any of y'all doing any barrel fluting? I'm looking at picking up a rotary table what would be best a 6" or 8"? I think 6" would to the job and be easier to move around any input would be great.
This is a 8" vertex , I made the fixture plate from mi6 ? I think, the dowell pin in center is removable and used to center table under spindle, also to center a chuck that bolts to plate.
I use a dividing head with a chuck on it. Very seldom do I need flutes on a straight sided barrel. The dividing head is adjustable for angle as is the tailstock.
You don't need a rotary table or an indexer to flute a barrel. I made up some hex nuts for both ends of the barrel and use them for indexing. Clamp the barrel down directly to the mill table, use a coupla 5/8" dowels pressed snuggly into the T slots for a locating stops, and another positive stop on the end of the barrel.
Don't use a ball endmill....it will walk. Use a horizontal type cutter.
