Merry Christmas One and All,
I was goofing around between wrapping Christmas presents and putting
ornaments on the tree and ended up epoxying something that broke. I
like to use 4 to 1 epoxies, the stuff I get is from Tap plastics here in
California. It seems pretty similar in characteristics to the West
Well, since it's 4 to 1 it's a bit of a nuisance to mix properly so I
usually end up making a batch that's about 12.5 cc's because I use those
disposable plastic medicine cups you find at the hobby store. There is
a 2.5 cc mark and I guess at the 12.5 cc since it's halfway between 10
cc mark and 15 cc mark on the cup. I have been told that I can weigh it
but my scale is not that accurate so I'm either stuck with a largish
batch or I have to use 1 to 1 which doesn't seem to be as robust but is
easier to mix accurately. If someone has smaller cheaper accurate cups
or spoons please let me know.
First I mix it up good then I split the batch in two if it happens to be
too much and freeze half for later. Then I dump the half I'm using on
the top sheet of a legal pad of paper with wax paper between the sheets.
That way I can add the goodies I need like cab-o-sil or milled
fiberglass or microballoons and mix it up well. When the paper is
covered or too goopy after a couple of batches I tear off the top sheet
and move the wax paper down one. This is getting way longer than I
So here I need a ***y bit of epoxy, I have this pad of paper, so I
thought what if I used quad rule paper, the kind with vertical and
horizontal lines, then I would know (sort of) how much area the epoxy
covered and could (sort of) calculate the ratio. I squirted out the A
resin component, counted how many boxes it covered once it had spread
out, divided the number boxes by four and added that much of the B
catalyst to the paper next to the A. Yes it is not as accurate as
measuring in a cup, spoon, dropper or weighing but it seemed to work in
this particular pinch.
Just thought I'd pass that along. I was reminded of a story while I was
writing this. I was working with this Englishman, Tom Leppere, and we
happened to see a huge flock of blackbirds winging overhead. He says to
me "There are 346 birds in that flock" Of course I said "How in the
world do you know that?" To which he replied, "It's easy, just count
their feet and divide by two!"
Happy New Year To You Too!
