i bought a HUGE set of bolt cutters from harbor freight for 20 some

whips as

simple as pinky pressure. highly recommended

The approved method is to file a notch at the cut point using a

triangular file or grinder. Then clamp the rod in a bench vice with

the notch right at the top of the jaws.

Then using hands or pliers, rock the exposed rod back and forth.

Just a few bends and the rod will snap right at the cut.

Paul, KD7HB

Paul is right. A lot of antennas are 17-7 steel. There's no way any

resonably priced cutter will slice through even a thin piece of that

without nicking the blade or cutting surfaces. But it's brittle and

can't take a sharp radius. Put it in a vice and file a notch from

two sides. Doesn't have to be a big notch. Then move the notch to

right next to where the vice clamps it. Grab it with good pliers and

force a bend at the notch. It should snap pretty cleanly and only

require a little bit of filing to clean it up.

I HAVE had success with those 'fibre' wheels for the Dremmel tool as

well, but it will probably cost you a wheel.

Another trick... Straighten out a wire coat hanger and cut it to the

whips original length. Then sand the goo off one end so it makes

good contact to the metal and put it in the antenna base the whole

way. Then start tuning that by clipping off the top in 1/4" pieces

until you pass the minimum. Take it out, lay it next to the steel

whip, and cut the steel whip 1/4" long for a good starting point

instead of trying tomake a bunch of cuts.

Sawzall

sawzall blades are not hard enough..... have to use either a grinder or

a file corner to nick it, then snap it off. A grinder will make short

work of taking the sharp edges off.

Last shop I worked in we had a tech that used the Dremel to cut small

bolts (machine screws?). He said the bolt cutters in Klein strippers left

too much slop behind. He was fired soon afterward.

me thinks a plasma cutter would be the only thing that can do the job...my moto "if it is good enough for blood!"
