In my never ending search for interesting bits of salvage (kind of my hobby
now - well one of them) I decided to break up the big pieces of concrete
that were used as intertial dampers in that washing machine I tore apart a
couple weekends ago. I'm no stranger to using a 10lb sledge (although not
much in many years) nor a 3lb sledge. My hammer of choice most days is a
2lb machinists hammer or a plastic dead blow hammer, but I've been known to
pick up the 3lb sledge to beat a part into submission.

Anyway, I took a couple blows at the concrete with 10 pounder and it was ok,
but I just didn't have the control to deliver power vertically to the pieces
while standing. I found that kneeling down on the floor I didn't have the
balance and comfort to throw that long handled ten pounder around as easily
as when standing. So... I picked up the 3 pounder I keep hanging over the
back work bench next to the other hammers and gave it a couple whacks. The
concrete broke nicely with little fly away and I quickly exposed the small
web of... 1/4" rebar welded to the bolt plates embedded in the concrete. I
didn't even know they made rebar that small.

So for those who would seek enlightenment. No. The answer is not always,
"get a bigger hammer."

Maybe in the next weekend or two I'll make some mini tongs out of that mini
rebar. LOL.

You may..may have moderate results with Bulleye powder..but most
smokeless powder will NOT work for explosive use. Its a controlled
burn exothermic compound and unless you can contain it with a
plug...tightly and strongly..it will simply burn after pushing the
clay away.

Black powder..will work somewhat better..but it too needs a good solid
and snug plug.

Now you can make a decent low order explosive by mixing fertilizer
with diesel fuel..but now you need a blasting cap of some sort..which
can be made from ...well...its on the net.

little carefull aiming I have blown the side out of cans quite

inch high whereas mine reduces them to a quarter of that.

I've always found that a fascinating concept. Want your building's
foundation stronger? "Reinforce" it with some mystery metal which may
fail at any moment. I never got into any large concrete work, so I
never needed to know grades, but there are some. We mostly see the
cheap 40 rebar in building supply places. I mostly used it as stakes.

I have always had pretty good luck welding up things from rebar. As I remember some rebar is certified for welding and some is not. I may have just been lucky, but that is my experience.

Cheap stuff - works well enough as tent stakes. Unless you are
used to it, use the 3# sledge instead.

Maybe in the next weekend or two I'll make some mini tongs out of that
mini rebar. LOL.

The only thing that should be made with rebar is reinforced concrete.G
It's such a mystery metal that you have a very good chance of wasting
your time.

I've always found that a fascinating concept. Want your building's
foundation stronger? "Reinforce" it with some mystery metal which may
fail at any moment. I never got into any large concrete work, so I
never needed to know grades, but there are some. We mostly see the
cheap 40 rebar in building supply places. I mostly used it as stakes.

Yes, that's what they're using in the spillway.

A man called Juan Browne, C-130 and 757 pilot, has a series on the
rebuilding of the Oroville, CA dam emergency spillway, so I've been
watching the detailed series with fascination. Highly recommended.

questions for the construction and regulatory guys, disses the MSM
properly, and includes his kids, teaching them all sorts of things in
the process. We have an earthen dam 50 river miles above Grants Pass,
so I have a slightly stronger than usual attraction to this. 66 videos
about it since Feb of this year when it crumbled.



Then there is the backyard slab of cement type. It contains sinks,
iron, steel - whatever is left in the kettle.

Yeah, that's the stuff you don't know if it'll bend or not.
