While cleaning my SP-20, I’ve found that one of the bearer rails is fairly deeply grooved and pitted. I’ve cleaned it several times and I keep pulling up grime and a lot of metal shavings, so it will take a few more passes. The roller that rides on it isn’t pitted. It’s just covered in grime and oil from the rail, and I’m still cleaning it.
I haven’t run the press yet to check impression. If the rail does cause impression problems, what should I check first, and what are the options for fixing it or working around it? The other bearer rail is almost spotless.
