[ARC5] ARC-5 Slide Snap Latch

[William Ripley]

Thanks for the information.  It is REALLY helpful.  If you have the PDF handy, it would help me a lot.  I am on travel for next 2 weeks in India, so not always sure when I will get good internet.

Though I never say never, no one I know of "makes them" any more, Bill.  The closest I could find was the MS21332 series "fastener - snapslide", with dash numbers for the piece parts of the assembly: -11 for the "latch", -23 for the "latch guide", -35 for the rivet, etc. Having an old spec (it was updated to a NASM21332) doesn't mean they're off the shelf, though.  I can send you the pdf for the assembly if you want it - it's only 500kB.

Whenever I have needed a few, I grabbed some from scrapped command set covers.  (Everyone saves these, right?)  They are slightly different from the MS21332 in that the end of the latch guide is also a rivet.  Drill out the retaining rivet for both the sliding (latch) and stationary (latch guide) portions of the assembly - the one with the .220"D head.  Discard this and fabricate a new one out of stainless steel.  That will leave you with the stationary portion of the slide still riveted in the hole for the post on the equipment.  Using a sharp end mill, carefully mill out about a third of the rivet - try to remove only the flared portion of this second rivet.  Use a .225"D pin to drive out the stationary portion remaining - I made a stepped pin to keep the drive pin centered.  The material is only .012" thick, so it's fragile.  Then restore the finish with nickel plating if necessary.  I don't bother with trying to rivet the stationary portion back in the new hole - the remaining rim seems to hold it well enough.  It's a bit of work to do all this, but if you are trying for originality, then I don't know of an alternative.

Good luck!

I am looking for someone that makes new miniature Slide Snap Latches, just like the ones that are used to secure the access covers on the command set radios.  All that I find now in the commercial marketplace are too big.  Any ideas?
