If the video doesn't start at 38 minutes and 30 seconds then jump ahead to that position.
Watch for at least 2 minutes.



Quick Recap:

Dozens of dremel related failures. (Unsure if the failures are motor or flexshaft related).
The pedal control will make it easier to keep your bits cool, prevent you from splashing the cooling fluid everwhere.

Thank you for this information, might have to look into one.

If you're on a shoestring budget and want the option for a foot pedal on/off, I bought a 12 dollar sewing machine pedal that I plug my dremel into. Its just on/off, no variable speed based on your pedal position but it was only 12 bucks too.

Nate I want to thank you for posting all this! I re-watched Ron's training vid. With that and what Dan Merrick just posted, it made me re-think my technique to realize why some of my Grooves have had that Cave Man quality! Gonna alter my technique again. I knew you would be a sharp Gadgetman! And that new Dremel Fortiflex looks awesome...

Keep at it.
