        The damned thing may have a handle on top but it still weighs about
50 pounds with cables, etc. Not my idea of something I'd want to hump very
far from a tailgate so I'm thinking of lugging it on a modified H-F or
similar dolly, but am noodling on how to also carry a small but adequate
compressed air supply. Would like to know what others have done to increase
portability of their heavy stuff.

I scrounged an old Tektronix scope cart once and now I use it to hold my
plasma cutter. Below is a small refrigerated air dryer, still on the same
cart. In the drawer below the bottom shelf go goggles, circle templates,
and bulk spares for the plasma cutter. When I go offsite if they don't
have adequate air, I have an old air compressor on a trailer which I tow.
It's got an 18hp Wisconsin 2 cylinder gas engine and an ancient but still
working Quincy pump.

The plasma cutter and air dryer just sit on the cart. I roll the cart to the
back of my Explorer and lift the plasma cutter into the car, then the air
dryer, then the cart is light enough to lift in. At the other end, I reverse
the process and then roll the plasma cutter into the jobsite on the cart.
If it's impassable (ditches, heavy mud) there are usually framers around
and I grab a couple of them and ask them to hump it in. This is where gray
hair and a respectful attitude go a long way.

        --Well I got the 'gray hair' but I'm not sure I want to hump an 18HP
air compressor around! Was thinking of getting one of those little guys that
carpenters use for nailguns, etc. Not enough air for a long cut but
auxiliary tanks are available and cheap, yes?

I have one of the 'pancake' tank compressors, mine is a Porter Cable,
and I love it for out of shop projects. It is rated 2 CFM at 90psi,
about half of my regular shop compressor but it runs air tools nicely.
Downside is the horrible noise. When it fires off, EVERYONE knows about it.

A two wheel hand dolly has a lot of merit. Add a rack midway up. Put the
heaviest item on the bottom to keep the center of gravity low. Bigger
wheels are nicer than smaller wheels. Figure out something that clamps
the items down for transport on gravel, uneven concrete, and steps but
still lets you remove the items for storage in the truck or shop.

Not sure how many CFM you need, but the very common and cheaply rentable
80cf AL SCUBA tanks are a good source of very clean dry air, and a
standard SCUBA regulator (1st stage) outputs ~140 PSI which will readily
feed a plasma cutter that has an internal regulator for the ~70 PSI it
wants.
