Ink Bearers

I'm not altogether happy with this setup but it got me through the job. I followed the instructions over on the Poco website for using a brass bar snugged into a slot on one side of my boxcar base. Unfortunately, the roller I have, which cost quite a lot, wouldn't span all the way to the other side of the base so I used double stick tape and combined two leading strips and just laid them on the boxcar base alongside of the polymer plate. I had trouble with the strip sticking to the tacky roller and lifting up so I devised a little masking tape sleeve into which the end of the strip would slip which reduced but didn't completely eliminate the problem. I stuck a shorter piece of masking tape face to face with a longer piece so I had a non sticky tunnel with sticky ends to tape it in place

My first inking strip was shorter and hard to handle since the whole thing would get inky. I made a second longer strip that hangs off the end of the base resulting in a clean "handle" for removing the strip before running the press. By the end of the printing session, the leading had a slight bend at the point where the boxcar base ends so that may become a problem. I'm thinking of trying to cast a wide roller myself.

Here's my apprentice (aka husband) taking the print out of the registration guides. If you look closely you might see the clear mylar "frisket" drooping below his left hand.

I saw a recipe for composition roller material in a post on Briar Press and tried it out. I made a lovely flat plate (for monoprinting), so now, once I get over the memory of the smell, I hope to try to make a roller. Just haven't figured out how to do the handle. One idea was to use an old ball bearing wooden roller and cast around that. (Lynn Starun)

Determined to get the Most from my Poco!

Hi Group,

I've had my Poco about two years. It took a while to sort out some missing bits (the stops) and get it working smoothly. Boy, it sure does love some lubrication on those gears. I wonder what product everyone likes best for that? My husband thinks I should switch from generic grease to his teflon bicycle chain lubricant.

I got a metal plate the thickness of a galley and the full size of the bed so it's now type high. I'm using Yupo as my tympan--it's durable and wipes clean. So far I've printed some book arts kinds of things with metal type and linoleum blocks and that worked pretty well but I realized registration was a big issue. A friend has a proof press and thinks I should just register on the cylinder but my experiments didn't seem to work. Since it prints from both directions I couldn't just rig up a registration device like a Vandercook would have.

I liked Neil Giroux's idea but didn't have the metal working skills to make that and didn't like the business of hanging it from the ceiling. I'm in a warehouse with a VERY high ceiling and I'm 4'11". After some thought, and looking at any other tympan/friskets I could find, I decided it would be good to have it open across the bed. Hinges need to be small and I thought of those piano hinges I saw at Home Depot. I do some bookmaking and have lots of binder board so I attached a piece to the piano hinge which can then be locked up in with the furniture. One minor drawback is that the piano hinge is a little too short but I can hold it at the right height for the hinge and if I tighten the quoins it will stay at the right height. There are two sizes of piano hinge and I used the narrower one. I make the holes with a Japanese hole punch.

The first prototype was without a frisket. I just cut a hole in the binder board where the type or image was and made registration stops on top of the binder board. I'm printing a wedding invitation right now using a boxcar base and polymer and realized the binder board alone wouldn't be a good idea. So I used some heavy mylar as an underlayer and added it to the hinge instead of making another hinge. It worked but it was a little awkward to use-kind of like opening a two page book. I cut out the print areas from the mylar and put register stops on the binder board.

I'm wondering if I can find a better material than the binder board because it's a little too thick. I like the piano hinge because it is very reliable in that is doesn't shift or wiggle. I use very short flat bolts/nuts. They are sold in the hardware store with a sort of matching sleeve and are what you might use on a photo album and I think it was called a "post". It has a very low profile head and I replaced the sleeve part with the thinnest nut I could find.

One thought I've had would be to use a some kind of sheet metal for the tympan frame/frisket frame with the center cut out so that it would not need corner hardware. I actually wondered if a hinge of duct tape would work. I really like those carbon fiber hinges I saw on the blog. Will the epoxy be strong enough to hold the frame together?

I should mention that my poco was sandblasted by the previous owner and used as a display piece.

Well, that quite enough for one post. I posted on Briar Press (Poco stops and other issues) and if you scroll down there are some more photos.
