[Shop-talk] Cutting a chain link fence post?

[Jim Franklin]

I need to cut down about 20 of these a few inches below grade. The catch is they are right next to my neighbor's PVC fence, so I can't get to that side. 

I can use my sawzall but I want the cut parallel to the grade which means getting the entire sawzall below grade and sucking schmutz into the motor. Do-able and at the top of the list so far. 

I was going to rent an excavator (still might) to also remove the concrete blob but then I'd need a bunch of fill delivered (none on site but there may be some when they dig up the driveway to repave it, shelving this idea for a few weeks), hassle factor exceeds the joy of having an excavator. 

Portable bandsaw seems like a useful lifetime tool, especially if it can be mounted vertically to use as a regular bandsaw and also mounted in a chop saw table. Internet isn't forthcoming on the viability of these options. 

Angle grinder won't reach around the back.

Plasma cutter is contraindicated with neighbor's fence. 

Any other ideas? 

thanks,
