How do you know all this cool stuff Frank? ;} I guess a alien ship builder has to be a jack of all traits. I'm a furniture maker, I use ever sharps. ;} Actually I did use a carpenters pencil today when I was tracing the shape of the horizontal base of my original Kittredge built MBT's today onto cardboard. I needed to make more accurate 3D models of them, and add the 2 to 1 heads into them, so I could obtain the volume of the MBT's when they are attached to the sub. The stern MBT is a little larger in some ways then the bow MBT, and a little smaller in some ways also. So it will remain to be seen if they hold the same volume. I'm not sure how the Captain figured out the volume, with all these odd 3D shapes. Perhaps it was just one of those make your best guess, and then trial and error things. It was nice to work on the bow MBT today, and continue the filler work, in preporation for making a master mold off of it.

That's very interesting. I'm glad you shared that with us.
I've not had a lot of experience with gouging. I have cut some flat plate, and removed a couple of fillet welds a few years ago. It takes some practice and I've seen some experienced guys get good results with the cut edge looking pretty clean. On par with a good oxy-acetylene job but in locations where gas cutting is impractical or impossible.
It's useful and like you say, if done properly imparts less heat into the base metal.
I have some carbon rod in the shop but mostly use it for brazing. It's like TIG but without the cover gas when used with silicon/bronze. Great for sticking thin sheet metal together. Pretty handy to keep around. The larger rods make good pencils too! Good for drawing on the floor when doing large lay-outs. Frank D.
