rick,
Scrounging through the archives I found a post by you when you picked up a marvel no 18, (https://www.practicalmachinist.com/forum/threads/marvel-no-18-universal-power-hacksaw.95953/). I was especially curious about the hydraulic diagrams you mentioned, we have the same machine and need as much info prior to a upcoming refresh on a very deserving machine.
