Parts for chi ishi
1 wooden dowel with a 1inch diameter (cut to 18 inches)
4 screws at least 1 inch long each
1 bag of quick dry mortar or cement (one bag will give you much more than you need. I'd ask around and see if someone you know has extra)
1 plastic container per chi ishi (cool whip containers are a pretty good size. My personal set use plastic containers that take-out Chinese soup was in)
tools (saw, screwdriver, water)
Steps...
1) Cut the dowel into 18 inch sections. Try to make each end of it as flat as possible.
2) Drive the 4 screws into it, each about 90 degrees from the last one. (I usually have two on opposite sides about 1/2 inch up from the bottom, and the other two about 1 inch up from the bottom so the screws don't intersect accidentally)
3)Follow the directions to make to quick dry cement.
4)Pour it into the plastic container with the dowel and screws standing up straight. Hold it up straight if needed, otherwise your chi ishi will have a lopsided handle which wouldn't effect how it works, but isn't ideal.
5)Hold it all still until it dries enough that the handle wont move.
6)Wait. This step should be relatively easy.
If the cement begins to crumble, just wrap the entire cement portion with anything from plastic wrap, to duct tape to keep the cement crumbs from falling onto you while training.
Above is a diagram of how to use them. The words are not in English but it's pretty self explanatory. One thing to remember is to bend your knees and exhale as you complete each movement.
*Note* I think that the words in the picture above are in Spanish. If anyone is fluent and would like to help out, feel free to translate the information and post it in the comments section.

http://okinawadojo.blogspot.com/2007/03/el-chi-ishi.html This is the website where the original image was posted. That's not where I found it, but I was able to track it down in addition to the following pictures and descriptions.
I humbly request that the anonymous poster who translated the first portion share their knowledge with us and do a bit more translating. The pictures came from Argentina originally. I'm not sure if knowing the particular dialect would help.
