Limiting Foot Pedal Speed on Flex Shaft and Micromotors

by Kylie Jones
Being able to easily control the speed of your flex shaft or micromotor is a skill that takes time to master. Getting a slow even speed can be a challenge. A slow speed is needed for fine finishing of small spaces and details and also when using burs to cut seats for stones.
Instructions
Some micromotors allow you to set a maximum speed on a dial that limits the range of speed of your foot pedal but these are really expensive.

An easy way to limit the speed is to use a physical barrier that limits the range that you can press the pedal.

For my micromotor I found a box that was the perfect height and I just wedge them together using the leg of my table. To find the right height I just tried a few different things like a wood block, a box and even a glasses case.

For my flex shaft I used a plastic screw plug that was just the right height and I stuck it to the pedal base with double sided tape. A piece of dowel would also work well. Even cutting off a section of a pencil will work.

This modification will give you confidence to use the flex shaft for more detailed work and will improve the quality of your work.
