Well, I found out why you can't buy the SRM-6 from a Thor separately.. it's moulded on to the upper torso. Bugger. Now if I chop it off, I'll have to repair the Thor if I want to use it (sans SRM).
On the plus side, my new Silhouette Portrait blade arrived today. I'm really hoping my other blade is a bit blunt and this is going to solve my problem cutting the 15 thousand plasticard.. because right now it only cuts 2/3rds of the way through, and doesn't even cut all the way through on 10 thou plasticard either. Getting it cutting all the way through is essential if I am going to detail all of my sci-fi corridor sections before the end of the year..
