J. Phil Thien's Projects

Thanks, I went to HD earlier for some 4 X 24 aluminum vent tube.  Cut about 8" off the crimped end of each.  Combined the two pieces, then cut it down to the diameter to fit inside the flange.  Taped it with some aluminum vent tape that I had.  Was planning to pop rivet it, bit tape is working well.  A little hot glue to hold it in place.  So working well it seems. 

Thanks, so I'm clear on the need to drop the outlet pipe into the baffle area.  But when you say half the Inlet diameter which inlet are you referring to. 

I should clarify, I have a 4 inch hose feeding into the drum.  And a 5 inch outlet feeding the dust collector.

Did you mean inlet of the drum or "inlet" of the 5 inch flange?, (inlet of the outlet pipe?). So should I drop a pipe 2 inches or 2.5 inches from the baffle?

New to the Thien baffle.  Built my first one this past weekend.  I used a 30 gallon fiber drum and 1/4" Birch plywood baffle.  I used a 5" flange connector from Oneida to connect the drum outlet directly to the DC, a Delta 50-760 (which has a 5" inlet).



My question is about the inlet of the outlet.  This question was asked in another thread, but no answer was given.  My question revolves around the inlet to the 5" flange.  Many people use a 4" outlet connector, and that 4" pipe protrudes inside the baffle area.  My design does not.


I have an idea for a short piece of duct from HD that I can add, but don't want to do it if it adds no value.  So far the baffle is working well.  I dumped out a cubic foot of dust that I had and there was maybe 1/4 cup of carry over.  And some of that may have come from the dust bag.  Does the design need/require that the outlet tube protrude down into the baffle area.  If yes, how much?  I've seen some with protrusion and some without. 

Also I installed a Wynn filter this evening.

New to this group, been away from woodworking for a while, but starting up again.  I have a Delta 50-760 DC with 5 micron bag.  Now that I'm starting up again, I'm upgrading my DC.  I had a 35 gallon fiber drum that I wanted to use as a separator for many years, but never set it up.  Then found the Thien baffle. I had a couple of 4" connectors from Rockler, but never used them.

After discovering the Thien, I bought a 30 gallon drum, installed a baffle and mounted the drum on the cart with the DC.  Will post some pictures.

Next upgrade is to add the Wynn 1 micron cart.  Hope to have it this week some time.
