Hey all, Just saw this on e-bay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=13718&item=6177892220&rd=1&ssPageName=WDVW He says new not old stock. He says correct hole diam. He got em' somewhere. |

Ah, yes. "Lord mounts" we used to call them. I don't know why I didn't think of these. Used to see these all the time in military aircraft. Avionics racks are mounted to them a lot of times. Some of them were fairly "loose", as I remember, but others were very stiff. Might check a military surplus for these, especially any that sell old avionics. DRMO would probably be your best bet. As to the Ms Pac grommet on ebay- I wonder if the guy finds a stock mount then drills the center hole out to the correct diameter? |

Meaning, at least I think, is that these things were never meant to have force applied in the manner of a joystick. That is why I think that someone somewhere went "Hey that'll work". --- End quote --- They also usually have a radial load spec, for side to side movement. But yes, the twisting action is probably way outside of what was expected for these when they were designed. --- Quote ---He says new not old stock. He says correct hole diam.

Maybe that is what this one is and if so, I have 10 of them on my shelf. If drilling these works out, I'll stock a few of these and put them on the store. They'll be cheaper than this guy on eBay, that's for sure. BTW, if anyone has a set of calipers and a WICO shaft, please measure it and post the dimensions. I'd like to get a feel for the tolerances on these when they made them. Mine was .006" under the 3/8" nominal. Is anyone else's over nominal? Thanks, RandyT |

I dunno about that auction... It lists Galaga, but from what I remember of my Galaga joy, it has NO grommet. It springs back into place due to two metal "leafs"... |
