When I introduced myself a few months ago, I mentioned that I planned on learning how to turn bowls this year. So I stopped by my local Woodcraft a few weeks ago and being Sunday with playoff games, the store was pretty dead. The guys behind the counter were bored so they talked me into a basic bowl turning class. Not bad: 4hrs on instruction for $65.
So here I am a few weeks later turning some bowls and I notice that my sanding is seems to be extremely subpar. No matter what grit I use, I can't get rid of the growth rings. I thought it was the wood (Ambrosia Maple) so I switched to Mesquite. Same problem. I've gone down to 80grit and used three full sheets of paper. That's about 45 minutes of sanding. Still have the rings. If it isn't an issue with my sanding, what could it be?
