Why is it so difficult to find a Cyclone Separator for 4" hoses ?

I can easily find just the Cyclone top for a reasonable price if the size is 2.5” but if I want a 4” then it is either hard or impossible to find (Amazon.ca) or when found it is an all in one (amazon.com) that includes the bottom for a hefty price
There is a 4” kit but the design does not seem to create cyclone effect which is important I believe.
The dust is blown straight into the bottom of the barrel and if there is dust there already I guess it will air born that one which will be taken further by the exhaust

Can’t stomach the price …I paid 400 for the saw, I am not going to pay 300 for molded plastic…

Griz has a lid that fits on a trash can with 4” ports for under $40 …

You could always DIY it…

If you want something that performs a bit better than the molded lids and is a lot cheaper than a cyclone, make a Thien Baffle. http://www.jpthien.com/cy.htm

Take a look at making a thein baffle if you don’t want to buy a cyclone. It does a good job too. Plenty of posts on how to make it.

The trashcan lid you linked does create a cyclone effect although not as good as the funnel type of cyclone separator. I used one for quite a few years and was fairly pleased with it until I stepped up to the super dust deputy.

This seems a good suggestion.
In general if it is relatively cheap to buy I buy I don’t make things.
The reasoning he is explaining there made sense to me so I will attempt something like that
In this light I will go ahead and buy a kit
I am still unclear why it is so prohibitive for 4” !!! The 2” ones have a decent price

Ditto for me. It’s not perfect, but for $40 plus the price of a 32 gallon trashcan, it’s perfect enough.

+1,i use it for when im using the planer, it separates out about 95% of the chips and dust which is all i need to keep from filling up my jet cyclone.

Sometimes the solution to a problem is not cheap. $223 @ Amazon.

Minime, it was up there with other “the best money I spent” purchases.

You can buy one off Amazon, with free shipping, for $179.00 (see site below).

As to molded plastic, I own a metal Dust Deputy a molded Super Dust Deputy, A plastic Dust Deputy [dedicated to the sandblaster] and had but sold (on retiring) my metal three horse Dust Gorilla. In short, I have experience with both metal and plastic versions. From that, I say the plastic units are nothing to scoff at.

I made the bin under my SDD portable, because I take it out into the yard to vacuum cones and leaves using a HF collector I bought just for that purpose (it’s normally feeding a 3hp “4 bag” collector (actually, it has cartridges on top)). If it were the metal version, it would be heavy as sin. It suffers pine cone abuse just fine.

Hmm,
FIRST: A cyclone is not needed to work wood.

SECOND: If you are too cheap/poor to buy a cyclone, then don’t covet one.

As my parents used to say: ‘People in hell want ice water too. Get over it. ’

The only purpose for cyclone is to reduce the amount of dust that enters the filter, and therefore the time between filter cleanings. If you work wood everyday, and need clean filters weekly; then a cyclone makes sense to save precious time. But most weekend wood workers don’t NEED one, as they clean filters once every couple of months.

Another option to a real cyclone dust separator is the vortex separator that Jet patented on their dust collectors. The DIY version requires a large wok or frying plan. There are several posts on LJ describing them.
Here is how I did mine:

Best Luck solving your existential decision crisis of money .vs. time on cyclone for dust collection.

Had a Thien that I built a few years back. This summer the groove in the lid on my Thien cracked, and rather than tear it apart and rebuild it, I coughed up for a SDD 4” kit, with the fiber barrel, lid clamp, etc. Not a huge increase in separation, but it is there. Pretty much the only time I get anything significant past the separator into the bag is when planing – particularly as the can gets past 3/4 full. Matches up nicely with my Delta 50-760 single-stage DC… now I just need to add a Wynn cannister filter!
