Hi, Knot Rite:
The lathe has three speed ranges that require moving the belt to different pulley combinations. I was quite surprised at how much difference there is in available torque between the ranges, considering that the difference in radius of the pulleys is only about 1/2". In this video I was operating in the high speed range so therefore the lowest torque range. It quite likely did slow momentarily as I started a heavy cut but I think it just took a moment for the feedback circuitry to "catch up" and increase the power to the motor. I can't say the slowing was noticeable while I was actually turning.
I am really surprised by how much noise is added when the tailstock and live center are used. When turning a piece mounted only in a chuck the lathe is very quiet. Using the tailstock and live center really increased the noise level. I wear hearing protection while I am in my shop so I really didn't notice the difference until I was reviewing the video.
Here is another video using the new lathe:
