Default Busch Pressman - how to lube rotating back?

I picked up a pretty nice Pressman D for small money a while
ago. The back rotates but is very, very stiff. I don't think
this is normal as one shouldn't need three hands to turn it;
in its present state the rotating back feature is not terribly
useful.

It would seem some lubrication is in order, but here's my
problem. It's totally unobvious how the mechanism actually
works since all the surfaces I can see during rotation are
basically flat. I tried a very light film of moly grease which
didn't seem to help. I assume there's something inside that
really does the work, and is where the lube should go.

If I rotate the back to 45 degrees I gain access to four
screws in the corners, which I guess hold things together,
but I'm nervous about disassembling it in case it's massively
spring-loaded - the last thing I want/need is bits and pieces
flying all over.

So far I haven't found any disassembly pictures or info on
the web. Has anyone ever operated on one of these and
documented the process? Better yet, does someone have
access to a factory assembly or service manual?

First, remove it and clean the bearing surfaces.

DO NOT USE graphite lube because it has a tendency to invade everything
to make your life miserable!

If you do not come back here, then you are not participating.

Take your unit apart. Clean it with a toothbrush and mild abrasive such
as baking soda.

Then come on back.

The removal method was the essence of my question.

Excellent point, thanks for the reminder.

I didn't say I wouldn't come back, but in my Usenet experience
since the early 1990s, some people prefer to reply privately, or
to send email in addition to posting. An email sent is not an email
received, ditto for Usenet posts. Redundancy improves reliability.

Some kerosene on a cotton bud can work for stubborn dry old grease. Wipe off
and lube with a mere wipe of Vaseline. Again a cotton bud can prove good.
You will be surprised just how freer the movements will become with this
treatment.

Don't bee too afraid of disassembly. These old machines are pretty basic and
straight forward in their design. Just be careful that screw drivers fit
neatly in the slot to avoid slipping and butchery. Those small sets of
?jewelers? (or pretend jewelers) driver sets can prove valuable. And finally
there is no need to screw the hell out of these fine screws upon reassembly.

It was a snowy afternoon and I had nothing planned, so I went at it.

I filed the designated sacrificial screwdriver until it was a good
fit into the retaining screws. They came out easily and the back
lifted right out. The bearing surfaces were cruddy with dried
lubricant, which I cleaned up and replaced with new moly grease.
What a difference!

Thanks all for the encouragement.

It's always good to learn of a success. Congratulations!

It is zero Fahrenheit here right now. Got the walk shoveled, and now I'm
staring at a Deardorff 8x10 that needs a leather handle. I can make one.
But the two metal retaining strips are missing. I do not have a metal
bender (brake). And I can't find any split rivets.

Any ideas?

I'll save my unhappy comments about the Deardorff V8 for later.

Two suggestions -

If there is a Tandy's leather shop close by, pay them a visit and see what
they can do for you.

Or visit a shoe/leather repair shop. Perhaps they can figure out something.

Aren't those just the thin sheet metal strips that run the length of the
handle? Should be able to cut those out of thin sheet with a pair of
tinsnips, I'd think. Unless you're talking about something else. (I've
repaired handles that way using tin cans before.)

Nope.
