Hello everyone, this is my first post here so bear with me please. This is also my first project of this magnitude as well. I am basically taking an old lazy boy chair, it's a two seater putting it on a frame and using two go kart engines with torque converters on both of the back wheels to provide power and steering, each engine will be completely independent of one another. And the budget is hopefully low. My first dilemma is what front wheels to use, I thought about using heavy duty casters, like the ones on shopping carts. Thoughts on that would be much appreciated. My second dilemma is how to make up an axle assembly for the rear, I have no ideas here so anything would be appreciated at this point. Third, is how problematic will running two engines separate systems be, I assume there will be some type of problem here. Thanks in advance.
