Hello All,
I finish 2 of the 3 caps this weekend and had a couple of questions for
those who have been there before.  I added the oil and pumped on the cap
with a refrigerator compressor. The oil foamed quite a bit and I had to stop
pumping a few times to let it settle down. The Kraft paper seems to hold air
in small spaces and generated tiny bubbles (foam). The trapped air seems to
be diminishing and I hope to use the caps soon. How much pumping should I
do? One problem is the terminals through the sides of the PVC pipe leak so I
have to continually pump to keep a vacuum. I haven't figured a way to seal
them although they don't leak oil. By the way 25 in-Hg seems to be the
limit, does that sound about right? I will hall them into work tomorrow to
check the capacitance on our fancy C-meter.
More to come...
