  1. With recent changes by Autodesk, the free version of Fusion360 can't save files to DXF, which you could use in most laser cutters. The paid version will allow this though- you make your sketch, generate solid parts from that, make a 2d drawing from the solid, and save an appropriate view as DXF. Regarding the print shops- you can have confidence in their printing ability the first time through. Unlike with the cheap filament printers, their processes are robust and well dialed-in. But yes, you do need to design a good part to begin with! And you need to be familiar with the main ty
  2. I used to have access to CATIA through work... but now retired, I must satisfy myself with Fusion360. In CATIA: Part of Fire Fighter in Fusion360:
  3. I've been designing and sourcing printed parts for some 11 years now. I still do not own a printer, as I don't want it to become the hobby itself. No interest in maintaining the equipment, tweaking it, and otherwise being encumbered by it, just to get sub-standard results. So I pay more and and just get my parts from pros, like Shapeways and Sculpteo. And these pros keep a stable of different types of printers, whatever is best suited for the job. FDM if you like making wicker chairs, multi-jet, true SLA, several flavors of SLS, and even waxes for investment cast parts. Have yet to pop for las
  4. Thanks Kurt. Indeed, and Wes Wheeler has big hopes for it. While he has detailed measurements from the original Pilar, the new boat differs in many significant ways... just as with the movie "replica" previously featured in Wooden Boat, it should not be used as a reference for models of the original Pilar. Much like BMW's version of the Mini vs. the original Mini Cooper!
  5. But don't look at it too closely, that's NOT Pilar. Another boat converted to loosely resemble Pilar, but wrong in major ways. Also don't look too closely at Wes Wheeler's modern interpretation of Pilar, it too is different in many ways, not at all a replica. Also don't look too closely at the thing in the BassPro shop in Florida, it is neither Pilar nor even a Wheeler.
  6. A while back I did a repair job on an Ingram towboat model, and noticed that it seemed to have a thick build of hard paint, which I assume was epoxy or automotive 2k. I imagine that a nice self-leveling epoxy could be an expedient way to achieve a smooth surface on a wood model of a steel boat. Does anyone know if this is a typical trick of the commercial trade? . Some of the damage, but the paint could take a beating! All better now
  7. It's becoming Winter, a time when I'd retreat to my well heated basement shop where I could only get a little glimpse of the slate gray skies through the little casement window yet could hear the sound of the howling wind resonating down the furnace flue.
  8. ...but here's the mid November view out my shop "window" in southern California I'll spare you the photo of me in shorts .
  9. Thanks. Cabin is cherry with Minwax Gunstock and spray can semigloss lacquer. Hull is fiberglass over basswood, primed and semigloss Rustoleum black, wet sanded and waxed (!)
  10. Any varnish could be used, builder's choice. But note that many details in this kit are completely wrong, including the finish shown on the box art. Hull should be black with a red bottom; transom MAY be varnished mahogany. I haven't confirmed what the cabin was... one source says mahogany (quite possible), and it may have been unstained early, and a darker stain later... the wood would be frequently refinished over the years. The kit represents the boat as it sat at Finca Vigia before its latest restoration, including later gaudy modifications that Hemingway likely never saw, and loss of cr
  11. The cabin walls, be sheeted in basswood, are subject to splitting over time due to humidity changes. So they receive the same fiberglass treatment as the hull. It's easy to deal with here, as the large surfaces are flat or simple convex. Windows are cut after walls are installed to ensure correct location. A simple template aids in marking out, and holes are opened and finished by Dremel, files, and sanding sticks. The aluminum sliding window frames will be installed later, likely made by printing. A sheet of 1/16" plywood covers the lower house... it seems big enough to double as a
  12. Main cabin is built up from frames and stringers, and sheeted in 1/16" basswood. The tricky corners are "planked" or covered with steam-bent sheet, depending on the radius. Traditional ship models are built from wood, often in a fashion that follows the prototype build method. If I wanted to keep that link to the prototype, I'd be rolling sheet metal skins here. It is possible- many modelers have built ships from soldered tinplate in the past. Today, modern ship modelers in Europe make use of thin phosphor bronze sheet. It's stronger than regular brass, allowing very thin gauges to
