: Glad to hear that you've gone back and done a "proper" repair on
: this and not just cut and sand elsewhere to force things to fit. :)

Me too.

: If you can't find premeasured cups then these will work just fine. Get
: something you know to be measured accurately and pour measured amounts
: into your cups and mark them on the outside with a marker.

you can generate measuring cups with the correct ratio pretty easy. althouh it may be a bit confusing in the discription. What you end up with is a two cup measuring system, where one cup fits in side the marked cup, and you replace the inside cup with each new epoxy batch. You can make up measuring cups for pretty much any size of epoxy.

here's how you get the measuring cup of a x:1 ratio.

1) put about 1/x of the desired amount of coloured water in one cup. (the first cup)
2) place the cup on a level surface, and mark the water level on the cup. Remember Chemestry 10, and mark the bottom of the miniskus (however you spell it) Marking it on four points will help read the marks later.
3) put the now marked cup inside another one.
4) transfer the mark to the outside cup (the second cup)

5) Dump the contents of water into a 3rd cup.
6) fill the first cup again to the mark, remember align the miniskus with the mark, ensure it is level when you check. Then dump this into the third cup again.
7) Repeat Step 6, the same x times (same number as the ratio you want) that is if the ratio is 2:1 do it a total of twice, if it is 5:1 do it a total of 5 times, if it is 1:1 skip this step.

8) Mark the miniskus on the second cup, now full of liquid.

9) put the second cup into the third cup, and transfer the line to the cup.

do keep the first and second cups incase you need to make a new measuring cup. maybe mark them, so you know they are a pair.

So now you have a cup that will give you a x:1 ratio. Each time you want a batch put a cup inside it, fill the hardener to the lower mark, and the resin to the higher mark. Away you go, if you are carful you should get lots of uses out of one measuring cup. If you are like me, you will make a mess of it,and have to make a new measuring cup once in a while.

I read this some where on the net, I'm not sure where though, it is a tip worth passing along... When using this method it is important that you be consistant in how far you push the inner cup into the measuring cup, as it will effect how much resin you put in the cup.

Optionally you may poke a hole at the measuring marks. Slide the inner cup in and use a pen to mark the inner cup each time you need a new batch of epoxy. This keeps the measuring cup away from the sticky epoxy when you are filling it.

cheers,

Myrl
