The opened areas of master parts were filled with modelling clay and the filler reservoirs were added to the ends: Next is to make the mold boxes and add mould locating pins. Serkan -
Thanks Bill, I have used standard "Revell Plasto" putty in blue tube which is very brittle. To get nicer raised panels with finer width I think a better adhesive and thinner filer is needed (maybe liquid filler like Mr. Surfacer 500?) which should not penetrate below the masking film. Serkan
-
The excessive putty was removed using fine sand paper: Some small repairs are needed especially on lower surface panel lines. But this is not a big problem. Next step will be preparing the mold forms. Serkan

After a long break due to 3D CAD modelling activities I am back with some more progress in real world. I have decided to add raised panel lines as the original Italeri/Testors kit has. To add these panel lines first I have used masking film with cuts where the raised lines will appear; And after then I filled these slots with putty; Similarly I did some fixes and repairs on tail cone parts: To be honest I have not tried this method before and hope that it will work 😁 Next step will be sanding the excessive putty upto desired panel line height and removing masking films.

Recently I have received considerable amount of private messages about the current status of Italeri A-12 Oxcart and Revell Flanker conversions. To be honest I made no progress on both since I have jumped into virtual modelling world. But now it's time to go back to real world... Today I did some progress on Italeri/Testors Oxcart conversion and reported here: I will continue to update this thread in parallel. Serkan

I have started to create solid surfaces to be printed. Here are the first images of fuselage shell: Drawing the interior parts will be challenging but achievable... 🙂 Serkan

Thanks for this link. This was also my expectation what I have seen from all these videos before starting 3D modelling.

Thanks for your suggestion Tony. I will make some test prints using ejection seat model which is enough detailed to see output quality. The support structures will be added by checking the isolated islands before sending the jobs to printer. Maybe I should print in 1:48 even in 1:32 scale to overcome this issue 🙂 Currently I have no idea how to add and print panel lines to surface. Serkan

The headrest, D-Ring and T-Handle were added: Next will be the parachute and belts (which will be the most difficult part). Serkan
-
The rail rollers and knee guards were added as well... Next improvements will be the headrest, D-Ring and cable cutter handles... Serkan
-
The seat cushion and survival kit were added: Next will be the rail rollers and knee guards... Serkan

From "EjectionSite.com" "This is a Lockheed Design which is not much different from the Stanley designed Lockheed C-2 (later modifed into the S/R-2) seat which preceded it in other aircraft [Note: the C-2 seat was used in the very early A-12 and SR-71 Blackbirds as can be seen in the cockpit of A-12 06925]. Some of the differences between the C-2 and the SR-1 seat include the omission of the leg guards and arm restraint nets which were used on the C-2. Due to a fatality which occurred early in the SR-71 program where a crewman was killed when his helmet impacted the headrest of the seat during a structural breakup, some of the C-2 seats were equipped with a headrest extender to more closely fit the seat to the crewman."

Having put this amount of work in I'd expect @Serkan Sen to keep them firmly private and sell either the files with a strict license or just to sell the printed model or parts. It is too early to say anything about availability of the parts or the files but definitely I will not put them into public area. In case of selling the parts or files the money will directly go to charity/foundation account as a donation. Serkan

Me too Bill!.. But I have fear of failure at printing parts. Therefore I am continuously postponing it by adding more details on model. 😁 Here is an update on seat modeling: Next will be the seat cushion and survival kit.. Serkan
-
It shouldn't be an issue (at least between Elegoo Mars and Anycubic Photon) with using proper setup. I have bought Anycubic resin for my Mars but haven't tried yet. Serkan

Why not? 😎 Ok, as the last improvement of this year I have started to model early version of C-2 ejection seat... The main skeleton/structure of the seat is almost ready: I hope in one day I will be able to print them out...🤔 Otherwise what I will have be only a very well detailed 3D CAD model...😁 Happy modelling in new year!.. Serkan

The front fuselage of all three A-12 variants were generated: A-12: Oxcart M-21: Mother Ship A-12B: Titanium Goose The main front fuselage was designed to let building all derivatives using proper replacement parts. Serkan

Thanks Nikolay, I have seen that there are some aftermarket Blackbird resin seats. But I may suddenly decide to model my own Lockheed C-2 seat 😁 I need to find some reference photos of rear cockpit detailing. For forward cockpit instrument panels I will refer to A-12 flight manual. I am trying to stop myself starting J-58 modelling. It will lead enormous modelling effort on engine bay area which will cause significant delay in this project. Maybe I should do it later as an upgrade after the first printed model is ready. Serkan

Oops!.. I forgot to give my Christmas gift 🙂 Let me introduce the A-12B "Titanium Goose"... to be continued.... Serkan

The price is very good nowadays. Maybe I should order second one to speed up printing parts 😁 Serkan

Thanks Robert, I am also very happy with the progress I have made so far. Many times I was at the edge of abandoning the project and going back to kits waiting on the bench. I have checked Jeffrey's project but I haven't seen further progress since long time. My aim is to create all the versions printable in all scales. 1:32 A-12B "Titanium Goose" would be great to have 😁 Serkan
-
Finally wing model was completed. Adding all fillets were a bit challenging but now seems reasonably good. Any identified mistakes can be corrected relatively easily. And here are all parts together: I keep the next step as surprise. Any guess is welcome 🙂 Serkan

Hi Nikolay, I was really wondering why you were not reacting this thread since long time 🙂 Thanks lot for your compliment. I am improving my modeling skill day by day. It will definitely take long time to print all the parts but I have no time constraint. I have almost completed the basic model for A-12 which will be the base model for A-12, A-12B and M-21 derivatives. The landing gear bay and assembly will be also challenging. Serkan
