I'm sure most of you DEC hackers have replaced a broken DEC handle or put
handles on a protoboard... I finally came across the right tool for the job, an
Indestro tubular rivet set!
When I worked for a place that made Unibus and Qbus boards, we bought
bulk metal quad and hex handle assemblies from DEC, no number stamped
on them. We used a floor-stand foot-powered Stimpson rivet setter
with a lower die that held the rivet and an upper die that set it. I
saved the Stimpson machine when the company closed.
It's one of these:

quick work of setting rivets but overkill for hobby use. We shipped
over 1200 Unibus and Qbus boards, so we set well over 10,000 rivets on
it. I probably did at least 1,000.
they're 1/8" hollow brass rivets, but that a M3 x 5mm is close enough. You can
buy the M3 rivets online for cheap, I paid $6 USD for 200 rivets, shipped.
Good to know. I still have a bag of our old stock, but if I run out...

Stu Phillips, a friend of ours did the insertion of metal metal Southco
extractor handles on our boards for the Microdata 1600. He probably had
a machine, as the Southco levers were riveted onto our board thru holes
in the corner and levered the board in and out of the card cage.
He made a line of the ears for the DEC manufacturers here in Orange
County, and I've seen his SPC or Stu Phillips or Phillips company logo
on may such products.
That business came from him owning an injection molding machine and
someone asking him to make the handles. His original business was doing
jobs like the riviting and other assembly jobs around Orange county.
thanks
