I have been playing for a while with an old lathe (XL I think) to try and produce a sort of T&C Grinder. Before I actually "ruin" the lathe can anyone tell me how important it is to provide protection for the slides. I can imagine that in industry where a machine would work for a living it is vital but for me, sharpening a few cutters a week, is it absolutely necessary? If I clean up regularly am I likely to get a reasonable life from my bits of scrap or will it be worn out quicker than I can build it.
