|This is a design diagram. Not all parts are labeled but you can extrapolate measurements based on scale.|
The "1cm = 7 in." notation means that one centimeter on paper represents 7 inches in real scale.
This video let's you see the Kamae Guy dummy in use, but the unedited video lacks explaination of what is being shown, so I want to point out specific waza with relevant time points.
- Men-uchi (0:29) - While the user stikes a small men-uchi the dummy keeps chudan-no-kamae
- Kote-uchi (1:20) - Note that kote is more difficult with the dummy because A) the wire "arms" are an obstacle which could damage your shinai and B) the padded hand clamp is in line with the shinai instead of being angled to the sides like a human's hands.
- Dou-uchi (1:25) - Because of the forward mast for the front it is easier to practice dou strikes from the back side (though you do not get the benefit of a partner in kamae). After striking with zanshin you can return to front by using a men or dou strike on the back side.
- Kote-Men (1:40) - For consecutive strikes, the shinai is going to be moving after the first strike so it will be an obstacle to consider as you move through subsequent strikes. A stationary dummy is good for ni-dan (two step) waza but more complex waza involving an advancing or retreating partner are harder to emulate.
- Suriage-Men (2:00) - Shikake waza that involve creating an opening in your opponents kamae are the main practical point of this dummy. The user must develop the power, control and timing for these waza
- Uchi-otoshi (3:00) - By using enough force and/or applying a good follow through to uchi-otoshi to effectively alter the "partner's" position, you will see that the shinai locks into a resting position.
- Hayasuburi/ Resting position (3:07) - While the dummy is in the resting position you can practice kihon men from either side. If you are practicing hayasuburi with the dummy in front you should be careful; if the dummy's shinai is moved past the locking point then the wires will uncross and the springs will pull the shinai back to chudan (with initial over correction as the springs return to equilibrium) quickly.
- Tsuba-zeria / hiki-waza (3:40) - When pressing Kamae Guy into a tsuba-zeria position, the heavy bottom spring will be trying to pull the shinai back down into chudan-no-kamae. For this reason, you will need to practice hiki-waza with knowledge that the dummy's shinai may come down on your head if you are too slow (the shinai will come down faster and harder if the springs are set at higher tension).
- Tsuki (4:10) - When striking tsuki against Kamae Guy you will note that the head tilts back slightly.
- However, as the pivot point where the top connects to the bottom rotates a little this seems to stress the wood so later designs could benefit from support blocks similar to the two on the front in order to prevent the wood from splitting.
- Tsuki-Men (7:47) - As the head is being pressed back a user could practice following up with men after tsuki as the artificial spine is recoiling.
- Gyaku-dou (7:26) - From the front, it is difficult to practice dou because of the springs but you can practice hiki-dou.
