Cruise control for pedal operated flexshafts.
Most of the restoration work goes on at much lower speeds than the maximum 15,000 to 20,000 most flexshafts operate at. In many cases the penalty for going too fast is a ruined job.
I wanted to make a complete controller for mine that would allow me to set a maximum speed plus other features. I got tired of trying to develop foot dexterity and not have the speed go too high and could no longer wait until I can design and put together an electronic solution. So came up with this quick mechanical one that gets the job done.
I drilled a hole in the pedal and tapped it for 8-32" thread. Used a 1.5" bolt with a thumb nut to lock the setting. It is a simple mechanical stopper that limits the max speed by limiting the pedal travel.
If you have a pedal operated flexshaft tool this modification will make it a pleasure to work with it at low speeds. What used to be a high concentration and high stress effort is now a no brainer. Just press the pedal and don't worry about exceeding the speed limit.

This is a lot like what I did to my (now thirty year old) Foredom. Control is sometimes a good thing.

The guy really is MacGuiver. Seems so simple when you see it though. Why doesn't my brain work like that.

Kidding aside, this is one of the features I have planned for the electronic version. I also want to have constant speed control irrespective of load.
