Safe?

Keep in mind that the Shavings Magazines that featured the flexible shaft also show the Mark V in drill press mode ripping 8x4 sheets of plywood.
I hooked up one of those shafts once and it did a crazed snake impression. Went out and bought a Dremel.

Just to be clear, someone put a saw blade on while the Shopsmith was vertical and pushed the wood past the blade (I assume the wood was on the floor)?

Hmmmm, now that's a thought?

Flexible shafts are like Corvair's, "unsafe at any speed". Probably why they are seldom seen anymore.

I have used high-speed (400,000 RPM) dental type flexible shafts and they work great and are extremely safe. You can engrave an egg without breaking the shell. I agree anyone trying to put a 10"+ anything on one, like shown in the old Shopsmith picture, would scare me to death.

And what happens when the wood on top of the blade pinches, stand clear.

Flexible Shaft by Shopsmith

My Shopsmith flexible shaft arrived today and, as we've come to expect from SS, boy is it well made! This is by far the most heavy-duty FS I've ever handled. It's beefy! This should work well for my intended purposes, and don't worry I intend to stay safe! Here are some shots of the ends...

Note the lubrication fitting over the bearings... nice!

Sorry I was out of touch for a bit. Yeah, that's exactly what they did. Saw blade was parallel to the floor and they were using the ground as a 'fence.' If you ever get a chance to check out any of the really old Shavings magazines there are some pretty funny things in there. One had a picture of them using the SS as a mixer, like for drinks or mashed potatoes. Standing there in drill press mode with a whisk looking thing hanging out of the drill chuck.

The picture in this thread, with the guy holding the whole surface of the disk sander flush to a board, is right up there. I wouldn't want to be in that room when they switch that on.

I tried that manuever with the sanding disc today without trouble or unacceptable danger. As long as one keeps a good hold on it, it works just fine. I image the drum sander would be quite handy with the flexible shaft. I do not believe that the flexible shaft is an unusually dangerous tool. Alec

The dangerous comment was around the use of a flexible shaft with a saw blade on it:eek:
