There I was, planing away, then....
The feed rollers stopped rolling on my DW735. The cutter head kept on rolling but not the feed rollers.
The sprocket for the feed roller just broke. I took it in to be repaired as I didn't know what had happened at the time and I was in the middle of a project. The sprocket was in four pieces.
First time for this - and I've had the planer for 15 years or more.
Now how to prevent this from happening again? I never plane more than 1/16" at a time.
