what is the secret to getting the end grain on both the interior and exterior of a bowl smooth? I'm using a scraper and getting the feather like shavings but the end grain always is rough and has some tearout. The degree of roughness seems to be related to the species and grain tightness. e.g in the past few days I turned a walnut, cherry and maple bowl. The end grain on the maple bowl I turned last night is much smoother than the walnut and cherry but still not great. I've seen posts about sanding in reverse (my lathe does not have reverse) and hand sanding with the grain. I also think i may have been running the lathe at a higher speed when I ran the scraper on the maple bowl so that may have contributed to it being smoother too? My problem there is, I don't have the greatest lathe and when I run at high speeds with a chuck (ie the bowl 4 inches from the headstock (have a spindle adapter too) ) I get alot of vibration in my headstock. The walnut and cherry bowl were larger diameter so the vibration was unbearable at higher speeds.
