Hi all!
I have a few more thoughts on calibration, trucks, etc:
* I respectfully disagree with the assertion that adjusting roller height
is a "fine" calibration issue. When I tried to print with a plate, the
rollers were inking the base. The plate itself is 1.52mm thick. Type height
is .918 inches, or 23.32mm. That's at least a 7% difference from nominal.
No engineer I've ever worked with would consider a 7% or more adjustment to
be anything but a very coarse calibration.
I also have to wonder how much damage has been done to our rollers over
the years by the excess force of them being pressed into the type much
deeper than is necessary to produce even a shoddy impression.
I've been trained/qualified at Boston Paper Collection, and have a
qualifying run scheduled at AS220, the operators at both consider
adjusting roller height to be a very basic step in the makeready, along
with adjusting the bedding on the platen, and alignment and registration.
It doesn't take long and is very conceptually easy. Of course it is not
required for every job, just as careful centering of the print on the
cardstock, or making sure the print is square to the edges of the cardstock
is not strictly speaking required for operator or equipment safety.
* I did some reading on Morgan/Delrin trucks and called a friend of mine
who has a printshop in Seattle to discuss it. After studying the question I
really cannot recommend the Morgan trucks for a couple of reasons
* Even unused New Old Stock trucks can have hardened rubber. This
means functionally they are not any different from steel trucks, except
that they are more brittle.
* The rails are worn unevenly. Adjustable trucks will raise the
rollers to compensate for average height but cannot compensate for divots
in the rail itself.
* They are very fiddly and hard to adjust. All of the tools and
maintenance I have done or would like to do has been with the goal of
making it easier and less frustrating, for everyone not just me, to do the
makeready, not harder.
* That said, every operator should make their own decisions about
things not related to safety. Morgan trucks, or their competitor Delrin's
trucks, will in fact raise the rollers, as Len said. Whatever method you
choose of raising the rollers will alleviate problems with letters filling
in, will prevent ink from getting on the chase and furniture, will allow
you to go longer before needing to re-ink the plate since ink isn't getting
wasted on the chase and furniture, and will make it easier to clean the
type as there won't be ink on the shoulders of the letterforms. Whatever
tool you use, this is all goodness, for the equipment and cleanup time/your
sanity!
* If you want to try the Morgan trucks and Len isn't around to show
you how, I found a scan of the original user instructions here:
https://www.flickr.com/photos/thearm/335361179/in/photostream/ A bit hard
to read on the screen but perfectly legible if you download them and print
them out. Good luck!
* Of course hard tape is superior to masking tape, which will deform under
compression, and will also get brittle as it ages, but UMHW tape is
$1.55/foot from NA Graphics. Other suppliers have it for $6/12yard roll,
with a minimum order of 12 rolls. I just do not have that kind of money for
tape when masking tape is a cheap and reasonable substitute, especially, as
Len pointed out, given the other ways in which the press is worn
(well-loved I say!) and no longer printing in like-new condition. Again as
Len pointed out, 99% of the users of the press do not need accuracy down to
the micron, which is what the difference between masking tape and hard tape
will get you.
* A note on that durable and re-usable equipment: the equipment I've bought
should be considered on loan to the APOster shop. It has always been my
intention to purchase a press and set it up at the artist co-op I know of,
largely so that I can train friends of mine who are not APO brothers, but
also so that I can ethically charge money for the items I print. I have
purchased close to a thousand dollars worth of durable equipment that I am
happy to let the fraternity use in exchange/barter for the amount of space
it takes up in the shop. Molly, other actives, if this does not sound
reasonable to you, please let me know immediately so we can work out a
rental payment agreement or so I can remove the type and tools immediately.
To be clear the equipment I am talking about is one and a half typecases of
type, an aluminum block 8" by 12" and 21mm thick, and a roller gauge, .918"
in diameter at its widest point about about a foot and a half long.
* A little note, but an important one, I am not an "alumnus" of anything, I
am an alumna. Latin, like it's descendant languages, has gendered nouns. An
alumnus is a male graduate of a school, college, or university. Alumna is
the feminine form. The male plural form, alumni, is used to described a
mixed-gender collection of graduates, but an all-women gathering should be
referred to as alumnae. I personally use any of the English language
synonyms such as alum, graduate, or even cruft to avoid the risk of
accidentally assigning the wrong gender to someone. This is also more
welcoming and compassionate to our transgender brothers.
* I would be very grateful for the names and contact information of
specific shops that allow outside press operators. I know of Boston Paper
Collective (very expensive and also does not have a clamshell style press)
and AS220 (in Rhode Island and therefore outside of what I would consider
"the boston area"). I also know of the letpress mailing list and the
briarpress forums, where I've found the names of a number of shops. I've
emailed or called about twenty shops in the past year and a half and all of
them have told me the same thing: they are private studios and only the
owners and fulltime employees are allowed to use the equipment. If there
are truly publicly accessible shops, I haven't been able to find them, in
spite of a great deal of effort looking, and again, I would be very
grateful for specific names and phone numbers, not a generic and unsourced
assertion that they exist.
* I re-iterate, if the actives and my fellow journeyman feel it is
inappropriate for me to continue using the shop, I will remove my projects
and belonging immediately. I will take silence as assent to continue
printing and offering to train new brothers.

=C2=A0 =C2=A0Hi pressops!<br>
<br>
=C2=A0 =C2=A0As I mentioned earlier this summer, I purchased a* base for pr=

=C2=A0 =C2=A0with plates*, from Boxcar Press. It now lives on top of the bo=

=C2=A0 =C2=A0I'm *planning to adjust the platen* either this weekend or=

=C2=A0 =C2=A0since even with the roller height calibration described below,=

=C2=A0 =C2=A0schedules.<br>
<br>
=C2=A0 =C2=A0I also discovered, printing my first plate, that the rollers a=
re very<br>
=C2=A0 =C2=A0dramatically set at the wrong height. There's a couple of =
reasons for<br>
=C2=A0 =C2=A0rollers to be too low: rubber shrinks over time, and the truck=
s and<br>
=C2=A0 =C2=A0rails wear. (Rollers can also be too high if you have the wron=
