Prevent or correct tool marks when turning

[krzink]

are` you using a single or double bearing quill ?

I have the Pro headstock.

I generally will make the general design with carbide, then switch to a skew chisel (prefer an oval) for exterior work. For interior I do like a long three bevel bowl chisel (lots of videos on how to make this grind), but more often will just use a carbide cup bit (aka a shear cutter) At $15 they are not cheap because I can’t touch them up with a diamond file, but give a decent finish on the inside of a bowl or goblet. I’ve found that the cup bit leaves a very nice finish, but needs a light touch.
The cup bits are available in different diameters from a wide variety of vendors. Personally I buy from AZCarbide, but that’s just because I found they had what I wanted in other carbide tips. Do a search and I presume you will find a good assortment.
Hope that helps.

Be well,
Ben

Just want to chime in to agree with what Paul (masonsailor2) said about reversing the grain direction as part of the sanding/finishing process. This is a very helpful step when trying to remove stubborn scratch marks. You can even rig up a tool rest to use when the work is on the outboard side of the headstock (on the MkV) and take very light cuts, which often helps clean up the surface nicely before you start sanding through the grits. The tool rest I made is two oak dowels turned to fit into the post holes, with a piece of dense mahogany attached to the top ends of the dowels, making an inverted U shape.

Hope this is helpful.
