Seeking Spring Nuts for Series 1 cabinet

Dave Wise All Messages By This Member #105336 开云体育 The top and bottom covers of the 740B are secured by screws which go through 6-32 J-style?spring nuts clipped onto the side panels. ?Except I'm missing some of them. ?The manual doesn't mention them. These particular?spring nuts (speed?nuts, clip nuts, Tinnerman nuts, J-nuts, U-nuts)?seem to be obsolete or custom-made; I can't find anything to match. The sticking point is the?1/8-inch panel depth. All I can find?are for a 1/16-inch?panel. Got any leads? Thanks, Dave Wise PS: I think U-style would work as well as J-style.

I too would like to find a source for spares, so I'm following this as well. -Pat toggle quoted message Show quoted text On April 21, 2020 at 12:15 PM ken chalfant <kpchalfant@...> wrote: Greetings, How about McMaster Carr or Fastenal?

Dave Wise All Messages By This Member #105346 开云体育 ??No joy there either. ?McMaster does have one "clip-on nut" for number 6 sheet metal screw and 1/8-inch panel but the throat depth (from bend to hole) is about twice the 3/16-inch I require. ?Fastenal has one "U-type spring nut" but it's?0.040-inch panel and everything else is thousand-dollar minimum?quantity. ?It was the same frustrating story everywhere I looked. ?Either no info, didn't meet spec, or out-of-reach price. Jeff Kruth comes to the rescue up-thread with a personal stash. ?Thanks, Jeff!

Now I'm confused. ?If I'm Series 2 (cast Al sides), then what was Series 1? ?Is there a cheat sheet, or representative example models?

Robert G8RPI All Messages By This Member #105351 HP never called the original modular cases System I but did call the later one System II Original (System I) had one piece cast alloy side panel frames with continious exposed edge and vinyl coated flat alloy side panel inserts. Front and rear panels were folded flat alloy sheet lacated in slots in the side frame and clamped between them. System II had one piece cast alloy front and rear panel frames, connected by either two internal side castings (generally on small cases) or 4 corner casting on larger ones. Front an rear panels alloy and held in frame by hidden screws. See the 1976 catalogue for pictuers of both. Robert G8RPI.
Robert G8RPI All Messages By This Member #105353 Forgot to say, 740B is Original "series I"
Dave Wise All Messages By This Member #105359 开云体育 Sorry for being dense, Robert, but could you name a specific model from the catalog as an example of System 2. What cabinet?is the 339A Distortion Measuring Set?

Jeff Kruth All Messages By This Member #105360 OK, fair enough. But what were the "other" cases from the dawn of time. series "0"??

Robert G8RPI All Messages By This Member #105366 The 339A is a System II case. Quick test: Put your finger on the bezel edge on the left side of the case and trace the unbroken line of the bezel upward to the top LH corner, If it flows back with a radius to the top of the side of the case it's original modular (System I), if it turns? 90 degrees right with a sharp corner and across the top of the front panel it's System II.

Robert G8RPI All Messages By This Member #105368 Hi Jeff, I tried not to correct you :-), the System II does have cast side rails, but they are hidden under the panels. All this applies to the MODULAR case system. The early instruments and some later ones were not modular. A good example the the 5315A? and 5315B counter The 5315A (and 5314A) are not in modular case but the 5315B (and 5316A) are in System II cases. Modular cases can be racked and stacked with two or 3 small insruments of the same height filling a 19" rack.? Some of the bigger orginal instruments had handles built into the sides but are still of the same construction. HP sold the cases to end users and other OEMs to build their own insruments into so everthing matched. Robert G8RPI.
