You just can't help yourself can you? Showing off how big your head is....
How do the blades on the last one adjust, or don't they?
Do the top and bottom knives both cut at the same time? Is there overlap on them?
The blades are not adjustable. Yes both top and bottom cut at the same time. They overlap in the center of the head. It should make a decent setup for cutting square edge tenons up to 2.5-2.75" long. Or as a single head running stock material to a specific width.
This was for another forum, but my 3.25hp pc router in the lift next to these heads. They are a bit ridiculous, but were cheaper than my favorite router bit.

Wait till you see the shaft...lol
Just here showing off the shaft. It needs bit more girth and length for those heads in reality.
