I think you're right dbhost.  1/2 it is.  As for the fittings, I found some 3" fittings at Home Depot (I think it's 3" and the color is black).  The outside diameter is 4" and the inside is 3.5".  I got the 45 degree fitting that will be connect with the 90 degree fitting through a short 3.5 straight tube that you can buy in a 24" length.  This is for the intake.  And for the out port that connect to the dust collector, I use the same 3.5" tube connect to a coupler which connect to a short 4" flex hose and this short hose is connected to a 4 to 5 inch adapter that connects to the dust collector.  You can get this 4 to 5 inch adapter at woodzone.com

Thanks Phil and dbhost
I measured the trash can again to confirm that I have 18" outer diameter and 17.25" inside diameter and this is what my lid will be for the 20 gallons.  By placing the center 4" hole at 9", I will have 2" between the two 4" holes (9" center + 2" radius + 2" separation + 4" hole + 1/4" = 17.25).

Thanks DBHOST,
I already have a 30 gallons that I made for both Delta 50-760 and the shopvac.  For using with the shop vac I just use a 4" to 2.25" adapter.  What I want is to be able to fit the trash can underneath the dust collector using the 4" hoses.  Because the diameter of the 20 gallon trash can is only about 18", I have about 9" from the edge to the center to cut out 2 4" holes.  And this is what my question is all about.  Would it work if the separation between the 2 4" holes about an inch apart?

Hi Phil,
I have a Delta 50-760 dust collector and currently use a 30 gallon trash can with your baffle.  I want to place the trash can under the dust collector but the 30 gallon is just a bit too tall to fit.  I got a 20 gallon metal trash can and want to make a lid for it using the 4" dust port from Woodcraft.  Do you have any suggestion on where the holes can be for the lid?  The diameter of the 20" trash can is about 18.5".
TIA
Mike
