Last night I prepared for my first exopy session gluing the butt joints of my tern 14. I laid out the tape, mylar, bricks, etc., donned safety glasses, gloves, turned the music up and began pumping the resin without incident. I then pumped the hardener and heard two burps and saw an interruption of the stream. Beleiving that this might have put my ratio off I closed shop for the evening. My question is this - does anyone know where I can get accurate plastic (disposable - ie, cheap) graduated cups to allow mixing from as little as 1 1/2 ox. to 12 oz? System three sells 14 ounce graduated cups but they note that the accuracy may be questionable since the cups are rolled paper.

I was so ready to start but thought a little more patience was in order.

any thoughts? Thanks
