219 OS Carriage latch question

Posted May 11, 2012 by Widmark    125 views    10 Comments    Print Print   
Tags: Categories: 219 OS, Carriage Latch

I’ve been talking to Fritz about this and he suggested reaching out to see if anyone else may have some measurements. My 219 OS has a wooden block acting as the carriage latch. Now that my press is properly leveled it’s clear that the wood has worn away and it’s no longer holding the carriage back at the feedboard. See the attched photos:

and the video posted here:

Dave Seat leveled the press while making other adjustments and that was when this problem became clear. Using masking tape to attach a small wooden shim solved the problem, but it was obviously a temporary solution. Recently that shim has compressed more and the whole thing wasn’t working, so I taped a bit of leading on, and it seems to work better. The linked video shows me moving the carriage while the wood block has both the wooden shim and a 2 pt lead.

But I’d like a more serious fix. Fritz doesn’t have a record of the carriage latch working like this and assumes that block was once steel. He doesn’t have a specs of such a piece. Do any other 219 OS owners have something similar? Or any other models using this technique? Ideally it would be great to get some measurements to try to make a new one.

Would adjusting the screw lift the wooden block enough to make it work? I haven’t messed with that because I don’t know what I’d be messing with! I’d also rather have a block with the right shape that would lift up and push the carriage back to the feed board the appropriate amount.

Any thoughts/info is much appreciated, thank you.

Potter manual?

I had an inquiry for a manual for a Potter No. 3. Does anyone have one or know someone who might? I did direct this person to the Potter census and to ATF catalog pages posted on the old site.

Vandercook #4 Foot Pedal Problems

Posted April 28, 2012 by Friedrich    255 views    14 Comments    Print Print   
Tags: Vandercook 4 Foot Pedal Problems Categories: No. 4 & 215

Hello.

I’m afraid that I’m having issues with my Vandercook No. 4 (Model 14186).

I’ve looked and looked, but something isn’t connecting properly anymore to make the paper grippers raise when the foot pedal is pressed.

When the pedal is pressed the bumper block is bumping out about 1/8″ when not in connection with the carriage, but when the carriage is back at the feed board and the pedal is pressed the grippers are not lifting.

The paper grippers have gradually been getting lower, but until yesterday when they suddenly ceased opening all together I thought it was my imagination. I can find anything loose or broken. Would it be possible that perhaps just the MRS-106 spring just need to be replaced with a springier spring? Another part need to get shifted? I’ve tried to adjust the gripper trip lever by manipulating the set screw, but no luck.

Any help would be greatly appreciated – it’s about to make my printing operation considerably trickier.

Best,
Friedrich Kerksieck

Grafix Proof Press

Tags: Categories: Grafix

Revised. Thomas Gravemaker sent these photos of a German-made Grafix proof press used during a recent four day event at Officina Tipografica Novepunti in Besano, Italy. The fourth photo below shows a cylinder trip assembly similar to a Vandercook Universal (1958-76) or a No. 4 (1935-1960). Some Grafix models have an adjustable press bed. The manufacturer Haas & Kellhofer Maschenenfabrik, which began in 1924, was separated from the controlling company in 1975. The successor company, HKS Filtration-Technology GmbH, guesses that production might have started around 1957 and stopped in 1972-73. Like FAG and Korrex, few are known in North America.

No 4 Motor Vibrations

Posted April 26, 2012 by chris_dunnett    140 views    8 Comments    Print Print   
Tags: Categories: Motors, No. 4 & 215

Help! – our No 4 sounds like a freight train and can be heard two floors up.

Thinking the sound was possibly coming from the ink drum or chain, I removed the belt that connects the motor to the gear box, but no luck. The motor itself is quite (I disconnected it from the press and turned it on while it sat on the floor) but when attached to the press, it causes vibrations that make the metal cabnit resonate and the floor shake. The motor appears to be connected as per the diagram in the manual and the bolts that hold the motor base onto the underside of the gearbox have rubber washers.

Is anyone familiar with this problem? Would adding rubber to the points of contact where the motor/gearbox assembly attaches to the press frame help?

My suspicion is that the motor itself is to blame. When I’ve put my hand on it while it’s winding down, it feels as if the shaft is acentric – creating a wobble. The motor is a Dayton model 5K460A, 3/4 hp, 1725 rpm. Anyone have the same motor?

