I'll never forget driving a 20-year-old, 10,000-lb motorhome down a city
street, pressing on the brake, having a line rupture, and having that
sinking feeling, wondering what I might hit before the thing stopped
rolling.

I had a similar feeling of dread after a ball joint popped on my old
VW Rabbit. Fortunately I was going slow and nothing serious happened,
but it was a sober reminder for me to do better maintenance.


I was driving a water truck, with 1000 gallons of water, 800 lbs of
dynamite on the racks beside the tank and 200 StaticMaster blasting caps
in a box beside me on the front seat, when the right front tire passed
me going down Whitehorse Pass one bright and sunny morning.........

That...was....invigorating.......

That was ... really dumb. Caps and demo don't share a ride.

They often do in the oilfields. That btw..was in 1975. Seismograph
crew. Where we often used det cord to hold luggage and other stuff to
the roofs of our cars/trucks when moving from job site to job
site..often many states apart.

No one thought anything about using a hundred feet of 200gr det cord to
hold stuff on.

Shrug

It is all routine fun and games till something catches fire and
explodes.

It is people like you (generic) which caused Roseberg Oregon to
have some of the strictest laws about transporting explosives inside
their city limits. After a truck loaded with 6 and a half tons blew
up and took out much of downtown. Fortunately, it was in the middle
of the night, but still, it killed a lot of people, and injured a
bunch more. Took out eight city blocks, iirc.

Urban renewal, the old fashioned way ....

Naw..you can burn all the detcord you want and it only burns **** poorly
and stinks.

However Id not suggest putting it on an anvil and bashing it repeatedly
with a big hammer. You have a small but real chance of it popping off.

Its quite safe actually unless its attached to a blasting cap. Then its
eversomuch fun to play with!

I made a fair amount of cash in side bets on cutting down trees and
laying them exactly between markers, using det cord.


For those that dont know about the Roseberg incident in 1959....

Ooh!


As for those of you that dont know about det cord, "primacord"...etc

It doesn't cut nearly as neatly as a chainsaw, but it looks like a
whole lot more fun. What about stump removal?

It cuts, but it would be hard to remove a stump with it unless you were
simply cutting the roots, which require at least one wrap around each
root. Which you can do far far cheaper with a chain saw.

ANFO would be far cheaper and MUCH easier to locate sufficient
quantities.

Reminds me of a story (Any "war story" worth repeating, have
Valuable Life Lessons there in.) of the guys blasting stumps. The one
had a stump with a hole in it, which they proceeded to place the
dynamite in. Boom! Nothing. Added more dynamite this time' Bigger
boom! Only this time, a woodchuck comes out the hole coughing and
chittering "you dang kids get out of my yard and quit playing with the
explosives so close to the house!"
The other one was the last stump of the day, they've "surplus to
needs" dynamite (meaning "more than enough to blow the stump, but not
enough to take home"), and "never can use 'too much'". Touched it off
and "boom!" up the stump goes, and it arches over, and starts the
descent ... and lands, right square in the back of the one guy's
pickup. "Ka-bong!

I'm trying to recall who told me of trying to blast a stump in really
wet ground. Spattered dirt & mud all to heck and back - but didn't
disturb the roots at all.
