Video: Remember your high school DT teacher’s non-stop litany about safety? Here’s a real-life example of why you shouldn’t goof off with power tools. Taking a break from smooshing stuff, the folks behind those hydraulic press videos attached a bicycle brake to a lathe to see if they could bring it to a grinding stop. Nope.
Not only were the disc brakes completely ineffective against the whirling power of the lathe, they melted and caught fire in the process. But thankfully, stuff getting destroyed is still captivating to watch.
