I use syringes, Daniel. One syringe for epoxy, and a separate one for the hardener- that way you can reuse the syringes over and over again.
I pull the plunger out of the syringe and then fill the tube of the syringe until the epoxy settles at the measurement I want. Then I reinsert the plunger and push the contents into my mixing cup. Then do the same for the hardener. Same process as those who use the measure medicine cups, but I have trouble reading the graduations on those. The syringes are so much easier to for me to get a good measurement.
I use 10cc syringes because they are easy to find and cheap. I actually get them for about fifty cents each from the local pharmacy. If it's a new person at the pharmacy they ask me what I need syringes for, especially when I tell them I don't need the needle. When I tell them it's for mixing epoxy they look confused for about five seconds and then ask me how many I need.
