Gunsmithing painting flutes

Re: painting flutes

sit down with sone blue painters tape, and some very very sharp exacto knives. and make sure that the barrel is already the color you want it. run the tape down the entire length of the barrel all the way around, dont make it too thick. and the cut out the fluting with the exacto knives. spray the flutes, and let it dry. at least, thats the way i would do it.
 
Re: painting flutes

From what I recall, you want to paint the whole barrel--try to go light--but even--in the flutes. Let flash to the point you can tape over it. Tape over the "Lands" and not the "Grooves" of the fluted barrel, overlapping the flutes. Then take a socket or something similar and press firmly and roll the down the flutes. The socket pressing aginst the tape at the edges of the flutes should serve to cleanly cut the tape and mask everything but the flutes.

Tape the bbl. then roll a marble or ballbearing down the flutes while pressing pretty hard. Ball bearing will score the tape & you peel off just the portion you need.
Semper Fi
 
Re: painting flutes

If your leaving the lands polished out, and just painting in the groves don't bother masking. Paint the entire thing then after it dries polish off the paint with a 3-4" wide strip of scotchbrite. with the groves sitting lower they should be left untouched. I'm doing this on my bench rifle with Cerakote, and will be using a barrel spinner and a fine belt on my grinder to polish it.
 
Re: painting flutes

i have another question along this line. i have a stainless barrel and i want to polish the flutes (make them shiny) and duracoat the rest of the barrel black. would i do the polishing, tape the flutes off using the blue tape and marble trick, spray, peel tape then cure? or is there a better way?
