For a casting resin I got EasyCast by Castin'Cast from Michael's hobby store. You could also find casting resin at a tile store. A measuring cup is an essential item. I picked up an inexpensive plastic cup at Walmart's. You might also need another cup. I have a bunch of red plastic cups like the one shown. The directions instructed that once the resin is mixed, to transfer the mixture to another cup for further mixing. I did this and then transferred the mix back into the measuring cup for pouring. Casting resin is some very sensitive stuff, so read the directions thoroughly and follow them to the tee! Have on hand a lot of mixing sticks and paper towels. Resin that drips will seep through paper and adhere to whatever surface you're working on, so be sure to use several layers of paper or wax paper. If any gets through, it will leave a thin layer of plastic which can be scraped off later.
Once the tailpieces are seated, allow the resin to settle for a bit and then carefully add some more, if needed. If there is any spill over, grab a mixing stick and push the resin towards the hole with the side of the stick - like a squeegy. If any resin gets on the upper ends of the tailpieces, wrap a paper towel around your finger and wipe downwards to remove it. Once the casting resin is poured, don't move the handles. Don't touch them for 24 hours. After that, if you want to move them to another place until the curing process is complete, don't pick them up by the tailpieces. Get under the handles and carefully carry them like that.
AND NOW FOR THE KILLER PART.......THE WAIT! The Casting Resin I got says that the resin is cured after 72 hours. I wanted to be absolutely sure that the resin was rock hard and didn't attempt to finish my Aikido Grip until at least 72 hours after the resin had been poured.
In the meantime, go to the Grip I page and find the Hand-Held Wrist Roller to see how to make the clamp.
8. The texture of rubber bands makes the best grip surface for this device. Get a wide rubber band and cut it to length. You can find wide rubber bands at office supply stores. I just happen to have some exercise bands I got which are next to useless when it comes to exercise, but they make great grip surfaces. I cut the bands to length and then laminated them to the finger and thumb surfaces of my Aikido Grip using super glue.
