Hey webwookie, would it be possible for you to add an isometric view of the bow block in the corner of the print somewhere?? Some of the rookie builders may not be proficient at reading prints, but with a "3D" view it may help them interpret what it should look like after it is done.
Not a problem; I'll put it in with the next iteration of that particular drawing. I've also uploaded the ribs on two 8.5x11 sheets in both pdf and dxf formats along with a pdf and dxf of the aft deck and some of the other 1/8" parts.
Cool[8D] The current DXFs (v1.01 I think) look awesome[]. I think you've done a great job on this project!!!!!!!! I do have a couple questions; It looks like a few ribs in the DXF file have an extra line around a portion of the outside perimeter, is this a remnant of the 3d rib which would have probably have shown an angle across the thickness of the rib?? I'm assuming that it's not necessary to cut these at an angle to perfectly match the hull contours??? Also, when I measured the notches that accept the ribs, they measure .250". In a perfect world this is great, but if I'm not mistaken, plywood is typically a considerable amount under it's stated thickness. I'm not at all experienced in putting one of these things together, so I don't know if it's beneficial or harmful to have these fit little more snugly? It may be too much trouble to address this, but I'll throw it out there in case you know of an easy way to deal with it.... (I know I don't): When I explode the ribs into it's basic forms in AutoCad, (arcs, lines splines etc) it seems that the bulk of the entities are either splines or lots and lots of short little lines. Of course, for a person who prints this out and pastes it to plywood to cut it out this will work just fine. However, if one were to attempt to cut them out on a CNC router or Laser, there would be one line of code for each tiny little line, resulting in a massive program, longer program creation time, and a longer run time if the equipment dosen't process fast enough. Not that it's impossible to work around, but if there is a fairly simple way to get the CAD to output longer straight lines and arcs, it would work better for production runs. Last question, How much time do you have into this so far?? IMHO, even if you don't do another minutes work on this, you have still done plenty to keep the hobby moving forward, and deserve a pat on the back!!
Yes, the doubled-lines is a remnant of the 3D geometry. I thought I had been able to clean up the views on the newest files but apparently I missed a few. If the parts are simply cut to the outermost profile, they can be given a slight taper with sandpaper or a file as needed by the individuals building each hull. Offhand, I didn't have access to nominal dimensions for 1/4" plywood so I figured it'd be best to keep the dimension to something recognizable (I'm also assuming most people will probably cut parts by hand anyways unless we do have somebody interested in laser cutting these for sale). I haven't attempted to do any geometric simplification or determine any ways of reducing the impact of the curves yielding a large CNC program; while I do have some CNC experience, I'll just leave any changes in that department to somebody who feels more comfortable working with the geometry and/or code in that way. So far, I think it's been about two full work-weeks worth of time (~80 hours), some of it multitasking between this and other projects. Somebody with dedicated time could probably do it in less.
The funky crap with wood dimensions is more a thing with cut wood (like a 2X4 isn't 2"X4"). Plywood is generally as advertised (i.e. 1/4" = 1/4") and this is especially true of nicer plywood. I order from Midwest or American Balsa (yes, they carry ply and it's exactly 1/4" (or whatever size you order).
I would recommend against going to the outermost profile of the ribs. The "sand it to shape" trick only works if you remember, and if you forget to then you end up with some funky-looking bulges. And believe me, people (especially rookies) will forget. It's safer to cut to the inside profile.
Note to all: build the Emilé Bertin according to these plans only with nicer plywood[]. On a more serious note, I've uploaded an updated bow block sheet and a sheet for the keels that has dimensions such that it could be printed out on multiple 8.5x11 sheets and taped/pasted together if absolutely necessary. Only the foredeck and foredeck subdeck have been giving me a bit of grief due to a minor issue with generating a flat pattern based upon the solid geometry.
You may want to consider rendering a set to legal sized paper. 8.5x14 means fewer sheets and less chance of error in the paste/tape phase. Most home printers can handle legal size with no problem.
Good point, since the dimensions yield a sheet that's 8" high, it's definitely possible to print on legal sized paper instead of 8.5x11. I haven't rendered it specifically for multiple pieces of paper yet; I've only verified that it can be subdivided accordingly.
