We live in a Ponderosa Pine forest. I occasionally have a tree that is attacked by Pine Bark beetles. I took this tree down about 3 years ago and it had a fair amount of blue staining due to the beetle infestation. I cut up a bunch of blanks and sealed them. Been tripping over them ever since. :cool: So this is the first piece from that tree that I've turned.

So nice! Almost reminds me of Norfolk Island Pine! Chuck
I thought that also as I was working it. The sides of this bowl are thin enough to allow light through and that looked pretty cool. Gave a nice "glow" under the right sunlight conditions. Of course, you can't see that in any of the pictures posted ... :unknown:

Very interesting form also!
This is one of those projects that the native form drives the finish form. There were two limb intersections on this that I was trying to highlight.

Surprisingly, I had to do very little crack filling/repair work on this piece. Very stable and dry after 3-years. As I recall, I sealed these pieces within a day of cutting the tree down. I've been tripping over them ever since. :lol2:

That really is stellar from the wood, shape/form to the execution. I can’t wait to get it and I just have a special place for it…….:sarcastic:

Oh wow! We are also infested with those pesky beetles and I have a bunch of ponderosa...that is so pretty. I'll have to keep my eye out when I'm cutting out there!

Many large forest areas in Colorado have been totally devastated by these beetles. We still have millions of still standing dead trees in mountain areas ... big fire risk. I live east of the front range area (Colorado Springs) so we were not affected as much as the higher altitudes. That said, I've had several trees on our lot that did get infected and I took them down and disposed of them during the really cold months when the beetles were not spreading. They do spread the fungus into the trees which is what creates the blue stained look.

Beautiful! I've cut a bunch of that on my sawmill, it makes beautiful paneling also.
My entire shop has been paneled with horizontally installed T&G blue stain pine. It was going cheap and was readily available when the infestation was high (about 2007). Go figure ...

Beautiful bowl! Our previous home in north Georgia mountains had this “blue and buggy” T&G in basement ceiling. Love it, lightweight easy to use.

Found across the road this morning, courtesy of the beetles and the blue fungus spores they carry.

the black and white cookies and coffee are courtesy of @Arn213
From NYC, thank you sir !
I wanted him to send a little freckle faced redhead, but instead all I got were cookies ! But that's OK, I couldn't handle another one.

Hi @Steelart99 Your bowl is absolutely beautiful! I am amazed at how thin you were able to make it, given how soft the wood is and the knots and end grain. I still consider myself a beginner so I hope you don't mind if I ask a few questions... May I ask did you need to stabilize or harden the wood as you started to thin the walls? Did you use a hardener, epoxy, CA or something like that? Could you please share? Also, can I ask what is the thickness of the wall at the rim of the bowl and also at the point where the interior wall transitions into the curved bottom? Thank you for as much as you can share!

Joe @shadetree_1 - I just saw this and somehow missed it. My pleasure and red heads are magical creatures and the closes I can get to your request is the Irish Creme coffee…….you would have to find a pen pal in the Emerald Isle for a red head unicorn and there is not red head that can take the place of your late wife Linda. Enjoy and much peace.

Steven, I didn't have to stabilize this wood although I did do a few CA "repairs" on cracks as I was turning it down. Fewer than I thought might be needed. I used carbide lathe tools and took lots of small/light/slow passes to work the thickness down. That way, I don't put any large forces in any direction on the thinning wood. Patience is learned ... wanna see my pile of broken/cracked bowls? :blush:

Lathe speed is something I moderate as I feel how the wood is cutting; very subjective. Too high and there starts to be vibration as the walls thin and expand differently depending on the wood grain and density (knots are denser). Too slow and I'll get some grabbing that might tear out chunks.

By eyeball, the rim is somewhat less than 1/8" and the transition at the bottom is about 1/4". I try to keep the wall thickness the same all the way down to the bottom transition. That pretty much never happens, but I do try.

Of note, when this tree died from the beetle infestation, the sap drained down to the bottom of the tree while it was still standing. The lower sections are quite dense relative to the upper sections and still hold more sap-ish stuff.
