The tooling should not change anything if done right. Providing the tooling has the same width on the cut.

Main problem with slit saws is any little vibration or imbalance will make the channels wider than the width of the blade. Thay can become out of balance a lot easier than end mills especially if ran hot. Probably not the case here though. That much of a change was probably some other issue. Still shouldn't change the results that much though.

I don't see it taking 30 minutes to mill a white water with a end mill. The channels are not that deep. 2 passes at 1IPM would only be about 20 minutes. A good mill should be able to run at least 5IPM conservatively with a 1mm end mill in Copper.

It would be about 16" total (just the channels) with 2 passes. 32" with 4 passes. Should be under 10 minutes on a good mill. Slit saw would probably cut that in half as you should be able to make the entire channel in one pass. Anyway Bruce or Cathar can correct me if I am way off as they both done it each way.
