stuff snipped

The hole won't significantly weaken the house, but it will take forever
to drill vertically through a floor joist or beam, at least if you're
limited to your only flexible drill bit. Don't ask me how I know that.

I guess you found out the same way that I did. I would love to see how an
experienced cable jockey uses those long flex bits because I never did get
the hang of them. That tool you described that applies downward pressure
sounds interesting but it doesn't sound like it was very helpful.

No, it wasn't. It's shaped like an L, each part about 14" long, made
from shiny steel about 1/2" wide and 1/4" or less thick. I think it
has a twist where the bend of the L is. One end is bent back to make
the handle, and the other end I think is also bent back.

Maybe if I did this for months I'd have gotten better able to use the
tool, though maybe not. I think it was just their best effort to make
some sort of tool that might work.


When I rewired this house, I just stuck with 18" twist drills and those
speed auger bits whose name escapes me at the moment - damn - this senility
problem just keeps getting worse! Forstner! At least I didn't have to
Google it to remember. I just read an article that said that older people's
memory retrievals are slower because they have so much data stored in their
head that access time slows down.

Sherlock Holmes said that eventually our brains got full and then
everytie we learned something new, we had to throw away something old.
But I'm not saying he's right.

It doesnt' matter if, judging by phyical brain wrinkles, actual wrinkles
seen during an autopsy, humans only use 20% of their brains, or whatever
they say. Perhaps that is our maximum. Maybe we don't have enough of
some enzyme or other chemical to use the rest. Percent of wrinkling
isn't the only factor to consider.

Another study I heard on NPR says that scientists used to think that
children under 3? were not capable of forming memories, but some study
implied they made many memories but forgot them sooner, that the rate of
forgetting was high until age 6 when it slowed a lot and didn't get high
again until old age.

OTOH, without the ability to forget, we might have trouble finding our
car because we'd remember where we parked it 2, 3, 4, 5, and 6 days ago
as well. And we would perhaps be tormented by every bad thing that had
happened, as well as uplifted by every good thing that had ever happened
to us.

I ended up using my "fox and hound" tester to make sure I wasn't drilling
into a floor joist from above. It mostly worked. (-: The biggest problem
I had drilling from floor to floor was hitting nails. The Forstner bit can
be resharpened pretty easily with a Dremel tool, at least for the first half
dozen nails or so. Then there's not enough left of the cutting twist to
sharpen anymore.

Hmm.
