Anyone out there have experience setting the blades on this 6 1/4" Makita block planer? i've had it about 6 months, and this is my first blade change. I cannot get the blades to stay set to the same height. The manual says simply:
loosen the holding screws
adjust the set screws to the desired protrusion
use the triangular ruler to insure each blade is parallel across the length
repeat for second blade
that sounds simple enough, but i've tried it several times, and after setting i had noticeable vibration and rippled cuts. when i'd re-check, the blades seemed to have moved. So i'd reset them, and same thing.
Next i tried to be quantitative with the protrusion setting, so i got a 6" x 8" piece of polycarbonate and can now verify the protrusion on each side using a feeler gage (see picture below). I've set this to 0.003" several times on both blades, used the planar and then rechecked and the protrusion has opened up to as much as 0.020", and not evenly across one blade, nor between the two blades.
this certainly seems like i'm not tightening enough on the 5 holding screws, but Makita specifically says to only use the tool they provide (a hex key with about 3" of handle) to avoid overtightening.
anyone with experience with tool i'd appreciate your insight. you can respond to the forum or contact me directly at [email protected]
