It's been a quest for a great cuttable, removable with high enough tack mask for lettering (V carving). After 4 tries I finally found it.....Oramask 813 stencil film. Works great on lettering down to 5mm high, haven't tried smaller. It's semi-transparent blue which helps you see how well you squeegeed it before cutting. Can buy it on Amazon, not expensive. Had to share this.

Thanks for the post Ricko. What problems have you had with other masking materials?

Low adhesion and poor machine-ability, most noticed in " M,N,W,e" 5mm height and smaller with single flute V bits (any angle).

Just a note, to prevent paint from undermining the film (wicking up the grain), I first sand the surface all the way to 320 grit and spray a light film of clear enamel. After the paint in the V carved area dries after machining, film is the removed then I give it a light sand with 320, blow dust off and coat with whatever finish I'm using. This last sand removes any high ridges caused by Vcarving.

This is what I have found works best. For larger projects that I'm not making any money on I use masking tape and sand the work, but I use this for my tap handles that have fine lettering on them and it V-Carves awesome.
