How do you measure 2-part epoxy?

Interesting that larger volume of epoxy doesn't need longer time to cure.
I have an unheated garage shop. I heat up a cup of water and sit my resin and hardener in hot water to get warm and thin out. After mixing, the warm glue flows well into nooks and crannies, but I let it cure in the cold overnight (maybe 40 degrees F). This has worked well in the past, but maybe I need more than 24 hours? Or is this just too cold?

Another point is that I currently color my glue black with laser printer toner, a very fine polyester powder. I assumed polyester will mix well with epoxy resin. I do mix well, to get the powder color and the hardener fully blended.

I've been drilling round holes for hidden tangs, maybe 1/2 inch diameter. Maybe I will try gouging out a slot, I have a Sawzall blade that I made into a thin scraping tool. Another option is to try burning a red hot tang into the handle block, as seen on Forged in Fire.

That’s to cold for proper curing. Live where it rarely gets down to 40 but I have a small floodlight that I point on the handle so it stays some 70 plus degrees for curing .. it has the best temp range on the info with G-Flex but all epoxies cure best at a comfortable room temp. Also just because you saw someone in a rush on FIF burn a tang into a block of wood, doesn’t mean it’s a smart way to do it. The charcoal inside the hole is not good material for epoxy to adhere to..Stick with the drill and sawsall scraper.. Have fun & stay safe!
 
I use a very accurate digital scale I got on amazon for my GFlex. For mixing I generally turn a beer can upside down and mix in the concave bottom.
 
That is was gummy and not well cured seems to point to the cold temperature being a possible problem.

One thing I always do is mix the epoxy in a plastic cup with a stir stick. Then I leave the cup and stick with the leftover epoxy next to the knife. When the epoxy in the cup is cured fully hard, then I know the same should be true of the epoxy in the knife handle.
 
I use a super high precision scale. Picked this bad boy up from a yard sale for $10. It was missing the pre weighted pan bottom so I had to fiddle with washers till I found the right weight withstand it started to read and zero out. This picture is with a 2 gram test weight on the scale. It will weight from zero to 100grams. I zeroed it out with a sticky note on it and then wrote hi on it and it would weight the weight of the ink, yeah crazy lol.