Cannonman, Webwookie, I may have a rookie to test the Rookie Ship Design on. The Fire Marshal who was in charge of safety at the Maker Faire was so impressed with out sport that he said he would be interested in joining. If he shows up at our next battle, I plan to sell him my Spahkreuzer, RTR. I will also try to hook him up with the Emile Bertin, and help him build the hull and transfer Spahkreuzer's guts over to the new ship. If he isn't so interested, there may be other people interested in joining from the Maker Faire. What do you think?
I'm still quite confident that I can help out as we talked. I am into my Iowa at this time... I don't know if I'll have the design work done so everything is ready to cut by the end of this next coming weekend or not. If I could get the hull design work out of the way, I would be ready to cut during the following week. My gut feel is that I'll still have some lingering designing to do though. I'll try to step it up a bit. Webwookie..... Any guesstimate of when you might have design buttoned up on the Emile Bertin?? I'm not in any hurry, just trying to guage how much time I have to get my end done. I'll try to locate my stash of nicer plywood[]
Sounds like a good plan to get a new recruit onto the pond as quickly as possible. Does this mean that you'll be building another Spahkreuzer or shifting focus to other ships? With the exception of the forward deck and subdeck that I still have to convert over, the most recent versions of the dxf's for the hull parts are set to go if 2D data is suitable. As for 3D data, I have individual parts in Solid Edge V20 .par format at the moment in addition to the single (somewhat large) Unigraphics .prt file that I started with. Let me know if you'd like me to send over the source 3D data in either format (this is extended to anybody here on the forums, of course). I haven't had a chance to really sit down and start working on a superstructure so that may be a little longer in coming. On another note, is there anybody out there thinking about scaling up by 150% to build a 1/96 Emilé Bertin for Battlestations?
Hey Webwookie: I am going to put my old dot matrix printer back into working order. Tractor feed, takes wide paper on a roll. I just need to pick up a ribbon and a roll of paper and maybe we could print out some plans on a single sheet! By the way, did you recieve my last email? Looking forward to seeing you. Knight
Sounds good. I think I did receive your e-mail but I have still been sifting through my backlog of legitimate e-mails received over the past few weeks (there's somewhere around three or four hundred I still need to read).
LOL! I understand. My email talked about when you come out here. I do not recall if I mentioned that the best hobby shop around here is Awsome Hobby in Stafford. They are willing to order anything I need! My new motor controller for the MOG arrived. I have not had a chance to install it. That is the last part she needs to sail unarmed. I am working on finishing my basement right now and had to shut down the dry dock! UGH! It was the cleaning out of the old stuff laying around that I found that old printer. OPS! I fear that I am getting a little off topic. I am looking forward to printing out full size plans!
Nah, I'm thinking it's about time to let the Spahkreuzer retire. I recently found documentation saying that the Spahkreuzer class actually had only one rudder, and two skegs outboard to help stability and prevent the ship's back from sinking lower in the water while at speed, just like the fixed outer two "rudders" that Schnell-boats have. With only one rudder, Spahkreuzer's main advantage is neutralized. It's still a formidable opponent, but not quite the monster it once was.
OT: Which highlights a big problem with the hypotheticals. Lack of reliable documentation. Especially with German and Japanese designs where much of the documentation was destroyed.
Actually, the documentation was IN conways, written in the text description of Spahkreuzer. The person who built the original simply didn't read the text.
correction, it is NOT in the description in Conways. One of the members has a book that describes the rudder layout. If a second source is found that agrees with this book, Spahkeuzer will have to be changed. Until then, I'm hoping people don't mind letting a new guy run it until he can transfer the guts and retire the hull, which was poorly built to begin with.
The 2D DXF files will work great for me. Just let me know when all of the drawings for the hull are ready... I may be able to move on from there and do all of the hull components so they are ready, and do any necessary components for the superstructure later if that helps improve scheduling. I will be doing the hull of my Iowa before I do any superstructure. By the way Kotori, Sounds like you guys had a great combat display over the weekend... EXCELLENT!!![]
