place but I am familiar with them because I bought a 17" Jet drill press from them a year or so ago.

They are a bit of a nuisance because they do not publish prices on their website so I tend to look elsewhere.

Many thanks for the advice and the associated photos.

There's quite a few shop's who only quote POA because of the fluctuating dollar.

Ah. I never thought of that. I thought that it was just a come-on.


Thanks.
