I decided to worry about the left forearm later, and instead finish up on the part I was confident was right. I struggled to bring myself to cut it at first: I was always douubting that I did it correctly. But then I thought: as long as it looks good when the cover strips go on, it will be fine. So I got to prepping by clamping my metal ruler along the pencil line I made. Hey, what's that? Then I ran a blade down the part, using the ruler as a guide. After a while, the plastic could be easily snapped. I put the two together and my fears were assuaged: it all lined up! I used the portions I cut off to make inner shims. After that, I lightly sanded the shims and the areas to be glued with E6000. It was a little annoying to put together, as this glue isn't very sticky until it starts to dry. But some clamps, magnets, and a little tape later, and she's ready to sleep for 24 hours. Sent from my SM-G955U using Tapatalk
