Byron, the catch can I am using on my RV6 with a O-360 is a 12 oz metal can
with a screw off cap that is about an inch or so in diameter, similar to a
brake fluid can and attached to the motor mount with a couple of adel
clamps.  I am getting 1.5 to 2 oz of blow-by in 25 hr of operation, my oil
change interval.
Run the oil return line into the cap of the can with a AN fitting and drill
a 1/8 inch hole for a vent.  I use a 3 oz veterinary syringe with a piece of
1/8" od alum tubing to pull the gunk (you would not want this stuff back in
your engine) and measure it at the same time.  I routed the crankcase vent
to 1/4 inch over the top of one of the exhaust stacks to vaporize the
remaining oil mist and heat the vent outlet (these have been known to ice
up).  The air/oil separator is the one sold by AC Spruce.   Steve
