So the reduction was only meant to decrease the speed of the motor, and the part turned around at a constant speed.
Now we have several types of lobes, we go from 6 mm to 12 mm of lift, and the ones that have that amount of lift tend to overheat quickly on the high point and less on the rest of the lobe. This causes a pretty uneven hardening. > Its a really quick way to heat treat a part! > Indeed, it's beautiful to see how in 7 seconds the part reaches glowing orange. Here's a video of the heater working, I don't recall if I already show this to you guys. https://www.youtube.com/watch?v=RmW3_c0-4Oc -- *Leonardo Marsaglia*. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
