    I like it- and I understand what it does, but I don't recognize all those parts. Do you mind explaining a touch further? "Pump the handle on the hydraulic, and that turns the [fill in blank] which causes the [fill in blank] to expand.

    What's the max wall thickness it will expand?

    I used the harbor freight hydraulic punch set and theor exhaust expander then machined an arbor to adapt the hydraulic part to the expander

    Not sure on Wall thickness I will have to do some testing
