That HF lathe has a 3/4 HP motor, are you saying that it isn't enough?
That's exactly what I'm saying; 3/4HP is not enough if you want to turn a bowl approaching the 12" maximum. It'll maybe suffice for a platter, but it bogs down on a 10" diameter x 6" deep blank of green maple.
Oh, I also forgot, reason (c) the slowest speed is not slow enough if you want to turn big blanks that are off-balance.
Also, can you explain more about what a "Reeve's Drive" is and what is not good about it?
A Reeve's Drive is a mechanical speed adjuster that works using two inter-locking conical wheels. When you move the handle, the cones move on the common shaft, effectively changing the diameter of the pulley wheel the drive belt encircles.
You can only change speed when the motor is running (unlike a variable speed motor). To me, that's the biggest drawback -- if I forget to lower the speed before mounting a big bowl blank, I have to remove the blank so I can power it up safely and slow it down.
I'm NOT saying "don't buy the HF version for $200" -- I'm saying "don't pay $800 for the Jet version, for that much money you should get a much better lathe".
