Surprisingly enough the HVT-2 is pretty low, im only 5'9" and I still have to hunker down a bit to comfortably turn the carriage wheel. Im putting some leveling castors under it, as space is limited in my garage and i need to be able to move it from time to time without the engine hoist, but im also putting some 2x3 tubing under it as well. to lift it some more. What are your thoughts on where the wheels should go under the headstock? I've got 4 castors, should I put 2 castors and 2 manual feet under the headstock or just let it fly and center the castors under the headstock?
