Circular Saw Blunders in 3-D
I‘m a big fan of stereo photography, so when I was leafing through the August, 1953 edition of Popular Science and a pair of Harvey Comics 3-D glasses fell out, my heart skipped a beat.
What did PopSci choose as a subject to showcase this exciting new immersive display technology?
Circular saw blunders.
So, before you hit the woodshop, do youself a favor and strap on the old 3-D gogs and review these images before something really grisly happens:
I belive that guy’s using a table saw…
I just heard this on NPR today about a saw that detects the difference between wood and fingers.
It’s amazing that it took 53 years to come up with something like this and now the major manufacturers don’t want to use the technology.
Table-Saw Technology Aims to Save Fingers

I believe you mean ‘grisly’, not ‘grizzly’. HTH, HAND.
Chris,
I suspect that the creator of the system owns a patent on it. If he were to get the CPCS to require it in all table saws, manufacturers would have to pay him some sort of fee for using his design. No manufacturer likes the idea of being forced to use something they have to pay for. Also, it says it measures electrical conductance in the medium. This could be a problem when cutting certain conductive materials. Some styles of blades (perhaps diamod edged) might not work with his design as well. There may also be concerns about lawsuits if a brake fails to trigger.
The text is as good as the pictures. Guards that came with saws like these didn’t allow one to make cuts like that. 50 years of torts lawsuits have improved the saws, but the hobby woodworking magazine text is still just as entertaining.

About the Sawstop table saw. You can override the detection circuit by insert a key before turning on the saw, you can then cut wet lumber, aluminum, hotdogs, fingers or any conductive meterials without the brake triggering. The saw also conducts a self-check every time it’s turned on to make sure the safe operation of the saw is not compromised.
We have a Sawstop saw in our school’s shop and it saved some student’s finger just few months ago. I’d rather have a airbag in my car that have a small chance not triggerring then no airbag at all.
Cool stuff . Three D Rules ! My son sent me your link, I am a certified stereo-path. Here’s a mess o stereograms set up for crosseyed viewing .http://www.diamondimages.com/stereo.html
