The Can't Miss Details

The Shopsmith Speed Reducer Allows You To:
• Use Forstner Bits, hole saws and multi-spur or clockface bits to bore large diameter holes without fear of burning your workpiece or bits
• Sand on the Lathe, Disc Sander or Drum Sander without creating unsightly, difficult-to-remove burn marks
• Cut, sand or grind metals and plastics with your MARK V / MARK 4 or special purpose tools
• Create heavy and/or oversized faceplate or spindle turnings using the MARK V / MARK 4 lathe function

Selecting the right tools to do the job is the key to achieving professional woodworking results. You already know that the MARK provides the appropriate operating speed for nearly every woodworking task. Now you can expand its capabilities to even higher levels with the amazing Shopsmith Speed Reducer!

Designed for use on the MARK V 520, 510, 505, 500 / MARK 4 the Speed Reducer provides a 7:1 speed reduction ratio. So, instead of its usual 700 to 5200 rpm speed range, your range increases to 100 to 5200 rpm. As a result, you can now perform even more operations while improving safety and increasing your ability to achieve top-quality results.

With the MARK V / MARK 4 set at its lowest speed setting of 700 rpm, the Speed Reducer output spindle will be turning at only 100 rpm! As you increase the speed of Your MARK, the Reducer's rpm also increases at a 7:1 ratio. This provides new levels of speed reduction for whatever operation you are performing including turning, sawing, drilling or boring.

Now, you can drill metals, plastics and large diameter holes in the hardest woods with the Shopsmith Speed Reducer. Use Forstner bits, hole saws and large multi-spur or clockface bits with improved results, added safety and less burning of the bit or the workpiece. Also helpful for fine sanding on the lathe, disc or drum sander and for large diameter turnings. Attaches at three points to Your MARKs spindle and its two way tubes for vibration-free operation. A valuable shop addition!

Features:
A. 3 Point Clamping (adapter assembly attaches firmly to the quill and around way tubes) for sturdiness and stability
B. Rugged Cast Aluminum Housing For Quality and Durability
C. Reverse Tapered Spindle Flat For Added Safety
D. Internal Mechanisms allow for 100-700 RPM at Speed Reducer Output Spindle (Double Poly-V belt drive system is positive in its action and designed to last)
