Sure, I’ve got a stash of junk from the workshop floor—an old blender, a coffee maker, even a broken vacuum motor. I can hand them over, but keep safety in mind; make sure you have a proper test rig and a pressure release in case the little engine goes off the rails. If you can mount it on a lightweight frame, we might get a decent thrust curve and I’ll help tweak the airfoil to keep it efficient. Just give me a call and we’ll sort out the details.
