Vandercook #4

Hi Paul. We’ve just purchased a Vandercook #4 we think it was originally owned by University of MN Duluth, serial #9903. We removed the carriage for transportation and will be following your directions for reassembly! While it is off we’ve been getting her all cleaned up and noticed that three of the steel carriage rollers turn easily, but the fourth one is very stiff and has almost a click as it turns. We are thinking of removing it and getting a look at the bearings…any suggestions or tips you can offer? Thanks much we are super stocked to have her!
