That depends on if you use a single, double, triple or quad lead worm. Each of these provides a different level of efficiency - roughly 60%, 70%, 80% and 90% respectively.
We have never used a worm/worm gear combination for a drive but we have used it at the elbow of an arm. We needed to maintain a high level of efficiency and went with a 4-lead worm. I would worry less about the efficiency and more about sheering teeth in a pushing match. You may find that the wheels slip before the teeth fail but it can happen. Trust me! We experienced it at IRI in 2005.
Great looking drive Cooney! I was impressed with the prototype video when I saw it a couple months ago. Very smooth!
