So what was the elapsed time to change out the cutter head
and be up and running? Any alignment problems?

No problems other than those mentioned. It just took a couple of hours, but
working at a tool store, I had everything around me I could possibly need.

These new cutter heads seem like the answer to a prayer
when it comes to planing highly figured wood. The sample
board you show was a great test - high figure AND knots -
both "challenging" for conventional straight knife knives.

I cannot wait to take it home (raining for the last few days) and try it on
some of the squirly ash I have.

Thanks,

David.
