Author Topic: How do I get my long shaft out of this hole? Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 09-01-2008 07:35 PM                        I have a Neumade PRT Ultra work bench which was designed in The Land Without Common Sense back in the 1400's or so. I have a spindle where the key for common shipping reels has long since worn off. See? I need to get the shaft out and replace it with this new one I found: But there doesn't seem to be any screws that allow this. There are only these weird, tiny holes with what appears to be some sort of pegs or things in them: One goes through the shaft to the other side, and the other simply locks down and provides pressure on the outside of the shaft. They aren't screws. How do I loosen them and/or get them out, and then how do I get them back in once the shaft is replaced? I imagine I'll probably have to travel back in time to before color was invented to procure the proper tool. Maybe one of the tools is a hammer?  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

Does the new one have the hole in it for when you want to put it back in? This could take a while. Is the old shaft badly bent or is it just missing the key? It may be more trouble than it's worth.  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 09-01-2008 07:47 PM                        I think they're called expansion pins. The one that goes all the way through, you can punch out with something of the same diameter, at least far enough that you can get some pliers around it. The other one, you'll probably have to drill out. Hopefully, the pin is softer than the metal around it. You can buy replacements at Home Depot, & some hardware stores with decent fastener sections.  |  IP: Logged Jon P.

If you don't know where to get them (doing a quick Google search didn't come up with any info) I can ask our tech where he gets 'em, we have the same type of icky workbench and, before I found the shaft with the adjustable pin that fitted both the shipping reels and our 6k reels, we used to chew up those puny keys.  |  IP: Logged Jeremy Weigel Phenomenal Film Handler Posts: 1062 From: Edmond, OK, USA Registered: Mar 2007 posted 09-01-2008 08:02 PM                     They're roll pins. You can either tap them out with an object slightly less in diameter or drill them out (which I usually do when they're that small). You can buy replacements at just about any hardware store.  |  IP: Logged Robert Minichino Master Film Handler Posts: 350 From: Haskell, NJ, USA Registered: Dec 2005 posted 09-01-2008 08:11 PM                        Those pins are called spring pins, roll pins or split pins (the latter also refers to cotter pins), they're friction fit into the holes (they're springy so they stay in) and they're driven out with a pin punch and a mallet (or hammer ).  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-01-2008 08:48 PM                     (OR, you could take out the key from the new one and put it in the old one ....be a bit easier... ) .. and find a supplier that still has those keys in stock for the PRT ULTRA... Or, if you want to do it the hard way, get a good bench vise and a drill bit as a punch to press those spring pins out. -Monte [ 09-01-2008, 11:59 PM: Message edited by: Monte L Fullmer ]  |  IP: Logged Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 09-01-2008 08:48 PM                     Joe I've got the same bench here at the house and got tired of breaking the pins so I now use the adjustable drive pin spindle. It fits cores, and all house reels and won't break. Throw that crap in the trash.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 09-01-2008 09:11 PM                        Push out the one that goes all the way through. Using a vice, twist off the shaft, which will shear off the short pin. Then push the short pin inward, shear it off with a punch, repeat until it is gone. Reassemble.

My experience with roll pins is on foosball tables where they're used to fasten the plastic "players" to the steel rods. The pins eventually shear off. Best way I found to get them out is pin punch (of the proper size) and a hard mallet or a hammer.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 09-01-2008 09:31 PM                        I need to have the key for my expandable trailer flange. The key on the new one does not look like it can be removed, and the old one has a worn space that does not look like it can be replaced. If you put something in there, it would just fall out via gravity. Yes, the new shaft has a hole in it for the pin to go through. I don't understand why something like this even exists. The Kelmar table doesn't have spindles where keys break all the time. Who thought designing it this way would be a good idea?  |  IP: Logged John Walsh Film God Posts: 2490 From: Connecticut, USA, Earth, Milky Way Registered: Oct 1999 posted 09-01-2008 09:32 PM                     Wow, a spindle from the 1400's! Must be pretty good to last longer then some glaciers! Those keys do break, but it is often because of, er, uhm, rough use; using 6000ft reels with the 5/16 spindle, turning on the rewind table with the speed control on full, etc. Replace the spindle like everyone said. The pin is a 5/32 spring pin. The key is pressed in; don't just try to put a new key in 'cause it will only fall out. Replace the entire A-1597 shaft.  |  IP: Logged Jon P.

I've done it and it will stay if you press it hard enough. Otherwise you'll have to drive out the roll pin and replace the whole shaft.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-02-2008 12:05 AM                     quote: Phil Ranucci I've done it and it will stay if you press it hard enough.. I used to do the same thing with a vise. But, did an additional trick was to drill the opposite end of the shaft with a large bit to create a countersink to when I pressed in that key, the tab would be exposed enough to where I would flare that end of the tab in that countersink that I created. That key didn't go anywhere...and I had a good dozen of those R-9 keys on hand.  |  IP: Logged
