Need help with strange inverted-hex-nut fastener
Need help getting off this strange "inverted-hex-hut" fastener:
How do I get this late 1960's portable suitcase-type record player amplifier out of the case chassis? It seems really dumb that I've already put in serious time and re-built the record changer which now works smoothly, and seems like only problem with the amp is 60-cycle hum from bad filter caps, but am getting stuck by the fasteners holding the amp in the case... It is held in by two strange fasteners "inverted nuts" which I've never seen - the late 60's - early 70's seemed to be "the era of bizarre non-standard fasteners". this is a family friend's childhood record player, so I really want to get it fixed even though it's not really collectable: Pictures: http://home.nc.rr.com/goodmusic/001.jpg http://home.nc.rr.com/goodmusic/002.jpg http://home.nc.rr.com/goodmusic/003.jpg It seems I need a "reverse hex socket"; alsmost like a really large allen wrench that's hollow in the center to allow for the pot posts. But I don't know if there is such a thing, since I haven't noticed them at Lowe's or SEars, and don't know how much it would cost to buy such a specialty tool. Have you run into these connectors before? If so, how did you get them off? Are these in fact standard fasteners, that I might get tools for at Sears or Lowes? If not, what would be your first idea of how to get them off (that doesn't involve a hacksaw or carbide drill bit? I was thinking of trying to pry up two sides of the flat washer-shaped parts on the front of the case against the black speaker cloth, and then just grasping them with a wrench to twist them off; then when I fix the amp and put them back on, to try and flatten them back out again so I can push back on the tone & volume knobs. But that could get ugly or break stuff so I thought I'd see if anyone has other simpler ideas before I proceed. I usually don't work on these later 60's turntables, so would rather not shell out big $ for a specialty tool off the web, but if that's the only way... Thanks in advance, - Good Music |

Need help with strange inverted-hex-nut fastener
First idea......
Try a sturdy needle-nose pliers. Stick the tips in the corner of the "nuts" and pull apart ( open ) as you turn them. However- I've seen old sets similar to this where those nut plates have some hide glue holding them to the cloth. Or- take a cheap Taiwan nut-driver and form a hex on the outside with a grinder or belt sander. Wouldn't have to be a precise job. Those pots wouldn't turn from the inside ?........

Need help with strange inverted-hex-nut fastener
Thanks all for the ideas; I don't know why I didn't think of gripping it
from the inside with spread-out needle nose pliars, but that worked fine (no glue or rust on this set). Also thanks for the tip on the "tube spanner"; I never knew there was such a tool. Did a websearch and found a pic on an auto tools website; looks like just the thing, will pick one of those up if I find myself restoring more units from this era. Regards, - Good Music "Wayne Tiffany" wrote in message ... I kind of remember them from long ago. What I remember is using my fingers if they were loose enough, or if not, a pair of pliers. Either grip them around the outside, or come in from the side with needlenose pliers. You also might try the needlenoses, or a pair of snap ring pliers, and expand them outward inside the hex. You might be able to get enough force/friction to get them to turn. Let us know how it works for you. WT "Good Music" wrote in message ...

Need help with strange inverted-hex-nut fastener
You can try to use a needle nose pliers working pressure to the outward
direction, while turning the nuts. From what I remember back in the late 60's there were many types of radios that used these types of nuts. I used to use a tool for this type of nut format. -- Greetings, Jerry Greenberg GLG Technologies GLG ============================================== WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm Instruments http://www.zoom-one.com/glgtech.htm ============================================== "Good Music" wrote in message ...

use a standard hex nut, drill the threaded hole out to a diameter that will
fit over the pot shafts then you can use a standard deep well socket or combination wrench to turn it, hope this helps Boyd "Good Music" wrote in message ...

The telephone company used to use a tool that might help. Don't know
if they still do, but if you know a phone man you can ask. basicly a long thing of what was described below. I think I just brut forced it with a pair of long nose pliers that were fat enough not to slip around once inserted between the stem and the shell. I am not sure, but the proper way to mount it may be the other way around, giving you a nut and a washer combined.
