Trunk/Branch bending tools
« on: July 17, 2012, 08:40 AM »
For those with experience performing bends that might need special tools, what do you use and recommend?  I've got rebar, but I figure there is a reason that folks use the fancy tools.  Does anyone have any experience making their own?  How'd that turn out?  Any instructions?

Thanks for the tips!

I've got one of these:  http://www.dallasbonsai.com/product-p/bb81.htm which does the hard work.  And two small versions of this
https://www.californiabonsai.com/product/masakuni-adjustable-branch-bender/  These are great for making bends along a branch, interior of the tree.  They provide great leverage.

Wayne,
what kind of bends are you trying to make? some of the really difficult bends can be made with the masakuni type bender posted above, but some may require heavy artillery- Rebar with iron pipe, wood fulcrum and heavy duty guy wires. Regardless,  I think 90 of the big bends can be made with, as Boon calls them "Jackie's (usually two linked together on big bends (for angles)) and a commercial bending bars. If you are an accomplished welder none of this looks together to assemble, but they are pretty inexpensive and rarely fail.......John

Good question Wayne. If I may tag along and add something to it. I can weld and also do blacksmithing, and am curious if anyone has used these benders, how could they be improved. It seems like the pressure points are extremely small. Larry

Bob, here (http://bonsaistudygroup.com/ponderosa-pine-discussion/ponderosa-pine-transformation/) is one from Akio Kondo 3 years ago, and yes the wire is still on and may be coming off soon. Also, Chris Johnson posted a nice little video of Suthin working on a shimpaku with a jack (I haven't found it yet, will look). The key point with all of these approaches is that guy/restraining wires are require to hold the bend in place, and appropriate protection has to be applied at the point of the bend.

Suthin is coming to DeepCut Bonsai Club (my home club), next year post-MABS... I'm debating whether to pick an eighty+ yr old chinese juniper I collected from a train station near me (they let me take 3, I swear :) or a 40+ kingsville (bartered 5 of these landscaped kingsville for the work of me building a retaining wall, not a bad deal since it was the first time I ever built one).

The reasons why I'm unsure are because
1.) the chinese juniper is his bread&butter species (as I understand it)
2.) shohin is his bread and butter size (as I've heard in my club)

 Not sure if you meant this one John, but this is an elegant little tool :) I would like to get one of these, anyone know a generic name for this?

The masakuni benders are good.  I use the red rubber covered one a lot (don't know the maker).  I'm bending an old jin with aluminum foil and a blow torch tomorrow  ;D.  I'll post the process on my blog and may link it here.  Super easy and all you need is a pair of pliers and a lighter.
