  1. Look forward for seeing the end results.

  2. Why 6″ to 4″? Would it be less expensive to stay with 4″ and reduce at collector? Thanks for sharing.

  3. Great as usual!

    Pipe fitters use a strap to mark a line around a pipe. I use my miter saw to cut pvc pipe it makes a good square cut. Good video on your installation.

    Anthony, I will be pleased to respond to your question, but you have to “enable” responses to your comment in Google+ or in your YouTube settings… I think ūüôā
    There is no reply button after your post.

  6. i think i have it I’m new to this whole social media thing

    +Anthony Patrick¬†Excellent… The reply button is working now. ¬†I don’t always get the social media stuff either… It’s just I’ve had this problem before so knew the answer…
    I live in Wisconsin, and it gets pretty cold here. ¬†I can’t imagine that the dust moving through the pipe, even in an unheated space, could build up any significant condensation. ¬†As far as dust build up, my piping runs straight up to the second floor and it has never clogged or accumulated dust. ¬†Of course it is always a good idea to run the dust collector for a few seconds after you shut off the machine you are using so that the lines clear. ¬† Actually, I think your plan sounds great.

  8. Thank you for your response I find all your videos extremely informative I especially like the detail that you go into and the fact that you explain the “why for” aspects simply because I don’t easily except the just because aspect if that makes any sense at all if I’m going to do something I want to know as much as possible about what I’m jumping into that’s why I love you tube my wife accuses me of researching things to death lol but I love her anyway

  9. i always use electrical tape to make pipe slightly larger

    Pipe fitters use a heavy paper product/tool called “Wrap Around”, for laying out pipe cuts.

    +Kenneth Sternberg You are so right. We a a few of them in different sizes.

  12. Nice work! The dust collection system at school isn’t so good and my tech teacher could use alittle help. Lucky I found this serise of vids to help her ;D

  13. Thanks for the informational video. The excellent audio quality makes your video easy to watch.

  14. Thanks Steve!

  15. I learned a lot. Thanks.

  16. Groovy music

  17. Make a small hole in either side four line and put a bare copper wire inside no need to be thick and ground that wire.

  18. Incredible contributions; very grateful, indeed!

  19. very well done sir, GO PACK GO

  20. Where did you obtain the hangers shown in the beginning of the video?¬† Plumbing up a new woodshop and have been looking to some type of hanger for the 4″ PVC.
    Thanks

    Those came from the same plumbing supply wholesaler where I got the pipe and fittings… however, I have since seen them at one of the “big box” stores. If memory serves me, at The Home Depot. Thanks for watching!

  22. Thanks,

  23. Gaffer tape also works really well for snugging up pipe fittings.

  24. downtoearthwoodworks

    Every time I think about buying some “gaffer tape” I can’t seem to find it anywhere except at an online camera seller, and a roll of tape is not enough to make up an order… at least to get free shipping! I wish someone sold it locally. Anyway, great idea!

  25. I really enjoyed your presentation. Wished I’d seen it before doing the same in my shop. But, I still learned a lot. Thanks.

  26. Steve, apologies if my question is answered elsewhere but I couldn’t find it. I notice you use a remote switch to turn on your dust collector. I’m looking for such a switch but most seem to be rated only for lighting circuits and not for heavy duty inductive loads such as a motor. Could you let me know the spec of your switch and where you sourced it from..? Thanks in advance.

  27. downtoearthwoodworks

    Simon, the remote I use came with my dust collector. There are third party remotes that have higher ratings than the basic household type. Highland Woodworking sells several different versions (110 volt, 220 volt, etc.). Here is a link to get you started:

    Take care and thanks for watching!

  28. Thanks for the tips.

  29. 4″ has an area of 12.57″.6″ has an area of 28.27″ That is a huge choke point and will kill your CFM cutting it more then half. Why do the machines use 4″ ports? Thats the way it was in the 1800’s so why change is their motto on every thing. Not much innovation except for SawStop. Asia just copies the 1930 unisaw. Dust colection for the hobby shop is only about 25 years old. Wait a couple of hundred years and it will still be 4″ me thinks. The popular HF 2 HP DC flows 600 CFM with a 5″ hose. Put a 4″ hose on it and it will be less then half of that. I had to change the ports on my machines to 6″. It was asy and looks like factory made. Never use 4″ on anything even if you have a 5HP DC.

  30. 4″ has an area of only 12.57″, 6″ is 28.27. Want to kill your hard earned CFM? Reduce the 6″ to 4″. You need to get some test equipment and a copy of AMCA 205 on testing before misleading people.. For the Hobby guy keep 6″ duct all the way to the machine and put a new 6″ port in for anything large then a 12″ impeller. As an example the 5″ HF unit flows 600FPM with a 5″ hose. Put in 4″ duct work and the CFM drops to 117 CFM. That info is not from me but from processional Engineers in the air movement business. Ansi /AMCA is similar to UL except its for air movement instead of Electrical. For testing the Standard is a Pitot Tube. You cannot use an anemometer used for wind speed. Read Bill Pentz. You have very bad data.
