Sort of off topic, but sort of not.
My department is planning to have a roast of the former director and
because he was a big user of our former VAX systems, some people think
that mounting a disk platter would be a nice touch.
Anyone have have an extra RA81/RA82 disk platter for free/cheap?

What better way to roast him than to award him with an entire VAX? Heck,
they are cheap enough, sometimes even free.
That ought to get a few chuckles, especially if it's a 6000 or 8000
series with all the peripherals.

I've got one, but it's occupying a place of honor in my collection. The rest
are sitting in my RA-82, which I'm not about to take apart. These things are
hard to come by, as actually cracking open a RA series disk enclosure is
akin to opening an industrial refridgeration compressor, they just aren't
designed to come apart. My friend managed to open one by chocking a concrete
drill with a high speed cobalt aircraft auger bit and drilling out the
bolt/screw things that cement the clamshell shut.

The unit my friend had was similiar, but the screws around the periphary of
the clamshell holding everything down were square instead of torx (the
"slot" in the screw was square) We came up with an appropriate driver but
couldn't get the things to budge. Post-drilling it looked like there was
some kind of goo in the threads, and around the periphary of the case. I
think it was some kind of sealant. I don't know if all RA drives had it, but
it *really* didn't want to come out.

I've not actually taken an RA-series HDA apart,
but based on the R80 HDA
that's sitting here (waiting for me to restore the 11/730 system...) it
appears you can remove some clips and pull off the front cover and then
undo a lot of bolts (admittedly with male Torx-like heads) and then
separate the 2 halves of the HDA. Why isn't it as easy as this?

Sometimes that goo (various kinds) can be loosened by heating up the
screw with an soldering iron. Sometimes...
