Victor,

I have four homemade rolled caps that I bought from another coiler.  
They are made from 60 mil poly in mineral oil.  I and the previous
owner used them for a number of years without any failures for
various coils and power levels up to 8kVA.  I am impressed 
by their performance.  The caps are each built into a 6" dia PVC 
casing.  They are built according to Richard Hull's design.
I realize many folks have encountered failures with rolled caps,
but I had good results.  Although these caps have been abused
and survived, I don't advise abusing them.
