    there are some Jokes

    The logic is that one man can impregnate every woman surviving the shipwreck. On the other hand, one woman can only begat a baby once a year even if there are 500 available men. And the 'women and "children first" part? Everyone knows that mothers insist on dragging their kids everywhere...

    I lived my entire life without debt

    In re: equitable divorces... I've divorced twice. I had two children from the first wife. None from the second. I negotiated, and received, full custody of the children in the first divorce since she was wanting to "be free and footloose". She had visitation rights every other weekend and...

    I lived my entire life without debt

    I did not read the whole thread, so sorry if this is repeated. The basic concept of setting aside money in advance is valid, but it is best expressed as "managing a budget." It works differently than "saving money for 60 months to buy a car". Saving is always noticed as a drain on your...

    how many mpg do you get?

    I'm amazed that this thread got all the way to Mid year of 2022 without an reports of more than 50 MPG. I bought my 2017 Prius Prime in Oct of 2019 with about 15K miles on it. Since then I drive it either 1000 or 2500 miles a month at highway speeds (~70 mph) . The car shows that I got 59.7...

    Goodbye OLD CPF Friend From An Old CPF Friend! A Tribute To Greta And History Of A Great Forum!

    Bye Gretta. I was not a founding member, but I recall joining in the very early part of the 2000s. My join date was reset by an inept IT guy who did an update on the software. I really enjoyed meeting all the folks from the Silicon Valley area. They got me into machining my own designs...

    what was the first led flashlight you owned?

    My first LED flashlight was a "pilot's emergency light". It was sold as a light that would not interfere with the pilot's night vision. It was a simple design. A red LED was powered by a watch battery. The LED's leads were the only wiring, and the on / off switch was a simple wedge that...

    Automatic knives, valid for use?

    After reading this thread some months back, I decided to look into a folding auto. I found a SOG TAC Ca Special with the drop-point blade. It looks a bit odd, but part of that is the full sized handle. It looks like you could remove the 1.9 inch long blade and substitute a 3 inch blade. The...

    ham Radio

    There are several reasons for that law. First is the temptation to go to the scene of a crime while it's still happening. You don't want civilians getting in the middle of a high speed chase. Then there is the ability for a scanner to be used in a crime to facilitate the escape after, for...

    Automatic knives, valid for use?

    Like Idleprocess I have a Kershaw Leek. California allows "assisted opening" knives, defined as a design that finishes opening once you open it beyond a certain amount. The design of the Leek is such that it's really easy to open with one hand even if you have arthritis in your hands. I carry...

    darkest place you have ever been?

    I suspect that the official darkest place was in the Grand Canyon Caverns. As others mentioned, the guide turned off the lights and let our eyes adjust for a minute. Then he struck a match. One candlepower is a lot when your eyes have adapted. I was about 8 years old and fascinated by the...

    how many mpg do you get?

    I had my most disappointing mileage last month. I normally can get 50+ mpg on the freeway in my 2002 Prius. [B] Last month I got 27 MPG on a tank of gas[B]. The circumstances were abnormal. It was a 500 mile trip from sea level over several passes that went to 4000 feet and back down...

    Met two CPF members from China today (in Boston/Cambridge Mass)

    It was easier to recognize CPF folks 10 years ago. After all, someone with several expensive lights on their belt was a give away. I met a guy 400 miles from home at a Burger King in the little town of Weed Calif who was a CPF member. He had lights all over his wheelchair. I had a home...

    Do you read the instructions first?

    I'll read the manual, especially when assembling things. There may be a reason that you assemble part C before part A, and it may not be intuitive. But when I read the manual I read the first part closely. If everything they are doing is logical and follows the same general steps it's safe...

    Mini-mod, 18650 into a 3P

    Nicely done. It looks like you threaded on the back side, right? The results are excellent. Dan

    DrafterDan torch, model 12

    That was an interesting video. If you are finding that treading tool has too much chatter, you can reduce the overhang to just a touch more that needed to cut to the depth needed. The shorter the unsupported length, the stiffer it will be. Dan

    DrafterDan torch, model 12

    I was just validating your idea. If you make one based on your design it's likely to be successful. :) Daniel

    DrafterDan torch, model 12

    Yep, that's been done before. The venerable ARC LS had a driver and LED mounted on a threaded heatsink when it was introduced in 2002. I did the same in 2004 for my Slim2 pocket light. I used an aluminum disk for the LED heatsink and the driver was mounted on another. On my light a spring...

    Using LEDs with parabolic reflectors...

    What I liked about the TIR was that you could get a very nice beam in a very compact form. It was nice for a light like the ARC series in the early 2000s. Dan

    Using LEDs with parabolic reflectors...

    An led will work well with a appropriate parabolic reflector. post #25 of the thread https://www.candlepowerforums.com/vb/showthread.php?50720-KILLER-minimag-mod shows a minimag illuminating a palm tree 300 feet away. But read the rest of the post to see how it was made. Dan

    Small Lathe for custom builds

    That's a good point. If you want to make your own flashlights, a light with 7 inch swing and a 14 inch between centers will allow you to make a ton of lights. On the other hand, if you are going to do a production run you want to look at automation. Or at least mechanizing the process...
