J. Phil Thien's Projects

I started with a 2.5" port at the bottom of the wheel and enlarged it to 4". It works well, but could use some at the throat as well. However after reading retired2s post I may just leave it.

Hi All,
I made a video of the sawdust flow in my table saw, with the goal of improving dust collection within the saw. I did this with a clamp, camera phone and a camping headlamp. Took about minute to set up.
I am getting too much dust out of the top of the saw (no overhead collection as of yet) and think there can be some improvements within the saw.
I am thinking a bit of a wider internal cover and possibly moving the hose to a flexible internal position.
Has anyone done this, thoughts?

Nice job! My next one will be a 5" with fectangle inlet for my delta 750-60

What do you do when you need to make really fine cuts ,narrow thAt is....
Very nice design

I agree :)

Some very nice work on the dust hood.  I am getting done with my phase 1 dust collection. I will post some Picts soom

I really thought this article in the first post was great! It really showed that some systems cannot support 6" ducting and the bell mouth fitting idea is excellent.
I am in the process of building my 1.0 DC system with a delta 760-50 with 4" pipe and will be trying some of these flares to optimize my system.
:)

I read the article closely and do agree in theory and Bill Ps article that 6" is best. However several of the machines that supported 6" inlets were incapable of meeting min air flow.  That being said given the data provided, I think 5" will work best for my system. I can source it here in Atlanta and can have it custom made in spiral or 26 gauge pipe for a reasonable price compared to plastic.

Thanks for good feedback!

Ok everyone,
I found this article http://www.portercable.com/uploads/PCD/Documents/News/182DustCollectors.pdf and it answers the question of whether my DC will support a 6" or 5" ducting. Based on my reading, it seems best to go with 5" ducting.

Hi All,

Have been researching this site for optimal thien dust collector design. I kinda stumbled onto dust collection and the important health benefits on other sites.
I like one of the hat designs some has posted on here (side intake with flat bottom rather than sloped) and will be incorporating it under my motor on the frame.
I have a small shop in basement with the basics, table and band saw, lunch box planer, drill press and router table. I was planning on running 6" main (18') with y's running to 4" ports and short flex hose runs to most all machines. I also have a overhead jet room filtration system as well.
There has been a few comments about 4" vs. 6" port size for this dust collector and possibly 4" might be better. I know the entry port to fan/impeller is 5" and there may be a possibility to get 5" tubing throughout. Obviously, 4" is easier to source, but I have one source locally for 6" as well.
My question to the group is what main size should be used with this system 4" main, 5" main or 6"?

Thanks,

Andrew
