Bent Bumper on Uni I - Posted September 25, 2006

It’s finally time to fix the bent bumper on my Uni I.

The bumper bar itself has been bent from use, which makes the bumpers useless when the press is on short-trip (when in s-t the bumpers stick out from the press instead of hugging the sides of the press). Has anyone ever straightened the bumper bar? I’m not worried about disassembly/assembly, as I’ve taken that part of the press apart before when I was working on the adj. bed. But I’m worried that if I simply straighten the metal then it will bend back fairly easily. What’s the right way to go about fixing my bumper bar?

Any advice is appreciated.

Anybody using 320G/325G with auto sheet feed? - Posted September 24, 2006

Hello,
I have a 320G press (#17096) set up with the optional auto sheet feed and was wondering if anyone was using one of these presses. I am looking for replacement rubber tapes for its sheet advance mechanism and have yet to find a source. Any ideas? Any tips on working on this press from someone experienced with its operation?

Thanks,

Universal III press restoration… - Posted

Universal III #25942unicylinder.jpgbedextension.jpgderusted.jpgunipartsneeded.jpg

As time permits, I have been working to restore two Vandercook Universal III presses (#25942 and #27123) which I bought from a printing equipment dealer on the west coast and had freighted to me here in Brooklyn. I have been hounding poor Fritz with numerous questions and parts inquiries and thought it might be better to discuss my progress in this open forum so that others could put in their input and perhaps save NA Graphics and myself some time on the phone. Both of these presses are full power, have adjustable beds, ink monitor, ink reservoir, bed extension, tower, and automatic grippers.
So here I will mention a few things that have come up along the way and are as of yet unresolved.
First, I am in need of a metal feedboard edge and sheet side guide for one of these presses. This feedboard edge is also missing from Universal IIIs that are being restored by Fritz Klinke and Bryce Knudson. I am hoping that we can find a machinist that can make some for us for a decent price. Is anyone else in need of this part?
Second, I am in need of lockup bars for these presses, but so far I have only been able to find one for an SP20 which is an inch too wide. I can have it machined down, but would rather trade it for the correct part or I will probably just use it on one of my Vandercook 320Gs…

Here is the list of parts I am currently seeking for these presses:
1x Positive Lockup Bar or Dead Bar X-11645
1x Auto Frisket tower spring X-3550
2x Washup Tray X-17380
1x Sheet Side Guide B-26
1x Metal Feedboard Edge
1x Vibrator Crescent M-184
1x Adjustable Bed Scale X-6637
1x Adjustable Bed Scale X-6638
Adjustable bed output shaft and gears
Electrical Contact Points
Cycle Start Button
Roller Dust Cover Retaining Magnet
Gripper Lever Elbow

I will leave it at that for the moment, but I will be continuing to post regarding my progress on these presses and would very much appreciate any feedback, comments or encouragement. I have my work cut out for me!

Thanks,

SP-15 inking issues - Posted September 21, 2006

[Some comments in response to this post concern repair of the Adjustable Bed on Universal I -PM]

I have what seems to be an older model SP-15. It looks exactly like the photos of Vivian Leung’s SP-15, which I have swiped from Briar Press and posted below. It only has four grippers, and the roller height adjustment is a bit less evolved than the later models, which have a pin that intersects the roller height adjustment knob.

Simply put, I cannot get my rollers to adjust high enough. The best I can do is a quarter inch stripe on the roller adjustment guage. And when I have the rear form roller adjusted to its highest point, it no longer makes contact with the drum, so not only are they too low, but they seem too high as well! I spoke on the phone to Fritz about the knob problems, and he conjectured that perhaps someone had drilled into the well that the knobs sit in because perhaps at one point, the bed was missing the extra plate, and someone couldn’t think of any other way to get the rollers low enough. He thought a quick and dirty solution might be to stick something in the holes to raise the knob a bit higher to give it the range of play I need. Fritz, you were so generous with your time on the phone, I’d hate to bother you again, but I neglected to mention the drum issue when we spoke. Maybe this is a significant clue. I wonder if some adjustment to the carriage would fix both problems.

One last problem, which Fritz had a solution for, but since it’s such a common problem with SP15s, perhaps there is another solution out there: when I tighten the allen screws of the roller adjustment knobs, it does nothing to keep the knobs from slipping. Fritz thought the threads were stripped, and advised plumber’s tape. I haven’t tried it yet, but will the next time I feel brave enough to tackle printing on this press again.

