I am planning on buying a DC to save cleanup time. Thinking of something like this

Does any LJ here have these basic DC, and is the 570CFM sufficient?

I’ve read somewhere that either you get a DC just for collecting sawdust for less cleanup, or you go all out and get something that captures all the fine dust. I only have one 110V circuit garage and it’ll stay that way for now, so it looks like the former choice. I have a delta air cleaner and wear a good mask.

I don’t plan to run more than one machine at a time and probably roll it around and use a short hose. DC will be used for
1.5HP Contractor saw (I will seal the back soon, but shark guard is too expensive for me)
14” bandsaw
6” benchtop jointer (with sawdust impeller)
10” sliding mitre saw
Router table
maybe DW735 planer, some say its impeller overwhlem a small DC

The Delta 1.5HP one gets a little bit expensive at 3 times the price, and I figure I will go cheap now and upgrade to a really good one later if necessary.

But is 570CFM enough for just one machine or not even worth the effort?

thats pretty low to move the fine dust, it’ll help with the bigger stuff.

You don’t really need to seal the back of a contractor saw, the bottom pans, especially the one woodchuck designed (tapers in lower to create an acceleration) do wonders for catching the saw dust.

True, but then for that price I would expect to make some compromise. I’m hoping the dust filtrator will pick up the fine dust floating around, or at worst I can open the doors for a bit. See if I can hook up a cyclone lid before that and hopefully does not reduce airflow too much, and just use it as a chip not dust collector.

The bottom dust pan that came with my delta contractor saw is somewhat tapered downwards though not even close to 45 degrees. I missed Woodchuck’s thread on that and now he’s taken his content offline. Too bad, I find his comments does make the forum more fun

Most of the offbrands like that one tremendously overrate their cfm capacity. I would guess that in actual conditions it is 1/2 to 1/4 of the claimed 570 cfm. With that said, anything is better than nothing, but I wouldn’t waste my money on it.

I researched this topic before getting a DC and was told that if I got a unit smaller than 1 1/2 hp, I would want to upgrade within the year. I got a 1 1/2 hp Jet DC and replaced the cloth filter with an aftermarket pleated sub micron filter and never looked back.

I forget who, but some company makes woodchucks thing commercially now for ~20 bucks. Worth it IMO, the little taper on the ABS one doesn’t do great. The deeper design that he had actually shaped the air a bit so everything started moving in the right direction.

I would look for used in your area, I managed to score a ~1200 CFM jet for 150 and a little driving.

I would not waste my money on a 1 HP if you can see your way to get at least 1.5 or higher. They work fine if you keep the unit next to your machine, but the ability to draw dust decreases dramatically if you later try to extend the run to 10 feet or longer to service multiple machines.

I was in the same boat, and passed on a couple of offers of ~$70 for the Delta 650…. until I found a used Jet 1100 for $150 …. was worth the wait, as this thing is powerful to get chips and fine dust, and I dont need to upgrade it (I also have it plumbed with 2 runs for my machines ,and it works great!)

PS. as mentioned- check out Wynn Environmental website for their upgrade filters.

here is my blog about it

Thanks everybody, I will look up craigslist while saving up for a Delta 1.5HP DC. For the woodchuck/PSI adaptor I’ll see how much they charge for shipping to Canada, and I suspect shipping will be more than the item itself. It was the same situation when I want a Rockwell Fence Clamp and found out the shipping was double the price of the clamps. The adapter angle does look much more aggressive than the stock delta one

Sorry for the bad pic. I put this together for about $125. It helps keep the garage clean. It is not great, but it does work. The dc is the Harbor freight mini, 1hp, I think 600 or 650 cfm. A grizzly seperator on top a trash can.


In the basement , I use this.

I like the garage to be clean, so I use a shop vac after using the dc. Then I use a leaf blower to get the rest. Then I turn on the ceiling mounted air cleaner, and go around with the leaf blower and really stir up the air in the garage, so the air cleaner gets it.This is with the garage door closed.

The one in the basement is much, much better.It all depends on how much money you can throw at the problem. I hope this helps.

hairy, that looks like a nice setup for my small floorspace, and something I can keep later on if I upgrade to a delta 1.5HP or something better. I need tio check around for price of these portable units also, up here things tend to be more expensive. Nice looking bike you got there in your shop

Here’s a link.
and another If you wait, they will be on sale someday. Like I said, it works, but it’s not great. One thing I had to do to it was remove the intake screen on the sucker. It clogged first time I fired it up.
