No choke on the barrel.The finish is a mixture of True Oil,boiled linseed oil & turpentine.The first couple of coats,the wood really soaks the stuff in.I let it set for a couple of hours & then rub it back.I continue the process until the the desired finish is achieved.It is NOT a quick finish to apply.I don't really keep track,but probably 30+ coats.I use the same process on maple except I add a SMALL amount of stain to the mixture.The ratio is APPROXIMATELY equal parts True Oil & BLO with a dribble of turpentine.
