Purchased a few tools recently.
Some Jin and Shari/bark scraping tools I’ve already put to work on a big juniper. They work so good.

Purchased a new root slayer that is much more compact and travel ready than my other. I also purchased a new mini pick axe which will replace the little pick I’ve been using for years. Collected a lot of trees with that other pick, but the point keeps bending in our rocky clay soil.
They look like pottery tools.

call me a spendthrift but I bought two brake drums with 'patina' (years of rust)
hit up your local scrapyard or car repair shop? I mean look at the potential on this one

That looks like a nanban pot but how about heat conduction?
I know ceramic pots get pretty hot in the sun.
Would not it be interesting to do a side by side test of a breake drum and a ceramic pot about the same size both filled with bonsai mix sitting in the sun? Check and compare temps?
@WEI interested?

michael hagedorn had a few updates in his blog post on its properties:
“Surprisingly, the metal seems to keep the root ball at a more even temperature—not too cool, not too hot—than the ceramic. I didn’t expect this. But the ceramic pots are much hotter than the metal, in the danger range, in the sun in the summer…
Now 18 months in with some high heat it’s still feeling cooler than the ceramic pots, and the tree is very healthy. We’re going to do some temperature tests in the soil so it’s not all guesswork, but it has been a surprise so far.”

that’s the plan! I’ll report back on results when another heat wave hits. i’ll test in lower temp weather, since we’re getting low-mid 80s in the DMV area for the next 2 weeks

That would've been my guess from the start. The heavy steel is significantly more thermal mass than ceramic, so as long as you can get it cold it should be easy to keep it cold. If course that also means that once it gets hit it's a bit more than just a good watering to cool it down again.
Would be interesting to see how they work out in winter.

As a machinist, I would have guessed the same. The thermodynamic properties of metal are pretty high compared to ceramic.
It's why generally metal feels cool to the touch even if it is at room tempature. What you are feeling is the metal absorbing the heat from your hand. You wouldn't get that same feeling from a ceramic pot if it was sitting at room tempature since it is a better insulator.
Now in the flip side, I'd guess that during winter the metal container will become cold faster then a ceramic container (think of an aluminum can and how it can become frozen is a pretty short time vs other containers of the same density). The ceramic container should maintain a moderate temperature throughout the day and night vs the metals wild swings.

I have a thing for (true) Cedars. I have successfully grown Atlas Cedar, Himalayan Cedar, and Cedar of Lebanon from seed. However, I couldn’t seem to get any Cyprus Cedar to germinate. I got impatient and purchased a Cyprian Cedar (Cedrus libani var. brevifolia) from Forest Farm. Despite reassurances from two customer representatives that none of their stock was grafted, I was sent a tree with an obvious grafting scar. I was pissed but figured I’d hang on to the tree and see if the graft would be less noticeable with time. Once again, I’ve become impatient so, I bought a backup (ungrafted) Cedrus brevifolia from Cedar Rose Nursery.

same position, and also just picked the same material from cedar rose. Very difficult to find.

Your post made my bench expand. lol well that, and my low will power. I've been wanting some Cedar for awhile, now I have two on the way.

Purchase another hibiscus
This trunk it's very old and have rare shape. I like it. From wat I see, it's seem raft style.

Bought some new small pots from Chuck Iker. The plan is to plant some mini ferns in them. I have no plans to show any trees but I like the added variety on my benches.

Bought this pool stone, added the dipper and spout that I've had lying around for 15 years...bonsai tsukubai.
He is one of my favorites...
