Van Norman Mill
Hello, my 1st thread here.
I recently bought a Van Norman 24MLA. It uses the round bar overarm. I don't believe the overarm has ever been used & the overarm supports lend to the idea. Is there some special way of unlocking the overarm from it's fully retracted position? I have removed both binders & soaked the arm with WD40. I am prepared to hook up a 10 ton portapower to make it move - but do not want to damage anything. The manual takes for granted I know more than I do. The blow up drawings simply show a round rod installed with 2 binders & nothing else to hinder it's movement. All input welcome (except the politics WOW). b |

Less likely is its jammed into place. Remove the 2 " locks" and spray the snot out of everything with either Kroil or P'Blaster and let it sit for a day or so. If it still wont move, take a 4x4 and have someone hold it on the ass end of the overarm and smack the 4x4 with a sledgehammer. Now...does this one have a rack that pulls and pushes the overarm? Some do. Make sure one of those "locks" is not a lock, but a lever to turn the gear on the rack. I had a Van Norman #36 for a couple years, but its a flat dovetail machine (with 1 lock and 1 crank) https://goo.gl/photos/7LBcBhvfD1MVWB5n8 Gunner --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

I got it freed up! There is a threaded bore in the front with an Allen head plug. This front threaded bore is the same size as the end of 1 of the drawbars (2 were included in my purchase). Also, 2 overarm bars with spacers came with it. So, after much soaking with PB-Blaster, I fashioned a slide hammer out of the above parts & now the overarm moves freely!!!!!!!!!!!!!! |

You will LOVE that machine once you get the hang of using it. They truely are brutes and are very hard to wear out enough to hurt the accuracy of the cut. Slower to use in todays "high speed" world..but they are absolutely the tits for heavy work or home shop machinists. |
