Not a problem his projects never make it beyond the drawing board.

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.

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

Also there are many little projects I don't post here. https://www.facebook.com/killyrtv/po...98?pnref=story

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

You post a DIY project with no follow ups

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.

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.
