  1. I've considered asking permission to swim that quarry, since it's all private land around it. It didn't look clear enough to do what I want to do.

     

    I've also considered diving at night.... but only during a full moon in crystal water, at a place whose bottom I was very familiar with. I wanted to do some photography, but didn't have a buddy to go with me, so I stayed in bed.

  3. Gilboa is over 100', you better have 5m or better wetsuit because the water at 100 is around 50 degrees.

     

    I've swam in 45deg water with no suit.

    .

    .

    .

    .

    For about 5 minutes.

     

    Being that I'm freediving, my total time-per-dive at that depth would only be a few seconds. Cut that in half and I'll be able to hang around for half a minute or so.

     

    I've tried freediving in a full 5mm john-jacket a couple of times and I really hated the way it felt. The act requires much more articulation, and fighting the suit wears you out sooner, requires more oxygen. Plus, 20lb of extra lead to counter the suit makes for a lot more inertia, more extra work, and more O2 consumption...

  4. Thanks all for the tips! The stuff up in NW Ohio, I already knew about, and it looks completely bad ass. I was looking for something a bit closer to my babysitting source, because that will increase my ability to go. Looking for legal stuff, places that have been cleared and aren't creepy as hell.

     

    Anybody want to do a Dive Weekend somewhere? Those places up in the NW have campgrounds.

     

    Learn the signs of actual drowning (not tv drowning) before you dos this.

     

    Many thanks got the concern. I actually have done quite a bit of training to recognize what's going on with my body at various stages of apnea, well past the burning sensation in the lungs, past the belly convulsions, all the way to tingling in my extremeties... in the safety of my livingroom. Personal record for holding is just shy of 4 minutes. Depth record is 50ft, and I'm able to hang out down there. I need a deeper swimmin hole. :)

     

    Here's a vid I took playing in 40ft of water:

  5. I've gotten into the freediving thing, and I'm looking for clear, deep water to practice in (without having to go to lake Huron).

     

    I know there are some great ones in northwest ohio, but there are a shit-ton of limestone quarries around here, there's got to be one somewhere close. I'm looking for 60ft deep mininum with good visibility.

  6. but why not get something better than the bottom line product?

     

    Because it's not a value-added expenditure. If you just love riding, then find a bike that doesn't hurt and ride it. Extra thousands of dollars for those conveniences could be much better spent.

    A girl I was dating a couple of years ago was like that. She'd bitch and moan about having a bunch of comp time and not being able to afford to take a vacation and use it... because she'd just spent $3000 to buy a bike and get it fitted. She did exactly one charity ride a year and never placed north of mid-pack. I asked why she spent that much, and she gave your reasons. I pressed her, why did she neeeed that stuff?

    Her old bike made her thumbs numb.

     

    Dumped her a few weeks later. Don't need no woman who makes those kinds of financial decisions. :p Also, she sucked in bed... or didn't... you get it.

  7. It think I was 10 the first time I put 1000 miles on a bike in a summer... maybe 11, not kidding.

     

    People spend a shit-ton of money one this stuff, and I swear to Ronnie James Dio; I don't see why unless they're competitive at a top-10-in-your-class level. Overweight sloths on $3000 bikes are a common sight around here.... sorry dude, that extra 130% you spent on all that competitive advantage ain't going to make you any faster.

  8. Basically, yes. The first hurdle is making the eccentric shaft. From there, make a long ass fuel rail and then get it all to work together after you get the 16 dowel pins to hold it together.

     

    Nooo that is far from the only hurdle. ;) There's a very good reason that there are almost no rotaries over 3 and 4.

     

    Each rotor can be an engine unto itself, getting 6 of them in time with each other is excessively difficult.

     

    Even if you can do that, you have to hold it all together. Just looking at some steel on steel on aluminum, you may assume nothing is moving. It is all moving, by thousandths and tens of thousandths of an inch. As you stack things up, the possibility for destructive gaps and misalignments increases.

     

    The real bitch: Resonance. Note that those guys only BRAP the engine and never wind it out. An engine that long, and eccentric shaft of that diameter, it's all going to resemble a jump rope spinning around when it really winds out... on a small-to-the-naked-eye scale, but enough to stress things that don't want to be stressed.

     

    You can tune and split hairs to reduce imbalance, but you never eliminate it. You can make you parts out of the baddest ass metals available, but they'll all still flex. In the end, that engine will meet the same fate as every other hyper-rotor engine. It will go boom, it may even snap in half like the titanic. There's a reason that Mazdas very well funded racing effort of the 90's didn't go beyond 4 rotors.

     

    I'll accept that metals have come along since then, but not that far. I doubt that you can spec a bolt that's long enough to hold the stack together AND resist the forces trying to rip the engine apart. Hell, a 4ft long bold will change dimensions and grow on it's own as you heat it up.
