    Square hole drilling attachment, if someone didn't want to watch the video. Nice tool and would be fun to build BTW, the text looks like Japanese than Chinese, but I'm not 100% sure.
    Amount of experience is in direct proportion to the value of broken equipment.

      Ha! my bad, it is Japanese. Didn't have my glasses on, so just blur. Oh, you'd think I would have known... I worked for a Japanese company for over 10 years, and spent two in Tokyo

      Of course, as it's Japanese I probably can't afford one!

          i thought the characters were basically the same; a Chinese friend of mine tells of going to Japan and being able to read things but not converse?

          i liked the slow motion portion of that video, very clearly shows whats going on.....but I've not had to make enough square holes to entertain making one

            I have a Watts drill,but mine uses square templet holes for the drill to flop around in. Not sure how this one works. I didn't have the patience to watch the whole video as my knee is killing me. Must be built into the head somehow.

              Japanese uses 3 sets of characters-Hiragana, Katakana and Kanji.
              I think chinese only uses Kanji.

                Actually, the Watts brothers have been manufacturing the Watts Head for many years, right here in the USA. The Japanese or Chinese probably got their mitts on one and copied it. (Asians don't do too well with anybody's patent rights)

                I had to laugh, a couple of years ago. A friend was replacing a cylinder head on a GM 4.3L V-6 engine. Being a "net build" engine, all of the adjustments are set by very precise machining of the head, and they use "torque-to-yield" bolts to retain the head on the block. When he looked up the valve lash and head bolt torque, he discovered there were none. TTY bolts require the use of a "torque angle gage" to achieve correct bolt stretch. Instead of asking me if I had one, he drove to the local "VatoZone" and bought a "torque angle gage set" (Chinese made). He fooled around with it for a whole day, trying to figure out how to use it...no luck...no instruction sheet, either.
                He finally called me, wanting to know if it would be possible to torque the bolts to an older vehicle's torque, and be done with it. I told him that the newer head gasket materials and the TTY bolts were necessary to get the proper clamping and using older style bolts were inviting a failure. He then, sheepishly, asked me if I could show him how to work the angle gage he bought. Once at his place, I went to set up the gage, and soon discovered that the Chinese made gage was missing a couple of critical parts. And was impossible to use without them. Apparently, a Chinese purchasing agent had bought an incomplete torque angle gage from somebody, and shipped it back to China, where they manufactured several million of them for export.
                I got out my own torque angle gage (complete, Snap-on) and we got all of the bolts torqued correctly, and had a good laugh. My friend took the angle gage back to the store, and told them it was all but useless, and got his money back. But I can't help but wonder how many poor saps bought these things, not knowing.
                No good deed goes unpunished.

                    I use the cheap angle finder, the ratchet. lol Most TTY bolts go in 90 degree increments so I just line up the ratchet with the head and turn 90 degrees.

                      I think chinese only uses Kanji.

                      And... the official "in use"Japanese Kanji character set is vastly simpified. Less than 2000 are used plus a few hundred more for family names. The Chinese has over 80,000 as did the old Japanese set. It was reduced from the orginal Chinese and extend Japanese set in the '30s (IIRC) so the extended population people has a chance of becoming literate.

                      Japanese reuses kanji for multiple meanings depending on the context, so it's very hard for anyone else (including Japanese) to read it unless you have knowledge of the context. Hiragana is phonetic and the characters (like English letters) convey no meaning. Katakana is the same, but is generally reserved for foriegn words.

                      After two years of living there, I was lucky to be able to recognise the street and rail signs to get home

                        I couldn't tell, but was wondering if the "head" portion was cnc. Seems "controlled" rather than "flopping". The slow motion video sequence is interesting - nice corners.

                          Maybe, but if it was you would think they would have demonstrated making different sized holes.

                            What I can't figure out is how they index the head. All the square edges are nicely lined up in X and Y. The head would have to be adjustable but I just can't figure out the internals to allow for this adjustment. Maybe it's just a simple indexing set up? It would be interesting to see a engrish user manual.

                              That's why haikus are an art form. In the Japanese language, they can have multiple meanings; it's an art form to construct a good haiku.
