ADJUSTING THE BRASS GIB

MARK V – MOUNTED OVERARM PIN ROUTER

555970

CAUTION

Before disengaging the Clutch and Handle assembly, always adjust the Depth Stop Rod so it makes contact with the top of the Arm or hold the Dovetail Slide so the Router Motor doesn’t drop and dam- age your workpiece or the Worktable.

ADJUSTING THE BRASS GIB

The tightness of the Brass Gib should be ad- justed so the Router Motor won’t slip and drop abruptly when the Depth Control Handle is unscrewed prior to re-setting your depth-of-cut.

Figure 8. If required, use a 1/8" Allen wrench

to achieve proper Gib pressure.

If it does slip, the Brass Gib is set too loose against the side surface of the Dovetail Slide. To adjust the Gib, use a 1/8" Allen wrench to tighten the four setscrews (26) uniformly in small increments until the proper Gib pressure is achieved (see Figure 8). When ad- justed properly, the Depth Control Handle should move the motor freely without any “slop” between the arm and the dovetail slide.

ROUTER BIT TO GUIDE

PIN ALIGNMENT

When performing pin routing operations, it’s critical that the Router Bit and Guide Pin be in perfect alignment with one another.

To check this alignment, insert a 3/8" diam- eter straight Router Bit into the collet of your Router Motor and tighten securely. Screw the 3/8" Guide Pin into the threaded center hole in the Overarm Router Table Insert. Lower the motor so your Bit is approximately 1" above the Guide Pin.

Figure 9. Use the handle portion of a combination square as a gauge for checking the bit-to-guide-pin alignment at three points, 90° apart.

Use the base of the combination square (See Fig. 9) to check Bit-to-Guide-Pin alignment at three points 90 degrees apart. If the Bit and Guide Pin are not in perfect alignment, front-to-back and/or left-to-right Worktable adjustments will be required.

Front-to-back adjustments are made by loos- ening the MARK V Table Height Lock Knob and using the MARK V’s Table Height ad- justment handles or knobs.

Left-to-right adjustments are made on MARK V Models 505, 510 and 520 machines by loosening the two 1/4"-20 flathead ma- chine screws that hold the Overarm Router
