Hi All,

    Reminds me of a quest they have down here in the hills of W.Va.: 
How to build a 2-story mobile home with portable, in-ground pool that 
can be easily moved from place to place overnight whenever the lot 
rent comes due.;-))))
     I don't think that there's any way around the fact that large, 
heavy objects require large, heavy moving equipment.  A 6" coil with 
RSG, control console, NST farm, toroids, spare parts, and tools will 
pretty well max out something the size of a capped Ford Ranger and be 
loadable by one person. With a 12"-16" 10-20kVA pig, RSG, and a safe 
control console, you're probably looking at a deuce & a half truck or 
a custom built trailer and 2 or more people to load. Bigger than 
that, and you're talking fork lift, side boom, and flatbed or 
enclosed commercial trailer, or a platoon of double hernias. :^((

The whole area of "how do you build a big coil that can be moved
conveniently" is a fascinating one.

By now, it's fairly straightforward to build a pig powered coil with
a 12-16" diameter secondary and having it work fairly well "out of
the box" (assuming you've built a few coils before, and you are
reasonably careful with the models).

The problem is that the thing is going to be a beast, and non-trivial
to move around.  Not everyone has a big panel truck in which to
transport their coil. Although, I have seriously thought about
getting a small trailer to build a big coil on, and then parking it
at a RV storage yard.

So, you look to designs like that one in England that had the nesting
secondary segments, or something that can at least breakdown into
"carryable by one person" chunks (e.g. the OSHA 55 lb, 25kg
one-person-lift limit).

You also want something that won't take 8 hours to assemble, and it
needs to be fairly rugged after assembly.  Say you had your 16"
diameter secondary, and it's say, 7 ft long overall.  You could break
it into 2 foot segments that lock together with some sort of
electrical connector (a sort of nontrivial design exercise in itself)
