    Old Publications & safety

    I took my driver training class in 1959. The car that was used was a 1958 Ford and it had seat belts. I don't know if the belts were available on all Fords of that year or just the school's option to protect the instructor.:o

    An idea from a woodworkers catalog that may call attention to the presence of this hazzard is available from Lee Valley. Their version only fits chucks from 3 to 6 inches diameter but you could enlarge ihe idea to fit larger chucks. Not much padding but it will make those protruding jaws more...

    Why the advertisements?

    I was having this problem until I cleared all my cookies from the computer. Now with the new batch of cookies the log on problem has disappeared.

    I hate plumbing!!!

    Plumbers, electricians and other tradesmen all have two advantages over us. First they have the knowledge coupled with lots of experience about what is needed to make the repair and secondly they have the necessary parts in their trucks and don't have to make repeated trips back to the home...

    Oh Yes! I like it. I also liked the videos of your 3D printers in action. The high speed photography shows things that occur too fast to register in our brain when viewed in real time.

    Looking for 500 lb chain fall found article!!!!

    Swede, I think you are looking at this system backwards. The closer the two joined pulleys are to the same size, the greater the mechanical advantage. You have to move a lot of chain to change the elevation of the load a small amount but the effort required to raise the load will be a lot less...
