When having a spare key made to leave with a friend (in case of emergency, or to feed your pets), pick a blank key in a pattern that really stands out from all the rest. Our key, for instance, is Tie-Dyed; the one from our friends is an American Flag.
Then, when you need it back, you can quickly find it in a junk drawer, or on a key rack.
Occasionally you'll need to rebuild something with multiple loose bearings, all of which must be held in place during assembly.
Spray the inside of the races with shaving cream. The bearings will adhere temporarily to the thick goo, holding them in place until the job is done and the shaving cream is rinsed out.
Wet your fingers before removing gum from your mouth, to prevent it from sticking.
Sometimes the vertebral artery can be difficult to locate, but there is a sure fire way to find it every time (providing it isn't absent altogether!).
First increase the color gain and decrease the PRF threshold, to pick up the lower Vertebral flow. Locate the Common Carotid/Internal Carotid Artery Bifurcation, then slowly point the probe back towards the back of the neck. Look for the humps of the vertebrae, and shoot for the line of color between the two humps ... that's the Vertebral Artery!
Want to know if it's going to storm? Watch the birds. If they're flying around or singing, you're fine. When the birds take shelter, you should do likewise.
