upupandaway Posted January 7, 2008 Share Posted January 7, 2008 Where are those mini warheads? I think I could use some of those in the kit (the hold-somebody-ransom-option-in-order-to-get-back-the-one-million-you-payed-for-it). If it´s evil, it´s gotta be REAL evil. (and don´t say you can´t do any real mini-warheads in 1/32...) Quote Link to post Share on other sites
Zactoman Posted January 8, 2008 Author Share Posted January 8, 2008 Thanks Chris, it's a neat insight into your technique. As you say, not too diferent from most but, the result is! Whenever I've tried scribing I've really struggled to: i/, get the line thickness consistent. ii/, get the line depth consistent and iii/, manage to get rid of the ridge of plastic created as I draw the scribing tool through the material. Do you find that scribing the resin is different to plastic? I can see how sanding will remove the ridge but don't the freshly engraved panel lines and rivets just fill with waste material again? That certainly seems to be the case when I've tried. Perhaps I'm not being patient enough. Chris, on average, how many times would you say you make a pass along any given line? Twice, three times, more....? Perhaps I'm trying to make a line too quickly or I'm pressing too hard. Any insight you can offer will be invaluable my friend. Thanks again for taking the time to explain your techniques. :wacko: So many questions! Hurts my brain...Where to start??? The resin I've cast this part in does scribe very similarly to plastic, so the technique is similar. I tend to scribe with the tool tipped back at about a 30 degree angle. I make each pass with light enough pressure that if I slip off the line I'm babely scratching the surface. This is a comfortable pressure for me to create the scribe lines, but also makes fixing mistakes much easier. When possible I try making passes from each end of the line. This helps me to control the depth near the end points of the line and also helps minimize depth inconsistencies that result from unequal pressure and chattering. I make several passes with each sized point, beginning with a sharp compass point. I increase the depth with each larger diameter but tend to finish slightly shallower than my end goal. Once I've reached the final width and approximate depth I smear the black (Stabilo 'All') pencil into the line. This helps me to better see the width of the line and also seems to act line a 'release agent' for the next step, the sanding. Next is the wet sanding with 1200 and sometimes 2000. Some debris ends up folding back into the line and can be removed with a tooth brush, or I'll often make a few more passes with the final diameter scribe tool, just applying enough pressure to remove the pencil and debris. At this point I also check for consistant depth and if need be scribe it slightly deeper. The final few passes I use minimal pressure, but enough to burnish and smooth the inner surface of the line... More pencil and it's done. Sounds like a lot more work than it is. Once I'm finished with the scribing and ready to mold or paint the part I take a wet tooth brush to the model and remove all the pencil. Now some pics! Some panels drawn in Illustrator. Poked with a compass point. I smear the pencil on after each step and each segment of each line. Dymo tape as a straight edge. The holes created by poking make nice start/stop points... There you have it! ;) Quote Link to post Share on other sites

Pete "Pig" Fleischmann Posted January 8, 2008 Share Posted January 8, 2008 Chris! Dude-You are the man. Please tell me how you rivet. Getting consistently even-spaced rivets in a straight line befuddles me sometimes. For example, I have yet to figure out how to evenly space rivets around a round or oval panel. Any thoughts Yoda?

jenshb Posted January 8, 2008 Share Posted January 8, 2008 Nice trick on the pencil-grease. That's some of the cleanest scribing I've seen. Following this thread with interest. Jens Quote Link to post Share on other sites

Barry Murray Posted January 9, 2008 Share Posted January 9, 2008 Dude! That is one of the best scribing tutorials in few words i have ever seen! Kudos! Bar. Quote Link to post Share on other sites
foxmulder_ms Posted January 9, 2008 Share Posted January 9, 2008 Zactoman I know you are all in 1/32 scale but but but but why not 1/48. Since I have no idea casting resin, is it too hard to cast 1/48 when you have 1/32 already? i mean you have already done all the reasearch.. Quote Link to post Share on other sites
Aggressor Supporter Posted January 9, 2008 Share Posted January 9, 2008 Love seeing more of the panel line work! Quote Link to post Share on other sites
rom Posted January 10, 2008 Share Posted January 10, 2008 Fantastic work!! Will you post pics of the casting process? I think it could be very instructional for all of us.... What's next?? 1/32 Mig 25? Rafale?.... Quote Link to post Share on other sites
Supertom Posted January 11, 2008 Share Posted January 11, 2008 Chris! Thanks for sharing your scribing technique with us! It's finally given me the idea on how to scribe some of my stuff!!!! Quote Link to post Share on other sites
Berkut Posted January 11, 2008 Share Posted January 11, 2008 Yeah chris, it it possible to resize it down to 1/48? Or does that mean super lot of work? I would totaly loooooooooove to have one in 1/32. But i am 16, and it can sevirely damage my already tight budget. Quote Link to post Share on other sites
flateric Posted January 11, 2008 Share Posted January 11, 2008 (edited) Chris - can you say what was used as basis for model geometry - proportions and cross sections? Scaled up Italeri kit or you could make some measurements at the Western Museum Of Flight, before NG has taken it back from there? To my knowledge, no detailied drawings were (and will be in the nearest future) released due to NG and MDC legal agreement taken after ATF winner decision. As another rivet counter (in the case with YF-23) I can say that Chris made unbelievable job of getting into every panel line and fastener. They are not only where they shoud be, their number is the same as on the big PAV! Can't wait till it will be aviable for purchase!

