    @lgardner - glad to know you came through OK.

    @gblair - you would not see the wing spar. The wing on a T-6 is a separate construction, that bolts into the hole in the lower fuselage. Having been in the back seat of several T-6s, I can assure you that whichever version you are in, when you look down, you see the top of the wing - there's a couple holes where the control wires enter the wing and the retraction wiring enters the wing, but that is it. When there was a crash at Reno in a T-6 race back in 1978, the "high" airplane - which entered a high-speed stall when the inexperienced dentist flying it went wing vertical - fell into the lower airplane, with its wingtip hitting the lower airplane at the wing/fuselage junction. When the lower airplane crashed, the impact tore the entire wing off the fuselage and you could see it was complete (until a moment later when it wasn't). So take that into consideration when you are figuring out more stuff to put in - I can tell you in 1/48 you're not going to see much of what's beneath the foot rails, even if you have the canopies open/

    Super job on the 3D printed items, my friend @gblair!

    Amazing to see how small /thin you can print with a resin printer, George @gblair

    Thanks, Spiros (@fiveten) and John (@johnb). The print is still very fragile, so I'm not sure how useful they will be. I broke off one of the legs just trying to assemble the seats. More experiments today.

    Hi, Tom (@tcinla). I wasn't sure about the wing spar. The kit fuselage has a box-shaped area going laterally across the front cockpit. It is the area that forms the wheel wells in the wings. The rest of mold behind the box-shape follows the contour of the wing, so no problem there. I didn't think much, if anything, would be visible down through the floor once I put the framework in. I have primed the area using black paint, and then will spray in the cockpit color over it. Finding photos looking at the floor in the cockpit are impossible to find. I managed to find one photo that catches the rudder pedals, and you can tell that the floor below isn't solid, but that's about it. Even the Dash-1 has no photos or diagrams of the area. I guess they didn't want pilots messing around down there. The resin seats are still a work in progress. They were designed for a very large radio control plane, so they are extremely fragile when scaled down to 1/48. The sides and back are so thin that I get unusable prints about half the time. I broke the support legs just test-fitting the seat for size in the cockpit. Still some more experimentation to do before I try using them in the model.

    I really wanted to get the cockpits sorted today so I could move forward, so I spent a lot of time doing small things. Since the Quinta T-6G rear instrument panel wasn't going to work with this SNJ-3's earlier, simpler panel, I wanted to build a replacement that would mirror the 3D-ness of the Quinta panel. I cranked up the wayback machine and dug out some instrument decals from Revell/Monogram and some instrument bezels from Reheat. I was really worried about the decals, but they worked fine. The bezels were a little fiddly but also worked fine. Photos tomorrow after it dries.

    I think I have finished work on the floor frame. I added the foot troughs, and replicated the angle foot stop at the rear of the rear seat troughs. I sprayed some black primer over the frame in preparation for the interior green.

    I spent a lot of the afternoon printing some parts that might work in the cockpits. All of these parts came out extremely fragile, so I am not sure I will be able to use them. There are several college football games tomorrow that I want to watch, so I may need to see what I can get done during halftime. Cheers everyone.

    These are definitely fragile parts that you printed out. The rudder pedals look extremely realistic too. I'm amazed at just how fine the 3D printer will make things. You are becoming well versed in it's use.

    The IP is also looking very nice. I have never seen any of those PE bezels before. They look as if they could be a tad bit fiddly and if I were to try using them, chances are the "carpet monster" would be well fed !

    I like what you have done to the floor and how you replaced the rudder troughs. Also having the dash 1 book is a very valuable reference. I think you are spot on with your thoughts about the seats too. What you said makes perfect sense. I didn't think about a G load factor with them. It would become very important, especially when the aircraft was rated with each crewman's weight at 200 pounds. Pulling 5 G's would mean the seat would have to support at least 1,000 pounds... and plus they have a built in safety factor that would exceed this number. Incredible when you think about this from that standpoint.

    Enjoy the games tomorrow, and I look forward to your next postings. These 3D seats you printed out are simply amazing. The rudder pedals are too. Having a printer like yours is a very handy tool to have.

    Thanks for stopping by, Louis (@lgardner). Things are moving slowly, but I figure that when all of this prep is done that things will move quickly. The 3D printer is starting to be more predictable and fun, but I still get unexpected results sometimes, and I am still dependent on getting the print files I need from somewhere else. I have created my own print files, but only very simple things.

    G's are fun. Training students to deal with G's was fun in T-37s. Not many G's in C-141s until I started flying airdrop. Then you get to pull G's in a much bigger plane.

    Looking forward to your joint P-51 build. I have my notepad ready.

    Your cockpit looks wonderful so far, my friend @gblair! Love all extras you have added!

    All the extras do add a lot to this already beautiful cockpit, George @gblair

    Thanks, Spiros (@fiveten) and John (@johnb). As usual, I am mired in getting all the parts ready and not really moving the forward very quickly. Hopefully soon.

    Take your time, George @gblair
    Preperation is a very important aspect here.

    Great instrument panel, George. Those tiny bezels will add even more to it.

    I have a short update for today. On Sundays, my wife and I go to our kid's house and we have a lunch and then play board games after. Of course, the rest of the fun consists of playing with our 3-year old granddaughter. Bottom line is there isn't much time for hobbies on Sunday.

    I used some white Gator glue to attach the bezels to the instrument panel, then put a dot of Looks Like Glass in the middle of each instrument. A little touch up paint and it is ready to go. I sprayed some AK Real Color US Interior Color on the fuselage side walls, as well as the cockpit framework. I added a little dark gray to the mix and lightly sprayed the vertical frames to simulate shadowed areas.

    Most of my free time was spent trying to get some parts printed for the cockpit. So far, the parts I have printed have proven too fragile to use. The files I am using to print the parts were designed for a quarter scale RC plane, which is very large. I have to reduce the size of the files to produce a print that is 93% smaller than the original. Sometimes the resized files won't produce a viable print. So, the framework around the seats was originally about 1" in diameter, and the seat frames in the plans were reduced to RC quarter scale, or about 1/4". Now imagine taking the framework that is scaled for RC and further reducing it in size by 93%. You end up with supports that are so thin that it is impossible to get the seats ready for installation without breaking one or more of the them. I really like the look of the seats, which are accurate for a T-6/SNJ, so I plan to keep trying to get something usable.

    I should have more time to work tomorrow, so hopefully more progress. Cheers everyone.
