The MU2-P pneumattically controlled dovetail routing machine to rout a single dovetail keyway with each machining cycle. Heavy cast-aluminum construction with large table surface, precision linear bearings and steel motor carriage.  For Dovetail Key sizes W-1, W-2, W-3 and W-4 (with optional larger motor).

This pneumatically controlled dovetail routing machine is the more automated version of the MU2.  Aside from the same attributes in terms of design and built quality, the machine features two pneumactic cylinders and a pneumatic foot pedal. One short stroke cylinder is used to clamp the material the instant the foot pedal is pressed, whil a second, larger cylinder is used to move the router carriage up and down.  The main benefits compared to a manual machine are faster and more comfortable operation, more consistent results due to set routing ffed rates and the fact that both hand can remain on the material during the routing sequence.  This is an important advantage when processing longer parts.

Please note: Special $129.00 flat rate shipping (truck delivery) charge is applied for destinations in the contiguous U.S. Extra charges may apply for lift-gate service, pre-delivery notification, residential and delivery to Alaska, Hawaii and to international destinations - please contact us for details.


The keyway location is adjusted by positioning the guided center fence plate on the machine table.  Pressing the pneumatic foot pedal activate the machining cycle:

  • pneumatic clamp secures workpiece on machine table
  • router head advances until the pre-set height position is reached
  • router head returns to base position
  • pneumatic clamp releases work piece

Output is approx. 16 routing strokes per minute, which translates into 2 completely processed rectangular frames. These numbers include material handling, but obviously depend on routing depth, feed speed, material flow and operator performance as well. Flow control valves on the main pneumatic cylinder allow the operator to adjust the upward and downward feed rate independently, depending on the material being processed. On its backside, the large heavy-duty cast aluminum machine base has a 1 3/4" diameter dust collection port to connect a shop vacuum for dust free operation.

The supplied router bit is solid tungsten carbide, made to exacting specifications. Depending on the routing depth and the material to be routed, the useable cutter life is approx. 10,000 strokes. Every machine is shipped with a tool kit and set-up jig, which allows a router, bit change in only minutes. Diamond tooling is also available.
