I recently acquired a used Calumet 16x20 print washer, which is in decent shape, with one exception: the cylinders on the inside of the washer (not the flexible tubes on the outside) which distribute the water into the print chamber have many small cracks in them, some of which leak a little water into the overflow compartment.
What would have caused these tubes to crack this way?
I had the thought of maybe removing the external tubing, drying out the chambers, and then using a long swab with some epoxy to repair the cracks from the inside. I would use toothpicks in the exit holes to avoid accidentally sealing them. Does anyone have any advice/experience on something like this?
Thanks for your help. If I can get this thing back in business it would really speed up my workflow.
