Re: [PPLetterpress] Re: Question about Vandercook 4 roller cores
- Eric is correct about the pins--they don't come with the #4 core. The small slot in the new core that the threaded pin fits through may need a little filing to make everything slide properly.

> Are there different kinds or styles of these roller cores? My reason for asking is that I purchased a new set of cores (from Fritz) in order to have 2 sets of rollers. When I replaced my existing rollers with the new ones on the press today, all of a sudden the rollers would not turn as I traveled down the bed. The new cores do look different than my previous ones, an example of this difference would be that the new cores do not have the pin that retracts on the gear side of the form. Make any sense? Soooo, I put the old rollers back on and the form rollers turned again, just like magic. Any thoughts???
Bethany, the pins are not part of the roller cores, any more than the gears, springs, etc. are. You need to take those parts off the old rollers and put them on the new rollers, unless you have enough parts for both sets of rollers. When you send in cores for recovering, you should remove all bearings, pins, gears etc. The roller company just can't be expected to save everything.
If the new cores have the hole for the pin, then they are No. 4 cores; I don't think any other model uses that design. (If no hole for pin, they are something else.) There are often slight differences between cores made at different times, and I've seen pins that worked in one set of cores not work in another set because the pins were worn too short: had to get new pins then.
