I was restyling an old White pine and I had the opportunity to steam bend (but that's not exactly what we did) a jin.
I thought I'd share the process.
First image is of the tree before any styling.
Second image shows that I removed the large front branch.
Third image shows that the jin is parallel to the first branch, which design wise is problematic.
Forth image shows plastic protecting the pot and branches from hot water and steam.
Fifth image shows the jin slightly refined and wired prior to the bend.
Sixth image shows the container of boiling water on kerosene stove.
Seventh image is of the the final result after bend and full wiring.
After preparing and wiring the jin, I simply held the tree over the boiling water, while submerging the jins in the water for about five minutes. I quickly placed the tree back on the stand and bent the wires appropriately. They certainly softened up from being in the hot water. I'm slightly skeptical about whether they will hold or not, but my teacher swears that when I remove the wire in about a month the jins position will remain.
I'll re-post the results after the wire is removed.
Hope this was useful or interesting for some of you.
