Process Refinement


As anticipated, my Icing order arrived yesterday. When I got off work I mixed up the smallest batch I could measure (49g paste, 1g hardner) and applied it to my rocket. Unfortunately the working time for this stuff is very short and it quickly started setting up on me, to the point that I got less than half of it applied to the rocket. What I did get applied ended up being thicker than I wanted in many places and got botched in one area, as I tried working it too long. The net result is I'm going to end up sanding off most of what I got applied! I spent a fair bit of time sanding yesterday, until my hands hurt too much for me to continue. More sanding this afternoon, time permitting.

Obviously I need to mix smaller batches. Since my current scale only measures in increments of grams I really have no choice but to purchase a new scale. I've had such a scale in my Amazon wishlist for a long time, as I'd already determined I needed one for weighing black powder ejection charges. I placed an order this morning for a scale, but not the one I had saved. The one I ordered has twice the range of the one I had saved, 200g, while having the same resolution, .01g. I should be able to mix very small batches now, if I need to.

To help ensure accuracy of the scale I also purchased a 200g calibration weight. I just hope the weight is accurate. While the vast majority of reviews on Amazon praise the weight, you will always find those that complain. If the complaints are accurate there are times these weights aren't worth using for fish sinkers! I'll just have to use my best judgement when it all arrives.
