If the bushings are sized correctly, turn down to the bushing, until the wood is smooth with the bushings. Maybe even a little further depending on your finish. But for now I suggest just going to the bushings. Even with the bushings, thats why we use bushings, to be able to get the barrels to the correct diameter. A friction finish like EEE will not add a noticeable amount to the barrel. Those of us who use CA or lacquer maybe, may turn a little shy to allow for a few thousandths for the finish. A lot of my bushings are already worn down a little and help with that. An occasional check with the calipers never hurts either. Thats to check the barrels and the bushings. It's not a bad idea to compare the bushings with the kits components from time to time also. Check to see that the diameters are close to each other. After a while, you learn which suppliers stuff matches what etc. Like Paul said, experience is the best teacher. Just have fun and don't be afraid to ask questions here. Good luck and welcome to the obsession.
