Dust extractor/collector for Table saw

[itsme_prasoon]

Hi,

I have an Ozito (2000W 254MM) table saw. Please advise on what kind of dust extractor/collector will be best suited. Is connecting a vacuum a good idea?

Thanks.

Cheers,

Prasoon

Hello @dbaarda 

Thank you very much for adding in those extra observations about the table saw. I'm sure our members appreciate the extra information, and it will come in handy when purchasing a table saw.

When reading your reply I noticed the "What table saw do you recommend?" question in the "You might also like" section at the bottom;

It mentions "Out of left field is Evolution 255mm 1500W Multi-Purpose Table Saw." Searching for that I found this;

That looks a hell of a lot like a re-badged version of the ozito table saw. The body, stand, mitre guage, and fence look identical. Note the interesting extra vacuum hose going from the blade guard! The blade guard does look different though, because on the ozito it's clear... but... look at the third picture they have of it, and viola! it's the same clear blade guard, again with the hose attached.

Its not exactly the same as the ozito package because they include a special multi-material blade and it must be narrower because I notice it has a narrower riving knife; they say 1.8mm, and on the ozito it's 2.2mm.

Morning @dbaarda 

Any chance of a photo showing what's happening underneath your Ozito table saw - especially with that vacuum hose?

Cheers!

[dbaarda]

Sure! These show the underside and how the dust-collection port and T are all part of the single injection-molded plastic part that makes up the blade shroud;

[dbaarda]

wow... those photos are not rendering nicely in the post for me, but if you open them up you can see what they are.

@dbaarda 

lol Yeah they dont look great but when I clicked on them they show nicely.

Thanks! @dbaarda 

All makes sense now. I was trying to figure out how it could suction near the blade. The entire blade appears to be encased in a plastic shroud with a vacuum port. What happens if there is no vacuum - does sawdust build up in the cover or does it just spit it out that port?

My extractor/collector is a wooden box sitting under the blade area.

Long story, but the original stand had no 'floor' as such and dust was going everywhere so I used a steel plate with a perfectly cut hole in it which once belonged to a hospital pathology centrifuge.

Works OK - mind you I only use it out in the open.

Hi @dbaarda 

"That looks a hell of a lot like a re-badged version of the ozito table saw."

I was thinking about this yesterday cleaning out my shed. It was very common in the late 1990s and early 2000s, in chain stores like Clints, Go-Lo, BigW and Kmart - but I would have thought this would not be the case now? But what would I know.

This is a classic example - both planers from the above period. Different badges, but the only difference is the coloured plastic.

[dbaarda]

There is a kind of "flap" on the side of the plastic shroud with a bit of a gap that is held almost closed by a screw with a big silver washer. You can see it in the second and third photo. I think that without a vacuum this flap hangs open enough for most dust to exit the shroud, but with a vacuum it gets sucked closed. I haven't actually observed it in action, but I do know that without the vacuum attached I end up with a lot of dust falling straight onto the floor.

An update on this. I looked into getting a similar multi-material blade for the Ozito and found there are a few other minor differences between these models that complicate things;

1. The motor is (probably different). The quoted power and speed is less for the Evolution (1500W, 3250rpm Evolution vs 2000W, 5000rpm Ozito).

2. The bore is different (25.4mm Evolution vs 30mm Ozito).

This makes it difficult to impossible to fit the same blade on the Ozito, both because the bore is the wrong size (there are claims specialist blade sharpening shops can re-bore a blade to a larger size but it's not recommended, and definitely not DIY), and because the blade specs say it has a max-rpm of 4500rpm.

In general there appears to be less blade options for a 30mm bore than for a 25.4mm bore, which is a pity. However, the Ozito has more grunt and a larger bore is probably necessary for that.
