BiggTim Posted February 3, 2015 Share Posted February 3, 2015 Maybe I missed this, but what software are you using to create your CAD files? Rhino? Solidworks? Tim Link to comment Share on other sites More sharing options...

Timmy! Posted March 5, 2015 Author Share Posted March 5, 2015 How's about an update?! Here is the progress after a few uninterrupted days in the shop. Several more foam parts have been cut and have done a few more in acrylic. Also the 3d printer has pumped out few parts while I was at it. Here are the representative parts hastily placed together to give the idea of the construction. The acrylic bulkhead that incorporates some detail for the nose gear well. The acrylic is hard and stable but quite brittle. Sometimes a miss calculation of the feed of the bit and I get a little bit of chipping of the detail. Although I will be able to repair this without too much effort. Here's the rear cockpit bulkhead set into milled recesses of the foam fuselage side. Again the fuselage side with a 3d printed gun shroud. The gun shroud in place..nice fit better than expected and this is before any post mill/print finishing whatsoever. Last one these are two of the three vacuum form molds that will shape the nose section of the Jag; that house the LRMTS. The process is light coat of primer is applied followed by careful file and sandpaper work to remove the primer. As the low spots mark the true shape of the part once the paint is gone the part should be closer to it's nominal size. That's it for now more later. Timmy!

chuck540z3 Posted March 5, 2015 Share Posted March 5, 2015 As posted over at ARC, this build is completely crazy- and completely entertaining as we watch you push the envelope of scratch-built modeling at an extreme skill level. Thanks for all the pics and updates, because I know they can be a real pain to do! Link to comment Share on other sites More sharing options...

Timmy! Posted March 29, 2015 Author Share Posted March 29, 2015 Quick little update. I finished post processing the milled vacuum form molds and pulled some plastic. [/url] [/url] Also I got the 3d printer working here are the cabin pressure valve and safety relief valve. [/url] Better photos coming soon. I have more parts from the printer and the vac parts have been trimmed up. Timmy! Anthony in NZ 1 Link to comment Share on other sites More sharing options...

Timmy! Posted April 2, 2015 Author Share Posted April 2, 2015 The promised update to the last update: Parts, parts, parts all in various stages of finishing. I'll just let the photo's do the talking. Nothing new here just basic finishing and detailing work. Printer parts. Vacuum formed parts. Detailing the acrylic cockpit rear bulkhead. Thanks for watching! Timmy!

Youngtiger1 Posted April 2, 2015 Share Posted April 2, 2015 Man, those 3D printed parts look sharp. Link to comment Share on other sites More sharing options...
Timmy! Posted May 31, 2015 Author Share Posted May 31, 2015 (edited) The latest progress. A few more parts cut and printed. Here's the windscreen frame. The part will hold three separate acrylic clear parts, just like the real thing including a thicker center section. The part in the printer. The part with supports attached. I'm really happy with the print. I managed to get the channel for the canopy seal to print perfectly. The parts so far. No clean up and just set together. Getting close to having enough parts to start some assembly and surface detailing. That's all for this one. Thanks for checking in. Timmy!

geedubelyer Posted May 31, 2015 Share Posted May 31, 2015 That is a fascinating creation Timmy! I can't remember ever seeing a 3D print like this before. The interior skeleton is amazing. It looks like the tips of the internal webbing make bolt heads inside the canopy framing. Is that correct? I look forward to seeing you get to the assembly stage. Cheers.

The support structure is calculated by the printer software. I can be 100% automatically done by the software or, as I have done, tell the software where I want the supports to touch the model. However, the do not coincide with fasteners...you are looking at really roughly freed part. Just as a note on my construction so far. The biggest problem I was having with the hand built version was maintaining the symmetry of shape from the left side to the right side of the model. The machining I'm doing provides a symmetrical and dimensionally accurate starting point. I'm not trying to get truly finished parts out of the machine. I'm trying to do machine work up front and will get on to finishing once I have enough parts to complete a subassembly. I'm working on the section forward of the intakes as a single or possibly two part assembly. It may turn out to be a stand alone model, like a cockpit display you see at air shows from time to time. Also this will be the joint where the two version diverges. That is everything aft of the intake lip, with only minor differences, if common to the single and two seat versions. Anyway that's a much greater answer to your question, but there you go. NavyF4s and NORMCO 2 Link to comment Share on other sites More sharing options...
ClumsyDude Posted May 31, 2015 Share Posted May 31, 2015 I don't want to know how long it took you to generate a 3D render of something as complex as that canopy seal - it looks terrific, the kind of detail that will make the model look really awesome. Riveting build! Cheers Jim Link to comment Share on other sites More sharing options...
