Matt had a good point about 3/8" ribs - they help you build faster especially if you have to cut out every rib. That can be a big consideration when building big ships. Of course, if the laser is doing the work you don't need to worry about that.
If a 1/4" ball bearing will smash through a rib, it likely failed the foam test first Yeah, yeah, I know over time things can get weaker
Wow, it's been a week and I'm surprised that no one else has said they want a Baltimore hull in 1/96. Mark's kits can't be beat! Carl
