By popular demand, I have now developed a series of chain drive drum carders. This will cover all the chain drives: the regular "Finest", the "Finest-doublewide", the 200 series and the 200x2 series. In addition, existing Strauch hand crank chain drive models can be upgraded to the motorized version."Note: the Petite cannot be motorized because it is a light duty machine and not constructed to withstand the stresses imparted by the motor.Being an engineer, I designed these machines to be truly unique in the marketplace and built with the same high standards as the hand crank models.They are "high tech" drum carders having both infinitely variable speed AND reversibility features. The "truly variable speed" feature (not just two or three speed settings) is a God-send when working with fine fibers like alpaca, merino and cashmere.My carders will use very high quality, durable, electronically controlled motors that are made in the USA!. All these machines have been extensively beta tested by some "heavy duty" fiber artists and they all have raved about the design, workmanship and durability.Yes, a 230 volt version is also available to serve the international markets.FEATURES & BENEFITS: * Timesaving; both hands are free to allow the fiber artist to control how the fiber is being carded or blended. * Those with wrist, elbow and/or shoulder issues will find carding with a Strauch motorized machine painless and relaxing. * The ability to card fibers at a consistent and reproducible speed will make consistent batts. Folks wanting to process lots of fiber (i.e.. a cottage industry to make money!) will find these carders remarkable. * The motor and electronic controller were engineered to be quiet, robust, dependable, self-diagnostic and trouble free.
