Sorry Fubar-one, I just missed your post. Can you please explain :
1. what Xacto knife with #11 blade use for?
2. What's a single razor edge use for?
3. Why is it neccessary to have a T sanding block and what 3 different grit would be appropriate( I mean what # of grit on the sandpaper)
I don't think I can get the "Dead Center" here in thailand. But thanks any way
