I totally forgot how to do all of this so what should have taken a half hour took a few. But I did finally settle on scale. I enlarged 10% on the face and 20% on the side. It really was the only way to keep length and minimise thickness disruption. Now I need to remeasure and work on the weird grip.
Okay I forgot to publish so here is where I am now!
Next is to figure out the size of the diamonds to add them in and also make the emitter. But I forgot to have lunch and also my ribs are so sore I have to have a lie down.
