Hmm… I fed 12” wide green red oak 5/4 rough through the DW735 and it tripped the breaker a few times as well anytime I tried to go much beyond 1/16-1/32” (that’s a small range in my opinion).
Your extension cord seems to be well within spec like you said, but does your outlet allow for enough amps? Once I changed outlets on mine to a higher amp’d one, the problem seemed to go away for me.
Also, how sharp are the knives? Dull knives tend to drag the motor a lot.
Are both ends of the board well-supported?
Personally, I’d get a bandsaw if I were you and slice it down closer to 3/4”. You seem to be wasting a lot of wood just planing it down. And, in doing so, you’re probably wasting a lot of time too. Just a thought.
