My next project is making my own rotary tool out of an electric hand mixer. Even just the aluminum fan in the mixer cuts deep into wood and plastic with no problem, and has a 5 speed switch built in. The fan in the mixer is connected directly to the motor, on a worm gear shaft that turns the gears that spin the beaters. If I attach a circular blade on the shaft the fan is on, it would spin about 15-20 times faster than the beaters would.
It sounds like a real finger chopper/trimmer to me without the proper guards.

Using an aluminum fan blade spinning at high speed as a chopper could be a real eye opener when one of the fins breaks off hitting him in an eye.
Several company’s manufacture flex shafts that adapt easily to various electric motors the small tools and drill bits require some serious RPM the perfect candidate here would be a high speed vacuum motor that cranks out a whooping 20.000 rpm. Since the vacuum motor is a brush type motor called a Universal motor a simple light dimmer switch would adjust the speed up or down.
A foot pedal from an old electric sewing machine would probably serve two purposes, to control speed plus start and stop your motor leaving your hands free. The sewing machine motor may also be a candidate for the flex shaft adaption.

I owned an old Kirby vaccum and one of the attachments was a flexable shaft that had a 4" buffing wheel. I think I have seen the flexable shafts at harbor freight as well. Mike
Wood spirits carved from pine and cedar knots are some of my favourite carvings.
The knots which are the remnants of the tree limb are removed from a rotting log, pine and cedar are preferred.

Don't gotta be rude about it, here is one that did get beyond the drawing board: http://www.scrapmetalforum.com/made-...ow-shovel.htmlQuote:

Not intended to be rude, just pointing out the obvious.Quote:

The snow shovel was a great idea, shows your a creative thinker however your choice to use ABS plastic was a poor choice for this project it becomes brittle in the cold prone to cracking leading to failure.
A polypropylene plastic would have been a better choice.
Most inventors successful inventions aren't the project they first conceived. Often a great invention comes from an offshoot of the original idea. It's trail and error, remade and refined.Quote:

Hey you're right. The ABS plastic broke down, but not before it got the job done. Still intact, but cracking. I expected that, considering my goal was to use spare items on hand. Also the metal strip I added wore down as well. TBH, most of the time was spent picking through my drawers of screws to find the right bolts and nuts. If my goal was to have the best snow shovel, I would have just used the manufactured
snow shovel in my closet.
You were also correct about this. The fan blade worked great for plastic and wood, but failed miserably when I tested it cutting metal, and broke a fin off. But I know the next fan blade I try will work great on plastic, better than a rotary tool.Quote:
