I turned on my CU300 with the main blade tilted to 45 degrees and the scoring blade fully extended above he table. It appears the belt driving the scoring blade broke. At least the scoring blade doesn't spin any more, but I haven't taken the cover off yet to see what the exact problem is. The 12" blade still spins correctly.
- Is this to be expected, that you can't tilt and operate the main blade when the scoring blade is extended?
If so, that pretty much stinks. I always use the scoring blade, it works very well even on hardwoods to eliminate tearout on the bottom of the cut. No need for a zero clearance insert, just use the scoring blade...
