Between Ruthar's and Ukswrath's excellent builds, I have finally found the confidence to start cutting on my KB kit ... Cut out the chest plate, main shoulder bells, and bicep pieces, as well as started on the yoke, tonight.
Ukswrath, your recommendation of the high speed cutting wheel was on point. Makes cutting the plastic so straightforward (wish I had known about it when I was doing my styrene R2 build) ... Anyone about to start one of these builds, seriously consider using the HS cutting wheel, it chips out the plastic with nice clean cuts.
I will post some photos in the next day or so after I get more cutting done ...
