Chris, I do not know why you need the variable speed with that lathe. Maybe my memory is failing me, but I recall either that lathe having 18 or 24 different spindle speeds. I have a late model 18 x 54 Lodge & Shipley with a
15 HP motor and it has 24 speeds. If you still want to change, 10 HP is more than enough. I have a HP meter on my headstock and I have never used more than 5 HP even for the biggest cuts. Steve- Vote on answer

A Monarch of that vintage would have 16 spindle speeds, hardly warrants a vfd. The best bang for a buck would be a bigger motor pulley & belts to speed up the spindle. The optional bigger hp Monarchs were usually slower than the standard models.
10 hp was standard for the 20 inch of that vintage.Tom
