Well bike is parked, tender plugged in and bike covered. Done for the year! Son and son in law came over and helped install new over stove microwave. Some of our work is a bit questionable, but is sure looks nice! OK...couple of holes drilled had to be enlarged a bit, but the screws and install hid them!!
Back is sore now...sitting on heat pad and watching my Sparty's take on the Minnesota Gophers. Haven't heard much about the sign stealing wolveriners yet.

Morning gents! It's a frosty one out there.
I dropped this explanation in the thread -
This is the industry I work in. That button, rest assured, is there. It's called a quench. It immediately shuts the magnet down by evacuating helium in an instant. The magnets use liquid Helium which is dangerous in itself. The vent needs to be well away from any area a person could be because it shoots that out and deep freezes anything in it's path. It also displaces oxygen so if the vent fails, and the room fills with helium, it will kill anyone in the room. That happened to a MRI tech not too long ago. Oh, and a MRI is good for 3 or 4 quenches before it's no longer any good. And each quench costs about $30,000 to refill with Helium. And the magnet costs roughly a million bucks. So a quench is a dire emergency situation, which this was.
As far as the magnet goes, there is massive amounts of training involved. The manufacturer (in this case our competition - GE) will spend at least three days training the clinical team. They will drive home the dangers of the magnet and the importance of keeping all ferrous material outside the gauss zone which extends in an oval around the magnet. Then the clinical team should have MRI leads who train others on the risks. Honestly, it takes such a massive lapse of judgement to get a hospital bed anywhere near a MRI that it's shocking to me that it ever happens. The MRI tech must have been away from the room and some numbnutz must have just wheeled the bed in unnoticed.
I've done MRI training of course. It's fascinating stuff. one exercise they do is they have an adjustable wrench on a rope. You hold the rope and as you get closer to the magnet, that wrench really wants to go in there. It's an effort to hold it back. It affects non-ferrous metallic objects as well, but not in a dangerous way. If you take a quarter and set it on end it will act like it's in zero gravity. It will slowly twist around or fall in slow motion because the magnetic flux interacts with the material. Pretty cool stuff.

God help us all meanwhile? I do my utmost best to avoid airports and hospitals these daze! LOL!

I may be a rookie but.
3:50 am started laundry/surfed web/coffee/ took dog on 3 mile walk/ pancakes and more coffee/ vacuumed all rugs/steamed cleaned fake wood floors/folded all laundry/washed area rugs/poop,shave, shower.
I do more before 9:30am than most people do all day.
Now I will have coffee on the lanai before it gets to hot and start another pot of coffee, I might bolt on the passenger foot pegs to my highway bars, they look like they might fit/work I dislike the round highway pegs/bars.
Or I just might sit on the couch and drink coffee all day and listen to POWER METAL all day.
