scottbr 20th November 2020, 11:21 AM I'm in the planning stages for my shed and working on my dust collection solution.
I will have questions down the track about the main unit - and yes, I have read and will read again all the relevant posts before asking any questions.
The main machines will be serviced by a DC with ceiling mounted 6 inch PVC and drop downs etc.
But the mitre saw will be some distance from this and it will be tricky to get a straightish run to it.
I'm wondering whether I'm better off connecting the mitre saw to the DC via a long run, or connecting it to a smaller dedicated unit sitting right behind or beneath it. Something like:

tonzeyd 20th November 2020, 11:38 AM I would lean towards the main DC would be better, but it depends on the following:
- How long will the long run be?
- Would the main DC be located outside?
- How many HP is the main DC?
The biggest issue with 1hp DC's is they leak and they don't have enough pull to have a significant impact.
scottbr 20th November 2020, 11:44 AM Thanks for responding.
- The run would be around 8 metres along the ceiling with a bend.
- The main DC will be inside - I'm in the burbs.
- HP of the main DC is yet to be determined. It will be mid range and cost.
havabeer69 20th November 2020, 11:47 AM Depending on what main unit you get i would be looking at using thr main DC.
Really your DC should be outside or closed off, having another DC will just mean you have to vent two DC's
riverbuilder 20th November 2020, 11:58 AM Just connect it to a shop vac, or similar, then you can use it for other tools too, like a router.
scottbr 20th November 2020, 12:16 PM Thanks. It's going to be problematic having the DC outside because of the location of the shed.
I would be able to enclose it within the shed and perhaps vent it through an existing 6 inch hole in the external wall, but I don't know whether a DC will vent that way - have not researched them enough.

I have a Festool vac that I use for my Festool tools. That would suffice?

I think the question should be not how many horsepower but how big is the impeller. A 5hp motor with a 12" impeller will not work any better than a 3hp motor with a 12" impeller.
scottbr 20th November 2020, 01:49 PM I suspect with the little 1hp DC that I referenced, there is not the option to change the impeller.
My question specifically was whether that small unit positioned close to the mitre saw would be more efficient at collecting dust than connecting it the main DC, the size of which is yet to be determined.
The consensus seems to be that connection to the main DC would be best, or just a shop vac.
Chris, I see you and in Helensburgh? Do you know of anybody in Sydney who would visit a shed in the inner west if Sydney and give some paid advice on the best dust collection solution? I should add, I don't need someone with qualifications or anything like that. Just someone who knows more than me.
elanjacobs 20th November 2020, 03:00 PM DO NOT BUY a 1hp extractor, they're more useful as a paperweight than at collecting dust.
Mitre saws are notoriously hard to get decent extraction because they tend to spray dust in all directions; a shop vac will probably do more than a 1hp DC, but the best solution is to build a shroud/hood around the back and hook that up to the main DC. Something like this

scottbr 20th November 2020, 03:11 PM Thanks.
Yes, I will build a shroud.
And the bench that saw will sit on can be pushed to the opening of the shed if need be.
From what I have read, the expensive Makita saw ($1,000+) has the best dust collection with a shop vac fitted.

Yes, I’ve got one that’s been hooked to my Kapex saw for 16 years or so, the other one floats from tool to tool.

I can most probably do that, do I need a visa? PM me your phone number and we can have a chat about the best way to do it.

Thanks Chris. You won't need a visa to get in, but there may be questions when you return. I'll be thinking seriously about things dust related in February next year - I get my hands on the building in late Jan. I'll get in touch.
