Introduction
The tools on this page are spin-offs from several scientific drilling projects, including 'Suigetsu Varves 2006' (http://www.suigetsu.org/index.html), 'Suigetsu Varves 2014', and 'Comparative Studies on Ancient American Civilizations' (http://dendro.naruto-u.ac.jp/csaac/). If you want to purchase any of the products, or for any other questions, please contact Takeshi Nakagawa by Email (nakag(at)fc.ritsumei.ac.jp).
Computer programs developed by Takeshi are here.
*This new product replaces previous PolyCounter special keyboard (jpg) produced by Keytec.
Note: If you are desperate, you can buy 19 mm plastic LL-channel from us, which is specifically designed to be used with three-sided cubes (see below). However, you can find aluminum or plastic L-angles in a wide range of sizes either online or from your nearest hardware store. FYI, the formats thaw we often use include 12 x 12 x 1 mm, 15 x 15 x 1 mm, and 20 x 20 x 1 mm.