Zactoman Posted January 11, 2008 Author Share Posted January 11, 2008 Thanks for all the nice comments everybody! Much of the panel line and rivet layout was done in Adobe Illustrator and transferred to the model using the techniques I described on the previous pages and in the riveting article that Berkut was so kind as to provide a link to... As for the overall shape... I did heavily rework the 1/72 Italeri kit which was my main reference, but also used every other piece of reference available to me including every model, photo and drawing I've found. I was lucky in that while the plane was still at WMF I managed to get lots of pics (though I wish I had more! Especially of the cockpit!!!). While I was there I asked if there was any way to get pics of the top of the plane and the staff was kind enough to loan me a VERY tall ladder (I'm afraid of heights and it must have been 16 if not 20 feet!). As I mentioned on page 1 of this thread: "I hand carved it from blocks of 12lb. sign foam that were pinned together. Spackled, primed, puttied, primed, puttied, primed, puttied, primed, puttied, primed, puttied, primed, puttied, primed, puttied and primed until I was happy with it." I left out a lot of the "filed, sanded, nit-picked, filed, sanded, nit-picked, filed, sanded, nit-picked, filed, sanded, nit-picked, filed, sanded, nit-picked, filed, sanded, nit-picked" part of it. Though I'm very happy with the shape I doubt it would survive a wind-tunnel test... ;) Back to the shop now...Casting A-7 and Su-27 parts and trying to make progress on the 23 between things...I've started cutting holes in the fuselage to add vents! :wacko: Quote Link to post Share on other sites
Icchan Posted January 11, 2008 Share Posted January 11, 2008 Chris, that is some beautiful work. I want to get one but it's going to be quite some time before it's affordable; will this be something that's a short-time offer (like the F-16XL conversion) or will you have a more extended production akin to your Corsair and Flanker bits?

Production quantity and span will depend on many factors, so we'll see... :) Quote Link to post Share on other sites
flateric Posted January 12, 2008 Share Posted January 12, 2008 (edited) Chris - BTW, before PAV-2 was re-painted for the first time by WMOF staff, and it was in original colours, I've noticed some extra curved panel lines behind the canopy. Also, are you going to replicate that complicated inlets boundary layer suction system pattern? I've broken my head trying to calculate accurate proportions of these numerous dot squares (made with laser perforation on the actual aircraft)?

Zactoman Posted January 19, 2008 Author Share Posted January 19, 2008 Yeah chris, it it possible to resize it down to 1/48? Or does that mean super lot of work?Since this is a completely hand-made model I would have to start from scratch to do it 1/48. True, a lot of the research will have already been done, but actually making the patterns is extremely time consuming.Besides, 1/48 is too small. My eyes aren't that good... ...are you going to replicate that complicated inlets boundary layer suction system pattern?Yes, I'm going to do it all! I'll be using a fine mesh pattern for that. Same as what I used for the Su-27 FOD guards, and same as the engine bay cooling vents pictured below.Thanks for the great drawings and other info you've provided Flateric! BTW, for anybody who hasn't checked it out yet...Go take a look at http://www.secretprojects.co.uk/forum/index.php ! Some pretty cool stuff and lots of interesting reading!!! Belly is almost finished. Engine air turbine exhaust holes, ECS details and APU vent ( :wacko: ). Engine bay cooling vent and fuel vent. Quote Link to post Share on other sites

geedubelyer Posted January 19, 2008 Share Posted January 19, 2008 Zactoman, dude,.....would you mind stepping into this gentlemans laboratory for a minute please? He would like to take some of your DNA so that he can clone you. :o That way, we can get other projects like a 1/32nd scale Eurofighter Typhoon created to the same stratospherically high standards.............
