| Guest | Dave, Most impressive. have you cut these? Can you plug all these different colors into your laser program? I'm jealous. I can only give it "cut", "engrave" and "notes". | ||

The reason is I can have each color a different setting. for example I can have the black cut through the sheet and the red can be a much lower setting to engrave. The file you are looking at is for printing with the plans, the laser cut file is all black | ||

| Guest | Nice. I'll have to have another look at my laser. I'm usually running 100% on the cuts so I use one color for cutting and one color for etching, like you said. I never thought of using different power settings for different colors. I'm now working on the Mediator and the Matthew so I'll have a chance to do some fiddling shortly. Regards, Rick | ||

It is very helpful to preplan the steps of your build, otherwise like I had to do, I had to take things apart and make corrections. I remember Being told by Bob Bruckshaw "in model ship building not only do you have to learn how to build a model but also learn how to take them apart." My plan was to add the wales to the hull which would stabilize the framing, then cut the hull free of the jig. The wales take a bend and twist at the stern so by leaving the stern open I would have enough room to clamp the wales. Building a model ship is like working on a computer if something goes wrong and you don't know how to fix it your totally lost. Then someone comes along and with a few key strokes and clicks on the mouse everything is fixed. If you don't know how a ship is built or how a computer runs you can be left scratching your head wondering how to fix it, the answer is very simple if you have the information. In this case the stern of the General Hunter was missing the cheeks which i really don't know if they have a proper name I just call them the stern cheeks. Without the cheeks in place the ends of the wales have nothing to fasten to and are just out there flapping in the wind making the builder wonder how do the wales attach at the stern. There are a number of ways to finish off the sides of the stern and here are a few examples. The first two examples i tinted in the pieces i need to add to the General Hunter. On these two examples notice there is a structure built up to form the ships sides. The third photo shows a method of finishing the stern by starting with a heavy timber and shaping in the cheeks.   | ||

In this case there is no need for a structure to be built above the solid filler pieces. The last standing structures before the stern are the two stanchions.  Here is a link to an example of the finish of the stern timbers at the side of the hull. http://nautarch.tamu.edu/model/report3/images3/stern1-l.jpg here is a link to the second General Hunter video https://youtu.be/byjWgDrNZ4M | ||

First items to be installed is the foundation the deck will sit on which are two heavy timbers called the deck clamps. There was nothing at the wreck site that can give us a clue to the deck layout and construction. In this case the deck will be reconatructed from bits and pieces of historical data.  | ||

That is going to take some measurements and a little math starting with the historical records of what size cannons the General Hunter was armed with. We know there were 6 pounder cannons and 4 pound, and carronades. Task one is go measure a 6 pound cannon on its cariage to see how hight up the cannon is. Looking at the museum model a 4 pound cannon is just above the height of the caprail and a 6 pounder come up to about the middle of the caprail and railing. Just so happens i have a real 6 pound cannon to measure.   here we have it scaled down  | ||

As it turns out you can see at midship the clamp is the same height as the wale on the outside of the hull. The clamp does not follow the height of the wale at the bow and stern, at the ends it sweeps up slightly. As i mentioned early on in the build log these ship were not built from plans but rather by the numbers. As long as you know the numbers it is easy to figure out what goes where. I know the height of a 6 pound cannon because i measured one, what i need to know is how thick is deck planking and what is the size of a deck beam. There wasn't any deck structure at the wreck site so i need to dig deeper to find that information. Well lo and behold in the personal papers of William Bell he just happened to have the information i needed. Specifications for a ship of about 90 tons. That fits close enough for the General Hunter. If anyone knows what "hollow Waterways" are post it. I will need to know that when it comes time to install them.   | ||
