An excellent tip Sir.
I always use digital kitchen scales for weighing the resin and a syringe for the catylyst.
Another very useful tip is to wrap the scales in clingfilm so they can be returned to the kitchen drawer and the catering department will be none the wiser to there recent usage

Unfortunately,
our kitchen scales are spring operated. I have however got a good stock of McDonald sticks.

All this modern stuff will never catch on. Stick to what you know works ....... they'll be making LED light bulbs instead of proper filament bulbs next

They should be reasonably accurate, i would still clingfilm the scales though. My wife has a lovely new set of digital scales for the kitchen and i have the ones i thought would be cleaned with acetone

I use a digital scale inside a ziplock bag. Works well, provided the scales have press button not touch sensitive controls... For the catalyst, I use a set of kitchen measuring spoons, which go down to 1ml. They're stainless steel and live in my tool box, so no chance of them being used for cooking.

I know you all know this, but just in case you don't - when using catalyst, be sure to WEAR SAFETY GLASSES.
Have a read on some of the delightful properties of MEKP, "MEKP is a severe skin irritant and can cause progressive corrosive damage or blindness."

Even as a 30-something software engineer, I have and prefer balance scales like that for cooking. Much easier to simply put on the weight you want and then pour the ingredient in until it goes "bonk".
I did buy a set of metric weights recently though, to save converting (on my iPhone
) when recipes don't include Imperial Pete

Digital scales with 1gm accuracy for époxy. For the OP with polyester, rough volume measurement then catalyst with a syringe (also volume..) Though within 1 to 2% for the mix. You guys with 4% must work fast ;o), or live oop norf.
'Er Inside has a spring balance kitchen scale. Don't think she has cottoned on to the fancy one out in the w/shop. I do have a really fancy 0-20kg electronic scale, but it is not good at the very low mixes for small jobs with époxy. Think it might be 5gm accurate.

Slight thread drift but not totally off topic. 15 years ago I bought a couple of 1/2 gallon tins of Marine Polyester resin cheap at a boat auction in Stockport. Wishing to make some substantial backing pads I used the old resin but with new MEK cat and cloth and matt that was in the garage for years. I used 1.8% by volume in a syringe and it soon went off and hard. I tested a piece of the 12mm laminate to destruction in a vice with a hammer after a few days curing. I was very impressed with how hard it was to destroy this with a lump hammer. I was also pleased how the resin had not solidified at the bottom of the can, although the cans are starting to show signs of seepage at the bottom seams where it had a bit of condensation off the concrete.
floor. I will now decant the other can and the rest of the one I used into a plastic container for future non-critical use!

These things are dead easy and no need to keep filling a syringe or pipette, just give the bottle a squeeze till the right amount is in the top tube and pour it in, tube is graduated and easy to read, use with a graduated mixing pot and it's quick and easy.
