Thread: Dust Collection Calling Wayne !!!

Ken,

Nice unit! As for collecting the dust from the mitre saw - good luck

I built a Dust Hood around my sliding drop and hooked up the dust collector (DC). It does get some (read not much) however, that is with the 1hp bag DC and 4" pipe so I am hoping the cyclone with 6" will make some difference. If it doesn't, I am going to redo the Hood and redo the saw mount so that it is sitting on two supports only. Then I will place a ramp under it angled back down to a second collection inlet. I saw this somewhere (web, tv, ??) and, at worst, it will collect most of the big stuff. Mitre saws are a pain to collect dust from. I will post a pic if/when I redo mine but that will be too late for you I guess.

Ken,

Not to steal Wayne's thunder, but there is now a nifty catch hood that sits behind your miter saw to get most of the dust, or you can make your own.



Frankly, the commercial hoods are pricey, but I've seen a couple of guys who made their own out of wood or by using a heat gun on an inexpensive plastic tub.

To make the collection even better, they put their saws on a box with a second 4" dust line. The box top is a piece of pegboard with the holes drilled out to about 10 mm.

Hope this helps.

Bill,

Thanks for the post. I did know about those hoods but they are not available in Oz and the price is way, way to much at $299 USD (about $500 AUD + Freight which would be heaps!!!). That is more than most hobby woodies will pay for the saw.

I have seen Terry's hoods and ducting (fantastic) and that hood is similar to mine. I hope that the 6" upgrade will make the collection better. I think part of my problem is that my saw is a Slider so when I cut wide boards, the hood is too far away at the start, hence the missed chips/dust I get. Anyway, I will see what happens when the cyclone get going and I get 6" pipe to the saw.

Ken,

What type of DC are you using?

Wayne,

My reference to DC is very much future tense. I have made the conscious decision to build a cyclone after reading all about yours, so I am trying to keep that in mind for each piece of machinery, but I have yet to start on it. That will be next.

Bill,

Thank you for your photos. The plastic one is about as ugly as it gets, and the other is what I was thinking of doing, so you have helped me make up my mind.

Ken,

Not only is that plastic one ugly - it is $299 USD!!!! (see www.downdrafter.com) For that kind of money I would want one with its own motor/filter/etc.

Good to see you are gunna build a 'Tornado' Let me know if you want any hints/tips. First tip, when you get started cutting the metal - WEAR GLOVES - that sheet stuff is sharp.

US$299 !!!!!!!! What a sense of humour. It would want to do the cooking and wash my car for that !

Wayne,

I would appreciate assistance, in particular the size/shape of the sheetmetal cutouts. (I intend to use a 2HP motor and 100mm ducting. My shop is 4 metres by 6 metres )

Ken,

Have you got Bill's spreadsheet plan from
http://cnets.net/~eclectic/woodworki...heetMetric.xls

This makes a cutout layout of the components but note that it is NOT to scale (problem with Excel).

As for the pipe, go for 150mm if you have not already got 100mm. At least use a 150mm main duct and use 100mm drops from that to the tools. Bill (and others) recommend 150mm (6") all the way to the big machines (including Mitre Saws). I know that 150mm sounds like too big a pipe but check out the links on bills site to others, particularly Terry Hatfield's at
http://cnets.net/%7Eeclectic/woodwor...eldDCDucts.htm

The one problem with this is the cost. I am using PVC sewer pipe and fittings with a little bit of 100mm Flex pipe to connect to the machines. DONT buy the PVC at bunnies/M10/True Value (True Ripoff) go to a plumbing supply like Tradelink. Price (approx from memory) examples:

6m 150mm PVC
Hardware Store $60
Tradelink $32

Y Junction 150mm
H/S $35-45
Tradelink $25

etc.

As for flex pipe, carbatec/timbecon/etc. are the cheapest I have found which is not saying the pipe is cheap. $33 for 1m 150mm! $17 for 1m 100mm. The Cyclone is the cheap bit, its the ducting that can kill the budget if you are not careful.

Cheers,

All,

I just re-found this link

This has two links (small and large file) to a video of a see-through cyclone in action. Says it all.
