Steamer

I'm using Wedico pumps on this one and they're designed to run both ways forward and reverse. My problem is when the cylinders are full stroke the pumps pull all the oil out and create a vacuum. You can imagine what happens then, the box slams all the way to the bottom because there's no oil cushion left in the cylinders. I thinking with the internal springs there should be enough return pressure to start the box down when the pump reverses. At least that's what I'm hoping for.
