Checking cutterhead parallelism. 15. Move the straightedge to the other side to determine if one end of the cutterhead body is higher/lower than the other. (place the feeler gauge between the cutterhead body and the straightedge to determine the height difference.) —if the cutterhead is even or within 0.004" with the outfeed table from one side to the other, skip to step 18. —if the cutterhead is over 0.004" from one side to the other, go to step 16. 16. loosen the hex nuts securing both bearing block studs, lift the spiral cutterhead slightly, then place a shim beneath the bearing block that needs to be adjusted. note: Use the shims from your old cutterhead if available. If not available, newspaper is approximately 0.003" thick and will work for shimming (we don't recommend shimming more than 0.004" on either side, as this may affect how the bearing block seats in the casting). 17. repeat steps 14–16 and adjust if necessary, th...
