I have an early 1900's Cincinnati planer in fairly good condition I'm thinking about converting to hydraulic operation. It was originally built as a line shaft machine so I need some other way to run it.
One option is to use the existing drive system only to power it with an electric motor and a gear box.
Another is to build a hydraulic power pack to run the drive system.
A third option is to attach a very long (9ft stroke) hydraulic cylinder to reciprocate the table of course with the various accompanying controls.
I like the third option best as I could eliminate the gear & gear rack which drives the table. I plan to use it as a big honkin surface grinder to resurface lathe beds, etc and eliminating the gear & rack should improve the surface finish.
So any ideas as to where I could find a 9ft stroke hydraulic cylinder without taking out a second mortgage? I still need to calculate the forces needed, but just off the top of my head a 2" bore would probably be enough. The table, if completely solid, would weigh in right at 2000 lbs, or 900 KG. Since it has various slots, holes, etc cast into the table I'm making a SWAG that it's around 1500 lbs, or approx 700 KG, possibly even less.
I'd like to find some place that offers reman cylinders for sale. An internet search turned up plenty of shops that will rebuild your own cylinder, but none offering reman cylinders for sale without a core.
So anyone have some ideas?
Thanks,
Stan
