I did see that improvement thread. Very nice work. If this press was a permanent thing I might do that. I need my jack to be easily converted back to upright use. I was able to use heat and a mandrel to expand a piece of plastic tubing for a press fit into the pump inlet hole. So far, it works being held upside down in a vise.

The press frame is not mine. I was able to borrow it from a friend. Now working on the spring return, the valve knob, and mounting it on the press with as little modification as possible to my friends press.

Will post a new thread when it is completed.

Thanks for your inspiration.