And I am absolutely hiring you to work on this press, Paul, when you come up to Seattle in October.

Thanks,
Jenny Wilkson

Carriage Adjustments on SP15 to limit lateral movement - Posted

At the Mass Art Press (Massachusetts College of Art), we have two SP15s. Both have what seems to be significant lateral movement in the carriage. When the carriage is rolled beyond the feedboard over the bed, the carriage can be wiggled toward and away from the operator by…oh…lets say 24-36 pts.. I’m assuming this is not a feature of the press and can be adjusted/corrected, but how? I tried adjusting the large nuts at the base of the carriage and near the center on both sides of the press and this did not seem to have an effect, but I wasn’t able to get much leverage on them.


Galley Press? - Posted September 18, 2006

level-adjusting-feet.jpgHappy 9-18 Day. The owner of a No. 4T wants to know whether his press has a galley height bed. He mentions that the undercut is .070” and also wants to know the dimensions of the leveler feet, one of which is apparently missing.

The simpliest way to find out the height-to-paper of the press bed is to place a metal type sort on the bed against the bed bearer. If the face of the sort is level with the bearer then the press has either a .918” height-to-paper bed or it is a .968” bed with a .050” galley plate in place. This method will also work to calibrate an adjustable bed presses when the gauge is misaligned or otherwise damaged (e.g. Universal I).

The 4T was designed to pull transparency proofs in addition to standard repro proofs. It is my understanding that all of them have .070” cylinder undercuts.

The leveler feet, are simply large bolts fitted into the feet of the press and are only necessary when a press is installed on an uneven floor. The bolt is 3/4-10, meaning the diameter is 3/4” and the thread pitch is 10 to-the-inch. The length is 2” (excluding the head). A suitable bolt can be purchased at a hardware store, but the head and nut will have six sides instead of four.-PM


Welcome - Posted September 14, 2006

Paul Moxon and I kicked around the idea of doing a blog for Vandercook presses when he visited me in Silverton earlier this summer. I can hand set type, but the computer work is beyond me, so Paul has done all the work to set this up. We want to limit discussion to Vandercook primarily and other proof type presses. Discussion can range widely over that general subject area, and can include news about presses, problems, fixes, printing problems, etc., but we will limit discussion if it ventures into other areas or becomes nasty or obnoxious. We all have precious little time to wade through the general garbage that infects discussion groups in general.

My business is NA Graphics that I purchased from Hal Sterne and Tom Bell in 1996. Included were the remaining inventory of parts and plans from Vandersons, and Vandersons was the result of the remains of Vandercook & Sons that had sold to Illinois Tool Works in about 1967. Vandercook failed to keep pace with changing technology, and as the bottom dropped out of letterpress in the late 60s, the company began to flounder and posted its first substantial loss by 1972. Production ceased in 1975, and the remaining parts and service business became Vandersons. By the time Sterne and Bell purchased Vandersons, the company was on the verge of going out of business, literally within days, so to Hal and Tom must get the credit for arriving on the scene in the nick of time. Otherwise, we would have nothing in the way of support for these presses today. 

Paul’s Vandercook site reflects a vast amount of work, and he is constantly looking for new material. Mark Wilden originated the site and Paul has continued it with enthusiasm. This blog is to expand on that for the everday situations we all have and for perplexing problems that may have already been solved by someone else. Or new problems that we all can take a crack at–and I have all the backup drawings and information here in our office. I’m willing to share information, look up parts, etc., but do not furnish copies of any of the original Vandercook blueprints in our possession. That’s where I draw the line on assistance, though I often furnish information off those plans, and even sections of those plans. Some of the assembly drawings are 8 feet long, so there’s a limit to what I can actually furnish. Nothing has been digitized and short of some miracle, will remain undigitized. Our business is selling parts and supplies, and since my personal needs for food and  shelter are much like everyone else’s, I need to protect the source of my income.

I will attempt to post a couple of pictures I just took showing about half the file cabinets containing the Vandercook files, and then a shot of the files themselves, in this case the plan for the ink fountain for the SP-25. In true machine shop procedure, each part, including nuts and bolts, has a drawing, and then there are assembly drawings, and erection drawings, along with serial number books, plans for jigs and fixtures, engineering change orders, photos of products, historical material, etc. It has taken me nearly 10 years to feel comfortable with finding material within the thousands of pieces of paper in these files. –Fritz Klinke
