You’re quite welcome, as I said, it’s a bit of pay back for teacher that sparked my interest in history many years ago.

After the model of the one that is going to be torpedoed is built, will there be an actual simulation of the torpedoing that will happen in the field behind the school? You can then take the pieces and use those in the display.
Wear safety glasses as rivets will be flying everywhere. A live webcast of the "science" project will be expected. Thanks Guns. |

But looking good! You want a LONG and Wide DuraBlock to bend the surface in a uniform way across a curve. They're like $25, but let you only need to sand once or twice once even pressure is used at maximum sandpaper coverage. Use Stick on 120 grit then 320 for final lines to not remove more than sanding marks, 120 and cheese graters for the extra filler that always ends up sticking up. Only go to the 330 to remove sanding marks of the 120, not for shaping. Fast is actually better, see video, long swipes. Go the long way with even pressure, don't go up and down unless it's a wide double curve like a windshield.

That 3 shaft drive is a total PITA, and it isn't a clock you can just replace the movement in for $5 (I'm assuming it has central control). If you really want to, mark where each one is, pry off, then put them back exactly to there's splines they were at, there's mini crowbar for doing that but I don't have advice for smaller mechanical bits like this. |

There are two Liberty Ships that have been restored: Jeremiah O'Brien in San Francisco and I think the John Brown on the East Coast. The O'Brien was restored in time to participate in the 50th anniversary of D-Day in Normandy.
The smaller one could have Stephens Hopkins which was noted for sinking a German hilfskreuzer (auxilary cruiser or merchant raider). While the ships were merchant marine, they had a contingent of USN Reserve personnel (US Navy Armed Guards) that crewed the guns. In a mutually fatal combat, the Stephen Hopkins sank the KMS Hilfskreuzer Stier. BTW, I had an optical boresighter for the 20 mm Oerlikon that I donated to the O'Brien. |

Not having followed this at all, I am very much day late/dollar short here. The bow does look off; in fact, it looks more like the profile of a Victory than a Liberty. Frame spacing looks ok but the vertical doesn't appear quite right to me. The best overall drawings I've yet found are the HAER drawings, which you may already have:
Victory ship Winthrop Victory Liberty ship Arthur Huddell The latter being a pipe laying vessel but the hull profile should be about the same. |

View Quote I agree with you. Hopefully Monday I can get a few kids to look closer at the bow and determine what we are doing wrong. Like i said, I did a quick check on the "Bow #1" frame and it was right. Seems really high. |

That is not looked at favorably. My students have learned to go down the hall and close all the doors when we start that up. We have a pretty good time most days in class, so it tends to be loud anyway. Music, banter, laughter...... people don't like that when they are lecturing.

It will help to close in the bow if you cut a profile of the stem (perpendicular to the frames) and attach it so that your ribbands aren't ending in space. It also gives definition to the forefoot (area where the stem makes the turn into the keel), so it will be easier when you add the plating.
