Made from carbon fiber and 3D printed ABS plastic, the Martin is a Scotch tensioned electric spinning wheel that is optimized for portability. It is completely enclosed in its own travel case with everything you need to spin ready to go. Martin is capable of 2,200 RPM but is just as comfortable walking and jogging from 300-900 rpm.



Our design aspects are focused around low noise, high performance, light action, and smart ergonomics. Martin is capable of high-speed, light take-up lace work. But it is also capable of high tension/high speed plying jobs. As of July 2021, all bobbins we produce are outfitted with actively cooled aluminum brake drums as standard equipment, so you never need to worry about overheating or wearing out your tension system. The tension also runs perfectly static, where lesser materials will change temperature and therefore friction coefficients, as the spin progresses. Martin uses a braided Kevlar tension belt, which befits the industrial nature of such a robust tension system. Using Aluminum and Kevlar for these jobs was a decision that we are very proud of, in order to give you a tool that is truly professional quality.


As is our standard, each and every component of this wheel was chosen for its quiet operation and endurance. Wear components, including the motor and maiden bearing, are designed to be user-replaceable. Features common to all Daedalus wheels include a hardened tool-steel axle, precision bearings, and a high-quality, ball-bearing, whisper-quiet motor.



Martin has its own internal speed controller, but it can also be used with our existing external Daedalus Soft Start/Stop Controller. This way, you can get spinning on Martin for a lower price than being required to purchase the external controller as well. But even if you have the external speed controller, our testers have found that they enjoy the ability to leave the external controller at home while traveling, to keep things simple. 


Even though Martin can be used without it, our external Soft Start/Stop Controller is a popular choice. You can adjust the speed at 1% increments as well as program custom slow-start and slow-stop delay times, for fine-tuning that high-speed project with gentle startup and zero-backlash stops. It also acts as a remote foot pedal for starts and stops. The external speed controller must be used with a motor extension cable, sold separately (available in 3 or 6-foot lengths).

The following RPM (rotation per minute) stats were recorded from a Martin that had approximately 20 hours of break-in time (top RPM will increase during break-in, which can be upward of 100 hours). Also, the RPM can vary slightly from one wheel to the next, so please use this as a general guideline.
