RE: How to add downthrust on a backplate mounted engine?
Why, that's the Binford 5000XL, Arr, Arr, Arr, as 'Tim the Toolman Taylor' would say! It's a Craftsman 12" with reversible jaw(spreader), actually. I've got a bunch of ancient cast Bessey bar clamps, they're fine for general carpentry, but no matter what I put under the stupid little round foot, they walk when I'm doing finicky little stuff like this.
