Why get the 3 HP? It’s a little like buying a pickup with the big V8 for those times you pull your RV over the mountains. Because you will occasionally turn big wood with this lathe, you will appreciate the extra power. It’s also much cheaper to order this option with the lathe, as you are just paying the incremental cost between the 2HP and 3HP. If you order the 2HP and later want to change, both the motor and drive need to be replaced, and the retail value of these two items combined is greater than $1,000.
