9937 Hoffmann MU3 Manual Router With W2 Bit

A V-nail has to compress or displace timber, but the Hoffmann Router routs timber to form a slot in each face of the mitred moulding. Moulded double-dovetail keys are then tapped into the slot for a tight and permanent join.

Heavy duty build for higher volume work. Cast aluminium base with large, ergonomically shaped table surface, precision linear bearings, galvanized steel motor carriage and an integrated motor fine with adjustment. Optional extension tables.

All are supplied with a W-1 router bit, solid tungsten carbide with a life of around 10,000 strokes. W-0 and W-2 are sold separately. Hoffmanns require a standard 13a power supplier and commercial grade vacuum cleaner for dust extraction. MU3P pneumatic models require a compressed air supply.

MU3 is a professional level, manually operated dovetail routing machine. Heavy cast aluminium construction with large ergonomically designed table surface. Precision linear bearings, galvanised steel motor carriage with integrated fine motor adjustment and digital display for routing height and routing location.

Takes router bits for W-0, W-1, and included is a bit for W-2 keys. Also takes bits for W-3 and for W-4 with a bigger motor.

The keyway location is adjusted by positioning the guided centre fence plate on the machine table. The keyway length, the routing height, is adjusted by setting a height-stop rod to the desired setting. On the MU 3-D Digital both positions are shown on digital displays for accuracy and readability.

• Padded hold-down plate secures workpiece and motor switches on

• Pulling further advances the router head until pre-set height is reached

• Releasing handle returns motor to park and cuts motor

• Hold-down releases moulding

Max routing height: 85mm, Max moulding height: 150mm  Made in Germany

How does a Hoffmann Router work?

- Set the router depth using the scale on the MU3

- Position the slot - lay a piece of mitred moulding on the bed and line up the slot location with the indicator on the machine. Slide up and lock the centre fence plate

- Place the mitred piece to be routed on the left side of the bed with the rebate facing away

- To start the machining cycle, pull the lever

- Padded hold-down plate / pneumatic clamp secures moulding and motor is switched on. Continued pulling / foot pressure advances the router head until pre-set height is reached.

- Release the lever to return the router to its home position, shut off the motor and release the moulding. Pneumatic models return automatically. 

- Move the mitred piece to the right side of the bed to rout the other end. Repeat for all four mitred pieces.

- Assemble the frame by placing the first two pieces fast down, inserting the key and tapping it home with a soft face hammer. Repeat to complete the frame
