Hi again ozhunter
With your three 4" outlets from the 6" main do you expect to run them all at once for one machine like John
If so then three pipes joining at a single point results in more tubulence.
you might be better with two 6,6,4 y,s in series. I just bought some of these reducer Y's at the Perth plumbing shop that Bobl uses. Pretty cheap for Y &postage

Some pointers that might help.
Firstly I cut a length of about 300 mm of 100 duct with a 45º cut on one end - it's bestiof this is longer rather than shorter as you can always cut a bit off later if it is too long.
(there are patterns out there that will do this first up if you want to look for them)
Then I cut bits off around the 45º to help it sit better flush up against the uncut 6" Y.
Final flushing up was down with a belt sander - that way you can get the whole thing nice and flush.
Then holding the cut 100 mm piece up against the 6" Y about where you want it to go I traced around the 100 mm pipe with a marking pen.
Then I cut out the hole a couple of mm inside the line - ideally you need the edge of the hole to curl a tinse outwards for a nice tight fit.
Use a hot air gun to soften up the edges of the hole and work the edge upwards just enough for the 100 mm pipe to go into the hole. If you hit the right temperature the heated edges will be semi-elastic and hold the 100 mm ducting in place.
Then I used PVC strips to plastic weld the 100 mm in place. Unless you have some experience iIt's a lot easier to use something like a hot glue gum.
You had a very interesting and exacting career Bob.
Regards

Yes they are going to be going at once off a bandsaw. What I can procure will probably dictate what I use, I saw a similar thing elsewhere on the forum about using wye's in series. Although I can reuse all the bits I'm buying now, my set up is only a semi-permanent-temporary setup, as we are going to start building a new hacienda later this year.
What options does a mug punter that doesn't have access to a BobL, do to see what air speeds etc I'm getting?
RegardsIf you find you have dug yourself a hole, the first thing to do is stop digging.
I just finished child-proofing our house - but they still get inside.

A cheap indication of airflow is a homemade manometer and then reference to a chart, do a search for manometer in this forum should turn up something.
