I use a small digital scale now that I got at Office Depot for about 30 bucks and I will not go back to measuring by volume again.
I used to use syringes also when I measured the epoxy by volume, but instead of directly syringing the epoxy I used to use water in the syringes to get the volume markings I was looking for in a clear plastic cup then I would dry the cup and put the epoxy and hardener in to the marks I made. I also highly recommend saving your T-88 squeeze bottles to put your laminating epoxy in later or using ketchup and mustard bottles. The T-88 bottles clean out good with vinegar or acetone.

Hi Netters. For those that measure their epoxy by volume, I suggest instead of pumps use syringes. Go to the local drug store and buy a 50 ml syringe. They are cheep. Even though you may be using 1 volume to 1 volume of epoxy to hardener get different sized syringes. The reason is that sooner or later you will stick the epoxy syringe into the hardener by mistake. If the epoxy is a thick type, cut off the needle fitting and run a 3/16" drill into the end of the syringe. This will make it easy to draw up the thick epoxy. Next use a fine tipped black permanent marker to go over the volume markings on the side scale of the syringe. Otherwise the epoxy will gradually dissolve off the marking. Add a stripe of colored tape down one side and on the end of the piston. Cover the entire cylinder with clear cello tape. This will preserve the volume marking indefinitely. Stand the syringe in a can or jar after each use. Do the same with the hardener sysringe but use a different colored tape on it. I use plastic jars for the epoxy and hardener. Peanut butter jars (plastic) work well. Color code them too. It does not take long to estimate the volume of epoxy that you require for a particular job. Don't mix more than you require. Get a couple of small syringes too for small jobs. Get a pair of 5 ml, 10 ml and 20 ml syringes. This way you will always have the exact mixing ratios in your glue. With a syringe you can see that you have the required volume. You are not relying on a pump which might have sucked a bit of air around the piston or might not have been pushed all the way to the top or bottom of it's travel. And don't forget the gloves. Keep that epoxy off your skin. I think that the blue "Tyvec" gloves are the best. They are tougher than latex or vinyl gloves. Clean the gloves off with "varsol", hang them up to dry. Next time use "Baby Powder" on your hands before putting them on again. They will last a long time this way. Sorry if I got a bit wordy.
