So this is the chest, not sure how accurate I will go with this, since the ODST chest will cover most of it.
I will have a little seem when it gets done, but again, that should be covered up by my ODST chest, but I will go step by step.
So here, I traced my template, then added a 10mm border around to account for the bevel to make it look thick, an optical illusion of sorts


Also bevel the back side of course, really hate trying to cover seems.
After that, I then rough cut an 45 degree angle on that 10mm edge border I gave the chest, sort out f like this, I saw
KaeSpoon do something similar to her chest piece and looked like some thicc armor, and loved that.




I know it looks rough right now, but took these outside 30 minutes ago with my dremel and smoothed it out, this is the result that of that




Then I moved the edge to see if I would get that thicc result like I wanted and yeah, I did.
Now about to smooth the edges further with some 600 grit and get it glued up, so until then, have a nice day
