Title: My new Shimpaku
Post by: bwaynef on June 01, 2015, 01:36 PM
This one has changed through a few hands recently and when I had the opportunity, it quickly followed me home.  It was quite over-grown, but seemed very healthy.  I'd intended to repot it this spring, but that window lapsed and so it will continue in this pot  & soil for another year.

I noticed this spring that there were lots of inner branches that were starting to weaken/yellow, so this weekend I decided I'd open it up a bit.  This was simply to let more light in and hopefully strengthen some interior growth so I can compact this tree a good bit over the next few years.

I've got a couple of ideas as to the way forward with this one, but nothing that'd constitute a plan.  I'd be interested to hear what you have to say about it.

Hopefully leaving a branch growing to the rear.  

You could field grow it until the trunk bends swell together and keep all the curves.

wow.  I guess the repeating spiral(s) don't add that much, but I saw a little something different. 

I'll see what I can do with this one when I get some time.  If push comes to shove (what does that even MEAN?) I'll still be able to go in the direction of this virtual.

It's an opinion, and not my tree  :).  I'd love to see something novel done with it.

I kinda agree with Owen.  The barber pole, corkscrew twist in the basic tree is very bothering.  I'd differ a bit, though in only giving the tree one direction to grow in.

But . . . this too is but one person's opinion.

You canalso "crush" the tree using a jack, on a couple of axes compressing the spiral and redirecting parts of it. Then let it grow and pull it back in.

Kirby, that's closer to what I was hoping to do.

Agreed.  Something like this could be nice.

I'm pretty sure I'd need a few extra hands (and more expertise) to pull something like that off with this material.

Nope, a jack and some guy wires.

Have any recommendations for a jack?  If you don't have a URL handy, anything to look for?  Think China can make 'em as good as Japan?

Any reason this wouldn't suffice?: http://www.stonelantern.com/Extra_Large_Bonsai_Tree_Branch_Jack_p/tcbj6.htm (http://www.stonelantern.com/Extra_Large_Bonsai_Tree_Branch_Jack_p/tcbj6.htm)

Only one way to find out.  Make sure to use some sort of buffer material between the bark and the jack, something like a thick rubber, but I think the pressure on the trunk will be immense, so you may need a couple different materials to distribute the load.  I'm not sure exactly because I have not done any trunk splitting to do extreme bends on thick material, but this might be a good candidate if you do some investigation to see if others have done it with success.

Should be fine. You can cut an old garden hose to protect the trunk. Use tubing or hose to protect the guy wire points.

Brian Van Fleet posted to someone who was looking for something similar that he'd been less than impressed with the stone lantern jack.

Back to researching.  That link has a lead on another one that ought to be a little better.  We'll see what I can come up with.

Is there any danger in getting too large a jack?  I've found 14.5", 15.5" and 23.5" jacks.  The price increase isn't exactly linear, so I'm considering the largest one, though I'm unlikely to need that length in the short-term.  Will it be prohibitively large when working with smaller trees?

Whatever you do, I am watching this with interest.

I think there is loads of different routes to take on this but would love to see how it gets bent.

I got a new jack from Jonas @ http://bonsaitonight.com on the recommendation of @Adair M.

I didn't get a before picture mostly because I wasn't intending to actually do the work, but I ended up cranking the tree down what felt like a pretty good bit on one coil, but after looking at the previous pictures in this thread it may not've been as much as I thought.

I also started wiring out some branches, mostly to get them out of the way.  I don't have a front decided on and just wanted a better view of the trunk so I could start making decisions on the front.  I ended up wiring about 1/4 of the tree.  (There's something therapeutic in wiring.)

Maybe after I get the branches dealt with I can see the trunk better and determine where some other bends can take place.

Here are some updated photos after working with it again last night.

Yes, you want to use the smallest jack that will do the job. You see what we did with the little TOTM. If you mainly work with small or medium trees, get the medium jack. In the end I have ended up with 4......

Why the smallest jack that can do the job? Stability.
