Nice bowls, where are the knee deep curls?
Thanks!might leave base rustic but would sand that end grain tear out up near top near candle. Nice job.
Nice bowls. Oak is a favorite. Your sharp corners encourage cracks. There are known as stress risers. I usually cut mine sharp, as you have, but chamfer them. It makes a difference
Not Charles but good to know. Do you chamfer in toward the center at 45 degrees?chamfer them. It makes a difference
Thank you! Guess I need to throw them back on the lathe really quick. 🙂Nice bowls. Oak is a favorite. Your sharp corners encourage cracks. There are known as stress risers. I usually cut mine sharp, as you have, but chamfer them. It makes a difference
Alan and @Charles Cadenhead , Regarding the sharp corners, it’s quite easy and quick for a tiny tear to start, it’s just a bit of wood there. The stresses of drying will cause that tiny crack to run. If unchecked it can ruin an otherwise great star to a bowl.Not Charles but good to know. Do you chamfer in toward the center at 45 degrees?
Mark, you were right about those checks on the rim. These two bowls were turned last week and have been in a paper bag ever since and they still cracked. I returned the edges as you recommended and put them back in a bag. I hope that helps....Alan and @Charles Cadenhead , Regarding the sharp corners, it’s quite easy and quick for a tiny tear to start, it’s just a bit of wood there.

Strongest is a completely round form, weakest is a knife edge. Choose your risk and reward. A rounded 1st turning means there is a lot to remove at 2nd turning to achieved a nice form, and the sharp square, closer to your desired final shape invites cracks.
Ive opted for about an 1/8 inch radius to soften the edge. A 45 degree chamfer, and then soften the edges left from chamfering.
This is a 14 inch bowl 1st turned last nightView attachment 59682
Oak is a different creature. I love it even though it requires more care than most woods, or maybe because of that. I tend to be a sucker for challenges.

I love oak, though much of what I turn is dry white oak. Mostly for spindles. I'm familiar with splitting freshly cut oak since I also make Windsor chairs, although there all the shaping work is done with drawknife and spokeshave. That is great fun.Oak is a different creature. I love it even though it requires more care than most woods, or maybe because of that. I tend to be a sucker for challenges. My thoughts about oak;
For a very strong, heavy wood, it’s surprisingly weak between fibers. It can’t handle much tensile load there. Splitting oak for firewood is great fun because of this.
Also it seems to move rather quickly as it dries. Far too quickly considering the weak bonds between fibers. So, slow drying is essential. A paper bag just isn’t going to work, nor will a box with shavings. Anchorseal the entire bowl. Use it liberally, then apply strips of paper towel over the rim, about an inch, inch and a half down each side (inside and outside), and liberally coat with more anchorseal. Then you need to put it away, out of draughts and breezes, and leave it. It’s the slow way, but it works.
Pith down is stronger than pith up.
Last point is to have fun!
Nice burl! Unless the other side (headstock) is even nicer than this side (shown) I would reverse it. Especially if making a bowl - you don't want to turn away all that figure. But, I assume you already know that so the other side must be spectacular !Maple burl from “Got Wood’s” giveaway finally on the top of the pile. It’s on the lathe… now to figure out what to make
That’s tough. Very beautiful funnel though. I would imagine everyone here is a member of that club. Myself, multiple times haha.ruined a pretty piece of bocote
Never saw or turned Macadamia wood Michael, just looked it up and yes that is super special wood, does not grow here that is for sure, but that Honey Suckle HF wood (top right) is petty special to me as well.@Leo Van Der Loo gorgeous miniatures, thanks for sharing. I might have to turn a tiny little hollowform now too. One of the things I found interesting about Barberry was the rays, almost like Macadmia. Have a cool yellow-white color, which you can see well in your first photo.
Also kind of funny, I almost made a joke about this one being a type of wood that even Leo might not have turned. But when I thought about, I figured you probably had. 🙂 That’s a very nice story to go along with your Barberry experience.
I often do, now always will. I was going for a thin wall and tried to make good better. Been kicking myself since.use calipers
The Honey Suckle turns nicely, the problem with that wood is splitting, that wood has almost always splits in it, even while still growing.I noticed that one Leo, wry cool as well. The little spots are funky. Mini-bird eyes or tiny little burls. Looks like a nice coloration. Did it turn well?
What type of wood is that bulbous HF (to the right of the little Barberry)?
