Course, if ya get an ugly bike, (Like mine, 15 years old from Sears) no one will steal it

Il probably will get an "Uglier" bike next time...

And your right those kind of bikes are mean... against your behind

and keep a good look on your Sears, someday some whacko will think thats its a classic and then some other wackho will steal it to sell it to the first whackho

[Bohrn]

rgr that, on the wackos. Yea it could be a classic some day if $99 bikes from '87 ever become liked or something....

Well......there is another way.

He could put a 12v gel battery from kiddy car connected to a pulse generator, wired up to a HEI ignition coil, in the bikes saddle bag. Small & light with lots of run time between charges.

Connect the coil's hot wire to the bike frame with some HEI ignition wire, drop a cheap necklace chain down from the coils ground to the earth. This *should* deliver an 80kv pulsating DC at a few milliamps.

Turn it on and watch the fun when someone touches the bike, especially if they're well grounded by rain

ZZZZZZAP!!!!

All this electricity revenge methods reminds me of a story I heard from my dad;

15 years ago when he was a forklift driver at a sawmill.

The forklifts where usualy vandalised.

All of them but one!

That forklift vas never damaged or tuched.

It was a mystery for about a year untill the driver was sick and my dad was suposed to use that partikular forklift.

He found out the bad way why!

The electric engine heater was badly grounded and put out 230V through the forklift!

The normal driver always started with pulling the cord out so he never noticed!

The vandals never tried to touch that forklift twice!!

Sounds like an experience I had once in the angiography lab, which was a specially modified operating room.

First off let me set up by saying that the floors in OR's are conductive. We also wear conductive shoe covers to disperse static chages.

This precaution was in place because in those days some inhaled anesthetics were flammable, in fact one was a gas called cyclopropane. One spark and you could have your patients lungs spattered all over the walls

Don't worry...they quit using cyclopropane in the late 60's/early 70's.

We also had a 240v portable x-ray unit for times when a patient needed to be evaluated by emergency radiography.

Anyhow.....one day I was there when the x-ray unit was being used and, trying to help out, went to unplug it for the tech when he finished. This things "plug" was huge, about 6" across, metal encased and had a huge handle for pulling it out. I was, of couse, grounded to the floor through my conductive shoe covers.

BAD MOVE!!

The D**N plugs hot lines somehow came loose and shorted to its case. I ended up being the fuse between the hot lines and the grounded floor, or at least I'm told I was

I ended up flying all the way across an 8' wide hallway, slamming up against the wall and being KO'ed. I woke up about 2 hours later in the emergency room with a pulse of about 140 and burns running up both arms and down my right side.

The head electrician walked in and said "whatthehell are you doing still sucking air?!".

No s**t.

Oh dear! But you were lucky.
The technician that used to maintain our developing machine (is that the correct term ) was in fact killed by an accident similar to yours. He was trying to repair such a thing at an other hosiptal and to better reach the rear side he wanted to move it from the wall, clasping it with both arms while his thorax was leaned against the machine - but he forgot that it still was plugged in. So the plug was half pulled out, destroyed and then shorted using him as "fuse".
Now unfortunately those things don't use the usual 220V but are connected to special heavy current lines. He was dead immediately

[KvHagedorn]

Geez Doc.. what sort of amperage was that circuit with the 6" plug? Sounds like you really should be dead.. have any weird tics now or other aftereffects?

[Dr Mordrid]

KvHagedorn;

I'm not sure about the circuit breaker's capacity, but it did blow.

This particular x-ray machine had to deliver full wave rectified DC of up to 120 kilovolts at a half amp (500 ma) to the x-ray tube, often with a duty cycle of several seconds at a pop. Those transformers are huge. This "portable" machine took one large man or two smaller persons to get it moving. Steering was another issue. This was not the kind of portable x-ray machine that you would see on normal wards, it was an operating room system only.

Nope, no twiches or other effects that a couple of weeks off and some burn ointment didn't cure. Scared the s**t out of my wife though!

Indiana;

They are called "film processors", and YES...I know them well.

Setting the WayBack Machine for the early 1970's I can remember learing how to disassemble one from a Kodac rep. just in case we need a midnight repair in the middle of an emergency angiogram

A couple of weeks later I was at Karolinska for a seminar on new angiography techniques and ran into the same guy trying to sell them Kodak stuff.

Small world.
