I have an old Clarkson. You can see a model of it here:

What lube do I use for the table ways?
If I don't use any, it does't attract grinding debris, but it doesn't move well either. I've used ordinary car engine oil and use more time cleaning than grinding. It's just for my own hobby tools, but would like to treat it kindly.