SP-15 Ink Drum Scratches/Resurfacing

Posted April 25, 2012 by Sylvia Chevrier    169 views    6 Comments    Print Print   
Tags: Categories: Ink drum, Inking System, SP series

I read with interest Ray Nichols’ prior post regarding the resurfacing of his SP-15′s ink drum. The drum on my own SP-15 is also scratched, presumably from the previous owner’s use of the automatic washup system (the blade was missing when I bought the press, and I haven’t replaced it). The scratches on the drum are not terribly deep, but can be felt when running a hand lightly across. I’ve always felt that my press requires more ink than it should to achieve decent coverage. I’ve never used another SP-15 other than this one, but both the No. 4′s I used in the past did not need nearly as much ink as my press seems to. Additionally, the rear form roller, which comes in contact with the drum, never seems to have as much ink on it as the front form roller, until about halfway through a day’s printing, when by then there is quite alot of ink on the press.

My question is– does a scratched drum contribute to inking problems? I would be very interested to know if Ray and any others who have done resurfacing have noticed consistently improved results.

Help me be sure about what I’m doing

Hello everyone,

I’d like your input please. I need to know…

Is NevrDull abrasive? I know their website says it’s not abrasive, but, does it remove steel from surfaces? I read somewhere, some time ago that whenever your cleaning fabric turns gray it means that there’s metal being removed.

Also.. Is a Nylon scouring pad like the green 3m kind, enough to remove steel? Is it abrasive to steel?

I want to know if I’ll get my equipment out of spec and tolerance if I use 3m pads to scrub and remove superficial rust. Or if NevrDull will get me out of spec.

Thanks very much.

Ergonomic concerns?

I doubt this has ever been discussed here before. A few years ago I went to a lecture by Claire Van Vliet (our Great Mother) and she mentioned the physical problems she inherited from printing on a Vandercook for some five decades. These were spinal in nature, as I recall. Never thought much about it before but I just found out, after some thirty-six years at the wheel, that my rotating cuff (right side) is shot. Not all that pleasant a pain. I’m assuming the worst. Vandercook love.

Unknown press markings

Posted April 5, 2012 by kyle van horn    209 views    5 Comments    Print Print   
Tags: Bed Stamps Categories: Serial numbers, SP series

Hello all -

You’d think that after 4 years of owning this press and scrubbing, cleaning, and rebuilding most parts of our SP20, I’d have seen everything. A few weeks ago I noticed a pair of markings on the non-operator side of our press.

Directly across the end of the press from the serial number and the inspector mark (J.HLAVIN), outside the bearer is the following CM stamp:

 

It’s not on the other, newer SP20 in our shop. Does anyone recognize it? Could it stand for Chicago Machinery (wild guess) or Craftsman Machine Co (sacrilege!)?

Is it from a sub-contractor or reseller?

Thanks all!

Enrique Woolfolk sent this ad from the August-September 1958 issue of Las Artes Gráficas en México (Vol. XI,  No. 67), which he says was the Mexican version of The Inland Printer. This Spanish language trade journal has 23 entries in WorldCat.

The most interesting bit of information in this ad may be the name of the selling agent: Papeleria San Agustin. This agent may be noted in the model/serial number cards at NA Graphics for Vandercooks exported to Mexico.

template to hand-cut tympan packing / top sheet?

Tags: packing, tympan Categories: Drawsheet & Packing, Universal series

i live in mexico city, and i can’t find tympan packing or drawsheets for my newly purchased vandercook universal 1. does anyone have any suggestions on how to make my own? a template that i could use to hand-cut would be amazing, and also any suggestions on what type of material i should use (gotta find it in spanish, but an english equivalent is a start) for the drawsheet as well as packing. when i worked at a letterpress studio back in 2003, we didn’t use the shiny mylar or rubber blankets, only the sheets that feel a little waxy, like parchment. thanks for your help.

this may be something i have to order next time i’m stateside, as from my reading it seems DIY packing can result in bad printing. or else order directly from na graphics and wait for the mexican post to deliver it (often months).

so much to learn with a new press, in a new country . . . !

Bearings on a No. 03

Posted March 15, 2012 by Enrique    216 views    1 Comment    Print Print   
Tags: bearings, no. 03 Categories: Bearings, Gravity (0, 01, 03, 099)

Hi everyone.
While restoring my no. 03 I noticed my bearings were a bit dry and you could feel the metal touching inside, which is, as I’ve been told a sign of the bearing being worn, or spent.
So I decided to replace them, but to my surprise these are not standard bearings you get at your bearing shop, no sir, seems like they were made by Federal for these presses only. Maybe I’m missing something, or they can only be ordered somewhere I don’t know of.
The closest fit was inner diameter, outer diameter, but instead of 15mm of thickness it was 13mm which fits short of the length on the eccentric.

Where do you recommend I look?

Thanks everyone.
