another general principle is that=20
* the leads have to be slightly shorter than the set lines of type
to restate what other said:
* the fewer quads/spaces/thins in a line the better
* you want the widest possible quads and leads @ the outside

kk
it's locked up now
i hope you can keep it locked up
i wish you had left it locked up the best you could.
if you had, i might have been able to debug the problem(s) better=20
i suspect you weren't tightening enough
and/or
checking that all the quoins were tight @ the end
you really have to check all the quoins - when you tighten one, those
next to it can get relatively less tight
* i replaced some of the furniture (instinct ... would have been
better not to)
* i added two thin reglets on the three quoin side,=20
so those quoins didn't have to be opened so much
(might have been better not to)
* i added a copper thin to the third line from the bottom,
and a blue paper thin (i advise against using these (they change
width when they absorb solvent/ink)) to the second line from the
bottom, so the letters couldn't be pushed/squished out=20
i didn't have time to reset those two lines
* i suspect the use of several pieces of lead, instead of a single
long piece was part of the problem with this lockup
* you had an unneeded piece of furniture in the lower left corner of
the chase
please ask me to show you what was there, etc.
the principle is that everything in the chase has to feel the
pressure of one or more quoins

I added a 3rd quoin
removed all the coppers and checked each line against a standard
width... so there is now a minimum of coppers, and I am 90% sure all
lines are the same width.
I moved some furniture, tried to give it more support... no luck
Maybe I am tightening it too much?

thanks everyone,
Kristin
