Smartborer demonstration at a forest near Tucson Arizona.

posted Feb 11, 2019, 1:44 PM by Smart Borer

There was no problem coring juniper, but the oak in Arizona was very hard and 12-mm 
borer got broken. I have had a similar experience when coring tropical wood in Thailand.
We are already developing optional parts for coring such very hard hardwood to prevent 
breaking increment borers. If you are interested these optional parts, please contact me.

Japandendro2018 meeting in Tsukuba

posted Jun 30, 2018, 5:40 AM by Smart Borer   [ updated Jun 30, 2018, 5:41 AM ]

 There will be the Japandendro2018 meeting held on Dec.1st-3rd in Tsukuba, Japan. The venue is FFPRI in Tsukuba and we will organize Smartborer training on 3rd, where you can experience coring Himalayan cedar and Zelkova serrata growing in the FFPRI campus, using Smartborer. There are a couple of foreigners joining from outside Japan and if there is a sufficient interest, we will organize a session in English. If you would like to join, please let me know (akagawa@ffpri.affrc.go.jp)!

Japandendro2018 website (in Japanese)

Many people have asked for video of Smartborer. And finally, we decided to make the video public, 
in which you can see how Smartborer looks like. Here is the link:

It was nice meeting you all in Bhutan and thank you for visiting our booth during Worlddendro2018!
If you need my help for sampling cores using Smartborer for your research, please let me know. 
As long as you can cover my travel expenses from Japan, I will be able to help your fieldwork. 
Right now, I have two confirmed requests and two potential requests from the Worlddendro2018 participants to join their fieldworks. If you are seriously thinking about purchasing Smartborer, I recommend you to try it on one of your fieldworks, because using Smartborer properly and safely requires some training, just like learning how to use increment borers. And this way you can check if it is 
what you really need for your work. Since the first purchase of Smartborer by my colleague, 
Masaki Sano, many Japanese scientists have seen Smartborer being used in our fieldworks, 
and then became convinced how useful the device can be. So far, more than ten Japanese 
scientists have already purchased Smartborer and are using them now for their core sampling. 
I am sure foreign scientists will find it as useful as Japanese scientists, and hopefully you 
will decide to introduce our device.

How to remove a stuck increment borer

posted Jun 7, 2018, 10:06 PM by Smart Borer   [ updated Jun 13, 2018, 9:46 AM ]

When increment borer gets stuck in wood, it is often difficult to 
extract the borer. This is especially the case if you are using 
12-mm borer and sampling hardwood cores. I had such a 
difficulty when coring oak in Hokkaido, Japan. 

To solve this problem, we have developed a 
new extractor for extracting 12-mm increment borer in collaboration 
with Neil Loader of Swansea University. The 12-mm 
extractor is based on 5-mm extractor (Loader NJ, Waterhouse JS 
(2014) An extractor device for stuck or broken increment bores. 
Tree-Ring Res 70(2):157–160).

Here is the Youtube video of our (old) prototype for extracting stuck 
12-mm borer.


Now we are testing a new version and we are almost ready to 
make it public.

Alternatively, stuck increment borer can be extracted by using Smartborer.
We have an optional socket named "clip socket", which has a clip similar to 
the one attached to increment borer handle. Using clip socket, 
increment borer can be fixed to the socket so that two (or three) people 
can pull the borer backward while one person 
reverses the borer. This way, you can quickly extract a stuck 
increment borer. If you wish, you can try both 12-mm borer extractor and 
the "clip socket" at my booth during Worlddendro2018.
