This isn’t a Shapeoko specific question but I ran into an issue today where the removable blade on my Amana RC-1148 v-bit came loose twice.
The first time it came loose I could tell something was wrong because it started burning the wood and sounded oddly loud. I quickly shut it off, cleaned everything up, retightened the blade, and ran the job again on a new piece.
I could tell something was off right away as the router sounded louder than normal. After just a few passes, the same thing happened. I could see the insert blade was off by the circular cut the bit was making in the wood. I quickly shut everything down and sure enough the blade had come loose again.
Has anyone run into this before? Do you have any ideas what might be causing the issue?
