I'd bet Gass could invent a flesh-sensing system for those presses....

Current interlock switches are supposed to have an anti-lockdown, near simultaneous make feature. If the two switches do not make within a few milliseconds of each other, it does not 'activate'.

I used to operate a shear/press that only had a foot pedal to initiate the cycle. Used to operate the pedal prior to the sheets fully registering. Man ya hadda have good rhythmn to get 'good' parts. The first cycle action was to clamp the sheet in place. Too early and it never got to the stop(bad too short parts), too slow and it delayed a full cycle.

Finally got a chance to look at the video of sawing a curve with a table saw. This is the kind of thing I used to do with my hand held "Skill Saw". Didn't have a saber saw nor band saw so resorted to this kind of thing rather than go with the coping saw. Worked well enough for me, but don't think I'd try it with a table saw.

Think the procedure is called nibbling (sort of).

Moving a saw to wood is a lot different than moving wood to a saw.

It took me a while to find these pictures on somebody's Flicker pages.
I used to put some hours back in the early 1960's on one just like this one. Absolutely zero safety equipment. It sat where a lot of the in-plant traffic went right past it including a small herd forklifts and some nice looking office girls. Distraction after distraction... People constantly stopping to ask about stuff. The shiny handle on the right was the trip and once it started it was going to come down and cut what ever was on the bed. We used them for cutting tightly stacked kraft paper and various kinds of cardboard etc. The only thing that ever made it work hard was a material that was a layer of foil laminated to heavy paper very tightly stacked about 8" high. The bed was around 4' wide. The comb looking thing was the back support for the stack of paper etc. and you moved it forward and back with the hand-wheel at the front below the table. When the stack was in the proper position for the cut you pushed down on the pedal below the hand-wheel and that brought down a clamp bar that sat against the back of the blade and held the stack down tightly to the table. When you tripped the lever the blade came down quick and hard moving slightly to the left as it came down in a slight shearing motion.
The only safety equipment was fear...

I also used a huge old die press (kind of like the one the guy squished himself under in the old movie "The Fly") that had a bad clutch... Sometimes it cycled when you wanted it to and sometimes when it wanted to. I never could convince them to fix it. Today an inspection would have shut them down forever...

"I will bet the girls were paid by piece work. The more they made the more they got paid. "

Nope. They were hourlys. The faster they produced their parts the longer their smoke break without the foreman coming looking for them.

Anyway, this thread was about doing stupid things with power tools and I didn't mean to sidetrack it. Sorry. But people tend to do stupid things around all machinery.

Now there is a town you don't often hear about. You work in the space industry?

How is that for sidetracking a thread? SORRY! I just had to ask.

Yes, I was an electronics engineer for McDonnell Douglas and then Boeing at the space center for 15 years before I retired. We lived in Titusville until recently when we bought 4 acres up here so we could have some SPACE of our own!!
