Paul,
I am glad I read this post. I did not know that Terrco discontinued the K-Star. I immediately gaave them a call and ordered aspare drive belt. All the other wear parts look pretty standard. I have not had to replace anything on this machine except for cutters, it has been a stellar machine. With some modifications I think you could use the Carvemaster prop carver and maybe the model 1. I had to modify my Terrco machine when I originally purchased it 20+ years ago, man how time flies, and I updated the modifications a couple of years ago. If you want to talk sometime, I would be more than willing to share whatever information you would like to extract from my little pea brain.
