J. Phil Thien's Projects

Thank you for your patience r2,
I obviously haven't a clue what I'm doing here.
I don't care if it's a 2h or not,,,just throwing numbers out.

This is why in one of my first posts I said there should be a sticky post listing factoids
For example, almost everyone is using either an aluminum can or a 20 or 32 gal Brute,,, shouldn't there be a wealth of numbers relating to these?

ok, i figured that was coming.

I deliver to an HVAC place and a sheet metal place, I'll have to ask if they can make me a transition around  4" round to 8 x 5   12" long.

So if I do this on a 32 gal Brute the lexan for the th would be roughly 72" long?
Where you all order that?

If I went with a 2H, would this 3-1/2 x 10 transition to 4" range hood transition be useable or is it too narrow?

What is the circumference.. or should I say length of the lexan piece?
Not exactly,, for purchasing estimates.

When you all are talking about 4,5,or 6" duct size being best are you referring to fixed duct work?

So if I plan on top hating my brand new HF and manually attaching 4" to one maybe two machines over pretty short runs I should be sucking my socks off right?

Hmm,

Ok, lets try this ONE question.

If I am going to go top hat/ 4" in and out/  what should the height of the top hat be?

Hello,
I just ordered a HF dc and want to make a separator. I'm not trying to re-invent the wheel. I would like some kind of separator, and plan on getting a Wynn filter after the separator is established.

Just going to throw out some questions and see what I get for responses.
Anyone i.e. Phil, ever think of making a sticky post that just has facts/absolutes/reference numbers... stuff like

Quotemouth position relative to the baffle -Phil's testing suggests the position to be 1/2 the pipe diameter

.
Just as a reference guide for the newbies.
---What's the height of top hat with 4"or 5" outlet?
---I'm not sure if I should go 4" outlet or 5" outlet on the HF
( I currently do mobile connections to table saw, jointer,bandsaw,thickness planer. In current shop I cannot do fixed piping.)



Am I correct that this site heavily leans towards "top hat" design and not "in the bucket" design?
Why?

Some of the designs I like are retired2's

Q: Is the square to round duct custom made or off the shelf?


This seems to be a perfect off the shelf solution to a bell fitting.

It looks like the connecting ring

Would allow adjustable height connection to the port tube

Ok, what about a direct mod of HF like this?
https://woodworkingweb.com/creations/59-harbor-freight-dust-collector-conversion
I like the way this keeps the setup mobile and relatively compact.
(I read somewhere questioning the safety of flipping the motor and impeller from vertical to horizontal.)

Again, just trying to improve my dust collection, not trying to perfect it.
( Right now the shop runs a 20 year old Grizzly 1hp that has never had the top bag replaced,, it puffs when u turn it on)

Sorry for the rambling...

Thanks,

Hello all, first post.
  I've been lurking for awhile, and want to start a cyclone. I just ordered a HF 2hp dc. I plan on getting a Wynn filter after making a top hat. I like the top hat design because I think it looks cool to see the cyclonic action. And I seem to have landed here at "retired2's" version.
That said, my brain is about to explode with information overload!
I'm sure most if not all of my questions have been asked, but it's easier to ask again than search thru the mountain of info on this website.
ok, please bear with me,
1)I can somewhat understand the concept of the importance of widths, measurements and lengths inside the cyclone,, but why is it better for the bottom piece to be thin? Why not 1/2" and bevel the edge?
2) The conversation on  Elliptical Bell Mouth Templates really makes me want to do something else, :-\

Has anyone made any kind of a list/cheat sheet with all the do's and don'ts involved in building a cyclone?
I understand how people can get obsessed with wanting to make the next one better,, but I just want to cut down on some dust I'm eating.

Thanks all.
Mike
