3Hp hydraulic power unit

[Frank S]

Actually this would fall under the sub forum tools in progress but I think that one is gone.
After building my plate roller rather than press it straight into service I decided that I wanted to power it hydraulically.
This meant that I either had to dig through 10 tons of stuff still stashed away in 1 of my storage trailers to try and find where I had put my power unit or build another.
To build another was the easier choice First I started with an old automotive lift power unit off of a larger lift actually it was one I had removed from an elevator I built 20 years ago when the coupling went bad a few years back.
I made a new pump to motor coupling "see Pump/ motor shaft coupling
Then I inspected several pumps that I had and checked the motor, then located a 4 way valve the one I decided to use is a 3 bank valve I will cap 2 of the sections for now but may need them when I use this power unit to test other equipment.
next was to decide on a tank the 6 gallon plastic tank didn't fit my design criteria, so I settled on a 15 gallon steel drum it has a good diameter to height ratio being almost the same in height as in diameter.
I couldn't just mount the pump and motor directly to the top as the metal was too thin for my liking so I cut 3 old truck mud flaps to fill the depression in the top Then I needed to cut a round plate to cover these with and bolt through everything.
this was why I made the Simple plasma torch circle guide to cut out the round piece
here are some assembly pictures I still need to make up 3 hoses tomorrow if I have the correct fittings then will have to wait until I need to make a trip to town to get the oil.
