Starting this topic to explore the FreeCAD program and discuss techniques to be used. Being relatively new to the 3D CAD scene, the approaches will be relatively simple and sometimes wrong and can be improved. The project used as an example is a hull model of the New England fishing schooner Adventure and supporting information from http://schooner-adventure.org/about-us/ and details from Howard Chapelle's "The American Fishing Schooner". At some point photographs of the real schooner will resolve details. The objectives of the project are to understand some techniques for getting the 3D hull built, to get as realistic rendering as possible, and explore the opportunities for 3D printing with various options. I have been inspired by some amazing work in other topics in this forum "CAD and 3D Modelling/Drafting Plans with Software". Attached is a current rendering with many unresolved issues. I plan to go back and show how this was assembled and then move forward on the issues. Hoping that this will be of interest and that others will contribute.
I have been very remiss in not posting this log. So let me make up for my omission. and please stay with me while I share my complicated story. In late July of 2018 a friend came to me and said "you build model boats don't you?" And when I said yes he handed me a piece of paper with a name and phone number on it. He said "Call this guy. he has money". And with that my adventure began. When I called the guy (his name is Mike) it turned out he is an instructor for a school that trains students for careers in the maritime industry. The school has a harbor tug that is approx. 70 years old and needs to be retired. They don't have a lot of money and came up with the idea of building a model of a tug as an inexpensive way to teach about a modern tug until they can raise the money for the real thing. So they offered me several $1000 to build this model and a fueling barge to go with it. They wanted a tug model that was approx. 4 feet long. As mentioned elsewhere in this site I have been learning Fusion 360 and experimenting with 3D printing. So I thought what a great opportunity to use these skills. Never in my wildest dreams could I have imagined what happened from here. Both good and bad. Thanks to this wonderful web site I already knew about someone who had used Fusion to make 6' long 3D printed Battleships. So my first contact was to get an estimate of what it would take and how long. I also knew that my good friend Dr. Per had much more experience in CAD than I have and reached out to him. So I won't go into all the details. but as it turned out This school is part of the federal government and it took several weeks to just get approval on how not to spend any US tax dollars to do this project. It took many more weeks to get connected to the company that designed the Tug. And finally with the help of an attorney and an NDA. We got to spend a day on board the tug here in Seattle and received partial plans. So the non modeling part of this project took 4 1/2 months. Neal was given 6 weeks to develop the CAD drawings and then we had a design review with the customer. All of this was completed 12/21/2018. And now we could start actually modeling. I should also mention that the project was being funded by donations from a 3rd party and it took a while but we got set up as a vendor to them and got paid an initial $500.00 to cover materials.
Not sure this has been mentioned here yet. I bought one for $560 AUD, so US would be around $500 or less I reckon (though it IS from China, so not sure how the price will go there for you guys now!...) Initial tests of its capability have been very impressive, the detail is astounding - the attached columns are 40mm high. Downside is that resin is a messy mediun and prints require post processing - washing in Isoproyl alcohol and then curing under UV (ie sitting out on the back deck in the sun for a bit), its also a bit fume-y so using it in the lounge room in front of the telly is not on - its a 'down the back shed' style tool. Also build size is limited, but I certainly see a use for it and will be happily mucking around with it for a while yet.
As it was the retired period from a 40 years period of tv, graphics, and 3d projects, i said it is time to test a second tool. The first was a laser and CNC tool. Now i bought a 3d printer to make from scratch, and i will show some tests. This are some of the first tests, working for the ship hobby. I also mede some "toys" for my granddaughter, just to see how to work. It seams it is a good tool, and to test parts for ships is excellent. I will show how i build, pictures and explanations soon Cristi
